If you aren't able to turn wifi on, more than likely the flex powercable somewhere around the hinge has given up. There may be a tear, but in essence this is a hardware fault, and no software update can fix it.
Soon enough the Bluetooth will also turn off permanently.
I recommend backing up your phone sooner than later.
It's not the phone hardware fault, its the update. Amazingly 1000s of z fold users, including myself, suddenly had a cable fault mysteriously after doing an update??? Come on bro think about what you are saying 🙄
My personal experience was what i described. One day my wifi worked, then it stopped. There wasnt any updates.
When I played around with how much i folded the device, wifi would work.
Eventually the wifi would not turn on, neither would the bluetooth. These are usually symptoms of a poweflex cable issue. Your experience may be different to mine and be of a different issue, but I've also looked everywhere at the time of my issue and this was the most common cited problem. A lot of people wrote getting it fixed by samsung and were diagnosed with powerful cable issue.
