ZTE's mobile phone wallpaper was changed to a new one, and then it was automatically changed to the original one. Why is this?

Personally, I think some desktop applications are forced to change wallpaper, such as magic show desktop or ami desktop, and it will be fine after restarting, which is a bit troublesome. I use ZTE BA6 10T model. I found that I was forced to change back after downloading the magic show desktop. Recently, the ami desktop seems to be like this. Personally, I don't want to download the application of automatic wallpaper change such as magic show desktop or ami desktop, otherwise it will be very troublesome. Second, the configuration file of the application that automatically changed wallpaper before was deleted, which led to the noisy operation of changing wallpaper by itself. Therefore, it is suggested that the landlord find out all the desktop configuration files that may change wallpaper and delete them. If not, you have to edit them yourself with the sq editor.
