Using OREO 8.1.0 works for me in most cases ( Tagreading/writing GooglePay ..)
But the NFC Signal seems to be weak , so my passport Reader shows no reaction. It worked on an HUAWEI P8 lite.
Maybe there is a problem with NFC extended length issue (depends on HW and Andrid version)
The antenna area is really tiny (Main camera and flash) due to the metal body of the device.
