Meizu MX can't find the SMS tag, so it can only lock the screen.

Please solve the problem as follows:

Method 1: Lock the mobile phone screen, then unlock it, press the home button once, and then press the left button five times in a row.

Method 2: Enter * # * # 696 1 # * * on the mobile phone dialing page to bring up the hidden option, open the manual settings, auxiliary functions and all applications, find the Flyme desktop, click Open, and then click Clear Data.
