There are several reasons why WeChat update 8.0.3 1 is stuck: First, it may be that the current version of WeChat is not compatible with your mobile phone, which leads to the phenomenon that the mobile phone is stuck. It may also be the problem of the mobile phone itself, to see if the memory of the mobile phone is enough. Try to restart the network, or it may be because the network delay caused the WeChat card to die. The current mobile phone cache is insufficient. Because the mobile phone cache is too small, it will get stuck after starting WeChat update.
