Since my HTC One already the camera lens was broken a week after the purchase, I looked for a way to repair it myself, because I did not want to send it. So I started looking at various sites for a replacement glass, but could not find one for the One. Now I have ordered this just for trying it. The camera lens is a bit too small for the phone, but still fits on the recess of the lens. Through the guidance which was sent along the new lens could be installed easily and quickly.
I highly recommend this camera glass therefore recommended for the HTC One!
