1. Too many programs are running. If you don't set it, many softwares will run by themselves, and too many mobile phone background programs will cause insufficient memory, which will lead to application flashback.

2. Anti-virus software for mobile phones Some mobile phone software contains malicious code, which will be intercepted by anti-virus software and cannot enter normally. You should download high-security games through the green download platform or use the software store.

3. There is too much garbage in the cache. Usually, in the process of using software, some junk files will be generated. If the mobile phone is not cleaned for a long time, it will become more and more stuck and will flash back. Go to Settings-Applications-All, find the problematic application and clear the data or cache.

4, network speed problems Some software needs a stable network, using a 2G/3G network, which is easy to cause flashback. It is recommended to log in with WiFi.
