There are several reasons, 1. It should be unbelievable. Just set the description file of the software to be trusted in the general settings of the mobile phone. If it still doesn't open, it means there is something wrong with the software itself. It is recommended to download again through synchrotron. The resources of synchrotron are official and genuine, and can be downloaded for free. 2. It is caused by insufficient memory or low software version.

Please try the following methods to solve the problem: 1. Occasionally, there will be a pop-up prompt that the application is unresponsive: generally, too many applications are opened in the background, which may slow down the system and cause an application unresponsive prompt. It is suggested that in daily use, the applications temporarily unused in the background should be cleaned up in time and enough running memory should be reserved to avoid this situation. 2. When you open the application, a pop-up prompt will appear, but there is no response: this application may have problems during the installation process or be incompatible with the mobile phone system. It is recommended that you upgrade the application to the latest version, or download and install the application again. If it still can't be solved, I suggest you consult the customer service feedback of the application. 3. If there is no response after opening multiple softwares, users are advised to back up the data of the mobile phone, and then restore the mobile phone to the factory value test.
