After using dual SIM cards in vivo?

Hello!

Based on your description, it is recommended that you try the following operations to solve the problem:

1. You can speed up memory clearing and free up space with one click

2. Mobile phone security assistant (iButler) - Clear cache files in mobile phone acceleration

3. Find the program you frequently use in Settings - More Settings - Applications - Installed, and click to enter the program's information interface , choose to clear cache and data

5. You can delete the cache folder in file management. Do not delete except the Android directory and DICM. You can delete other folders

< p>6. If necessary, you can restore factory settings - clear all data to solve the problem. Remember to back up before clearing data.

If you have any questions, you can consult us at any time. Thank you very much for your support of our vivo, and wish you a happy life!
