I have long thought this giant smartphone in size "chocolate bar" to buy. I have not regretted the purchase - a great piece of art! The battery lasts now after a few charging cycles loose 4 days (when used correctly). Compared to my previous LG G2 smartphone Sony holds an extra day (with the same user behavior). The protective flap that are constantly open loading must remain always closed to me because I'm using a magnetic charging cable - very convenient. Only as a Navi in the car I had to rethink there because the charging plug is not plugged as usual at the bottom, special on the left side. But I bought a nano USB extension so that my charger cable from the cigarette lighter is now long enough. GPS signal very strongly - satellite is found quickly - as well as the reception quality. Here I have compared with my LG G2 better reception. The reception strength is stable. Important voice quality: I understand my interlocutor very well and my opponent understands me very well. The communication problems were well resolved by the previous update - with me no communication problems. The camera takes exceptional pictures. Since I am not so spoiled by LG G2. All in all a very good smartphone. No stuttering, long battery life, bright screen and very good feel. I use a bulletproof glass slide and Terrapinhülle in black (here can also solenoid cables be used). Only the size of the smartphone is used to, but to get over - it fits nicely in my pocket
