I got the part already a 4tel year. Most nervous doing me the attachment of the new mobile phone back. It took a while until I found out the trick and absent in me mitlermweile some anyway for a few fastening lugs of. If you get the part but once ranbekommen correctly even hällts firmly. My tip: first try to press all the corners. This is only possible with pressure, the lid then bulges out slightly at the center upwards. Are the 4 corners in the right place, you take his 3rd hand) and press the curved center of the lid in position (corners but do not release). Oh yes: when inserting the batteries need power and overcome, because it is a little too big matrimonial. The stand is super! I always use the skype or video / TV gawk. And even if I was in the tub web-surfing I plug my index finger through the open stand for additional safety. He is now sadly a bit ausgeleihert but he still does what he should. With all the quality problems also I'd shell out more money for a better execution or what would be great: having to buy replacement backs without the battery again. My battery has at the end of the day on a regular basis more than 50%, even if I still want to watch video Do I need no charger. That the whole phone is now thicker, did not bother me and I have the impression I be able to keep the part better now than when it was still thin.
