I have a Google Pixel 8 Pro running GrapheneOS 2025012700. In the stock messaging app, I set custom notification sounds for a few contacts so I can quickly identify who is messaging me.
It has been working fine for months, but 2-3 weeks ago, I stopped hearing the custom notification sounds for contacts when my phone is locked. Instead, the default notification sound plays. However, when my phone is unlocked, I do hear the custom notification sound for a contact when they message me.
I suspect I might have accidentally removed a permission or something. I've reviewed all the app permissions and even reset the app permissions/preferences for all apps, but nothing seems to fix it. Does anyone have any idea what could be going on?
