I have been using this i8262 Samsung Galaxy Core from last one year and I feel it’s not so impressive in term of performance.
Poor battery backup and one more and important things there is no any software update for this i8262 phone, at least they can update OS for better performance.
Otherwise 1 GB ram is enough for performing multitasking simultaneously, Screen quality and touch experience is good. overall good and average phone for android beginner user.
