This happens with Galaxy S3 mini (GT-i8190i) since 1.16, it worked in 1.15:
When trying to take a picture of some text under low light conditions in the preview the picture is very sharp but when actually taking the photo it blurs.
The focus keeps also being lost afterwards in the preview until tapping the display to refocus. I've tried several focus options - auto, macro, manual, fixed but anyway the picture blurs.

Hoping to have a fix for this in next version.
I have the exact same problem on my Nexus 6. I can keep the focus correct when I use Continuous focussing.
Another similar problem that I have noticed with my Nexus 6 is with the preview itself. It blurs when the camera lens is about 2 cm from the text.

I have this issue with a Galaxy S7 running Open Camera version 1.46 ... zooming in to 8x the preview looks fine, but then after the photo is taken it's blurred.
The issue doesn't occur with Footej Camera or A Better Camera, but AZ Camera does the same thing.
Attempting to attach examples.
Here's the footej version.
Ah, just found that enabling the Camera2 API fixes this.
