Be wary of stupid apps with practical-sounding names. ScreenClean sounds like an application with intentions of actually being useful, like maybe it removes unused applications from your home screen or maybe it erases glitches and artifacts from damaged videos. Nah. Instead, Cleaner shows videos of cute lil puppies, licking your Android phone's display. To clean it. From the inside. You can put a labrador, a schnauzer, or a bulldog on window detail, or download other versions of ScreenClean with more pups.
