Have the same order with the phone to me this protective film. After I tested the device on the general features out I once attached the film. This was relatively easy. A moment and a steady hand, and she was on it. Only at one corner I had a very small bubble, hardly worth mentioning. But after three days I wanted to call, gave the number, pressed the green fortuitous ... and the phone was black and nothing was more. While you could make a phone call, but the laying gestalltet to be extremely difficult, since the touch panel was nunmal from. Only when the other party hangs up, you could do something again after a short time. Then I have a lot rumexperimntiert, the error but did not find. Since I had the device only a week, we went back also. Monday at 12 clock abgegen the package at the post office, Friday received the return. Top! And? I quote the fault diagnosis:.. "The you specified error is due to the screen protector This can, if not original or in verschutztem or worn condition that cause dysfunction described by you in order to ensure the functioning of the device again, the film was away from us. " The phone now works properly again (in the packet was even used the protector included). Presumably, the film has the sensor activates above the speaker, whereby the device has been faked, I would have it at the ear and therefore the touch panel has been banned. I had, however, the film stuck very exactly. Something must not happen! Otherwise, the film is probably not bad. Was nevertheless a lot of trouble spreads.
