Word around the rumor mill suggested Samsung was about to announce a phone with a ridiculous one terabyte of storage built right in, and sure enough: it did.
Samsung announced four different variations of the Galaxy S10 today — the S10e, the S10, the S10+, and the S10 5G. That third one, the S10+, is the one that can come with 1TB of internal storage.
