I've recently purchased a new Sumsung s9 64gb. After setting it up and downloading apps etc. I went to go check my internal storage to see how much I used it up. It said I had used 20gbs, despite showing in user data that I had only used around 5gb! I checked a family members phone to see if this was some weird glitch only happening to me (She has the same phone) Same problem! Is the used space just being used by the operating system or maybe a logcat issue? Or am I just missing something? All help is appreciated!
