Even if it was designed to work at an optimal level, as any tech product on the market, it starts to work slower than usual after a period of time and even to freeze whenever you open some applications. For this reason, it is highly recommended to perform a master reset. Whenever you notice that your phone is performing at an undesirable rate, all you have to do hard reset the device back to factory default settings. This hard reset procedure offers you the chance to keep all your desired contents of the SD card, so only elements that are stored on the internal memory will be affected. Before commencing, you should make sure that the device has sufficient battery (above 60 per cent) and backup everything important. You can do this on a hard drive or any other external accessory.
There are two ways to restore the phone to its original state. The first one implies the fact that the user still has access to the Android menu, and that the phone is responding to your commands:
- From the main screen you have to select Settings
- From the Personal are, you will have to select Backup & reset icon.
- You have to touch the Factory data reset.
- Select Reset Phone (remember that you will lose any personal data on your phone)
- Choose Ok and the process will begin. Your phone will reboot with the factory settings.
- Your phone will restart and it will start up with the factory settings.
The second method uses the hardware buttons and works when the phone is unresponsive and you can`t access the menu of the device. Make sure you have the battery charged because if the phone turns off unexpectedly during the process, your device may be affected. Now you can try the following steps:
- Turn off your device.
- Press and hold the Volume UP and the Power button.
- Your phone will reboot in Recovery mode. Use the Volume buttons to navigate in the menu and the Power button to select an option.
- Using the Volume buttons navigate to the Wipe data/Factory reset option and select it using the power button.
- Your phone will reboot with the factory settings
