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
There seems to be some really old explanation for this but maybe there’s an updated version of this thread: https://stackoverflow.com/questions/19475765/listen-to-own-application-uninstall-event-on-android#22061900
