Ask whether the permission makes sense
A navigation app may need location, while an unrelated utility may not.
Use limited access where supported
Some operating systems allow selected photos, approximate location or one-time permission.
Review old permissions
Apps you rarely use may still retain access granted months earlier.
Removing permission can affect features
A feature may stop working if the permission it genuinely requires is disabled.
