Have you checked what’s in it? Every action and touch is logged with all the details. Many people didn’t even guess that such actions could be logged. It’s like super spyware activity; it’s very creepy. “Google is tracking your every touch on any Android device” - is exactly what it does.
I first noticed this issue around 2015, and I have been trying to disable it on every Android device since then. However, it re-enables itself from time to time. I have a few Google accounts, and it must be disabled on each one.
Hm, are there any categories? I didn’t see any, but maybe they’ve added them already. They log whatever they can. Today it’s smartphones and tablets, but tomorrow it could be other devices and other things to be logged and uploaded to Google, like screenshots. The problem is that it’s done behind your back, and many people are unaware of this creepy activity.
By the way, if you did not disable the option to automatically upload all photos to the cloud, then manually taken screenshots are already uploaded. Many people are too busy to find and disable this option. And we’re discussing North Korea here, LOL.
