What goes well:
- Battery life with me 2-3 days. Less than my non-smart Old, but decent for a smartphone
- Dual SIM works as it should: Switching simply always on both Sims reached when I call contacts that are stored on a SIM card, and it is pre-selected (which had the old phone does not).
- Voice quality is good (speak / understand)
- WiFi works well - I synchronize multiple calendars
- Form Factor: pocket-friendly -> important me and it very well, even better than my old Samsung GT5212
What's not so good:
- I have no reception in some places where I had with the old phone -> not catastrophic, but also not really good
Except for the downer that the reception is not everywhere is as good as the old phone, it is very good.
Addition:
- SD card is now in there, work. I have the maps for offline navigation on.
- Navi goes. The GPS signal needs some time (several minutes) to find, but it's really OK.
