Yesterday I decided to create a second profile on my Pixel 5 with GrapheneOS. The idea was that I would only keep Google Play Services (GPS) and Google Play Store (GPS2) there together with WhatsApp (need it go my kids school) and bank apps, and therefore shut down second profile for most of the time. So, I deleted GPS and GPS2 on the main profile and since then, I have Signal Messaging complaining that it requires GPS. I know I ough to probably be complaining with Signal developers, but before I go down that route I just wanted to reassure myself that this is normal behaviour. Presumably, Signal is complaining that it requires GPS only because its the only way it can notify a user that an update is available? I've done some minimal tests and it seems to be working normally, despite GPS is not installed on the main profile. I guess I could move to SimpleX and ditch Signal but that would be tough given I spent years convincing people to move to Signal 🙂
