I am using this phone from last 2 years and for the most part it’s been running well. No lagging between apps switching even in full screen mode i am using 3 gb ram varient still performance of processor is very fast does not get heated up while heavy use. camera quality is also good in daylight and both in front and back but in low light not so satisfactory. No problem in calls, net , wifi or even in Bluetooth device. The look of this phone is Absolutely stunning But no gorilla glass and not scratch resistance . The phone give a premium look in hand. Storage is sufficient 32/64 gb as per user choise with 3/4 gb ram this is one of the best phone under 12k category anyone can go for it .
