United States v. Miller

The idea is that in authorizing Google to collect, retain, and use his location information, Chatri lost his legitimate expectation of privacy and therefore his right to complain of a search.

United States v. Miller, this court held that a bank depositor had no reasonable expectation of privacy in canceled checks and deposit slips in his bank's possession." Here's where the court goes on to explain why that doesn't apply here.

Because again, the cell phone has become so indispensable to everyday human life, you don't really have the choice, so they just decided they're just not going to apply it here.

The implications from that being when does the court decide to apply the third-party doctrine and when don't they decide to apply it? And that question hasn't really been answered by this case, so we'll have to wait and see.
