@SamsungGulf Eariler I had the same issue without "misuse" and was fixed. And now happens again but still looking for excuse not to fix it under warranty.
@SamsungGulf I'm very frustrated with samsung policy, I repaired my Z flip 3 due to screen hardware issue. And recently the issue came again after 8 months only. But when I sent it to the workshop they rejected repairing because there was a hit on the cover of the phone.
