Rock Pi 4 with Android 10 / Wifi Issue

Hello,
I installed the Rock Pi 4 with Android 10 (tablet version).
If I switch off the monitor via the Fully Kiosk Browser, the Rock Pi 4 loses the WiFi connection. Can someone tell me something about this?

Greetings,

Hello,
The Rock Pi 4 keeps losing the WiFi connection with Android. Doesn’t anyone really have an idea.
What can I do?

I’m not an android expert but I managed to extended/seriously improved WIFI range/stability on my RockPi4 boards by adding a 2.4GHz /5.8 GHz Antenna + Pigtail bundle:

If you don’t have a UFL connector on your RockPi4 board, a HK module 5B (WIFI/BT 5.0) worked great on my RockPi4C and RockPi4B+:

I have an ufl connector and a external Antenna.
Can i find logs under android?

So I can´t find old logs?
So I must wait, for the problem, when i connected via usb?

Greetings,
