Backstory: I was looking for a way to disable the low battery notification sound but I could never find an option for that so I just assumed it wasn't possible. Recently after I rebooted my phone. The System UI app, which I had never seen before, popped up. I don't remember what I did to have that show up but I was finally able to set battery notifications to silent.
However I don't know how to get back to the System UI app if I ever have a change of mind. I searched through my phone but I just can't find it. I'm assuming this is a default app that comes with GrapheneOS but it seems to be hidden for some reason?
I took some screenshots of the System UI app menu and the battery sub menu in it but I don't know how to add them to my post. The add an image option just places this: "". I don't know how to use this. If anyone could instruct me on how to upload screenshots that would be helpful for displaying the menus I was looking at. Apologies if this is something that's super obvious on how to use, I don't really post much on forums so I have no idea if this is a common function/utility.
I am on the latest version of GrapheneOS so I'm up to date.
'Battery settings' display no such option for silencing notifications that I see and going into 'App notifications' yields no results. I could be mistaken of course, but right now the only way it seems to get to this setting is to find 'System UI' and I have no idea where that would be. I searched all apps and no luck. Could someone please tell me how to find it?
Thanks.
