Does what it claims. (Dev: bug inside) – Doctor OLED X Review

This app is a good screen tester. Don’t expect it to balance your checkbook - its a screen tester. It does that fine. Developer: the button for “OLED & App Info” leads to a text display that’s both editable and a user trap. You can’t back out of it, apparently. Requires a force quit if you click anywhere and enter edit mode as the Exit button disappears in edit mode.
