1) This phone’s touch works perfect, But touch response will not be fast while playing games. So most of the times you fail in subway surfers.
2) This phone has a slight heating issue, but that is good. inside the back cover you may see a black sheet. That acts as a heatsink. if the heat doesn’t comes out, the processor may lose its ability. so its a brilliant design to bring the heat out to the back cover.
3) the back cover may heat up a little. But no problem.
4) multitasking? no problem, its a android lollipop 5.0 so its very fast while switching between multiple apps.
5) SAR value is 0.29 which is very low. So this phone safe to keep near ear and speak for more hours. maximum allowed SAR value is 1.7. so this is best for long talking peoples.
