Android Oreo brings big improvements to your phone's security and privacy

Oreo is the most secure version of Android yet.

Every time Android gets an update, there are changes that we can't see. There is a lot going on behind the home screen and it takes an army of developers to keep a piece of software as intricate as Android running. With Android Oreo, some major changes are in the background that bolsters user security and privacy.

As users, we are mostly concerned with what we can see or do ourselves; things like being mindful of installing random apps or not opening email attachments from people we don't know. But the heavy lifting goes on behind the scenes and work to prevent any of the malicious content we might run across from gaining a foothold is a priority. Oreo has a long list of changes and features on this front.

  • Android Oreo no longer supports SSLv3 (Secure Sockets Layer version 3.0). SSLv3 is outdated and has been proven insecure, and at the recommendation of the IETF (Internet Engineering Task Force; a group that sets a sort of standard for internet communication) it's been completely dismantled in favor of a newer communication security method, TSL (Transport Security Layer) 1.2.

In addition, when you try to connect to a server that isn't correctly using TSL 1.2 Android Oreo will no longer attempt to fall back to a previous version as a workaround. Your phone running Oreo just won't connect to unsafe web servers, and that's awesome.

  • Android 8.0 applies a Secure Computing filter to all applications. The list of ways an app can directly communicate with the kernel has been reduced. These have traditionally been a popular method to attempt a kernel exploit to gain admin-level privileges. It's harder than ever for any type of malware to get root.

  • WebView objects now run in multiprocess mode. Any apps that get content from the Web now show that content in its own isolated sandbox, where it has no access to any app data. A website that tries to steal your information will find no information to steal!

  • Apps that are running can no longer assume other apps are in a generic location and will need to ask the system itself to pass data along to their actual source directory. Not knowing where to find an app means it's much harder to exploit any vulnerabilities in it.

  • Android Oreo now handles your unique identifying data differently. Prior to Android 8.0, a unique Android ID was generated when a device was first set up. This ID was constant, and developers could use it to verify a user when retrieving data from the cloud. With Oreo, an ID based on the app developers signing key (a tool used to verify an app is original and hasn't been tampered with) our Android Advertising ID (a function of Play Services and something we can erase or opt out of) and the actual device ID. Every instance of the Android ID is now different and isolated to the app that generated it.

This ups the ante on user privacy, as a developer can't track users of one app with another app or share user data based on ID with any other apps.

This applies to every app, not just apps targeted to Android O. But there is a caveat: apps installed prior to an Android O system update will still use the old ID. You'll need to uninstall and reinstall them if you want to use a unique and safer way to verify your identity.

  • The "unknown sources" system of installing apps from outside of Google Play has been completely revamped.

More: Here's why sideloading apps is safer with Android Oreo

Google does other things to help cut down on malware and security scares, too. We've recently seen [Google Play Protect]http://ift.tt/2ra6K4V) as a new branding for retail devices covered by Google's machine learning-enabled application scanning service, and monthly patches for security exploits help update Android itself against new security issues.

We still should be mindful of what we install, but it's good to know that the Android security team has our backs.

Samsung may launch the Galaxy S9 as early as January

Samsung could be accelerating its timetable for the Galaxy S9 to combat the iPhone 8.

Samsung usually unveils its Galaxy S flagships at Mobile World Congress, which takes place at the end of February. That wasn't the case this year, with the company delaying the launch of the Galaxy S8 to roll out additional safety measures following the Note 7 debacle.

If a report out of South Korea's The Bell is to be believed, Samsung is looking to launch the Galaxy S9 earlier than usual, possibly even in the month of January. The publication says that the unveil will be followed by a global launch sometime in mid-February.

The Bell is basing its hypothesis on display shipments — display panels are usually shipped out two to three months before a phone's launch, and Samsung Display is set to kick off shipments of OLED panels for the Galaxy S9 in November. For the Galaxy S8, the panels started shipping out in January.

