After prison break, it should be possible to delete the programs that come with the mobile phone system.But it depends on whether the prison break system is good.If the system is not completely broken, it may have some impact.It is recommended to reinstall the perfect prison break version after it comes out.
If you can still access the system, enter cydia and delete the Baidu IME installed previously. This may be caused by incompatible versions. Check to see if there is a new version or use another IME.And I have always used the iPhone. I use iFLYTEK input method.Super easy to use
I also had this situation a few days ago. Long press to see if it can be deleted, or go to the settings to delete If you really can't, download and delete these two programs again
