iPhone iOS 11.2 SMS text notification

[3460169]

There's been a few variations of threads about this, and an 11-page thread at Apple's own discussion forums.

I have an X that is not in DND mode, Messages notifications settings are proper and individual message thread do not have "Hide Alerts" enabled. Notifications are received, however when the screen is locked and off, the notifications do not wake the screen or play a tone. (Vibrate, also, is off.)

If I turn off bluetooth in the Settings app (not CC), as the Apple thread suggests, notifications once again work as I'd expect with sound played and screen wakeup. If I enable BT once again -- even with no devices connected -- SMS notifications again fail to wake screen or play sound when the phone is locked w/ screen off.

I have tried rebooting several times to no avail and I've failed to identify a fix short of disabling BT. Granted, in my searching, I may have missed it but I don't think so. Thanks!

I don’t have an X so I can’t test personally, but have you toyed with the Attention Aware settings to see if that has an effect?

Thanks, I haven't but I don't think it's a factor. From the Apple Communities thread, older devices are affected too. Also it's just these notifications. Others behave fine (I've tried a bunch). Even iMessages come thru fine. SMS don't. So odd.

I just removed ("Forgot Device") the single BT device my phone "knows", AirPods (first generation), and rebooted the phone again. BT is still switched on but it knows no devices. Strangely, for the moment, SMS notifications are working normally. Going to re-pair AirPods and see if it goes to crap again.

And it still works after a repair of the AirPods. No idea what snafu happened here. The only other variable left to test will be CarPlay on the way home. I do not use "DND While Driving", either, FWIW.

-----UPDATE

As of today it's not working again. Quite maddening.

FYI I looked into this quite a bit more and it seems like it might be a glitch with Handoff, although I tried disabling handoff on phone and iMac and it made no difference so perhaps not directly a handoff issue.

But what I do know is this: Disabling BT on the iPhone fixes the issue and allows screen wakeups and notification sound to come thru for SMS. I couldn't wrap my head around why this is. This morning my X was receiving SMS notifications per normal while on my nightstand, even though I had not disabled BT. It dawned on me that it's not something to due with simply having BT turned on, but the phone is looking for some other place to send those notifications or something like this. And while the phone was on my nightstand there was some separation between the phone and that other device so the notifications showed up on the phone.

The only other Apple device turned on at the time that is also logged into my iCloud account is my 2012 iMac with Sierra (10.12.6), some 25 feet away through some walls.

For the heck of it I turned off Bluetooth on the iMac and sent myself some SMS tests. Lo and behold, they showed up on the iPhone X on the lock screen with appropriate notification sound. I turned BT on the iMac back on, sent more tests, and they showed up on the X quietly (no screen wakeup, no sound). Turned iMac BT off once again, tests again, screen wakeup and sound. WTF? I assume a Handoff glitch and tried turning it off on the iMac but it made no difference. Turned it off on the phone and also no difference. Only turning off BT on one device or the other would elicit the correct behavior.

I intend to be "upgrading" to High Sierra in the next few days and hopefully these gremlins are worked out by virtue of that. Not holding out hope though.
