Unfortunately, long-term use, it became clear that the mobile phone had problems with the automatic connection to the hands-free Wider our cars, but then what was the party pooper.
Otherwise, everything runs smoothly. The touch screen responds well. Bugs I have not yet discovered any.
The dual-SIM implementation is super. Each number can be on request, a SIM for outgoing calls assigned.
It's my second smartphone, next to a Nexus5.
Clearly: who wants a lot of surfing or even want to write longer texts, it is not with such a small device with a small resolution happy.
The processing of the device is very good. If you even at the price yet would call weaknesses: The display is only ok and has some problems with the viewing angle stability. Color photos are weak reproduced.
