Oppo phones will turn green when they enter the SMS screen.

Press and hold the power button for more than 10 second, and then try to turn the machine on and off again.

1. It is recommended to uninstall the third-party plug-ins running before the green screen.

2. If the above measures fail, back up important information such as contacts, information and pictures in the mobile phone in time, and try to restore the mobile phone to factory settings.

3. If all the above operations are invalid, or the mobile phone can't continue to be used after the green screen appears, please bring the mobile phone, the invoice for purchasing the mobile phone and the warranty card to the local mobile phone brand after-sales service center for testing.
