Is there any way to fix autofocus after it is set? because having the camera focus before every picture will make the timelapse flicker. Setting the focus to infinity does not work, because in most situations the picture will be out of focus.
Fixed focus option is already available along with infinity, auto-focus, etc though it is not the manual focus I believe you are looking for. The reason is that this cannot be achieved with existing API, see http://stackoverflow.com/questions/23272806/set-camera-focus-at-controlled-fixed-distance-on-android
If you don't see the option, it most likely mean your phone do not supports it.
You can find the fixed focus option under Settings -> Photo -> Focus mode -> Fixed
Since this can't be done by software, looks like the only way to do manual focus on a mobile would be for you to buy an add on zoom/focus lens and attach it to your mobile while using fixed or infinity focus.
I'm also having issues with a Panasonic DMC-CM1 - most of the images are coming up blurry when using 24/7 app. Would love to know if there is anything that can be done to get the app and phone to work - cheers! Mark
