All Android phones come with built-in recovery mode that is separate from the original operating system.
The recovery mode is used to access different features of the phone without accessing the phone’s OS.
The main function of the recovery mode is to fix the phone while staying away from the faulty OS of the phone.
1. Lets get started, press and hold power button to turn off your device.
2. When your phone is turned off you have to press and hold both Volume down button and power button at the same time.
3. Wait for LG logo to appear and let go off the buttons.
4. Now there should be a recovery mode menu on your screen.
5. Now you know how to put your phone in Recovery mode, congratulations!
Recovery is included on a separate partition from the main Android OS on all Android devices.
You can boot directly into recovery mode and use it to factory reset the device, delete the cache partition, or apply software updates. It can help you fix your device.
