Default Camera apps & HDR not working on 4.4.x

I know the HDR+ function is not supported for our devices but the HDR function on other camera apps I've downloaded doesn't works either on 4.4.x ROMS and the stock camera app it's not so good, doesn't have many options. I love aokp, cyanogen, omni but I've been sticking to TouchWiz ROMS just because I love to take pictures and it supports HDR and other options from its stock camera app and many other camera apps out there. Some good camera apps don't even open at all in these ROMS. Is this kernel related or something? Can I work around this to stick to 4.4.x ROMS?
