Good Day, recently my S21 has been disconnecting itself from my wifi and when I go to turn it back on the wifi button itself is greyed out and I cannot turn it back on. The only thing I’ve found to work is when I reset my phone it stays on for around 10 minutes before doing it again. I’ve also just factory reset the phone to see if that would help but it’s doing the exact same thing. I’ve done everything google has told me to do when googling solutions. The first photo here is the wifi just loads and loads and loads forever but never actually turns on. When you leave the screen and go back it’s back to the off position and will never turn on. Any help would be appreciated thank you!
Does this only happen with your own home network or when you're in other places?
Have you got Intelligent Wifi switching turned on? If so try turning off Switch to better wifi networks. Not sure if S21 has such a feature or if it will make any difference but it's worth checking.
Could you also try wiping the cache partition
