I own this mobile approximately 2 years ago, when it was newly launched.I was highly impressed by the specifications of this phone while researching about various mobile online, soon I without giving a second thought I bought it from the market as it was affordable in comparison to other android devices loaded with the same features what it has.
After using it around 8-9 months it start getting heating problems when used continuous also the battery backup was depreciating, In my case battery was swollen, I soon replaced a new battery and purchased a new one, but after using it a while same problem continues, I finally sold it on OLX with a new battery in half the price I bought it for.
I want to mention here I dont face any lagging or hanging problem with this phone, it is user friendly also, display is crisp and screen resolution is quite good.
Phone is good for short run.
