WiFi issues since updating to one UI 5.1.1

[imyellowandwhat]

Has anyone been getting issues with their WiFi since updating to One UI 5.1.1?

WiFi connection is not intermittent more often then not it doesn't find any nearby networks and when it eventually does connection only lasts for few moments before disconnecting again.

Phone: Fold 4

Update date: 05/09/23

I have restarted the phone numerous times. Turned on/off Bluetooth. Turned on/off airplane mode....

If anyone knows a fix or can suggest next steps will be much appreciated.

Factory reset was my next step. Will prob now contact samsung direct. Not entirely sure how an update breaks the WiFi. Abit of a joke

Just completed the reset. Nope! Customer service not been much help too

Well my phone has really had it. The screen went black and it only works folded. It turns off if you unfold it. I've got it booked in with samsung 19/09 as I won't post it.

Can't believe I had a perfectly fine phone yesterday, and now today its broken for no reason!

Oh no! Wifi now seems semi reliable. Once it connects it stays connected which is more then I got before.

Is this after updating to new firmware also?

[abster81]

Yes it was! Could be coincidence, could be software!

Just got off with Samsung support. Phone getting picked up for repairs. Samsung pushed another update today. Had hoped that would resolve the issue... Still nothing

Just an update. After the WiFi not identifying any networks, my inner screen (unfolded) stopped working. Only my front screen worked and would pick up WiFi. On the odd occasion I forgot and opened the phone out it would turn off. It would only turn on again when connected to power, then you could remove the cable.

I was so concerned sending it off in the post and being told it was damaged that I booked it into the Oxford Street store. I explained the WiFi issues and the screen and they confirmed it was a common problem and the inner screen needed replacing. I dropped it off last Tuesday and got it back Saturday. It's like a brand new phone! All covered by the manufacturer warranty. Thank you Samsung!
