Get out of Google is very hard. I've tried on a fresh phone for a few months, without Google account whatsoever. If you are willing to replace Google wallet with some alternative and loose Google maps as well, then OK. But wallet alternatives are PayPal or another couple of US only services. Or go around with piece of plastic like a caveman. And for as good as Organicmaps is, still missing lots of venues and content. Plus many apps I use often are only available on Google store or as apk to manually upgrade and from not really trustable sources..
Caveman here reporting for duty. I will likely have to keep play services on it after installing the xapo app but I will have root so I should be able to remove everything else. And yeah just osmand, for the rare navigation requirement... I can't see myself ditching it completely from desktop but I can stop using mail and calendar, maps on desktop I use maybe 2x a month, translate maybe 5 Yeah, but anyway fuck google.
