Before I buy any thing I always read review from other users from different website.so as usual before buy the phone I searched a lot and I found a very funny comment or review someone someone said that phone hits like a portable heater.But after view. the specification of the phone that is an impressive I have to buy this phone. The review I read that phone heatd like a portable heater that was correct. the phone heats like a heater after using the phone for few months I noticed that the battery was decent. Phones are the functions are works normally and smooth on KitKat but after Lenovo updated that Kitkat from lollipop everything gone wrog the battery service is almost half.after lollipop update phone easily hit it even in the standby mode apps frequently freezes camera I become more grainy and hard to use. so I decided to sell this phone and buy a new one that is Lenovo a6000 Plus
