Top top, flop afterwards.

1. I have participated in the Developer's Preview. It seemed to me quite clear that bugs could come through various updates in the "Developer's Fashion" ... I took into account.

2. The mobile phone I have now for about 2 years, at first I was very happy when it came to service and battery power (battery kept loose by 2 days by). Operation also quite intuitive, not too complicated. Installing and uninstalling apps was a breeze, everything went without problems.

3. After my stay in Brazil came the horror. Making calls was almost impossible. After prolonged use (> 30 min), for example, Whatsapp or Viber is heated the back of the phone and thus the touch panel was now no longer reactive. Nothing worked more (because I wish the good old analog buttons again), you could just solve the problem, in which one out took the battery and the phone rebooted and had to cool down ...

4. When I was back in Germany, there was a problem still. I'm sick of this phone.

5. The only point that I think is good: the camera takes very good photos (but not the front camera).

Conclusion: the actual function of a cell phone, that phone is not satisfied when the touch panel completely out of action is set. I'm going to switch to a different phone.