Samsung sold over 20 million units of the Galaxy S8 and S8+ globally, with the company seeing a 15% uptick in flagship sales from the previous year. An accelerated launch window allows Samsung to make the Galaxy S9 available in stores by the end of February, giving it a decent headstart over the competition. Not that Samsung needs it, judging by the sales figures.

The upcoming iPhone launch, however, could have influenced Samsung's decision to move up the launch of the Galaxy S9. The iPhone 8 is expected to sport a bezel-less screen, and while Samsung has a flagship that's set to become available later this year in the Galaxy Note 8, it looks like the company wants the Galaxy S9 to join the fight as soon as possible.

Not much is known about the Galaxy S9 at this point, but the phone is rumored to sport a similar dual-camera setup as the Note 8.

YouTube TV: Everything you need to know!

YouTube TV is here, and you probably have questions.

It's always exciting to see a company like Google offer something new, but YouTube TV is not the first time this company has tried to do something innovative with streaming video. Here's what you need to know about Google's latest efforts to shake up television as we know it.

What is YouTube TV?

Think of YouTube TV as an internet-based cable television subscription. For a monthly fee, you can stream live television directly to your phone without needing an account through your local cable company. You can use this as a way to watch live television when you aren't at home, or you can completely replace your home cable service with YouTube TV.

Aren't there other apps that do this right already?

As a matter of fact, there are three rather popular services offering similar services. Sony's PlayStation Vue lets you watch and record live TV across many different screens, DirecTV Now is a satellite-free alternative to cable companies, and SlingTV exists as an alternative to watching your favorite shows with a cable box.

YouTube TV is looking to compete with these services by offering a price point in the middle of these services, with expanded features a promise of more consistent streaming video quality.

What channels do I get with YouTube TV?

Currently, YouTube TV is offering:

  • ABC
  • CBS
  • FOX
  • NBC
  • NBCSN
  • USA
  • FX
  • FreeForm
  • Oxygen
  • Bravo
  • MSNBC
  • Fox News
  • CNBC
  • FXX
  • FXM
  • SyFy
  • Fox Business
  • Local Now
  • Disney
  • Disney Junior
  • Disney XD
  • The CW
  • E!
  • Universo
  • Universal
  • Sprout
  • National Geographic
  • Nat Geo Wild
  • Chiller
  • ESPN
  • ESPN 2
  • ESPN 3
  • ESPN News
  • ESPN U
  • SEC ESPN
  • CSN
  • Fox Sports
  • BTN
  • NBC Golf
  • Telemundo
  • FS1
  • FS2

YouTube TV also includes YouTube Originals, which are shows and movies previously available only to YouTube Red subscribers.

There will also be the ability to add networks to your subscription for an additional fee. Currently, Fox Soccer Plus and Showtime are on the list of add-on networks to be available at launch.

Can I record shows with YouTube TV?

You can! YouTube TV includes a "Cloud DVR" service that allows you to record multiple shows simultaneously so you can watch them later. This feature includes a commercial skipping feature if you're watching a recorded show, available with a simple tap in the YouTube TV app.

This Cloud DVR service comes with unlimited storage, and videos you have recorded can only live on your account for nine months before they need to be erased.

How many people can use my account at the same time?

Each YouTube TV account allows you to connect up to six accounts in a family plan for no additional fee. Currently, no other live TV streaming service supports six simultaneous users as part of the base price, and each of these connected accounts will get separate recommendations and offers based on their viewing habits. This means you kids can watch all the Pokemon they want and it won't interfere with reminders about Game of Thrones or Football.

So far, Google has not mentioned any need to prove those six people live in the same house or share any other Google services.

What do I need to use YouTube TV?

As it stands YouTube TV works on just about everything with a screen. Android and iOS apps are available, as well as a website for watching and controlling your account.

If you have a TV with a Chromecast dongle or Google Cast service embedded, you are able to stream anything from YouTube to your television easily.

How much does YouTube TV cost?

Right now Google is offering a flat rate of $35 per month for YouTube TV. Each add-on network will run you an additional $10 per month.

This monthly plan does not include any contracts or commitments, so you can quickly cancel the service if you decide you are unhappy with it.

