Why does my OPPO phone automatically send text messages? What is the solution (either way)?

If the mobile phone sends SMS automatically, it is recommended to follow the following methods:

1. Replace the SIM card and troubleshoot the SIM card of the mobile phone;

2. Carry out virus detection and anti-virus treatment on the mobile phone;

3. Back up the important data information of the mobile phone and restore the factory settings (Settings-System "More"-Restore the factory settings, please do not check "Clear completely").

After the above investigation, it is still unresolved. It is recommended that you take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling by professional engineers.

Note: This answer is applicable to all models of OPPO.
