So I just got the Android 12 update yesterday. Ever since, my FP4 has been reluctant to use my home WiFi, and will often prefer using the available mobile network (4G/5G).
My home WiFi does have pretty bad coverage in some areas of the house, but when I was on Android 11 the phone would usually stay connected - or at least reconnect pretty quickly if the connected was lost. On Android 12, it seems much more likely to switch over to mobile data. When I open the internet menu (why did the separate WiFi and Mobile Data quick buttons disappear? ugh) it says it is connected to WiFi, but the connected is unable to provide internet. And apparently, all internet traffic is automatically routed via mobile data instead.
I have a smart home setup partially controlled from my phone which requires it to be connected to the local WiFi to work, so this is a very annoying issue. And besides, I only have limited mobile data available, so prefer to use WiFi when at all available.
Any tips or similar experiences?
