I would really love small REAL Flagship, but without compromise like z5 compact, where they only get 720p instead of at least 1080p, and also less 1Gb of RAM. I mean why cant they just make the specs exactly as Z5 and have people to choose.
That said I'm also a G4 user until... it dies last week for no reason, just keep restarting endlessly, while the phone doing nothing on the table. Strangely enough a friend G4 suffer the exact same problem one month earlier. Since then I bought s6 edge plus for my large screen device and s6 edge as my main device.
Tbh I found no other 5.5inch phone that handles better than G4, it just perfectly designed, it balance so well, I use it one handed 90% of the time, the slight curve really helps more that I thought it would, the leather feels nice and give a decent grip, the only thing that bothers me is when typing its quite a stretch to get to letter "p" and number "0".
G Flex 2 actually handles better but the camera on G4 is much better and I love photography thats why I use G4 and s6 edge.
I really wish in 2016 that some manufacturer could come up with their "mini" flagship but with EXACT same specs as their bigger "real" flagship.
