If you enjoy modding your Android device with root utilities, custom ROMs, and Xposed modules, then there's a good chance you've had to factory reset your phone when something went awry. Plus, when you're switching ROMs, it's always recommended that you wipe all data, so us modders spend a lot of time restoring and tweaking various settings.
No matter how far technology advances, battery life continues to be an issue. Powerful new hardware is introduced each year, but smartphone batteries only get a few extra milliamp-hours to compensate.
One of the biggest causes of smartphone battery drain is the mobile data connection—particularly if you live in an area with poor reception. But, chances are, you don't actually need this connection most of the time, because you're probably connected to Wi-Fi for a good chunk of the day, which uses far less battery life.
Starting with version 6.0 Marshmallow, Android now supports fingerprint scanners natively. This change has effectively opened the floodgates, and now almost every flagship Android device includes a fingerprint scanner out of the box.
Out of all the new functionality introduced alongside Android 6.0 Marshmallow, a battery-saving feature called Doze Mode has been the biggest hit. Essentially, Doze waits until your device is laying flat and still, at which point it triggers an aggressive battery-saving mode that drastically increases standby time on your device.
With certain apps and games, it's all about the settings. In order to get your money's worth with one of these, you simply have to take the time to tweak and adjust various options, which is something a lot of users don't necessarily want to do.
Samsung has been on a tear with its flagship devices since the release of the Galaxy S6; The S6 edge, the Note 5, and this year's Galaxy S7 models have all been met with universal acclaim, and even the staunchest of critics have almost nothing negative to say. Almost.
Mobile data is expensive. The internet connection that comes with your cell phone plan is generally limited to a certain amount of gigabytes that can be downloaded before your monthly cap kicks in, at which point you run the risk of incurring costly overage fees.
Android's personal assistant is more than just a sassy backtalker—it's a full-on suite of all the information you could need at a given time. Google Now, as it's called, uses data from various sources to predict what you'll want to know before you even search for it, and it's an amazing experience once you've got everything set up.
You gotta love Android—not only can you replace your default home screen entirely, but there are tons of options that provide alternative methods for launching apps with ease. We've covered some of these options in the past, including an app called Bar Launcher that lets you launch apps from your notification tray—but that one's starting to look a little dated these days.
Ever been in an argument, only to have the other person cop out by saying "I never said that," when you know full well they did? Or how about one of those times when you're sitting in the lecture hall, half dozing off to your professor's monotone ramblings, when your ears perk up because they somehow know you missed something important that was just said?
If you've ever prematurely dismissed all of your push notifications before you got a chance to read each one, you know how annoying it can be to dig through all of your apps to try and find the one with the missed notification.
Android has a single text file named build.prop that determines tons of various system-wide settings on your device. You need root access to edit this file, since it's stored on the system partition—but the various lines of codes it contains are actually fairly easy to interpret and modify.
Of all the new features in Android 6.0 Marshmallow, an automatic battery-saving function called "Doze" might just be the most interesting. What it all boils down to is that if you set your phone down on a flat surface, the device uses internal sensors to detect that it's motionless and not in use, then responds by drastically scaling back battery-sucking services until the next time you pick your phone up.
Back in August, Google unveiled a new YouTube Gaming service meant to compete with e-sports streaming sites like Twitch. At its launch, the service was capable of broadcasting desktop PC gameplay, but when it came to the mobile segment, users were only capable of viewing streams hosted by others.
Manufacturers like Samsung and LG have added their own implementation of multi-window features to Android for years now, but with the release of version 6.0 Marshmallow, Google has finally gotten around to working the same feature into stock Android.
Smartphone games are getting pretty good these days, but they still can't beat the retro appeal of a good emulator. I mean, who wouldn't want to have their all-time favorite console and arcade games tucked neatly in their front pocket? Classics ranging from Super Mario Bros. to Pokémon can all be played at a silky-smooth frame rate on today's devices if you can just find a good emulator to run them on.
You'll have to forgive me if I sound a little overexcited about this, but in my opinion, Google's "Now on Tap" is one of the most innovative™ smartphone features that I've seen in years. Sure, Microsoft heard about the feature being in the works and rushed out a similar Android app so they could say they were first, but that solution pales in comparison to this one.
There are plenty of legitimate reasons that you might want to record a phone conversation. Let's say you operate a business and take orders over the phone, and you don't want to miss an item. Or perhaps you need to jot down some notes from a recent conference call, and things were just happening too quickly in real time.
