Dear samsung, please can you explain how a non third party app (messenger) can update itself without having permission to do so? I wont be contacting the app developer because its happening on your product. Why are samsung basically allowing this data breach to happen, im looking at legal advice dependent on what you do about it in this conversation
Messenger as in Google? If so that's how. It doesn't need permission to update via Google Play and really it needs to because updates keep it and your data secure. Either way attach a picture of the app details for the one you mean. It may be possible to disable it completely if you do not use it
That's not a permission setting but a user preference. There's a vast difference and turning it off will put your data at risk if you actually use that app. If you do not, uninstall it. If that option is not available, long hold the icon in the app grid screen and tap the i in the circle. Scroll down the app info and disable it.
