So I'm bought a new pixel 7, installed Graphene OS after doing all regular updates. Works perfectly fine. Then had an issue with signal, couldn't register my new pixel, only when I installed the google services. After registration I deleted them, cause I don't want them on my phone. But now Signal seems to go to standby if not used, when I open the app I can see the messages coming in afterwards, on desktop application they get in directly. So of course I also don't get push notifications cause the app isn't working constantly.
I put Signal on no restriction for battery, enabled all notifications and disabled the option for stopping permissions and notifications if app is not used.
What else could I do? Do I really need the google services? Threema works perfectly fine without them..
