How to rearrange the Samsung Gear S3's app drawer and widgets

10
Samsung Gear S3

You can easily tame some of the chaos that is the Gear S3's app and widget situation.

With so many apps, services and utilities available on Samsung's Gear S3 smartwatches, it's easy to get carried away while setting things up and all of a sudden be in a stressful situation. Dozens of apps across multiple pages of the app drawer sit beneath a dozen pages of widgets to the right of your watch face — but thankfully you can clean up this situation to make it easier to get just what you want.

While you can't altogether hide or delete most of the pre-installed apps on the Gear S3, you can rearrange them in a way that puts what you want front and center, leaving the rest to the background so it isn't in the way. Here's how to get it done.

Samsung Galaxy Note 7 fires, recall and cancellation: Everything you need to know

Samsung Galaxy Note 7

Here's all the information you need about the Galaxy Note 7 fires and recall — the events that led to the phone being discontinued.

After months of twists and turns since September 2016, the Galaxy Note 7 story has (effectively) come to an end. The core of the situation is that Samsung faced a serious issue with Galaxy Note 7 phones that have a high propensity of batteries failing and in many cases catching on fire, leading to personal and property damage. In the original, pre-recall Note 7, hundreds of phones worldwide had critical failures.

Following initial reports of fires the phone was recalled officially in the U.S. once, and Samsung launched exchange programs in other countries. But the new models continued to see further issues, with replacement catching on fire in early October. This led to Samsung telling Note 7 owners to stop using the phones and return them, before permanently discontinuing the Note 7 worldwide. Shortly thereafter, the U.S. CPSC officially issued a second recall. The Note 7 is well and truly finished.

Here's everything you need to know about this unprecedented situation.

Switching from iPhone to Android: Everything you need to know

65
 Everything you need to know

So you've seen the light and are switching from iPhone to Android. Welcome! Here's what you need to know!

Switching from iPhone to Android can be a bit daunting. If you're unpacking a brand new Pixel or Galaxy S7, or something else equally exciting, let us help you get set up quickly and easily!

If you've never used an Android phone before, there are a few things you should know before taking the leap (even though it's the leap home).

There's a learning curve

Switching from iPhone to Android isn't the same as upgrading the from the iPhone 6s to the iPhone 7. It's more akin to switching from Mac to PC (though not as drastic). General functions are still similar, but major Android phone manufacturers will often have proprietary user interfaces, distinguishing them from other makers.

Therein lies the rub. There is no single version of Android in the way that there's only one iOS. Companies take the Android operating system and interpret it and mold it according to their vision, meaning you'll get a different experience using a Samsung phone than you would using an HTC phone or an LG phone.

Though all Android operate similarly on a fundamental level, it's the little, finicky difference that set them all apart, so it may take some getting used to.

If you're just about to turn off your iPhone and put your SIM card into a brand new Pixel, Galaxy or something else shiny, here's what you need to know!

Turn off iMessage!

When you message other iPhones from your iPhone, they'll communicate via iMessage when you're connected to the internet. This is different from regular SMS texting, and if you leave iMessage turned on on your iPhone, many of your texts will still be routed through that service.

If you're on your new Android phone, you won't receive any of those messages. You need to disable iMessage before making the switch! (And while you're at it, turn off FaceTime.)

You might have to buy your apps again

If you have pay-upfront apps on your iPhone that you paid for, you'll likely have to buy them again from the Google Play Store if you want them on your Android phone.

The Google Play Store and the App Store are completely different entities, and the apps they house are made for different platforms. Some of the apps you had on your iPhone may not even be available for your Android phone and vice versa. That said, if you're subscribing to a service like Spotify or Evernote, you just need to download the app and log in on your new Android phone to get going.

You may need to re-sync your life

If you have all of your contacts, calendar events, photos, documents, and more synced with iCloud, and everything's on your iPhone, you'll likely have to re-sync everything on your Android phone.

Android's version of the cloud is housed in your Google apps, like Docs, Gmail, Contacts, Drive, and more. When setting up your Android phone, you'll set up a Google account and from there, you can actually sync some of your iCloud content with your Google account, so that you don't have to re-enter all of your dates, contacts, etc.

