OnePlus has a different strategy that with their TV from the likes of Apple, Samsung and most major retailers. They are actively leaking news and information about it before it even goes on sale.
Last week CEO Pete Lau tweeted a picture of the remote controller for the TV.
We know that the remote will have a USB-C port, regular Android nav buttons and a Google Assistant button. There also seems to be a touch pad on the controller at the top of the device.
OnePlus may have taken the design from the Siri controller, or at least copied parts, which seems a controversial decision, as most verdicts of the Siri Controller are simply awful.
The OnePlus TV is scheduled to be released this month.
