Tried the ff steps..reset all network settings...turned off wifi location services...etc... pls help naman..ps mobile network is working fine and 9ther devices csn connect to the same network....also i am unable to switch to safe mode to remove cache partition.
Had the same issue, but more severe. Wifi wouldn't toggle on at all as well as the Bluetooth. Eventually, when I tried soft resetting, the phone (Z Fold4) went into bootloop. Had to wait for the battery to drain since soft resetting didn't work anymore and I couldn't get to safe mode. When it did drain, wouldn't charge back up. Brought it to the service center and they had to replace the screen and the battery under warranty. I practically have a brand new fold now. Glad Samsung warranty wasn't a hassle at all.
