If the application stops running while the phone is in use, you can try the following methods:

1. There are too many programs running in the system, resulting in insufficient running memory. One-click cleaning can solve this problem (restarting the phone can also be used);

2. The phone has too much application data cache. It is recommended to click Desktop--Settings--General--Applications--All--Find the program that has stopped running--Clean up data;

3. It is caused by improper installation location. Go to Settings--Storage--Preferred installation location--Determined by the system (some models do not have the preferred installation location option);

4. Back up the phone data (contacts, text messages, etc.) and restore factory settings.
