sim tray cover got broken .it maid with very less quality, and they are telling not cover under warranty.
A full factory reset cleans out old bits that could have been left from the previous OS and apps which could be affecting the performance of your phone. After doing a full factory reset, try to install your apps one by one all the while testing whether you're getting the problems that you posted. If the problem persists even after a full factory reset and that you have determined that it's not one of your apps that's causing the pronlem, then you could safely conclude that the OS update is the problem. That's why I asked if you already did a full factory reset.

the box does not say that the glass of the k4 note is gorilla glass. is there anyone who can confirm this? in any case i placed a screen protector on mine just to be on the safe side. also, the screen protector included in my unit is for the k5 note for some reason, so i bought a third party one to place on my k4 note.
