I recently switched to Pixel 8a with GrapheneOS and the only feature that I really need is a recording app with some mic adjustment. As it stands most everything I have tried just has too much gain or mic level and causes most recordings above whisper quiet to have a lot of distortion, what’s funny is calls seem to be crystal clear, and the issue only affects audio recordings.
I’m a musician so my use is for recording ideas with piano, guitar, ukulele etc.
Rather than trial and error of moving the phone farther and farther away until I get a decent recording that doesn’t sound distant I would prefer something that just has the ability to set the mic level.
Other than that I am really liking the Graphene experience. It’s a great minimalist OS that is very smooth and it’s nice having all of the extra security features and toggles.
