1. Man clipst the phone "upside down" so actually the wrong way round in the holder
..... Although this has the consequence that the "pixelate" is turned off, but unfortunately also the function of the "Loud / Quiet" button and the camera
2. You put a thin piece of cloth (eg glasses cloth or folded Zewa) in the entire area below the camera hole
..... Also represents the "pixelate" from, all functions can still be used but unfortunately that phone is no longer fit quite as well in the shell!
UPDATE!
After intensive research, Mr. issued that the app "HTC DOTview" causes this problem in this envelope.
After the DotView function disable meets the envelope now fully its purpose!
CONCLUSION: ..... a little research and future reference necessary, so only 4 stars, an info from seller to Dotview problem in the article description and we could give 5 stars!
