iPhone message tone notifications inconsistent

Although my problem is definitely solved by turning off BT as b747200 describes above, removing all BT devices did nothing to fix this. I still have Apple Watch in the list b/c you cannot remove it there. Unpairing might help, but haven't tried that yet.

What kind of device was causing your trouble?

I had the same problem as the original poster. My text tone alerts did not work when my phone was locked. Turning off bluetooth did fix the problem. However, I was able to trace the real issue to having my Mac being logged into Messages. When I logged out of Messages on my Mac, then I get text tone alerts on my phone's lock screen with bluetooth enabled. I believe then that there is some issue with Handoff (the bluetooth factor) and Messages on macOS causing the alert to be squelched. I rarely used Messages on my Mac anyway since I generally have my phone, so this is a reasonable workaround for me.

Just finished upgrade to iOS 11.4 and tested 2x SMS which alerted on locked iPhone with BT on (and signed in on Mac). Then got 3 automated SMS login codes from Apple: First one didn't sound but showed up on unlocked iPhone, second one alerted on Apple Watch, third (with Watch in Airplane Mode) did not sound or wake iPhone.

Well, I just turned on Messages in iCloud on iPhone, waited for upload and tested again. All I can say is that SMS alerting is still unreliable. Can't figure out a pattern. Some alert, many don't.

I just activated SMS Forwarding to my Mac mini, tested SMS and got alert on iPhone and Mac. A second test came through to Mac only while using the Mac. A third test alerted on iPhone while Mac was asleep. I

** Messages in iCloud does not seem to be enabled in macOS 10.13.4. Maybe 10.13.5 soon....

I too am having the same no notification tone alert when my phone screen is turned off after now updating to the new iOS 11.4 - I took someone else's advice and turned off the BT in settings and now it works perfectly normal....although now I can't use my watch properly or connect anything that needs BT without taking away the notification tones again. I hope the next update rolls out quickly to fix this - so unfortunate.

We have this problem too, both my wife and I, since installing IOS 11.4 on our iPhone 8's. We've contacted Apple Support, went through the "Game Book" with NO changes to the problem, other then wasting our time.

I also had this problem. Later I found that it was because my iPhone 7 was connected to a Bluetooth speaker. Just turn off Bluetooth or disconnect from that speaker. The problem would be resolved. Hope it helps!

Further update: fixing this for one application (Reminders) seems to have fixed it for all: I was also having problems with in-coming call ring tones. I'm not as sure of this, however: I may have applied one fix that fixed Phone behavior (but neglected to check for that at the time), then a second that fixed Reminders.

IIt’s the same problem Apple had over six years ago and fixed. Tones are only heard over a Bluetooth device if it is connected - not on the iPhone speaker. It started when I updated the OS. I can turn off Bluetooth and get tones but I refuse to use a device without the hands free option Bluetooth provides.

My mom just had this issue.

At first it was just car play that didn't make any WhatsApp notification sound. Then the phone stopped making WhatsApp notification sounds but she was still getting notification sounds on her Apple watch.

We tried deleting WhatsApp and reinstalling but that didn't work.

We tried resetting WhatsApp notification settings but that didn't work.

We checked iPhone notification settings and they were all fine.

We checked she wasn't connected to any Bluetooth other than her Apple watch but that was all normal too.

Then I found this thread but since she uses bluetooth constantly either to connect her iphone to car play or her Apple watch, switching Bluetooth off to fix the bug was not an option.

I thought about checking Do Not Disturb. Her "do not disturb while driving" was set to Manual so that was good and she didn't have "do not disturb" on, nor did she have it scheduled.

Finally I thought since everyone on this thread had issues with not getting notifications when phone was locked that, even though she had do not disturb off and unscheduled, I would try and set the settings under "Silence" within "do not disturb" to "Always" instead of "While iPhone is locked". For good measure we switched "do not disturb" on and then of again.... And hey presto.... It worked, we get notification sounds again!

It was a complete shot in the dark but give it a try it might work for you too.

Good luck!

Try this in my phone it’s workyou see an icone top right side tap it a new window open if hide alert is on p,ease turn it off .....should be worked and solved you prob

Totally fixed my problem! I wondered what the half moons were for! Thanks for he information!

This worked for me. Turn off bluetooth and all my tones worked. Of course now my watch stopped working. Turned it back on and it continues to work. For how long i dont know yet.

OMG! I had do not disturb on somehow. iPhone X is so new to me I guess I thought it was night mode or something. thank you so much!!!!! Face palm moment for sure.

I worked on several possible solutions just today when I lost my sound alerts then it finally came down to just sipp turning bluet off and back on. I’ve been getting text sounds ever since.
