So I was experimenting with PhotoShop mobile tonight. I have to say this is an excellent app. Of course no one is going to do straight out design on a phone . But this definitely does the trick for your simple file editing. Here is a before and after. Using PhotoShop Mobile, I enhanced the saturation and exposure. See for yourself.
Here is a podcast I just listened with Android PodKast. I think you will like it too
