What should I do if the WeChat, qq and SMS send keys of Nubian Mavericks fail?

Hi!

Hello, I suggest *#406# calibration screen, and enter *#406# calibration screen in the dialing interface. Or perform screen calibration at the time of recovery. Press the power button+turn up the volume button to enter the recovery screen, select the last calibration item, and then select the first item to restart the mobile phone test. Or you can download the latest SD card brush package from the download link of the system rom and upgrade the system according to the instructions on the page. If the above operation is invalid, it is recommended to go to the nearest customer service center for testing and handling. After-sales outlets query: /service.php? sid=3 .

If you need help, please contact customer service at 400-700-6600 for consultation. You can also go back to the factory for examination and treatment. Please call the customer service hotline at 400-700-6600 for details.

Thank you for your concern and support for Nubian products. I wish you a happy life. Thank you.
