iOS 11.2.5 Apple Pay Suica Error Flicker in Action (U)

More Japanese readers are posting their Apple Pay Suica experiences with iOS 11.2.5. A consensus is coming into focus. Apple Pay Suica performance has improved and the Suica notification bug is fixed. Unfortunately Apple Pay Suica error flicker, and the occasional full error is a remaining problem for many on iPhone X and is not fixed from iOS 11.2.2. Readers also report the issue is not fixed in iOS 11.3 beta 1.

I captured a video of error flicker. Listen carefully and you can hear the unique error flicker double beep: first the error, then the all clear. The interesting and unique aspect of error flicker is that the transit gates do not close and the louder full error gong sound is absent.

My own experience matches what other readers are reporting. On average 1 in 3 gate transits display error flicker. I have not experienced the issue on non-JR East gates but others are seeing it. That’s good in a way because we can eliminate JR East transit gates as the problem and lob the bug ball back to Apple Park.

Update 1: It looks like iPhone X battery optimization is a possible cause of Apple Pay Suica Express Transit error flicker

Update 2: Apple Pay Suica Express Transit error flicker on iPhone X is also an issue on iOS 11.2.6

Update 3: The iPhone X Suica problem may be a NFC hardware flaw. Details here.
