Awesome painting app. You have layers, different brushes and even selection. It recently has this problem where it crashes the second you try to edit your work, thus rendering the app useless. Ive found three somewhat solutions. 1) restart your device 2) go on ibis paint faq to find out how to save your vector files, then delete and reinstall the app. 3) clear some of your storage These keep the problem away for a while, but there are chances that the problem may come back. Permanently keeping the problem away is up to the admin now. Please fix!
