I had bought a Galaxy Z Fold 4 to try it out before I buy the newest one (Iโm an iPhone user) and it was in like new condition. Randomly I noticed when i opened the phone up the inner screen wasnโt responding to my finger and froze so I closed it up, locked the phone and tried it again. From there the screen went black and hasnโt went back to normal. When itโs cracked a little or phone restarts the screen looks and works perfect just not opened all the way. Repair shop is charging me $400-700 which isnโt worth it. Anyone had this problem?
I seen that some people online stated they changed the flex cable only and it worked. My screen is perfect cracked open, just not all the way open ๐
Yes โ this is a known issue with some Galaxy Z Fold 4 units. The inner foldable screen can fail when partially opened, especially if the hinge or flex cable is stressed. Symptoms like yours โ black screen when unfolded, working fine when slightly cracked or after restart โ often indicate a faulty hinge connection or display flex cable. Many users report repair costs $400โ700, which is expensive because the inner foldable display is proprietary. Unfortunately, thereโs no easy DIY fix, and temporary workarounds (like only using the cover screen) are the only option unless you pay for repair or replacement.
