I have encountered some problems

Recently, I found that at some point the IF application will be short-lived, which will cause trouble for my landing and take-off.My device is Android, version 9.0, memory 128G, running memory 6G

Short-lived Caton

Hu chaoMan,
By short lived, I’m assuming you mean it crashes? If so, have you attempted to uninstall and reinstall the app from the Google Play Store? Sometimes that may fix the issue.

This is probably be cause your device memory is low. Please close other apps or restart your device.
