Have about one year the 3G variant of this smartphone uses and has always been pleased with the performance. Only the expandability of the memory was missing. Now why the purchase of new variant with LTE and microSD slot. The MicroSD has problems from the beginning - a 16GB Class 10 card is not recognized. After some research I found out that tickets which are faster than Class 6 cause problems (can). Had then a 32GB class 6 card with Conrad bought and magnificently funtkioniert since (for about 1 month). To receive: GSM connections have improved, it asked to be on a 1.5-hour train journey a continuous conversation, although there were the old Moto G 3G always dropped calls, but the 3G data connections appear to be worse - I feel I have less frequent and worse UMTS reception. With good development of the network (in cities), I can not tell the difference to its predecessor - yet in the country (the network operator is O2). LTE reception I can not comment because I do not have this option. The camera and all other features is the same as the 3G model. In summary MMN performance: sufficient, "very good" to evaluate the price-performance ratio with: good to very good, the camera quality.
