Before the beginning I just want to say that I love GrapheneOS.
(in my opinion) Some features are missing (not something related to privacy or security but only convenience)
"Double tape on power button" to activate camera, I don't really care about having a shortcut for the camera. Maybe if we could personalize this shortcut (I love using double tape to activate the flashlight, it's so convenient)
Being able to schedule charging "I want my phone to be at 100% at 9 A.M." So the battery cycles can be respected (I don't know if it's possible but I already seen this option so I hope)
Sorry for mistakes, English isn't my first language