What you'll need to bring with you

You don't have to leave your life behind on your iPhone. You can bring your information with you so that you're not taking hours to populate your Android phone with all of your stuff.

Contacts

Yes, Google and Apple are direct competitors and the two biggest competitors in the mobile game, but neither makes it too difficult to switch teams. Rather than manually enter all of your contacts into your new Android phone, you can export your iPhone contacts in a few different ways.

Calendars

If your calendar is flush with events, it'd be a major pain in the behind to have to add them all in again once you've made the switch to Android. Luckily, all of your calendar info resides in files called ICS, which are widely used and easy to transfer.

Photos

Like most of us, your phone is probably your primary camera. You'll want to take those precious memories with you when you leave the land of Apple, especially if you're planning on erasing and selling your iPhone after. We recommend using Google Photos. Most Android phones have Google Photos pre-installed (and if not, it can be downloaded from the Play Store) and it's a super quick and easy process.

Documents

If you use iCloud Drive, then you probably have a few documents socked away and you might want to get rid of iCloud Drive in favor of Google Drive when you switch to Android. Transferring those files is easy if you use the iCloud Drive and Google Drive desktop apps!

Manufacturer tools

Some manufacturers have their own tools to help you migrate your information from a computer. So if you have all your iPhone data on a computer, you can add it to your Android phone using the maker's tool.

You won't be able to add an iPhone backup to your Android phone, but you'll be able to drag and drop contacts, music, and more from your computer.

Samsung Smart Switch

You'll need to use the desktop client to be able to move your iPhone data to your new Samsung phone. It's essentially the same as moving files around on your computer, but by connecting your Android phone to your computer, you'll be able to transfer everything right to your phone.

LG Bridge

LG Bridge lets you interact with your LG phone on your computer, where you can easily transfer all of the stuff you want to bring over when you migrate from iPhone to Android.

Pixel Switch

Each Google Pixel comes with a USB-OTG adapter that allows you to quickly and easily transfer files, contacts, calendar entries and even iMessages from an iPhone to your new Android phone.

Just remember

At the end of the day, switching to Android from iPhone is nowhere near as difficult as switching your writing hand, or even using that hand to write a test! An Android phone still performs the same basic functions you're used to: making calls, messaging, surfing the web, playing games, etc.

It may take some getting used to, but you might find yourself feeling freed with all the customizable options that Android has to offer (I took three days to decide my home screen layout when I got my first Android phone after switching from iPhone).

Have fun with it and really do your research before buying your first Android phone so that you make sure you're buying what's best for you.

How to restore your apps and settings to a new Android phone

16

Got a new phone? Awesome! Here's how you can restore your apps and settings from your previous device.

Google has always synced calendar events, contacts, Drive documents, Gmail settings and other account-related information across devices, and since Android 5.0 Lollipop the company started offering the ability to restore apps to a new device. With Marshmallow, the feature was expanded to include app data as well as system settings, with all the information stored in the cloud.

If you're using the Google Now Launcher, your home screen background, icon and widget layout as well as folder structure is now saved to the cloud, allowing you to restore your settings to a new handset and retain your home screen layout.

Where does all this data get stored? Google is backing up the app data to Drive, allocating 25MB for each app. Data used by the backup system doesn't count toward your storage quota. Meanwhile, developers can choose to select what app data gets stored in the cloud.

Here's how you can restore your apps and settings when moving to a new Android phone.

There are millions of books and movies for you to escape into, and music for every taste and time. While it may still seem odd to some of us to buy movies on your phone, or to buy an album that doesn't come in a sleeve, there's plenty here to love and enjoy, and we're here to help you make the most of the entertainment side of Google Play.

How to use Google Home to call an Uber

How to use Google Home to call an Uber

Google Home is supposed to be a digital assistant, so why not use it to call a car?

One of the first integrations announced with Google Home was Uber, meaning you can use your new smart connected speaker to seamlessly call a car to get you and your friends where you need to go. The problem, as is always the case with voice-activated interfaces, is that you don't know how this all works until you try it — and when it comes to Uber, you don't want to be messing around with calling actual people in actual cars to come pick you up.

That's why we did the work for you. Here's what it's like to call an Uber from your Google Home, and what you need to be ready for when you do it for the first time.

Adding an OnHub router to your Google Wifi network

22

Your Google OnHub is now a bigger Google Wifi node.

