Android is a modern operating system that powers 70% of tablets. However, users periodically need to restart Android. And if the usual turning off and on of the device does not cause any difficulties, then special reboot methods are sometimes inaccessible to the average user. The fact is that such information is not indicated in the instruction manual. In addition, Chinese devices are common today, the accompanying documentation is written in hieroglyphs.

Why do you need to restart your smartphone or tablet?

There are several ways to reboot:

• regular;
• hard (reset to factory settings);

A simple reboot is usually used to free up the gadget’s RAM, which is gradually becoming clogged with third-party programs. This problem is especially common in devices running Android 4.3 and earlier versions. A regular reboot is also used when short-term problems occur caused by software malfunctions. To reboot the device, you need to hold down the power button and select “Reboot” in the window that appears. If the device is frozen, a forced reboot will help, which is carried out by simultaneously pressing the power, volume and Home buttons.

If a regular reboot does not help to cope with the slow operation of your smartphone or tablet, you should use a factory reset. However, you need to keep in mind that all installed applications will be deleted, so before performing the procedure, it is advisable to make a backup copy of the software using a standard tool from Google or a third-party program (for example, Titanium Backup). To completely reset the device you need to:

1. Turn off the device completely.
2. Press and hold the Home button until a slightly modified Android logo appears - a green robot with an open lid on its stomach and an exclamation mark.
3. The device will boot and all settings on it will be reset to factory settings.

This method does not work on all devices. Many manufacturers provide a factory reset and allow users to perform this procedure using a menu.

On stock Android (without third-party add-ons), you can reboot the device in a simpler way:

1. With the OS turned on, hold down the power button.
2. In the menu that appears, hold your finger on the “Turn off power” item for a long time.
3. Agree to enter safe mode.

If none of the above methods work on your device, you can reset the settings via Recovery.

Reboot into Recovery

Recovery is a kind of analogue of the BIOS interface used on mobile devices. With its help, you can perform a complete reset of the system settings, delete all data on the memory card or the device itself, install unofficial firmware and much more.

The most commonly used Recovery systems are:

1. TWRP. It has a nice interface, supports touch control, and has wide functionality.
2. CWM. It has almost the same set of functions, but does not support touchpad controls. But CWM has better compatibility than TWRP, so it is used in more devices.

The procedure for logging into Recovery depends not on its version, but on the phone or tablet model. Thus, in smartphones from Samsung, you need to hold down the central mechanical key along with the power and volume up buttons. For Nexus series models, you need to hold down the volume down and the power key and select Recovery.

For tablets based on MTK processors, there is a utility called Mobileuncle Tools. With its help, you can enter Recovery by simply selecting “Boot into Recovery”. In addition, this program allows you to configure important parameters of the device, including turning off unused mobile frequencies and adjusting processor operating modes.

There is also universal software that works on almost all devices. The Fast Reboot program has become widespread. It allows you to instantly perform a so-called virtual reboot - restarting all system services without disrupting the functioning of the operating system.

This feature is usually used to quickly clear RAM or to eliminate errors associated with incorrect operation of third-party software.
