I was more then sure that my actions in the Google Play Store (either mobile app or through website) are the only way to trigger installation of some app.
My phone was lying alone and dark for the last hour, I did nothing:
- around Google Play Store website on my PC,
- around any app or phone in general
in the last hour or so. But, when I have just unlocked it, I have found out that to my extreme surprise, it started installation of Microsoft Teams.
This is the first time in my 10+ years Android history that something like that has happened.
Who (or what) beside my can start installation of some app on one of my devices?

permission //How do I find that out? Install PMX from GitHub or Play store, give it permission for adb (read help) and in the search menu, enable deep search and find out from app ops which app has this permission and disable /ignore that permission for that app
