Why can't my telecom mobile phone receive Fetion SMS? I used to get it.

When the mobile phone is used for a long time, there is more and more garbage and software, which directly affects the running speed and stability of the system. There are also defects in the system itself. The longer it takes, the worse its speed and stability will be.

Try the following methods.

Force data recovery and return to factory settings.

1. Press and hold down the volume down key+power on key at the same time in the power-off state.

2. The guide interface appears, release it, and then enter the restore brush tool.

3. Select to erase the data through the volume up and down and confirm (the volume key is selected up and down, and the power key is confirmed). When the option appears, select Yes.

4. After automatically returning to the menu, click Clear Cache until automatically returning to the main menu.

5. Select Restart and restart.

If it is a Chinese menu. Choosing to clear data and cache separately is the same.
