I started using this phone one and a half year before, when I started using the phone the experience was good but later after some months it started getting slower.It even got brick one time.I got it repair several times.The service by the people in service center was good but the phone became damn slow after one year.It heats up very much when I use it while charging.Though it had 2300 mAH batterbut the battery dies in 1 hour.I got my phone downgraded as I was told at the service center that it will increase my phone battery life but no changes were noticed.Some days later my phone phone battery died and when I put it on charging it was not being charged.When I went to lenovo service center they told me that they have to change motherboard of phone to make it work again and the cost of motherboard was around 5000 and by adding some more money I can even buy a new phone.I will never recommend to buy this phone.
