I've a Xiaomi phone on which twice appeared obviously debug/hello-world notifications (something like "testtest111") from apps I've never seen or installed. Then another time all Xiaomi phones of close relatives started getting these cheap, spammy ads for Android games in the notifications, this time from some obscure system app: had to look up on reddit that there are settings that disable this specific behavior.
The degree to which I don't own my own device is insane.
I gifted my mom a Xiaomi phone a few years ago. Even after removing all the unnecessary apps and permissions, disabling all the privacy invasive settings and replacing the launcher with the stock Android, I was shocked when I checked the PiHole dashboard. The phone was constantly trying to communicate with dozens of different domains and endpoints, even when idle. None of these attempts had any sort of backoff, so they kept retrying every 30 seconds, draining the battery. Ultimately it generated several times more blocked requests than every other device on my network combined.
This was the first and only Xiaomi device I ever bought, no matter how attractive they might seem.
And it's about to change soon. https://keepandroidopen.org/
