To be fair, both phones were released about 3 years ago and typically speaking, most Android handset makers support their products for about 2-3 years anyway in terms of major updates, so this is par for the course. OnePlus did make good on their promise of supporting 3 major updates, so we can’t say we’re too upset by this news.
In a post on the OnePlus forums, the company writes, “After 3 major updates and more than 3 years of updates, around 60 Closed Beta builds and over 30 Open Beta builds it’s now time to close a chapter and announce the end of OnePlus 6 and 6T official software support.” Keep in mind that this also applies to security updates.
The company made a change in policy when they launched the OnePlus 8 where they said they would give at least four years of security updates along with three years of major updates, but that only applies to the OnePlus 8 and newer, so it looks like both the OnePlus 6 and the 6T will be sitting out on this.
