There are not many problems with using android phones, and there are not many software installations.
However, recently, mobile phones have frequently crashed, and wifi connections have also crashed.

Even the most basic functions are not enabled, and sometimes the phone is black.

Forget it. reset it.

Images, the most important thing, must be backed up !!, Use a memory card to copy the file. Or upload it to your computer. At the same time, regular backup is required !!
The phone is not worth much. The information is very important !!!

Use the qq browser for cloud backup and synchronization.

Qq, chat records are all deleted, basically not important.

3. Restore

It's easy. There is a factory reset setting in the System menu, and you can just restore it directly.
After the system is restored, the space occupied is much smaller, 15 GB of storage, and more than 5 GB storage.
I think the android mobile phone has a benefit: 1 dual-card dual-standby, 2 supports memory cards, 16 GB card easily, and 3 supports changing the battery.
The battery of the mobile phone has been used for one year. Basically, it will not work, and the charging will not be enough.
At this time, a compatible battery was changed, and immediately recovered. Continue service.

Mobile phones have become our closest partners and keep our partners young.
Don't bother yourself. Please serve you well. It is estimated that this mobile phone will continue to serve for more than a year. In addition to the low resolution of the camera on the mobile phone, there is no reason for replacement. Once the battery is changed, the standby mode is no longer a problem.
