after editing when I click either the check or the X to confirm or cancel the app freezes and closes without an error message. I've tried wiping cache/data, uninstalling and reinstalling, factory data reset completely wiping my phone from the settings menu and from my recovery and nothing has worked if anyone has any suggestions would be much appreciated by the way I'm on a galaxy s3 Sprint.
Did the crash occur while you have tried to apply an effect? If so which one and how large is your document (plus layer count)? Could you try to reboot your device and give it a try again. It could be that your device is running low on memory.
