same problem with losing work here (new droid3, so most recent Android version):
- either phone call or moving to other activity sometimes makes SBM to close and then all work is lost… at least simple oldfashioned “Save” command would help greatly…

Hi, I also use SBP on an Android. Which device do you use? I have the Droid A855. So far, in the past few weeks, I’ve had no problems with saving a file with multiple layers - for me it does not take too long. Albeit it does take a bit longer than a single layer file. I will say that I am very careful about how many processes I have running whilst I am using SBP. I will sometimes end processes to run SBP - just to ensure no problems occur.

I know that importing a photo from the camera onto a layer is a problem if you don’t free up some resources. Saving your work seems to also be affected by lack of resources.
