A while ago the CEO of Oneplus confirmed that they were working on the development of their first smart TV, which would be designed to compete directly with Xiaomi and its Mi TV which is highly popular in India.
Since then we had no more news of OnePlus TV so far, since apparently his remote control obtained the agency's certification Bluetooth SIG, since a OnePlus device whose model is RC-001Aas reported GSMArena.
This device is identified as "Remote Control" and would be compatible with Bluetooth 4.2. Recall that the remote controls of Sony Smart TVs with Android TV, have Bluetooth to use the built-in microphone and thus use Google Assistant, what probably replicated on the OnePlus TV remote.
According to the few rumors that have emerged on the internet, the OnePlus TV would have a panel 4K compatible with HDR and would have artificial intelligence. It is expected to be sold exclusively with Amazon in India to enter to compete with the Xiaomi Mi TV which is a success in that market.