Google Wifi is a great product. It's easy to setup and easy to make any adjustments or additions to the wireless network in your house. But it's not the first Wi-Fi router from Google. That'd be the OnHub.

Many were worried that the OnHub would be abandoned when news of Google Wifi was revealed. With good reason — the OnHub is a great product, and we've seen great products wither and die before. Thankfully, that didn't happen. We were told during the initial product briefings that an update was coming that would let the OnHub and Google Wifi work seamlessly. Google later made a similar public announcement when the required software updates started rolling out to OnHub users.

I've been using a network with an OnHub and three Google Wifi node for about a week. "Seamlessly" is a great description of how the two different products now work together and act the same.

What changed for the OnHub

The software. Basically, all of it.

The OnHub now performs exactly like any Google Wifi would, through the same interface in the same Google Wifi app. it is now a bigger Google Wifi mesh node. The unique features are still there: I can still wave my hand over the top of my ASUS OnHub like a Jedi to prioritize a device for an hour. You still have 13 antennas (six for the 5GHz radio, six for the 2.4GHz radio and a signal booster) that aren't designed for a straight line long range signal like many other routers in the price range. But the brains inside are now the same as we see used for Google's mesh network product.

You still have the strong antennas and unique features of your OnHub, but the way they work and how you set them up has changed.

You can use it the same way you would use a Google Wifi node, too. It can be added to an existing network as a Wi-Fi bridge (things worked exactly as expected and setup was easy), added to an existing Google Wifi network as a new node (we'll talk about that in a bit) or as a NAT Gateway router attached to your modem or ethernet service — which is how I recommend using it.

Performance in every configuration was similar to the older software when the OnHub was a stand-alone router. The range seems a little more broad than a Google Wifi unit, but they are very similar and if you're inside the magic bubble (I say the number is 45 feet in any direction) you'll have pain free wireless with any modern wireless interface. Go much further and you'll see things drop off, slowly at first but there is a definite distance where things just quit. That depends on what's between you and the unit, but in general, I've found one OnHub can cover my average-sized home. When added to an existing Google Wifi network, you have one more node that can stretch great wireless to even more corners and crannies in your house. It was shockingly flawless in this configuration and performance was equal to or better than a Google Wifi node would have been.

The setup process

You're basically following the same process as you would for Google Wifi — unbox the product, open the app and follow the simple step by step instructions. After you've read a few hints, though.

The biggest difference is that you'll need a software update. If you've been using your OnHub and have switched to the Google Wifi app, you already have the correct software. If you haven't had it up and running or you just got it, you'll need to take it out of the box and attach it to your modem or ISP gateway and let it download some software. Get it connected and let it sit for about 30 minutes, then open the Google Wifi app and make sure it's showing in the app. You're now good to go.

Once you update the OnHub software, you set it up the same as Google Wifi through the same app.

You can add an OnHub to an existing Google Wifi setup, but I found that the setup process complains about doing it and suggests you try using the OnHub as your NAT Gateway instead of a mesh bridge and sometimes just refuses to start the setup process. Once the setup does commence, the rest is easy and it just works. The good news is that you won't have to be playing with the setup more than once. The bad news is that you might not have any luck the first time. In any case, the setup that it recommends — building your Google Wifi network with the OnHub installed first and as the gateway to the internet — was a breeze and everything worked great the first time. I haven't touched the setup since.

Setting an OnHub up as a bridge on an existing network is similar to adding it to an existing Google Wifi network. You're told that this is not an optimal setup (but not given any real details why) but you can tap your way through anyway. The reason why, by the way, is because it can create what's called a double NAT (Network Address Translation). Most of the time your first router can send data through a bridged router seamlessly, but not all the time. It's something I'm more than happy to discuss in the comments if anyone wants to know more. With that out of the way, once set up and running it works fine. You just have to be careful when changing advanced network settings.

The way I recommend you set things up is to unhook all the things you have on your existing network and build your mesh network around the OnHub. Plug it into the modem and power, let it get its software updated if it needs it, and start the process in the Google Wifi app to build a new wireless network. You won't have the app fussing at you, and you'll have a strong router near the modem that still has a free Ethernet port. That leaves any other Google Wifi nodes as the smaller and easier to place newer units.