If you have some photos, videos, and documents that you want to keep completely hidden and encrypted on your Android device, Andrognito is the app you need. We showcased this app in the past, but since then, CODEX has rebuilt it from the ground up with new and improved features.
Make no bones about it—having an "undo" option is a freaking godsend. Whether you accidentally deleted an entire essay, screwed up the shading on a Photoshop job, or sent an email that wasn't quite ready, having the option to undo a click or button-press can definitely be a lifesaver.
Update (February 2019): The methods below will help on older Android versions, but we've recently revisited this topic. So if you have a newer Android phone and you want to get rid of Google, head here.
With all the stress that goes into booking flights and lodging, packing (and not forgetting) everything you'll need, finding pet sitters, and everything else that goes with a trip overseas, there's the added stress of staying connected while abroad.
Ad blocking on Android usually requires root access, but a pair of new browsers based on the open source Chromium and Firefox builds are looking to change this.
With smartphone screens getting bigger by the generation, one-handed mode mods are becoming rather prevalent. Most of these function by shrinking the screen to a more manageable size, but this is actually kind of boring when you think about it.
Ever feel like you're receiving notifications way too late on your Android device? Many Android apps use Google's Cloud Messaging service to send and receive notifications, including Hangouts, Gmail, Pushbullet, Facebook, and even WhatsApp to an extent.
Hangouts is a great cross-platform messaging service from Google that works with almost any device, making it one of the few messengers that can be installed on Mac, Windows, iOS, and Android gadgets alike. With its many useful features, one of the few debatable downsides is its not-so-attractive color scheme.
Keeping expensive mobile devices safe and secure is a priority for most of us, but the process of repeatedly unlocking a phone or tablet can seem like a pointless task. This leads to disabling the lock screen altogether, especially when in a safe place (e.g., home, office, car, etc.).
Widget toggles, or "power toggles" as they're often called, have been around for quite a while. They serve their purpose nicely as an easy way to add switches to your home screen or notification area for functions that don't come with the stock software on your device.
Android Lollipop's new Material Design interface does its best to strike a delicate balance between intuitiveness, usability, and aesthetics. For some folks, though, the use of a lighter color palette throughout the interface disrupts this balance.
One of the more talked-about features of Google's new flagship device is the fact that all of the data on the Nexus 6 is encrypted by default. At face value, this certainly seems like an added bonus for the 6-inch phablet, especially in this day and age with growing security concerns abound. It's definitely something that the FBI is none too pleased about.
On most Android devices, the various volume levels are comprised of either 7 or 15 steps between minimum and maximum. For voice-call volume, alarms, and notifications alike, 7 presses of a volume button will bring you all the way from silent to full-blast. With media controls, you get 15 steps between mute and max.
Google Keyboard, which comes pre-installed on Nexus devices (and is available for all others from the Play Store), is one of the most functional keyboards currently available for Android. With features like gesture-based typing, next-word prediction, and even text expansion macros, it's a very capable form of text input.
Your phone's volume panel is one part of the user interface that usually goes unnoticed to themers and developers. With themes capable of changing the look and feel of the fingerprint scanner, keyboard, and other system apps, this central aspect of the UI seems to get lost in the shuffle.
If you have a custom recovery installed on your Nexus 5, you're able to flash custom ROMs and lots of other cool Gadget Hacks. But when it comes time to receive and Over-the-Air (OTA) update directly from Google, having a custom recovery installed can be a fairly big hindrance—and for the upcoming Android L release, you're going to want to alleviate that.
At the core of your Galaxy S5's hardware lies the central processing unit, or CPU for short. Practically every piece of data, every binary bit, has to pass through your CPU before it can be used to display a video or execute a game command.
Just the fact that you own an Android device means you're privy to an entire world of third-party development. Many of the mods you'll see here on Gadget Hacks can be performed fresh out of the box, but with root and Xposed, the list grows longer. But to truly be able to take advantage of all that Android's massive development community has to offer, you'll need to have a custom recovery installed.
The level of customization that Android has to offer is insane. You can replace the stock keyboard and home screen with any third-party app of your choosing, allowing core experiences to be tailored to fit your needs.
Google has finally announced the newest flavor of its mobile OS, Android L (Lollipop?), and I couldn't be more excited. While we won't see its official release until the fall, there are still some features we can get our hands on right now.
Update, November 12, 2014: Android 5.0 Lollipop is officially out now. If you haven't gotten the OTA yet, check out our new guide on installing the official Lollipop builds on any Nexus for download links and instructions, for Mac or Windows.
