Hi Sir,

Can you kindly provide the picture for us so that we can make "inverted" more clearly?

If the firmware is not the latest firmware, please update to the latest firmware and reset the phone to factory then test again. If the problem still exist, please provide the config.bin for us to check, about how to get the files, please refer to the FAQ below:

Also, can you tell me how many phones you have in total? And how many of them have the issue.

Thank you for your information in advanced.
Best Regards,
