What should I do if oppo SMS turns green and blue?

For OPPO mobile phones, under normal circumstances, the SMS list displays green SMS by default. But if the message turns blue, it may be because you have turned on "developer mode". In the developer mode, the received SMS will be marked in blue for developers to distinguish when testing the SMS function.

To change the color of SMS from blue to green, you can follow the following steps:

1. Open the phone settings and find "About Phone" or "About Device".

2. In the interface about mobile phone, find the "version number" or "MIUI version number" (the specific name may be different for different mobile phone models).

3. Click this option 7 times to enter the developer option.

4. Go back to the main interface of settings, find and click "Developer Options".

5. In the developer options, find the option of "SMS color" or similar name, and click Enter.

6. Here you can choose to set the SMS color to green, and then exit the setting.

If you can't find the corresponding option, or all the above methods don't work, I suggest you refer to the OPPO mobile phone official website or consult the OPPO customer service for further help.