Can I get YouTube TV now?

You can get YouTube TV right now, provided you live in an area with service. Google's plan is to make the service available first in the largest U.S. markets and expand rapidly after the launch. In case you are curious, the currently supported media markets in the U.S. are:

  • Atlanta
  • Baltimore
  • Boston
  • Charlotte
  • Chicago
  • Cincinnati
  • Cleveland
  • Columbus
  • Dallas-Fort Worth
  • Denver
  • Detroit
  • Greensboro
  • Harrisburg
  • Hartford
  • Houston
  • Indianapolis
  • Jacksonville
  • Kansas City
  • Las Vegas
  • Los Angeles
  • Louisville
  • Memphis
  • Miami-Fort Lauderdale
  • Milwaukee
  • Minneapolis-Saint Paul
  • Nashville
  • New York City
  • Oklahoma City
  • Orlando-Daytona Beach-Melbourne
  • Philadelphia
  • Phoenix
  • Pittsburgh
  • Salt Lake City
  • San Antonio
  • San Diego
  • San Francisco Bay Area
  • Seattle
  • St. Louis
  • Tampa
  • Washington DC
  • West Palm Beach

To sign up so you can be notified of when this service is available in your area, head here and let Google know you're eager to try YouTube TV.

What about people outside of the U.S.?

As is often the case with Google products and streaming TV services, YouTube TV is currently U.S. only and will likely remain U.S. only for quite a while.

In order to launch in other countries, Google needs to secure streaming rights in each country. That kind of thing takes a lot of time, so the current focus is delivering in the U.S. for now.

We'll be sure to update this FAQ as more information becomes available!

Updated August 31, 2017: This article has been updated with YouTube TV's 12 new cities.

Here are the Sony phones that will be updated to Android 8.0 Oreo

Sony will deliver the Android 8.0 Oreo update to 10 phones.

Sony unveiled the Xperia XZ1 and XZ1 Compact earlier this week at IFA, with the phones running Android 8.0 Oreo out of the box. The company also shared the list of phones that will be eligible to receive the Oreo update.

Here's the full list of Sony devices that will pick up the Oreo update:

  • Xperia XZs
  • Xperia X Performance
  • Xperia X
  • Xperia XZ Premium
  • Xperia XZ
  • Xperia X Compact
  • Xperia XA1
  • Xperia Touch
  • Xperia XA1 Plus
  • Xperia XA1 Ultra

Oreo brings a slew of new features, including picture-in-picture support, background limits, notification channels, systemwide autofill API, and so much more.

There's no timeline as to when Sony will start rolling out the updates to its phones, with the company only stating that the timing would vary by region. We should hear more in the coming months. Is your Xperia device set to pick up the update? Let us know in the comments below.

Gboard now lets you use stickers and Bitmoji

Gboard lets you install sticker packs and use Bitmoji with latest update.

The latest update to Gboard adds support for stickers and Bitmoji, giving you more ways to express yourself in conversations. Once you're on the latest version of Gboard, you'll see a tab for stickers in the emoji pane. You'll be able to download stickers from the Play Store — there are both free and paid options available — and install the Bitmoji app if you don't already have it on your phone.

Google has teamed up with its partners to make sticker collections available on the Play Store. These include the likes of Mickey Mouse, NBAmoji, Disney Princesses, Hello Kitty, Garfield, Star Wars, and more. You'll also be able to create sticker packs with your own selfies, like with Allo.

You'll be able to use the stickers and Bitmoji in any app that supports image pasting, and Google also mentioned that it will roll out new sticker packs in the coming weeks.

Marshall upgrades its speakers with multi-room audio

Marshall is adding much-needed connectivity options to its speakers.

Marshall teamed up with Zound Industries a few years ago to roll out speakers designed to look like its guitar amps, and the company is now rolling out new connectivity options. The new speakers will now offer multi-room audio through Marshall's Wireless Multi-Room System, which allows you to control the music playing in any given room though the Marshall app.

