I'm not sure if I'm correct in assuming it is a lens, however has anyone noticed just what awful quality the glass covering the camera on the back of the phone is? The depth sensing camera seems to be a completely different glass to the glass the actual shooting camera.
I have noticed that it picks smudges up so easy, and it is near impossible to clean them off. Even with a fibre cloth, is still leaves marks on there! Also, it's super easy to scratch. I have kept my phone in a case since day one, and it's got multiple hairline scratches on it. A lot of the time people report the HTC One M8 as taking bad pictures, in reality it's because the lens is smudged because when you clean it up it looks better. It seems like HTC have literally just slapped a piece of untreated glass on there, it's worse than a mirror for marks!
