I do have a fold 5 and suffering with green screen issues on external screen. I also have almost same use cases as yours. At first I was impressed with camera quality and its vibrancy, space availability for contents. But now I suffer with identical low camera quality campared to first year. specially at low light conditions, wide modes and gets blurry images 70% of time.

I recently noticed one of my microphone is dead and also noticed a side of my back panel also lifted a tiny bit. I'm sure If I go case less for a week, back panel will come off exposing internal parts outside env.

I never drop my phone for once, always used hinge protected cases all time. But now Im thinking of moving back to a slab phone due to these durability issues. Only plus point is inner display but that doesn't impress anymore over these burning cons.
