Display is good , sharp, nice viewing angles, smooth touch, outdoor visibility is good. Good for movie watching. One thing to note here while it has dragon trail glass my display got scratched.
Battery is also good and will serve you a full day if youre a moderate user. ( I got 4-4.5 hrs of screen on time.) dont forget to calibrate your battery first time you charge this phone.
looks are great. after all its a Chinese apple ; )
good build quality. White version is prone to scratches on the back. though it has dragon trail glass get Get a screen guard and back cover for protection.
flyme UI is meh. not that great. Its good looking and has heavy customization but its like all other chinese UIs. One thing to note here that Google Keyboard has a major bug in it and it frustrates me like anything, when using google keyboard sometimes cursor does not go where we tap on screen.
As far games are concerned major games works good and performance is quite nice for its price. antutu got me 27, 700 score on 64 bit. It heats up when gaming but that does not degrade genuine performance( phones backside goes to around 45°C when gaming after 15 minutes when I checked)
Camera is also nice. lots of modes and customization. But it cannot take 16: 9 photos in native camera app.Natural colors, good white balance good details so camera is good.low light performance is average. Videos quality is also nice.
Call quality is good. 3G works good. never tested 4G.
Dual band WiFi works. OTG works. all my headphones works ( ath-m50x, Panasonic TCM125, Phillips , senheiser hd180) .
Cons-
No option of stock Android. even no custom roms are available.
Moderate heating while gaming ( acceptable level of hearing do me)
bugs in Google keyboard.
hybrid sim slot( cannot use SD card and 2 sim cards)
Less accessories in market for this phone.
Pros-
