Thanks for your reply. With previous versions I used, the device got stuck at random not just while charging. Sometimes twice a day. Seems to be better now.Definitely 4.4 is more stable than 4.19.. But 4.19 based ROMs are future.. Very soon 4.4 builds will be discontinued.. We're just waiting for a stable 4.19 build..
@ONeils, yes Sometimes when charging device is stucking.. I know this issue.. If you remove charger after 100%, may be it will no happen.. I'm using it this way, no issue.. I don't have camera issue.. Working fine.. I suggest try a clean flash then check..