The speakers now sport Chromecast built-in, AirPlay, and Spotify Connect in addition to Bluetooth 4.2. Three speakers are being upgraded with the new connectivity options — the $349 Acton, $449 Stanmore, and $599 Woburn. That's a $100 increase from the standard Bluetooth-only editions of the Acton and Stanmore, and a $50 hike from the regular version of the Woburn.

Alongside the wireless connectivity options, all three speakers feature a 3.5mm jack, and the Stanmore and Woburn also come with an RCA jack. There's also a new control dial that lets you choose from seven presets, giving you easy access to your favorite Spotify playlists.

The new speakers are now up for pre-order, and will be available in stores starting September 21.

LG's focus on the V30 cameras is great for pros and amateurs

Manual mode? LOG video? Focus Peaking? A smartphone after my camera nerd heart.

Almost every phone these days comes with at least an adequate camera. Some, like the Samsung Galaxy S8 have exceptional cameras, but it takes a phone like the LG V30 to say that it was designed with camera buffs in mind. The Galaxy S8's camera truly is exceptional, but it's designed to be great for the average phone user, somebody who just wants to open the camera app, take a few shots, and then tweak it with Instagram and start collecting those likes.

The V30 has ease of shooting quality photos down pat. The camera launches quickly and shoots with no lag, capturing great photos with nearly every press of the shutter button. But for people that want to take the time to frame up their shots and make sure the lighting is just right, the manual options available on the V30 are second to none.

Video Bit Rate Up to 52 Mbps

For the Pros

A number of the V30's headline videography features are carried over from last year's V20. Those include the use of focus peaking when using manual focus, electronic stabilization for video, and tracking focus. There's also something new, and a first for any smartphone: a special recording mode called LG Cine-Log that will get the video nerds really excited.

Focus peaking is a feature typically available on high-end DSLR and ILC cameras, used in conjunction with manual focus. It highlights the portion of the image that is in focus with a green line, allowing the camera operator to easily see what's in focus without having to jog the focus dial forward and back. Focus Peaking is only available on the main camera, as the wide angle is fixed focus.

Steady Recording is LG's implementation of the third-generation electronic video stabilization tech Qualcomm built into the Snapdragon 835 processor. Steady Recording works by cropping in the video on the sensor to provide a surrounding buffer margin of pixels to move the recording area into should shake or bumps hit the camera.

There's a trade-off, though: the buffer margin required on the sensor means that it's only available for standard 1080p HD video — 4K's pixel area demands mean the software cannot crop in enough to provide sufficient buffer space for the stabilization.

Focus tracking is a feature that's long existed on high-end video cameras and is now filtering its way down to smartphones. This feature allows the videographer to select a focus point (tap to focus, here) and the camera will maintain focus on that object even as it moves around the frame and closer and away from the camera. This allows for more dynamic filming, both from motion of the subject, but also in the camera, while keeping everything sharply in focus.

LG Cine-Log format is possibly the master stroke for video recording on the LG V30. This special video format takes after the popular (with video pros) S-LOG and V-LOG formats you'll find on high-end Sony and Panasonic cameras. If you were to graph the standard video recording brightness and saturation profiles, what'd you'd get would basically be a straight line, with the same value weighting applied to pure black as pure white and 50% gray — all colors and brightnesses are equally represented in the table of values.

In a LOG format, more of that weight is transferred to the middle brightnesses and saturations, giving the videographer more flexibility when editing their footage. It looks rather flat unedited, but when tended to by an experienced video editor you can see much greater dynamic range and image fidelity that might otherwise by lost.

LG's Cine-Log video format is meant for the pros out there, allowing editors more flexibility in producing a quality, professional color balance.

Our early tests with LG Cine-Log have revealed quite a bit of noise in the footage, particularly in the dark at 4K, but noise is hard to avoid at this resolution on a sensor this small (and even high-end Sony S-LOG footage is super noisy in the dark). But then again, the whole point of LOG formats is to give the video editor more control over the final result — if they want to filter out the noise in post production, they're more than welcome to do so, but now they have control over how strongly and in what manner that noise is filtered. LG Cine-Log format is not available on the wide-angle camera which, while not a shock, is also a bit disappointing.

