I managed to find a thread online which talked about lining the chip with the side of the coil and not the middle.
And also showed about using the back of the PM3 for HF and not the part where it shows to put the card
tested and got a read on each LF and HF
So that helped
and now I know that works, i think that might be whats happening on my phone as well, and im lining it up with the edge of the coil without realising when it works in the bottom corner
