Access Telephoto lens on Samsung Galaxy s10 series

[Anonymous]

I really appreciate that Open Camera lets you use the wide angle lens, but the telephoto lens isn't an option right

Unfortunately this is down to the device itself, it suggests Samsung have only made the wide angle lens available to third party applications, and not the telephoto lens.

Is this also valid for custom ROMs as LineageOS? Do they have access to Tele lens?
Edit: Yes, access to all cams is possible!

Suggestion: Would be great to have a (single) zoom, automaticall select the right lens.
So starting from 0.7 ..... 8 using <1.0 Wide, >=2 Tele

A quick search brought me here:

Samsung whitelisted these package names for the telephoto access:
com.sec.android.app.camera
com.sec.factory.camera
com.sec.android.app.camera.shootingmode.social
com.sec.factory.cameralyzer
com.samsung.android.bio.face.service
com.samsung.android.biometrics.service
com.samsung.android.server.iris
com.samsung.android.aremoji
com.samsung.android.ruler
com.samsung.android.scan3d

Most GCam mods for Samsung either have com.samsung.android.ruler or com.samsung.android.scan3d as package name to circumevent the restriction because those apps are not system ones. I wonder if the telephoto lens will be discovered if a custom Open Camera apk will be build with either of those package names.
