My first impressions:
+ Call quality (good, nothing to complain about)
+ 3G / 4G reception good, better as SGS2 (3G) same as for LG G2 (4G).
+ Battery power (Take me with constant use with 4 email accounts, sync. Every 30 min. / Whatsapp / FB) loosely on the day.
+ Camera (For 16: 9 resolution with then only 3MP) good pictures in good light, sufficient for example a photo book.
+ Haptics is good, light and slim nothing creaks, who would notice a yellow or orange takes Original Cover.
+ Price (Despite the absence of photo light and compass)
o Wireless reception performance is average, but acceptable.
o Display resolution still acceptable illumination Show Average.
o working speed is very good, the start behavior of Apps terms of speed does not.
o Windows Phone is sufficient for me in the functional scope and the Appauswahl, but you should inform as transfer passengers already over. (Quick Access / Appangebot)
It is somewhere between 4 and 5 star ...... I'll give you 5 due to the price-performance ratio.
Buy recommendation!
