I got a OnePlus 9 Pro and the NFC performance has been pretty darn good. Better than the Note 20 Ultra. I can get my xSIID to even light (but not read) with a case on it! The blue mark is the best orientation and position I have found to scan my xSIID and NExT. The red mark is the second best location. With the blue mark, the LED isn’t sitting under the phone, so it’s easy to show people the blinky now compared to the Note 20 Ultra where I had to try and tilt the phone up a little to show the blinkie.
Edit: You can also scan the implant with the top edge of the phone as well like the iPhone. Seems to work best in the middle of the top edge if not slightly to the left (away from cameras).
