If you see a button labeled "uninstall updates", that's a system app which you cannot remove without root powers. User-installed apps never have that "uninstall updates" button, for a simple technical reason:
- a "system app" has its original
.apk file installed on the
/system partition, which is mounted read-only. If it receives an update, it thus cannot simply replace its original
.apk – so the update gets placed on the
/data partition (along with the user-installed apps).
- a user-installed app gets installed straight on
/data – so if there's an update, it replaces the originally installed
Hence, by the simple existence of a button labeled "uninstall updates" you can tell that's a system app. You then can push that button: after uninstalling updates, in most cases it changes its lable to "disable". Push that button again, and the app is "disabled" – i.e. doesn't turn up in your app drawer, on your homescreen, or anywhere else except for Settings › Apps (where you could re-enable it when needed). That's the closest you can come to uninstalling without rooting your device.
