I have had this phone from 3 weks, its a fair phon.
It has a decent screen, bright enough, ambient sensors do actually work and they determine the brightness in a satisfying way.
Themes give it a nice personal touch, MIUI is fluid, but gets messy sometimes, all the apps are deranged on the screens and there is no app drawer, you can however arrange them in accordance to your will.
Cameras are good, selfies are nice and clear even in low light, just use it somewhat intelligently, place yourself according to the light and you are good to go.
I ordered a nice black back panel, and the phone looks exponientially smarter now, I dont like the white panel, its a bulky phone, has large bezels at the top and bottom, doesnt look bad, but could have been designed more asthetically. Though at this price one cant really complain, one hand operation is a stretch, its a big phone, and is quite heavy too, feels like half a brick in your hand, though if you see that as a positive, it makes the phone sturdy, and in times of grave danger, you can use it like a hammer.
I am a clumsy man, I did let it slip a few times, but like I said, its as sturdy as Thors hammer.
Some of the pre-loaded apps are a pain, the MI music app is pure s*(Google Play Music saves the day), MI gallery is even worse, I have a 32GB card mounted which has around 2000 pictures, and I swear to God, I cant find anything when I need it, I rely google photos now. A file browser is given, but it recognises limited formats, and browsing through the memory is again a pain. Play store crashes a lot, but it gets the job done, if u are persistant enough. Video player however is decent and internet browsing is fun on this. Gaming sometimes is decent, other times it drops frames and I suggest low end games only.
To sum it up
It has all the features one may demand from a smartphone, it is priced genereously, nice camera, decent display, gets your work done.
thank.
