TECH CIRCLE for Samsung Galaxy Z Fold 4 Case Hinge Coverage Protective Case with Built-in Kickstand PC Magnetic All-Inclusive Shockproof Cover for Samsung Galaxy Z Fold 4 5G, Blue

Loved the concept of this case, but the magnet in it caused a malfunction in the phone itself that prevented the use of the inner screen when you opened the phone. The outer screen stayed on and the inner screen stayed black. I thought I broke my phone. Did several hard resets. I did a bunch of internet research. I thought some kind of internal cable came loose. Finally came across some info that said some phose cases can cause this and realized that even those if been using this phone case for a day or 2 now, that I hadn't used the inner screen with it yet. So while open I took the back part of the case off and *boom* magically phone started working properly again. I returned the case to the store the next day.
