Your problem is exactly like my problem.
I spoke with an engineer technicians Mobile!
Nfc and the rest of your old device and then he say firmware update, or flash custom kernel looking into the firmware itself could have some!
Or wait for Sony to be updated!
So tell me, but also my previous version was 4.3!
i probably bug in rom!!!
I think it's not bad, we reported Sony or Mr. @DooMLoRD
