Before you buy a new cell phone or new tablet,
please try the following procedure to repair your device. First charge
your battery, backup your important data if possible and in most cases
take out SIM and SD card. It is impossible to recover your data after
doing a hard reset, so online backup is always important. For all of
your data, a backup should be done on an external device, hard drive,
raid system or media. With or without insurance, if your cell phone
lost, damaged or stolen at least your invaluable data is backed up in a
safe place.
