How to open a long short message from scratch

It may be a virus, or it may be a system failure after long-term use of the mobile phone.

The recommended grid machine is to restore the mobile phone to its original state.

The method is as follows:

1, back up important information in the mobile phone, such as photos, phone books and various records.

2. If you have a memory card, use a computer to download a 66 10 original card file and search Baidu to find it.

3. Enter: *#7370# on the mobile phone, and follow the prompts to start the grid. If the mobile phone password is required, please enter the mobile phone password (the original password will not change to: 12345) and complete the grid.

4. Format the memory card, copy the original card file downloaded before to the memory card, and finally put it back in the mobile phone.

This should be no problem.
