For the past 2 -3 months my WiFi has been unstable (probably since the update just before Android 16). If i unlock my phone or switch between my profile it is unstable . it turns of automatically or fluctuate between ON and OFF . It would take 5 -10 minutes to get it to stable and mobile would overheat while this happens.
note: I use Proton vpn in those secondary profile. I just thought to mention it.
