Uncover and wipe
Check the film on the screen first, sometimes the film may affect the touch screen effect. Try to remove the film and gently wipe the screen with a soft cloth to see if the problem is solved.
Clean up and restart
Too much garbage in the mobile phone cache may also cause the touch screen to fail. Go to "Settings" and select "Storage" to clean up the cache garbage. Then shut down and restart to see if the problem has improved.
Restore factory settings
If the first two steps fail, try to restore the factory settings. Please note that this will delete all data, so be sure to back up important information. Go to Settings, select System and Update, click Restore Factory Settings, and then select Clear All Data.
Professional detection
If all the above methods are ineffective, it may be a hardware problem. Don't worry, Meizu authorized service experience center or factory inspection will provide you with professional solutions.
Intimate reminder
Don't panic when you encounter problems, follow the above steps to try. At the same time, it is also recommended to update the mobile phone system regularly to get a better experience.
