MI10 performs admirably
Works through case
Antenna seems to be nearly same as all cameras but on the other side, maybe a bit lower.

Updated and linked back to your comment, Thanks
PS
Any additional info added to your post could help out others ( ie, approximate locaton of the NFC antenna, reads through case etc )
Xiaomi MI 8 works great with my NeXT, antenna seems to be in the same place as the fingerprint reader (located in the back of the device)

Samsung Galaxy S10e can be finicky with the xNT while a case is on, but works great without one
Wanted to update my previous comment stating the ulefone armoire 3 and 4 worked and the best location and orientation is having the chip vertical up and below the camera by about an inch. It seems all ulefone’s I’ve experienced so far read best at the top 1/4 of the phone. I was also going to ask if anyone with a pixel 4a could chime in as I’m thinking about upgrading my phone as it’s quite a bit old now.

Thanks for that, I have updated the info…even though I hated spelling Armour 
incorrectly 
I’ve updated my comment to follow your spelling conventions now onto hoping someone with the phone I’m looking at also has an implant and posts that it works. Otherwise this dude is masking up and bribing an att employee so I can run around the store testing every phone and taking notes like a madman for the forum

I get best results with my Samsung S9 when lining the chip up with these two lines on the back of the phone - conveniently, that lets you use your index metacarpal against the edge of the device as a reference if you’ve got the chip nearby.

Getting the weirdest result with my phone / case combination
iPhone XR
Otter box defender pro
(A plastic inner frame with a silicone outer cover)
My nfc chips aren’t reading with the silicone cover on, but if I take it off and leave the inner plastic frame it reads easily
I know… your going to say the silicone is adding too much distance and absorbing the rf right?
Well my Xsiid lights up great thru the silicone
It’s like it’s not blocking it, more like scrambling it a bit
I use to keep my iPhone X naked but recently added a leather case. Makes the orientation I have to read my xNT completely different. Possibly unrelated but
Here’s an example
Not really a complaint, it’s just weird is all

Blackviews S U C K for NFC performance. Can’t get any read on my Flex One at all. Currently exploring a coil to boost signal.

Sony Xperia XA1 Plus works perfectly with the HF side of the NExT.
While I tend to center the NFC Forum logo for regular tags, the best performance with x-series implants seem to be achieved if you go above the NFC Forum logo, around the same level as the LED.
You’ll want to make sure that x-series chip will end up being vertical to ensure good coupling, which means that it will look something like this:
(Only tested without a case.)

Great post, very informative, I have just updated the wiki and linked it back to your post 
You can add the Google Pixel 4a to the list too, it reads very well. The best orientation I’ve found is the tag vertical, just below the finger print reader. I get super consistent reads and writes with a thicker case, and it even lights my xSIID super bright.
At least with a spigen Tough Armor case, this was the only orientation I found that really works, but it’s effective.
