On my Sony Xperia z1s, I accidentally set a photo editor that is used for cropping photos for wallpapers. Before when a set a picture as lock screen, two applications pop up saying 'Complete Action Using' either This-something-called-app-i-dont-remember and an app for gallery and an 'Always' and 'Just Once' options. I accidentally tapped the app as ALWAYS that i dont want because of the poor quality. Now it is set as my photo cropping editor. Please someone help me and set it back to the normal crop where it has blue lines and grids. It is really frustrating me and I bet other people are annoyed by it too.
