The comments reveal serious concerns about the level of access certain apps have on Android devices. Specific examples discussed include the QUERY_ALL_PACKAGES permission, which allows apps to see all installed applications, raising questions about privacy and the necessity of such permissions. Users are skeptical of Google's commitment to privacy, particularly in comparison to iOS, which they argue has stronger privacy controls. There are also inquiries about the implications of this access, such as ad targeting and potential monitoring of user behavior. Some users advocate for downloading apps only from reputable sources like F-Droid to mitigate risks.
