Try unrooting. Tell us what happens.

I personally have rooted the device and even installed xposed and have no problem whatsoever - well except the doomed AOD which is not completely black. Try factory resetting the phone.

What probably happened was that, in addition to rooting the phone, whatever app you used to root it did something else, causing problems. If just unrooting doesn't fix it, back up everything, then reflash the ROM (see [Samsung] How to flash Stock ROM via ODIN.
@Greight: A factory reset doesn't remove root.
