What type of Services? And do Signal use our contacts or something private like that for third-parties?
No. Signal doesn't have Google service dependencies. Although, you have other problem here that you probably heard before, using a Samsung phone "de-Googled" won't make you free from Google. You should check if possible to get an Pixel with GrapheneOS.
Signal does have dependencies on Google as they are required to handle push notifications on Android (without constant background usage)
Yeah, there is that. I don't have push notifications on for Signal and actually for any app
Thanks for reply. I know I can't be totally free from Google. I mean de-Googled as the packages and direct services. My phone model is don't compatible with popular Custom ROMs like Graphene, Lineage, Calyx and /e/ etc. And don't want to use unofficial ones. I mind buying a compatible phone or Pixel. Thanks for advice. Goodbye.
