So personalizing each made again, however, the desire was always less. I usually do this once and not three times.
The unit has been replaced. Now I understand the other party, but I had a buzzing in the speakers. To find a word for it is difficult - it sounded like a vibrating speakers - of course then in "mini-speaker format".
I also often use a telephone to call and do not always have a hands-free while, the noise was very annoying.
In the period of use of a total of about 2 weeks both Lumias me AThe battery life has very shocked. I previously had a 5.7-inch smartphone and since the battery lasted despite phone calls, wifi, photography ... really long (2 days loose).
When Lumia I could almost watch how drained the battery.
And - what surprised me when I read other reviews - the battery of the first unit was very very warm - it was uncomfortable to hold the device in your hand while it was on the charger.
What has surprised me on both devices: I had very often two bars reception. In the office I had the first time often interruptions to the WLAN - which I was not accustomed. And when I put the phone on the desk only to another place. I had no other smartphone.
I had really lost the courage and have now upped the ante money and the HTC One M8 - phone works, the battery lasts - even if I sometimes take a few photos.
If these two defects have not been, I would have been satisfied with the Lumia. But twice problems ?????????? For this, the device is simply not a cheap part.
