If you know, tell me how to clean up insufficient internal storage space in Android phones.

This is simple, just install Tencent Mobile Manager on your phone.

There is a software management function inside, which can be used to manage the software in the mobile phone.

You can delete the software and games on your phone, which can save the memory of your phone.

After deleting them, you can use Tencent Mobile Manager to deeply clean up the junk on your phone.

It can clean up the remnants of mobile phone software and redundant installation packages, etc.
