So the latest and greatest update downloaded to my s21 ultra a short while ago. But now in text messages if I didn't have a picture for the contact it now has the Greek flag. It used to be the outline of a person. Its more colourful now but why has this happened and how do I revert back.
So on the top right corner a green dot will appear when you use an application that is using I.e. Microphone, camera or sensor. It's a great way for you to understand that this is app is using one of the sensors on your device.