Manual controls offer the same sort of fine-grained control that was present on the V20. You can adjust the shutter speed (a faster shutter will result in sharper footage), ISO (how sensitive the sensor is to light), exposure value compensation (adjust overall brightness), hop into manual focus, and play with the overall blue or orange coloring of the recording by adjusting the white balance.

Hi-Fi Audio controls allows for detailed adjustments to what's recorded by the microphones. The gain slider allows you to adjust the overall volume, LCF (Low Cut Filter) lets you cut out low frequencies (such as HVAC systems, the sound of a train, etc), and LMT sets a maximum volume to prevent loud noises from blowing out an otherwise reasonable recording.

For the rest of us

Beyond all of the pro-level video features, LG has built in a few new enhanced video features for the more pedestrian videographers among us. Those mostly surface in the Cine Video mode (yes, there are three video modes here: Auto, Cine, and Manual).

Point Zoom is an enhanced version of traditional zoom — instead of simply zooming in on the center of the frame, you can specify any point the screen to zoom into. Tap, drag up on the slider to zoom in, and drag down to zoom out. It's worth noting that this doesn't determine the focus point or use tracking focus, so if you move the camera while zooming in, you'll still be zooming in on that point of the frame versus following a subject in the frame. As with any digital zoom, the more you zoom the more the picture quality will rapidly degrade.

Cine Filters are, well, cinematic filters. These let you replicate in-camera a selection of cinematic styles. Some are fairly obvious — "Classic" replicates black-and-white film, including how the color red comes through darker than similarly-bright blues or yellows, while "Flashback" is basically a sepia filter — while others replicate the color grading you'll see in various styles of movies. Want the [blue-and-orange look] of Marvel, Transformers, and DC? Hit the "Summer Blockbuster" filter. Tapping "Romantic Comedy" will give you more reds, "Noir" goes heavy on the blues, and "Thriller" turns down the brightness and washes everything in dark blue. They're all neat effects, and LG thankfully included sliders to let you adjust the intensity of each in case going full Michael Bay wasn't the look you wanted.

All of this combined leads to what should make the single best video-recording smartphone on the market. LG positioned the V20 in that position, and the V30's additions on top of that — Cine-Log, improved lenses, and more — make it a worthy successor.

Oh, and it takes photos, too

While LG has done much to position the V30 as a videographer's delight, they didn't forget that this is also a camera you can use to take pictures. There are a number of modes that will satisfy the needs of nearly all photographers, though your mileage may vary on the usefulness of each, and it's helpful to know what these modes do because the name isn't always descriptive enough.

Auto is exactly what you think and how you'll likely use the camera most of the time: point, then shoot. The phone handles all of the shutter speed, exposure, and focusing for you (though tap to focus is here) and all you have to do is frame up the shot. Auto also encompasses auto video record (tap the red button and video begins) and is the default mode on launching the camera app. Auto is perfectly adequate for 99.9% of shots.

Manual for the other 0.1% of photographic opportunities, manual mode is fantastic. Not only does it allow fine-grained control over the white balance, focus (main camera only), exposure, ISO, and shutter speed, it also gives you the option to capture photos in a DNG RAW format. Every other mode, and practically every other smartphone, captures photos in JPG, which is a compressed image format that takes what's on the sensor and reduces the files size by fiddling with the fidelity of the colors and brightness.

An image is simply a grid of pixels with assigned color values that correspond to the light received by the sensor. If you go across a row and a set of five pixels have varying values of red, but they're quite close, a JPG file will say they're all simply the same red because the human eye won't be able to tell. So instead of saying Pixel 1 is this color and Pixel 2 is this other color and Pixel 3 is that color, the JPG says that Pixels 1-5 are all this color. Spread out across 16 million pixels, that can save a lot of space.

