This will disable Snapchat to access your internal storage, which will result in Snapchat being unable to detect screenshots.
You will still need to give Snapchat the storage permission.
These commands may need to be run as root.

In contrast to disabling the storage permission, using AppOps Snapchat will think it has access but given an empty folder structure on read.
The app will still work as it should, you only can't see camera photos taken in any other app in the Snapchat camera roll.
Sharing images from another app to Snapchat is still possible.

This is tested to work on LineageOS 17.1. It will work on any ROM with AppOps support.

To undo this, run the same commands, but replace ignore with default.

I am new to this. Where should I paste those lines?

if you're on a custom rom, connect phone to pc, turn on usb debugging, open cmd after downloading adb, type adb shell, and paste these one by one

Worked fine til Android 12. With the Android 13 update this isnt working anymore. Tested with rooted (OP 8T w/ Pixel Experience plus) and non-rooted Phones (Samsung Galaxy S22 Stock ROM).
