Hello. I have a S21FE. I have had no trouble with this phone and it is in great shape. A few days ago I had an update. It was to upgrade to UI-8. Now my phone starts normally and hooks up to my wifi. Then at some point the wifi turns off and cannot be turned back on. All the advanced settings are greyed out and the only way to get back on wifi is to restart the phone. I have cleared the cache and I have tried safe mode. The Samsung tech only offered to direct me to a repair center where I am sure I will be without a phone. The update did this. Do you have any fix for this? By the way my wifi is fine on all of my other devices.
Thank you for your reply. I reset the network settings which reset both the wiwfi and bluetooth. I also cleared the cache. I started in the safe mode and the problem persisted. This S21FE has been a great phone with no problems until the UI8 update. So I backed up the phone onto my computer using smart switch, did it twice to be sure because it does not give you good indications of success, reset the phone to factory settings and then realized that smart switch messed up and all my data was lost. And just to twist the knife, the problem is still there. I am now reconsidering my 15 year+ enthusiasm of Samsung model phones.
