When I purchased it in May 2015 I was thinking I have got an all-rounder cell phone. But very soon it proved false as the phone started heating like a pancake pan. 2500 mah battery backup was almost 10 hours with decent usage.
After Cyanogen 12 with android lollypop upgrade the heating problem solved. But the phone UI started getting crashed and restarted repeatedly which is very irritating. More ever you can not copy or paste anything in the external memory card. After sending the crash report also several times nothing has been done by the service people.
