There probably isn’t a person now who hasn’t got an absolutely indispensable smartphone in their pocket. However, despite this fact, there aren’t many people out there who know about all the incredible things these devices are actually capable of.

The easiest way to save your battery power

If you choose a black or simple dark background for your screen, the automatic pixel highlighting will turn off, and you’ll notice that your device keeps its charge for much longer. This feature isn’t available for all Android devices yet, but it’s already implemented on most Samsung smartphones and tablets. Give it a try!

Text-to-speech

Not only can you read this article but you can also listen to it if you have an Android device. So if you prefer to hear incoming information rather than see it, go to Settings -> Accessibility and turn on the Text-to-Speech Output option.

Smartphone remote control

Just go to Settings -> Security -> Device administrators, and check the boxes next to Android Device Manager, Remotely locate this device, and Allow remote lock and erase. Now if you lose your smartphone, you can locate and block it without losing your data via this website.

Turning on Guest Mode

If you would like to temporarily give your phone to another person yet keep your personal data confidential, use Guest Mode. Swipe down from the top with two fingers, and touch the user icon on the upper right. The Add guest icon will appear, and you’ll be able to choose which actions the person handling your smartphone will be allowed to take.

Screen magnifier

People with poor eyesight often have no idea how much this feature can help them. Just go to Settings -> Accessibility -> Magnification gestures. Then you’ll be able to zoom in on any part of the display just by tapping it.

Control your smartphone with head movements

There are situations when you just have to use your gadget but your hands are otherwise occupied or it’s just too cold outside to take your warm gloves off. However, there’s a solution for this! After installing a free app called EVA Facial Mouse you’ll be able to control your Android device with movements of your head! The detailed guide on installation is here.

A secret game

Starting with Android 2.3 Gingerbread, Google puts a small secret present for users into all their devices. However, finding it may prove to be quite difficult. Here are instructions on how to do it despite the odds. First, go to Settings and choose About phone or About tablet. Quickly tap Android version several times, and when a small marshmallow shows up on the screen, quickly tap it again, and a special mini-game will open.
