Sprint is releasing Android Nougat for its model of the HTC 10 today. The update began rolling out to unlocked variants of the handset in the United States back in November. European models started seeing it last month, although it was pulled due to a technical issue and later reintroduced.
The version number is 7.0, which is the same version of Nougat that all variants of the device are receiving, rather than the latest 7.1 version. Combined, those two versions account for just 1.2% of Google Play Android devices, as of February 6. In fact, just 0.3% are on the latest version, as OEMs are still struggling just to push out 7.0, which is at 0.9% almost six months after its release.
The Nougat update for the HTC 10 should come in at around 1.3GB. According to Android Police, it's likely a staged rollout, which means that if you don't see it today, you'll likely see it within a couple of weeks.
