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
That explains it. Older android did not have the safeguards modern-day android does. Anyway, don’t sideload shady apps or use old smartphones that are not updated today. These webpage opening things used to happen in the old days, which was annoying.
