Whenever you notice your device working slower than normal, you ought to try a software refresh. Why? The reason is due to the fact that this process can help you get rid of infections, software errors or simply delete any important data before a resell. Being very similar to a hard drive format on a conventional computer, a soft reset deletes everything and brings back the phone to a working state in a few minutes.
Soft resetting your smartphone is a method very much alike to a hard drive format on a conventional computer. Whilst everything important is deleted, the smartphone will be brought back to a working state in an instant. You need to keep in mind that a backup is recommended before beginning this process. Here is the first method to bring back your device to a functional state and get it up and running without problems:
- From the main screen, you have to select Settings.
- From the Settings menu, you will have to choose the ‘Back up & Reset’ icon.
- Click on ‘Factory data reset’.
- Choose Ok and wait for the device to reboot.
The second method uses the hardware buttons and works when the phone is unresponsive and you can`t access the menu of the device. It is especially suitable for a phone that does not respond to any commands – a frozen display and no reaction to most keys on the keyboard are a clear sign of this. Please do the following in this situation:
- Turn off your device.
- Press and hold the Volume Up key, the Home button 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 button, navigate to the ‘Wipe data/factory reset’ option and select it using the Power key.
- The process will end with the message ‘Data Wipe Complete’.
- Wait for your phone to reboot.