An extra Google Wifi unit can be a wonderful thing

This is the most exciting part. OnHub routers can frequently be found on sale and will end up a good bit cheaper than the single Google Wifi unit. It's a great way to add a fourth node to a network and can give you the freedom to be creative.

Google Wifi units (including the OnHub) are wireless other than the power connection. Plug the first one into your modem, and place the rest anywhere within range. But you can use a wired connection between one or all of your nodes. And Ethernet cables can get long.

Wi-Fi in the kid's (or your) treehouse is an entirely different level of awesome that's easy to do if you have an extra Google Wifi node.

A Google Wifi three pack can make for damn near perfect wireless everywhere in an average home. Even the porch and driveway. But many of us have a workshop or pool or other areas around our house where good wireless would be a great addition. A 100-foot, 200-foot or even longer CAT-6 cable can be attached to two Google Wifi units to stretch them far apart. You can even buy long cables that are designed to be buried directly in the ground. It works great, and you don't lose the wireless speeds you would trying to cover 200 feet of distance — Ethernet is fast, too.

I suggest setting the unit up wirelessly first while it's in the range of everything else. Once finished, unplug it from the power and take it out to the deck or treehouse and connect it to the cable you've run. Power it up, give it a minute or two, and enjoy the fast Wi-Fi for your phone or your Chromecast or TV.

It's late December. It's far too cold for me to be outside scratching away at the frozen dirt with a shovel. But I've tested this with a 200-foot cable and a Chromecast audio setup and it works just grand. I'm looking forward to a nice Springtime project that's easy to do and can make a great home improvement.

How refunds work on Google Play

6

We all have purchases we regret.

We buy apps that aren't as great as we hoped. We buy books and movies we don't like. Our kids buy things we didn't want them to. Co-workers get into your phone while you're in the bathroom and buy dirty movies. Things happen, and if you need a refund on Google Play, there are ways to get one.

But as always, there are caveats and hoops to jump through.

What is encryption?

23

Encryption can be a very complicated subject, but getting a grasp of the basics isn't difficult.

Recently, we've had a few questions about encryption. We've talked about how Android incorporates encryption and the changes that Nougat brings, and to get the most from those discussions an understanding of the basics is a must. Let's talk about those basics for a bit.

What exactly is encryption?

In its simplest sense, encryption is changing the way information is displayed, so that it is masked, and the only way its true form can be viewed is with a clear set of instructions.

You're using encryption every day and may not know because it can be transparent.

There are plenty of ways to do this, especially when that information is digital and stored on a computer or a phone. If you've ever received a zip file or Microsoft Office document that needed a password to view, it was encrypted. The data you wanted to see was placed inside a container (think of it as a folder on your phone or computer) and the container was password protected. This method can be scaled up, even to include an entire disk or partition. To access anything on the encrypted partition, you need to unlock it with a password.

Another way to encrypt data is to physically alter what is displayed when you view it unless you can decode it. Let's say I built an app that you could type a phrase in, and it would convert all the letters into numbers from 1 to 26. You could type "this is a message" into my app and save it. If you tried to look at what you typed without using my app, it would look like this:

208919 919 1 1351919175

But my app knows that 1 equals a, that no string higher than 26 is valid, and has access to the operating systems dictionary to make sure the letters are correct because 11 could equal aa or k depending on what word it's used in. So if you open that file in my app, it reads normally.

At its core, encryption is designed to make something hard to read unless you know how to look at it.

Now do something like reverse the order, add 13 to numbers between 11 and 15, omit the whitespace and drop random data that won't be read every few letters. The file would be impossible to read without sitting down and trying to figure out how the text was manipulated through trial and error. That's what an encryption algorithm does. It helps a program turn data of any kind into a jumbled mess that can be easily decoded by the algorithm itself but would take a lot of effort and time to crack without it.

Computer algorithms can do things that are far more complicated than my simple example and take a lot less time than it did for me to count on my fingers. This type of encryption is usually referred to as a cipher and the method the algorithm gives to decode it is called a key. If you have ever used PGP or GPG encryption for a message or email attachment, you've used this type of encryption, known as cipher-keypair encryption.

