I got my phone on the 9th of oct despite it lagging, there hasnt been any major problems like loss of contacts or anything like that.If you are looking for a cheap phone a good camera you should really get this phone.
Battery life is good, can last for 20-22hrs in normal use, in hardcore gaming it last up upto 5-6 hrs, gets heat quickly.
Talking about camera it is good in daylight, will rate it 8/10.
Viewing angles are good from all side side.
It has qualcomm MSM8939 snapdragon 615 processor with 2gb ram.! All over it is good mobile to purchase under 12k!
