Z Fold 3 screen not changing

[Kitwit95]

Evening all. Had a sudden strange issue with my fold... when I unfold it, it doesn't change from the cover screen to the main screen. The cover screen stays lit and tough-sensitive. I've tried a soft reset and noticed the main screen still works because it lights up during the rest. Its as if the phone isn't recognising that it's transitioning from one position to another so isn't adjusting the screen. Anyone able to help?

I'm not aware of any setting that would do this @Kitwit95 

Try a soft reboot by turning the phone Off and On.

Just to ensure nothing downloaded in causing this please use > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

> https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 

If it continues then you could try a factory reset but I'm not convinced that would help. Back up beforehand however.

A Samsung Experience Store or Samsung Service Centre can help.

It's happening to my zfold 3 too. Did factory reset helped?

Factory reset didn't work. What it turned out to be was my phone case. I have a magnetic pouch on the back for the pen and as soon as I lifted the magnet away it switched screens. I had to do that every time I wanted to switch screens for a while but the issue has completely resolved now

I encountered exact the same problem as you mentioned. The problem just occured yesterday. I am using Fold 3

I am experiencing the same issues and it was not the cause of a magnetic case. Even when out of case it won't transition screens.

A fix for this would be great. I am not sure if it is hardware related or not.

I just encountered the same problem. Have soft rebooted, removed the case, cleared the phone's cache. Nothing worked. Did you get this resolved?

I had this exact issue.  Only the front screen would work and when I opened the phone the inner screen remained dead and the front screen remained on.  For me rebooting the phone with the phone unfolded fixed the issue.
