OnePlus started its existence by hyping up the Android community to a completely irresponsible degree in advance of the release of the OnePlus One. Lucky for them the OPO was a pretty good phone. However, the breakdown of OnePlus’ relationship with Cyanogen Inc. made the OnePlus 2 a less appealing device. It was lacking in a few hardware areas and the software was very barebones. The OnePlus 3 was a clear improvement, but just a few months later OnePlus has given it the boot in favor of the OnePlus 3T.
