Is it buggy on your phone? I got that last week and although I liked it, it started acting weird on my phone. Specifically, half the pics I take with it come out corrupted or something. The file saved can't be reopened. I see the thumbnail in the gallery, but it won't load when I click on it. I get an error message instead. I tried opening it with the stock gallery as well as Gallery 3D and QuickPic.
Oddly enough, mine has started doing that the past few weeks too, but mine was a little lower as I'd say only about 10% of pics came up corrupted (still very annoying tho). I don't think it's the camerazoom fx app b/c the same thing was happening to me with a screenshot app too. I just did the same thing as you, uninstalled / reinstalled both apps. I also unmounted the sdcard, took off the back cover, physically pulled out the sdcard / re-seated it in its socket, and then remounted it. Guess we'll see how the next few weeks goes.
Has yours been working ok so far?
