I noticed in the last few weeks that if I’d recently opened the AliExpress iOS app (ie. it was backgrounded) my car audio would freak out thinking I was giving it an audio command. Killing the AliExpress app immediately fixed the problem. After seeing it happen more than once I assumed it was something dodgey and uninstalled the app.
I cannot ever imagine installing something like AliExpress as an app.
It's known that some Chinese mobile apps employ this trick to keep the app alive in the background, the rumor is that this way the 'active user' KPI can be better met.
