On a throwaway Samsung Galaxy with American ROM, I installed some Chinese apps. When I uninstall them, the browser opens with a specific “uninstall survey”. How that is possible? Are they exploiting some os weakness or it’s permitted by the apk uninstall API?
The bad actors are:
- sogou keyboard
- Tencent video
Warning - precision guesswork ahead.
In computer programming there’s a concept of a hook - do something before or after an event. It very well might be that “uninstall” event has hooks and one of them is “open this website after it’s done”.
