It lags alot. Can’t play HD games for more than 1 hr. It heats up and consumes battery like an iPhone. No special features other than a 16 gb internal storage. Late and slow updates. Stock back camera is poor. Stock front cam is laggy. Loudspeaker of grand max is pathetic, barely able to hear anything when surrounded in a crowded or you may say a bit noisy area. No corning gorilla glass and finally all the Samsung phones look similar which is a major let down.
