Sometimes there's no sound on notifications after iOS9 update

Awesome! Thanks for clarifying.

So essentially he followed the articles below for those who may want the steps outlined (some overlap occurs in steps between the articles):

How to back up your devices using iCloud or iTunes

Use iTunes to restore your iPhone, iPad, or iPod to factory settings

Restore your device from an iCloud or iTunes backup

restore not working for me

What steps have you taken so far, Siberpro?

Yup, great point - should clarify. I actually fully restored the phone to factory through iTunes, which in the process re-installed 9.0.2. Then I restored from a backup I made right before I wiped the phone. Previously I had just upgraded to 9.0.2 via settings and that didn't fix the issue.

It's been about two hours now and so far everything is working as expected.

Please let us know if this really was the full solution. Performing Settings Reset is a bummer. Performing an entire iPhone Restore is torture. Okay, I know: First World Problems... But I'd probably chuck my $800 phone out the window if I did all this, then press and hold the home button, only to have Siri silently begin listening to me without the little double-ding sound.

mikerisner,

I confirmed with DKMadrid that this was the resolution that he had success with. Please note this process does not entail losing any data.

However, it seems you're describing a slightly different issue with Siri. This thread pertained to not receiving notification sounds in iOS 9. Are you describing a separate issue? Please explain.

Subjectively speaking, I'm pretty sure my phone stays silent for about half of my notifications. Sometimes the screen will light up anyway. Other times it reamins as dark as the speaker stays silent.

About half the time, my alarms will not wake the screen. Thankfully, the sound plays, but I have to wake up the screen to silence the alarm. And I am sure the alarm has JUST started playing when I check. Other times, alarms wake up the screen, I swipe to silence them, and all is well.

About 95% of the time, Siri will not play the little "I'm listening" sound when I press and hold the home button.

I frequently check to ensure my volume is set to the middle and the mute is not engaged. There's no reason for this unpredictability in the iOS sounds.

Perhaps, I'm expanding the complaints in this thread, but I've been noticing this with iOS 9. First on my iPhone 5s, and now on my iPhone 6s Plus. Frankly, it's reducing my confidence in my phone. What day will it be that I'm late for work?

I Am now having a problem with calling out on the phone. WTH Apple. You need to fix theses problems. Still have sound issues and dialing out!

Hll08: To address this specific issue you may be better off starting your own thread in iPhone Hardware. Having difficulty "calling out on the phone" would not necessarily pertain to the issue described in this thread and you'd probably get better traction posting your questions separately.

Best of luck!

So approximately 24 hours after installing 9.0.2 and now my phone's back to random screen-on only notifications. It seemed to work fine for the full day yesterday.

I might be mistaken, but it appears as though the issue is tied to length of time the screen is locked. If I get a message while the screen is on or hasn't been off for very long, the notifications work fine. If it's been 5-10 minutes or longer with the screen off, the notifications seem to stop working. I haven't tested fully, but this is my impression after keeping track of this issue since iOS9 was installed.

bdmorgan72:

This may be trivial, but any chance you have Do Not Disturb turned on? (Settings > Do Not Disturb)

Also, iOS 9 have a newly implemented feature that (to help in saving battery life) will not light up the screen if the iPhone is face down or in your pocket. In other words, if the proximity/ambient light sensor believes there's something obstructing the front screen on the iPhone it would assume it's face down or in a pocket and will not illuminate the screen. Any chance you have something covering the sensors on the top front face of the iPhone (i.e., Case, Screen Protector, etc.)?

If those two things don't apply to you then it may be a bug that you're experiencing.

I have updated to iOS9.1 beta3 the other day, and this problem seems to have disappeared. I tried all versions, including 9.0.1 and 9.0.2, and also 9.1 beta1 and 2, and they all had this issue, but 9.1 beta3 seems to not have it.

So for what it's worth I would guess that this will be fixed in 9.1 when it releases.

Hi all,

I have the same issue on my new iPhone 6s. I didn't really notice it at first (I was busy setting up), but I quickly notice that there was no vibration nor sound on some notifications: most of them work normally, but every now and then (maybe one out of four), there is an issue (mostly on Gmail, WhatsApp and Outlook, as they are the apps I receive the most notifications from). I tried to uninstall these apps, to reset all settings, but still the same (I'm on iOS 9.0.2).

Hopefully a future update will fix this annoying issue, as I don't think that restoring my brand new phone to factory is an "acceptable" solution to this issue.

I Have been having this issue from all versions starting from 9.0 till 9.1 beta 2. What is your feedback on 9.1 beta 3? Has it been fixed? This issue usually begins to happen after a few hours or a day of using. Appreciate if you could share your experience with 9.1 beta 3 after using it for a couple of days.

iOS 9.1 beta 3 fix bug????
