First of all I want to comment on other reviews who have written Camera is not good.Please remove plastic cover of back camera and then check, Camera quality is not bad currently I am using Asus Zenfone 5, but Lenovo Camera Quality is better.
UI is very good, good touch, typing keyboard is good.Calling speaker is good you can hear clear voice on Traffic and Road.No heating problem, Crash and reboot, so just chill and buy this mobile.
Pros:
1.Battery - 10/10 easily lasts for 1.5 days on moderate usage, unique power saving button really does a wonderful job.No need worry when your battery is showing 20%, just switch on the power saving switch the phone will converted to a feature phone.phone. Excellent faster charging feature(2.5 hours)
2.Display: 8/10 vivid, standard & custom modes are available according to your choice.
3.Speaker sound:8/10 single speaker output( only the left speaker is active, right one is for decorative purpose). But overall sound output is very satisfactory.
4.Touch response: 9/10 very nice and fluid, no lag.Charming touch experience.
5.U/I: 7/10 Single lane application.You will get accustomed with it, no big problem.
Free screen guard and back cover. very nice, saved around 250 bucks.
4G Support: 10/10 dual sim 4G support.
8.Browsing experience: 9/10 Very fast and smooth .
9.Gaming experience: 7/10 its a budget device but surprisingly gaming experience wont disappoint you. High end games can be played at ease.
Cons:
Camera:7/10 Rear- average, excellent clarity in day light but in low light condition not up to the mark. Front- decent 5MP shooter, good clarity for selfie lovers.
Lack of UPDATE. 6/10 Unlike Asus, Lenovo is not known to provide regular updates.
Overall: In 8000/- it is a good buy. In these days no phone can give you such a huge battery in this price tag. Highly recommended . Dont think go get it
