Default lagging problems in s4mini(Gt-i9192)

Casual games like temple run oz ,subway surfers even default browser freeze or lagging in Gt-i9192

While temple run , subway surfers and other games are not lagging in mmx bolt a67 which has just 512mb ram and lower cpu, gpu etc .

Why this is happening. May be kernel is responsible for this

Is anyone have solution for this?
