Supplement:
1. The downloaded App can't be opened. Sometimes after playing a game, I find that I can't open it. This may be due to system incompatibility or other reasons. Don't delete it in a hurry Try the following methods.
Solution: Settings-Applications-Find the application, clear the cache and try to open it.
2. The application shows that the network cannot be connected.
The reason for this problem may be that the system is unstable (the App version is too low), or that there are too many application caches.
Solution: As above, Set-Apply-Find the application, empty the cache and try to open it. Or, upgrade the application and the problem may be solved.
3. The application cannot be installed on the mobile phone.
When setting up the system, mobile phone manufacturers added a function to prevent users from installing unofficial applications too disorderly, which led to the disorder of the mobile phone system.
Solution: Settings-Security-Allow installation of applications from unknown sources.
4. Error parsing installation file.
This is mostly because there is a problem in downloading the data packet, or the data packet itself has been modified, resulting in packet loss.
Solution: Just download it again from official website and large app stores.
5. The system does not support it.
"The mobile phone system version does not support this application", and all applications have been downloaded. You told me there were limits. What a lie!
Solution: The mobile phone system can only be upgraded by official upgrade or self-brushing.
