d. After selecting the flashing package, click the "Next" button to back up the phone data to avoid data loss. Before the backup starts, allow the flashing assistant to read text messages, contacts, and other records on your phone. Then click the "Flash" button to start the backup and flash, and wait for the flashing to finish slowly.

3. Contact the mobile phone repairer to solve the problem.

I guess the landlord is using a Samsung Gaishi series of mobile phones. Gaishi series is a better series of mobile phones, its cost performance is very high, the current use of the problem is due to the limitations of the memory and the size of the memory card limitations, some large games, a huge number of application software colleagues will be illuminated into the machine crash or the loss of information inside. The precautionary measure is to clean up the memory of the phone in time and disinfect the virus, and do not install too many games or applications.
