Fix: Samsung Z Fold 3/4 Cover Screen Not Working

Foldable phones have been around for quite some time now. But as far as the folding screens are concerned, the delicate beauty of the technology, be it the folding glass or the plastic screen protector on top of it, remains on the bleeding edge. However, along with a cool trick on the table, it brings some spectacular productivity improvements and future tech that looks straight out of a sci-fi movie. But being on the bleeding edge has its caveats.

Without a doubt, Samsung is the brand to go with if you want the most effective and refined software and hardware experience with a foldable, especially for the Fold series, that doubles as a phone and a tablet. They have been pretty successful in providing a consistent experience to their consumers. But as the UI is still new and there are many moving parts to consider, there may be some issues with the software and hardware that must be dealt with.

So if you are having trouble with a black screen on your Samsung Z Fold 3/4 cover display, here are some fixes to help solve the issue.

Why Is The Samsung Z Fold Cover Screen Not Working?

There may be multiple reasons for that; the software has been total redesigns with the Android 12L release, and Samsung is pushing new updates pretty frequently. This can be caused by a bug or just a glitch. Also, two halves are always moving, it is also possible that any impact may have dislodged something inside, hindering the display signal, or maybe it is broken and needs to be repaired, which would be quite unfortunate. 

Before starting with the fixes, you need to ensure that the device is functional and that the issue is only with the display. If the foldable display is fine, then it will be obvious. But, if that is also not working, look for signs of life, like vibrations on button presses, the phone ringing, or maybe the charging sound. Once that’s done, we can get started with the fixes.
