We wrote an article earlier explaining why OnePlus 5/5T updates were delayed. That article was published in September, when OnePlus made a forum post informing 5/5T users about the reason behind delayed updates. It took OnePlus 2 more months to finally release 10.0.1, which brings the total delay between 10.0.0 and 10.0.1 to 6 months.

Funnily enough, only OP5 roll-out has begun so far. Don't worry, as soon as they start the roll-out for 5T, the app will get it ASAP. Surely this build would have a thorough changelog, as well as the latest security patches, right? Wrong:

System

Full Screen Gestures

Camera

In 10.0.0, OnePlus removed EIS because it was "currently under optimization", but with 10.0.1 it's finally here. OnePlus kept 5/5T users waiting half a year just to get EIS back, and some other minor improvements. Since the normal software maintenance schedule for stable updates is around 1-2 months, this is very disappointing. The Android security patch in this build is still at September, even though it's November now.
