This phone is really good. I have used this phone and I have not found any issues. It has 2gb ram and is powered with 1.2 ghz cortex a53 processor. No issues with performance. I played high end games and it runs soomthly with some minor frame drops.
Battery backup is also very good. And samsung has changed their UI so no more fear of laging. Camera quality is superb and also the flash quality. Front camera is also good. And there is also a front flash so it is very good for selfie lovers. Overall according to the price its a good phone.
