It has a simple, smooth and fast UI.
It has hd display
Good design
Cons
The phone gets slower as more you use, day by day one can feel the change after 6-9 months(according to how one uses the phone)
Its betry backup also get reduced the same way and also it doesnt gets charge fast as fast it should be it takes about 2-2.5 hours atleast with no interuptions or mobile on switched off mode.
It make vedio of only upto 30 minutes and in kitkat somtimes it just crashes before saving vedio so be aware coz u could b left witch no vedio saved. Although there are other devlopment available like cyanogen 12, cyanogen 13 which u can install and its whole way can be found on https://xda-developers.com you can search ur phone there and find many things related to it like even karnels(telo karnel, etc.) as it is a budget phone so a lot of development has been done by the developers world wide.
Its camera is just a lol I mean u can click 2(actually 1.9)mp image wich is good but when utalk about its camera angle its very less
Its difficult to play games on the phone as it get hangs due to it
Its ui also don’t have any aditional feature for which one can say its better then average like it don’t have knok code. The kitkat version is wrost but after u update to 5.0.1. Lolipop it also lacks e feature like multiple android accounts on the same phone
Lenovo also don’t provides bug fixes and monthly security updates for this phone. Its even lolipop version have bugs like if you connect this phone to PC and put it on charge only, after 1-2 seconds the selection doesn’t work and phone do not charge. Overall if you talk about looks of the UI the it good, I like it the most, simple and fast.
conclusion
As the performance is concerned its good its fast as it should be coz of its hardware specification, it can run anything u put on it and will not crash* but the the I hate about this phone is about updates(security pachtes and bug fixes) so if u want it than its a thumbs down.
