My Samsung mobile upgraded from Android 6.0 to 7.0. But after that the 24SR seems can't detect from mobile NFC.
It happens only after the 24SR IC locked in read/write. For unlocked the chip by 24SR discovery board hardware, 24SR can detect by mobile again. I tested in Android 4.4,5.0 and 6.0 and all work. So is there any changes in Android 7.0 that cause this problem ? Please advise and thanks.
