InfoVision m5 12 is slow and unsatisfactory. What's the matter?

It is recommended that you try the operation according to the following steps:

1. Try to turn off the battery for charging (when the battery is charged and discharged at the same time).

2. Clean the contact point between the battery and the mobile phone battery, and check whether the contact point is damaged (poor contact can also cause this situation).

3. Connect the data cable to the computer for charging (whether the charging head is damaged)

4. Try to replace the data cable (is there a problem with the USB cable)

5. Replace the battery (regardless of whether the battery is aging or damaged)

6. Please back up the data of your mobile phone (phone book, SMS information, multimedia materials, etc.). ) and restore the factory settings of the mobile phone: Settings-Privacy-Restore the factory settings (whether the troubleshooting software causes the failure).

If the problem persists, it may be a system or hardware problem.
