For some reason, I need to connect my Samsung phone (Android 8.1) to WiFi locally, no internet required.
However as soon as I send some data through it, the connection suddenly get terminated that I have to reconnect again, even when "no internet" prompt have been clicked "keep connection".
No luck in implementing answers from similar topics as well Stay connected to specific Wifi which has no internet neither forgetting entire other network.
Any suggestion? Or it's simply impossible for non-rooted device?
