Hi I have been using the device for 2 days now.First of all the design and build quality is good. Tho the back is not metalic, its easy to hold and use. The look is premium and ths 5.99 screen is easy to use with one hand.The user interface is smooth. I havnt felt any lag in videos, gaming or other areas.But some high end games are not good at hogh resolutions. But that is ok, just reduce the graphics.Face unlock and finger print sensors are fast. And I fingere print sensors can do multi functions such as launch apps, click photos etc.Network speed is great. I havnt felt any buffering in yotube.Camera quality is good, back cam is owsome, with dual cam ( 13+ 2) , portait modes are better, bit not the best. I have posted some pics taken from its cam here.Selfie camera is not bad, bit not the best. But at this price, its ok.Device doesnt heatup much, but while running pubg it heated a bit.Battery is a giant. It gave me 9.32 hours of video time. And for regular use its really useful.Only problem I faced is the lack of speed charging and the protective glass provided by them is not good.Apart from this everything is fine.One last thing, speaker is great both in indoor and out door.THE DISPLAY gave me the best result amoung my other phones at this price range. Its superrr Bright. Even at noon you can easily see your screen.It has a build in screen recorder, so you dont have to install a third party app for recording.There is an option by which you can record any calls just by holding your finger print scanner for 10 sec.Thats all guys. Thank you
