Thank you very much for your reply.
“I asume with “My app” you mean Litchi?”
Yes, my app means Litchi (v4.24.1-g) app.
Latest updates on both, Litchi and Note 8 (Android 9)
“Litchi does not delete itself.”
Sorry to say so, but Litchi is the ONLY app disapearing every now and then.
“1. Malware on the device” Checked no malware.
“2. Not enough free memory”. Free phone mem: 27 Gb. Free SD card mem: 30 Gb.
“3. Too much apps active in the background”. Never have any app running in the background.
“4. ???” That’s the one I’m looking for the Litchi app is gone every now and then, when I look on my phone in the morning…OMG gone again :-(((…but not every day…
“Check for malware with a virus scanner”. No malware/virus.
“2a. Free up space by uninstalling unused apps”. No unused apps.
“2b. Clear Litchi’s Cache and/or Data” Everything cleared.
" Force Close all apps before starting Litchi". I never use any app while flying and I always disable WiFi
Litchi always works fine while flying, but the disapearing is always when NOT flying.
If you need more information, please let me know.
