Permissions worth questioning
Accessibility service
Designed to help people with disabilities. It can read what is on screen and perform taps, which is why malware abuses it. Only grant it to apps that clearly need it.
SMS and call log
Can read one-time passwords and message content. Few apps need this.
Device administrator
Makes an app hard to uninstall. Legitimate for work profiles and anti-theft, suspicious in most other cases.
Display over other apps
Used by chat bubbles, but also by overlay attacks that draw fake screens on top of real apps.
Install unknown apps
Allows an app to install other apps. Keep this off for everything except a source you trust.
Full app list (QUERY_ALL_PACKAGES)
Lets an app see everything installed. A security app needs it to scan. Most other apps do not.
How to review
Open Settings, then Privacy, then Permission manager (the path varies by phone) and check each sensitive permission.
How we use permissions
Psylinks AV asks for permissions only when you turn on a feature that needs one, and explains each one in its privacy policy.
Frequently asked questions
Should I deny all permissions?
No. Deny the ones an app does not clearly need. Many apps still work.
Where is the permission manager?
It is in Settings under Privacy or Security, depending on your phone brand.
