my best phone so far

What I like:
- The battery is replaceable, which is in terms of conserving resources well
- I find Windows to be extremely easy and intuitive to use
- The display is crystal clear
- LTE. In LTE I would not do without. However, I have changed because of this phone the leader with the best LTE network. Although my previous had a super low LTE deal, but if you look at the coverage times ... The speed was never better than to modem times.
- Outlook, Office, OneNote and OneDrive integration is awesome. I need my dates and data no longer match etc, have everything everywhere

What can be improved:
- In low LTE receiving it often, that cancel telephone lines started. This is supposedly a general technical problem of the radio protocol. Remedied, under "All Settings" >> "mobile and SIM" >> "SIM Settings" >> to activate "profile for wireless connection" as follows: "Telekom 3G". I had initially "Telekom 4G" activated to benefit from the higher voice quality. But "Telekom 3G" is there a stable, where the LTE field strength is so low that has to be changed during a call from 4G to 3G. It has in this setting in traffic yet LTE speed when LTE available.
- The apps use the possibilities of Windows Phone (still) hardly. For example, the apps could show on the tiles already a pre-departure information. Very good solved eg in the weather app from wetteronline.de. However, most tiles are still very static. Probably because they were loveless ported from Android to Windows.
In summary, I'm extremely happy.
