As a convinced iPhone user I bought this little smartphone for use within the family. After a short familiarization on Android system now everything works very well, all functions such as Internet, Whats App and the actual calls are without any complaint. Two small weaknesses there to complain about: the Touchen in the SIM application is not functioning properly (often no reaction on Touchen), also came the device with a Polish configuration, though ordered as a German, a reconfiguring was no problem, but annoying. Both minuses cost but a star!
