And they had actual community! Never have I been frequent on any manufacture's discussion forum, but with OnePlus, I was. It was wild to see a manufacturer helping you with rooting their device.
Then I saw the announcement that they'll be merging the bloatware Chinese version of their OS and that was the last day I held my OnePlus phone.
Had they not taken that path, I'd likely have bought at least 3 of their phones since then.
