On my old Android 9 phone, if I plugged in a USB drive and enabled storage, gallery apps would be able to access the photos and I could scroll through them.
On my Pixel 6a with GrapheneOS (Android 13), I can access the USB drive with the file manager and open a single image at a time, but none of the gallery apps (stock, Simple Gallery, Aves Libre) "see" the USB drive.
I gave full access, but even manually adding /storage/xxxx-xxxx in Simple Gallery didn't work. Any ideas?
edit: The old phone lists "otg:/" by default in the "included folders" in Simple Gallery, the new one doesn't show this.
