Clean up the storage space of WeChat. As a result, all the contacts are gone, but you can see your circle of friends, but you can't send messages to your friends.

This may be because your software for cleaning the space is not perfect. It is recommended to use Tencent mobile phone housekeeper to clean up the space. It has a special one-click optimization function to help you clean up the garbage with one click. But don't worry, it will only clean up the unnecessary data release space in your system and won't delete your important information. In addition, remember to use Tencent Mobile Manager to close the background program when using the mobile phone, which can also effectively improve the speed of the mobile phone.
