There are three tiers to Android customization: things you can do by default, things you can do with ADB, and things you can do with root. While root is still pretty tricky to get, ADB mods just got a lot easier. Back in Android 9, Google added a feature that allowed you to w ...more

Silence spreads over these mountains like nothing I've ever felt. If I didn't have Moby blasting in my earphones, there'd probably be no other sounds around. Well, except for someone, Phil probably, murmuring in a nearby tent just low enough to make his words indiscernible. W ...more

Whether it's a short road trip or an 18-hour flight, our phones are now essential travel companions. No longer do we need a GPS unit, maps, cameras, camcorders, or even boarding passes. However, not all phones are created equal in this regard. Some are more suited for travelin ...more

Stories are everywhere in social media today, but that wasn't always the case. In 2013, Snapchat introduced the world to these temporary windows into our daily lives. Since then, stories have infiltrated other popular apps. However, to stand out, you can't solely rely on the a ...more

Many apps claim to record phone calls on Android, but very few actually deliver. There's just too many different devices floating around out there for one app to be able to support them all — or so it would seem. The development team at Boldbeast Software may have finally sol ...more

The Galaxy S9 is full of minor improvements and revisions that come together to make it a worthy upgrade over the Galaxy S8. One such improvement is facial recognition, which Samsung has fortified with machine learning and the inclusion of another sensor. The result of these e ...more

Shortly after we detailed several indicators that the Galaxy S8 Oreo Beta Program would begin rolling out in the month of November, we now have a full changelog for the update. Many users on Reddit already found references to the beta in the Samsung+ and Samsung Members app. ...more

Samsung's recent TouchWiz rebranding didn't really change much — the skin is still as bloated as ever, and the UI still uses tacky accent colors. But while you can't fully remove TouchWiz without rooting, there are ways to make it look a lot better. We all know the Galaxy S8 ...more

Your smartphone stays with you everywhere you go, so it's only a matter of time before you spill coffee all over it or drop it on the ground. For some of you, it has already happened, perhaps even multiple times. That's why we thought it was important to find out which flagshi ...more

As Android owners, we ultimately have to look at our device and ask the difficult question: "Where the hell did all these applications come from?" We're all guilty of installing the latest and greatest app or game, but at some point we come to the realization that we're digit ...more

Android 11 is here. Prior to Google dropping the naming scheme, this would have been a dessert with an R name (maybe Rice Krispies Treat or Red Velvet Cake) — but nope, just plain ol' Android 11. And after months of betas and a global pandemic, it finally debuted a little over ...more

For those not used to it, working from home can be a difficult transition. Everything around you can be a distraction, and distance from your boss and coworkers means less pressure and incentive to get things done. So it's not surprising to see a major drop in productivity dur ...more

Android comprises an entire ecosystem of apps, games, functions, and features, so it would only make sense that it has its own lexicon. Words, phrases, and acronyms that didn't exist ten years ago are now used in an off-the-cuff style by developers and support technicians acro ...more

On a PC, you can play sound from multiple apps at once. It's great, but it can also be confusing — there's a volume slider in each app, then the system-wide one, and probably another knob on your speakers. To avoid this dysfunction, Android only has one sound stream for media. ...more

It's a done deal. KitKat is the shit, and everyone wants in on it. Unfortunately, the Samsung Galaxy S3 won't see any of Android 4.4's features incorporated into TouchWiz for some time, as we're still on a 4.1 version. Still, we can throw a few of KitKat's features onto the d ...more

Organizing contacts is a bitch, especially on the iPhone. Some contacts will have multiple entries, you can only delete contacts one by one, and certain types of contacts can't be deleted at all. If that isn't enough to make you pull your hair out, then I don't know what will. ...more

When an app is acting buggy, you head to its App Info page in Settings and hit the "Force Stop" button. And since all software has bugs, this is quite the handy feature. But now that Samsung's Settings app got a makeover with the Android 10 and One UI 2 update, you might have ...more

I'm sorry your mom hates you now, but it's pretty hard to forgive someone who forgets to say "Happy Mother's Day." Your poor ole ma could've spent anywhere from 10 to 20 hours popping you out, so the least you could do is set aside two minutes every year to say thanks. If you ...more

The hugely successful S10 series of flagships may be a tough act to follow, but Samsung has proven that it's up to the task with the Galaxy Note 10. The latest phablet bearing the Note name is the first of its line to come with an even larger variant, and boasts an eye-pleasin ...more

It's been over two whole years since the Samsung Galaxy S3 was released, so let's face it—our beloved GS3, once an iconic heavyweight in the tech arena, is almost as washed up as Sylvester Stallone. Mine has been suffering from bouts of lag, and the battery just isn't lasting ...more