A RAW file goes the complete opposite direction. There's no compression — each pixel has its own original value — and instead of color values, the file stores the light value recorded by each pixel on the sensor. The end result is much greater fidelity in editing the image: you can pull details out of blown out whites and pitch-black shadows that are simply lost in a JPG where white is #ffffff and there's nothing you can get out of it. Of course, you need a RAW photo editor (like Adobe Lightroom) to edit those files, but once you get comfortable editing in RAW there's no substitute for photos that you truly care about.

Snap Shot takes advantage of the 18:9 extra-tall screen of the V30, allowing you to frame up a photo with the top half and preview the previously capture photo below. While this is a nice option, it's also worth noting that this forces you into capturing square images. But if you're shooting for Instagram and you're a square photo purist, this isn't a bad option.

Match Shot is two options in one. The first take on Match Shot better matches the name: you can take one square photograph and have that be one half of the photo, and then match up another photograph on the other side. It's not meant to be used as a panorama, instead it's more of an artistic function of matching up two images. The usefulness of this is debateable, especially when you lose flexibility by doing it in-camera. LG does allow you to zoom and reposition the photos after taking both, but once you save it, that's that. Match Shot also supports video, though the saved result tends to be a little uneven.

The better half to Match Shot is taking two photos at once, and with three cameras to choose from there are plenty of options. You can do any combination of the standard angle rear camera, wide angle rear camera, and the front camera (at its default 100° wide angle or digitally zoomed). The best use is in combining the front and rear cameras, that way you can show your instant reaction to whatever is visible through the front camera.

It's worth noting that Match Shot also works with video, so if you want to capture a video of your reaction while skydiving along with the view that you're seeing at that moment, this is the mode for you. Just hold on to the phone.

Framing and composition are everything when it comes to photography, and Guide Shot is LG's tool for photographic consistency.

Guide Shot is the serious Instagrammer's tool. Framing and composition are everything when it comes to photography, and if you've got a signature framing style (say, you take food photos and every one is a from dead above and perfectly centered) then you can load up a template photo as an overlay on the viewfinder so you can frame the current shot to match. It can also be useful for replicating old photographs (think the hilarious "20 years later" family photo where everybody wears the same cloths in the same pose) or famous images (getting that Abbey Road shot juuust right). Like with Snap Shot, you need to be cool with square photos, though.

Grid Shot is like Match Shot, but, uh, a grid. You can take four square photos or videos and they get arranged in a grid. LG's taking advantage of the tall screen here, putting a full-width square viewfinder up top and the 2x2 grid on the bottom. Usefulness is debatable here, but it's a conscious choice to use Grid Shot.

Pop Out is a carry-over camera feature from the V20, creating a photo that layers the standard angle image over top of the wide angle image. There are a few effects you can apply to the under photo (blur, fisheye, vignette, and black-and-white), but it all honestly seems more like a gimmick to show off the dual cameras than anything.

Food might be named for capturing your meal, but it's a mode with a single control and purpose: a prominent white balance slider. We've all done it: whipped out a phone to take a photo of an incredible meal before digging in, only to get an image that's awash in the yellow ambiance lighting of the restaurant. Our eyes adjust to such lighting with ease, but our smartphones haven't always been good at it.

LG put a big emphasis on the color spectrum sensor that they started including way back with the G4, but in truth it's never lived up to their hype because it could never reliably tell what color the lighting actually was. The Food mode is a concession to that, giving the user manual control over the color temperature in an otherwise full auto mode. If everything looks too yellow, drag it towards the blue side. You can't go quite as far as you can with the white balance in Manual, but it's better than nothing.

The makings of the best smartphone camera

LG has touted the V series since the beginning as being all about the media creation experience, and the V30 is the best iteration on that idea yet. LOG video files, manual camera mode, filters and framing for Instagram pros, Hi-Fi audio recording and playback… the V30 checks all the boxes for a mobile media machine.

Of course, it's no substitute for a proper DSLR or an array of high-end microphones hooked up to a sound board, but it was never supposed to be. The V30 is the smartphone for people who work with and love that kind of professional tech and want that same sort of control out of their phone. There the V30 delivers in spades.
