Since buying I have my Z1 Compact in this envelope there. Have by> 5 months, and maybe been taken out. Now I see that the back is severely scratched because since small pieces (dust, granules, sand or what else?) Has been deposited between Smartphone and envelope. I do not know how it is in other cases, here it is certainly the case. Another problem is that many complain that when I turn on speakerphone that you do not understand me. But when I call normal, they listen to me normal. Hard to say what it is. I order now definitely another and try the back somehow to retten.Weil so would I also can completely walk around without a cover, and there would be less scratched.
