In a forum post, OnePlus mentioned that they’ll be releasing the update to the masses in the next quarter. The update is as of now, limited to OnePlus 2, although OnePlus One and X users might also soon receive it. Until then, non-supported handsets will have to use the Jio4GVoice app (previously Jio Join) in order to make high-definition calls over Jio 4G network in India. Their OnePlus 3 flagship phone supports the functionality out-of-the-box though. OnePlus does deserve praise for not leaving out their older devices, whether it’s software or service updates. However, I do wish they release an update for their most popular product, the OnePlus One.
