Cannot switch Wifi on

[Wantonmien]

Hi. 

3 July my Fold 3 had a Samsung update loaded, and since then, in Setting/Connections I have not been able to switch the WiFi on, thus am using data.

My friend who has a Fold 4, has the exactly the same problem, he had the update same day Jul 3, and since then also cannot switch WiFi on, thus seems the Samsung update is the cause.

Have others had same problem ? 

My friend phone is in Samsung Service centre now for several days trying to resolve it, but I live a little too far away to get to a Service center, and could do without leaving my phone for several days ! 

Yes I reset the phone Network settings, but any other way ?

No my phone not dropped or damaged, it was fine before the 3 July update.

No issues for me. Have you tried Wipe Cache Partition?
