KitKat is old, but not ancient. The issue could be due to some apps conflicting with others, but it could also be related to glitchy firmware or hardware from the manufacturer. It can be hard to troubleshoot this kind of thing -- it would involve uninstalling apps one at a time to see if the problem goes away.
If it ultimately has to do with the firmware or hardware, then there's probably nothing you can do, since I suspect support from the manufacturer will be minimal, if any.
