What is the blue dot beside the battery on my Samsung Galaxy — and how do I see which app caused it?

On Galaxy phones running One UI 9 (Android 17), the blue dot beside the battery is a location privacy indicator: it lights up whenever an app accesses your location, in front of you or quietly in the background. It is a built-in feature, not a glitch, and you cannot switch it off — but one tap names the app, and here is how to tighten its permission.

You glance up from a text and a little blue dot you have never seen before is sitting beside the battery, like the phone is trying to tell you something.Short answer: It is. On Galaxy phones running One UI 9 (Android 17), that blue indicator is a location privacy light: it appears whenever an app accesses your location, in front of you or quietly in the background. It is a built-in feature, not a glitch, and you cannot switch it off — but you can tap it to name the app.Why it matters: Samsung already had a green dot for camera and microphone use.

The blue dot extends that same idea to location, which is easier to forget because maps, weather, photos and shopping apps can all ask for it in the background. As One UI 9 expanded to more budget Galaxy phones and tablets in the November 2-8 update round, a lot more people are seeing it for the first time this week.See which app caused it, step by step:1. When the blue dot appears, swipe down to open the Quick Panel.2.

Tap the blue indicator — your phone names the app using your location, for example Maps.3. Ask whether that app needs location right now, only while you use it, or not at all.4. Go to Settings, then Location, then App permissions, pick the app, and choose Allow all the time, Allow only while using the app, Ask every time, or Don’t allow.5.

Also check Settings, then Security and privacy, then ‘Permissions used in the last 24 hours’ to spot repeat offenders you missed live.Pro tip: A dot that stays on is not automatically spying — a family location-sharing app you allowed ‘all the time’ will do exactly that. The mistake is ignoring a name you do not recognize; that one deserves Don’t allow until you know why it wants your location.Ad’s take: This is the kind of privacy feature I actually like — no digging, no jargon, just a little light that says ‘hey, somebody’s using your location.’ Give it a tap instead of a shrug.
