What do you mean the message will come out later and the program will close?

Hello, I'm glad to answer your question.

SMS software crashed. Refresh the mobile phone after the third clearance. If you have backed up data before, or there is no data to be backed up in your mobile phone at present, I suggest you try to enter recovery mode (shut down, press and hold the volume up+power on button to enter recovery mode) to clear all data. Don't restore the data temporarily after booting, and see if the problem can be solved. If it still can't be solved, I suggest you try to brush to the latest development version. Please follow the brushing tutorial.
