Issue with Main Screen Functionality After One UI 7.0 Update on Samsung Fold 4

[EMonteloyola]

I recently upgraded my Galaxy Z Fold 4 to One UI 7.0, and since the update, I have encountered a critical issue with the main foldable screen.

Upon unfolding the device, a brief static sound is emitted, followed by the main screen turning completely black. After this occurs, even switching back to the front (cover) screen does not restore functionality. The device becomes unresponsive, and I am only able to regain access by performing a forced restart using the Power + Volume Down button. I had tried to factory reset my phone and still I have the same issue. 

This issue has significantly impacted the usability of the device, and I kindly request your immediate assistance in resolving this matter.

I have the same issue, what I can do now if I want to use the main screen is, lock the cover screen first, then open the main screen, then the main screen can be used

This it's literally my story....

Had long calls with samsung and my network provider...

Both simply claiming that the phone is out of. Warranty, and needs a full screen replacement...

Total joke
