The OnePlus twitter account has been focused on the 6 until now, but the first teaser tweet for the OnePlus 6T just came out. It features the hexagonal “T” logo of the upgraded model and almost certainly hints at the in-display fingerprint reader (which was already officially confirmed).
You can see “Unlock The Future” flash quickly, almost as a subliminal message. This isn’t the first teaser, an ad even showed a glimpse of the phone.

The reply tweets below the teaser are about what you would expect. Someone is posting the 3D renders, others are complaining about the lack a 3.5mm jack and there’s a lot of excitement mixed in as well.
