It sounds like your phone has turned on accessibility settings on it’s own. It could be randomly, or your touchscreen could have a defect called “ghosting”. Either way, go to settings and depending on what iOS the device is on scroll around under accessibility and turn off whatever settings you don’t want on to return the screen to normal. Alternatively, restore will reset it back to defaults if your data is backed up.
