Conclusion: Stay away! For me also the touch screen error.

Only let the lower keys no longer be operated, then is also the
TouchScreen all dead.

When a colleague who has the same phone, the error was earlier
occurred, now the time has come for me too.

Now, what happens if I give it back, I get a new
Device that gets the error again after half a year?
What if at some point after so and so vielten exchange
Warranty period is exceeded?
How can I be sure that a replacement unit is exempt from the errors?

Just a note to phone my colleague:
He had bought it at the store and wanted it there, for repair, within the framework of
Warranty, deliver. Since the mobile phone at a corner has slight scratches, said
the seller he had probably no warranty on the device, because it
he had fallen down.
What a stupid answer. What did the scratches with this thousandfold
errors that occurred do.

By the way a bit, the camera takes pictures farbverfälschte.
The Kameraabdeckglas is not scratch-resistant.
The battery mounting and cover is ridiculous.

Conclusion: Stay away
