Several ways to maintain your phone

1. Frequently clean up mobile phone garbage: The cache garbage generated by mobile phones is very large. If you clean up mobile phone garbage every month, about 2G of mobile phone garbage can be cleaned every time, which is one of the main reasons for our mobile phone freeze.
2. Uninstall mobile applications: some useless applications will drag down the running memory of the mobile phone and affect the running speed of the mobile phone.
3. Regularly clean the mobile phone desktop: Many widgets set on the mobile phone desktop will occupy the running memory of the mobile phone.
4. Restart the phone regularly: Every time the Android phone restarts, it is equivalent to clearing the memory of the phone once, which can speed up the operation of the phone. For users of Android phones, it is recommended to restart the phone once a week or so, so that the phone can be updated regularly.
