Samsung mobile qq forwarding is slow.

According to your description, I suggest you:

1. Turn the machine back on and try to turn it on (it is recommended to connect with WALN).

2. Try to reinstall QQ after uninstalling it.

3. Try to change to another version.

4. If other third-party software can be used normally, only this software can't have compatibility problems with the mobile phone system.

4. Update the mobile phone system version and then try to install it.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ), restore the factory settings (enter the phone settings-reset-restore the factory settings) or send the phone to the nearest Samsung service center for testing and further processing.
