Thank you for the CameraMX tip. Despite the age of this thread, it was a great help to me, so maybe others will find it, too. MX replaced the default camera app in my first smartphone, a ZTE Blade Sharp (Z971) and its chronic problems with focus, light and color. Camera MX saved it from the bottom of the lake!
I tried Open Camera, too. It improved focus and color, but all pix were dark, even when I adjusted the exposure. CameraMX results look natural. For other devices, Open Camera may be the way to go.