Both types of encryption — container based or cipher-keypair — are common and in use on our Androids. Sometimes both are used and encrypted data is placed inside an encrypted container. Taking our data and encrypting it then making sure the things that we want to have access can decrypt it is extremely complicated. Thankfully, those complicated parts are handled by the hardware and operating system and all we need to do is have the right key in the right place and/or supply a password.

Encryption and Android

Android supports both types of encryption we talked about above in the OS, through the network and on the storage. As an application platform, it can also support encryption methods from third-parties for things like secure folders or encrypted messaging and email.Android also supports hardware backed encryption. That means there is a component inside the SoC (System on Chip — where the CPU and GPU live) that exists to help encrypt and decrypt data on the fly. The actual key to decrypt files is stored on this device and any user interaction — a password, a fingerprint, a trusted device, etc — that is used to access encrypted data is really asking the Secure Element in the hardware to do the job. Since Android 6.0 Marshmallow, all cryptographic function can be done using this Secure Element and the private key (the token used to encrypt and decrypt data) is never exposed to software. This means that without a token to present to the hardware, the data stays encrypted.

Android is built with encryption in mind and your data can be safe and inaccessible to anyone but you.

In your Android settings you might also be able to keep the system encrypted every time it boots up until a password is entered. Having a phone running that's filled with encrypted data is pretty safe, but halting the boot process until a password is entered prevents access to the files and acts as a double-layer of protection. Either way, your login password (or PIN or pattern or fingerprint) still accesses data through the secure element and you don't have a way to get the actual private encryption key, which is the only thing that knows exactly how the data was scrambled and how to put it back together.

Your messages and web browsing can be encrypted, too. You've probably seen many sites in your browser use the HTTPS header instead if HTTP. HTTP stands for Hypertext Transfer Protocol and is the protocol (think rules) that is used to send and receive data over the internet. HTTPS stands for HTTP over SSL (Secure Sockets Layer), which adds an encryption standard to the protocol. Anything you enter into the web browser is "scrambled" with a public key you downloaded from the website when you got there, and only the private key — which the web server has — can unscramble it.

Whenever you're entering any information you consider private on the web make sure you have a secure HTTPS connection.

Data sent back to you is scrambled in a way that only your unique version of the public key can unscramble. You don't need to do anything except visit a secure page that has the HTTPS header. Your phone makes sure the server is really who it claims to be, using a certificate, and encrypts and decrypts data on its own through the browser app.

Messages that are encrypted usually require an app you need to download from Google Play. The Pixel is the lone exception, as it comes with Allo installed which supports encrypted messages. Another great messenger that does the same is Signal. Signal offers what's called end to end encryption, which means that the app assigns keys for individual contacts or groups and only you can decrypt a message sent to you. BlackBerry Messenger is considered secure by many, but since there is only one global key and every BlackBerry device has it, there's debate about how secure it is. BBM Protected is available for groups who require higher encryption or end to end encryption. Apple's iMessage is also encrypted end to end, but only when everyone is using an iPhone.

You use these apps like you would any other messenger — add a contact and send messages. The only difference is that those messages can be encrypted so only the two parties involved can read them.

Is encryption bad?

Encryption does nothing on its own. It's the user that makes it "dangerous."

Some folks in some governments claim that having encryption technology available to the end user (that'd be you and me) is dangerous because it makes it impossible to monitor communications of "persons of interest". The argument can sound convincing when we're told that terrorists communicated for months using a service like Facebook or WhatsApp. But encryption itself is not a danger to anything and without it, none of our online transactions would be secure, and we would have no guarantee that our chats are private. At the same time, all the private information on our phones would be easily accessible by anyone with the right tools and motivation.

If we give up any right to have encryption, we are giving up our privacy. Privacy is scary to the government because they want to know when we're not being completely law-abiding. The notion that potential criminals can be caught and some crime prevented is great, but it requires that the law-abiding citizens who want to safely buy from Amazon give up that right, too.

Only you can decide if you think encryption should be taken away from the private sector for the greater good, but you do need to know that the technology itself does no harm. Like most things, it can be abused by the user.

This really only scratches the surface of what encryption is and how it works. there are plenty of online resources that go in-depth with all the technical details. But this should give you a basic understanding of it all, and the next time you see someone talking about the merits of end to end encryption or advantages of a particular platform, you'll be able to understand and participate.
