7. Circle on the 3.5mm jack
Sometimes we may notice that the end of the 3.5mm jack may have one, 2 or 3 metal rings. Their main purpose is to separate electrical impulses received from the devices to transmit information. For example, a strip in the headphone jack means it can only provide a mono audio signal, which means that both sides of the earphone receive exactly the same information. The two stripes are able to separate 2 signals and transmit stereo. This makes your left and right headphones sound a bit different. Three stripes are commonly found in devices that support microphones.
8. The icon of opening the lid on cosmetics

After a few moments, you’ll receive a pop-up message, instructing how to undo the previous action.
If this feature does not work, go to “Settings”, find “Accessibility” and “Shake to Undo”
