Disabling Download Manager notifications I have a Pixel 3 XL with Android P, and for the last 3 days, my phone started vibrating almost every hour, at exactly hh:10m, but without showing any notifications.

After much time, I found some sites indicating how to find the origin of the notification: adding a Settings widget to my Home screen, with a Notification log (otherwise I couldn't find the entire log anywhere else). This revealed the cause is Download Manager, informing me at 3:10 AM that I downloaded a file 3 days ago.

Now, I don't remember if I tried uninstalling it from the phone, but the fact is that there is no such app in the Settings -> Apps &amp; notifications menu, so I cannot change its notification settings.

I tried going to the Files app (as some sites mentioned), which states "Notifications: on", but when I select it, the Categories part is empty, so there is nothing to disable.

So, which app is actually emitting the Download Manager notifications, and how can I disable them?
When searching for Download Manager under Settings -> Apps &amp; Notifications you missed listing out the system apps. List them by tapping on the three dots line in the upper right corner and choosing show system apps. Download Manager is a system app and you would find it apps list.

To disable the notifications from that app, tap on that app in the list, then Notifications, and choose an option there that fits your needs.
