OnePlus will be launching three devices this year, and we know about the standard OnePlus 9 and OnePlus 9 Pro. However, there is also a lesser-known device that was previously called the OnePlus 9E or OnePlus Lite. Still, the latest tip suggests that OnePlus is going to launch the OnePlus 9R, which will be the most affordable out of the three devices. Reminds me of the iPhone XR.

There is zero information available on the device aside from a string of code that references the device. Still, considering where it is coming from, credibility is not something that can be doubted.
