Let me ask about: 1. Audio routing bug.  My brother has an iphone 6 and doesn’t 
use earbuds or headphones.  Will this bug effect him?

Subject: My top iOS 9 Bugs

Hi everyone, now that the NDA is lifted, here are some things I think you might 
like to be aware of in iOS 9. 
I am enthusiastic about iOS 9. It is significantly more responsive than its 
predecessor, and there are many new features that I'm sure you'll enjoy. 
Unfortunately, there are also some VoiceOver bugs in iOS 9 that range from 
minor annoyances to potentially critical, depending on how you use your device 
and whether you find yourself affected. Here are just a few that you might like 
to take into consideration before deciding whether to wait for a bug fix 
release before installing iOS 9. Remember that a few days following iOS 9's 
release, it will not be possible to downgrade again, so you should consider the 
upgrade to iOS 9 a one-way trip, and proceed with caution if anything below 
concerns you.
1. Audio routing bug. This is potentially the most significant accessibility 
bug I can recall ever to slip through an iOS release, due to the number of 
people who may be affected. Not everyone will be, and at present, even after 
extensive testing with a range of people owning different devices, I have no 
information about why it affects some users, but not others. It is not device 
specific, for example it is happening to me on my iPhone 6 Plus, but I know 
iPhone 6 Plus users where the problem isn't so severe. Nor does it seem to be 
affected by any setting. If you're lucky, it won't happen to you, but the only 
way I am aware of to determine this is to upgrade.
This bug may affect you when you have earbuds or headphones connected to the 
headphone socket of your iPhone. The primary way the audio routing bug 
manifests itself is when you receive an incoming phone or FaceTime call. You 
can usually hear if you're going to be affected by the bug because your 
ring-tone will fade in and out, rather like the way VOiceOver causes system 
audio to fade in and out when audio ducking is enabled. At this point, if you 
press the power button to silence the ringer and then flick through the screen, 
you will find that not only has VOiceOver become unresponsive, but the entire 
phone has as well.
If you don't press the power button while the phone is ringing, but instead opt 
to flick through the iPHone's screen to locate the Answer button or review 
caller ID information, VoiceOver may not speak at all.
Finally, if you attempt to answer the incoming call with a two-finger 
double-tap, you may not be able to, since VoiceOver has effectively locked up.
The bottom line is that if you have earbuds connected, you may not be able to 
answer a call.
Some people have also reported similar problems answering calls when their 
phone is set to silent.
If you rely on your phone for business or safety, this could be a deal breaker 
in terms of upgrading at this point.
What makes this bug so fascinating is that not only is it completely absent for 
some people, but of those who experience it, not all symptoms are present for 
all users. For example, some people experience the issues I have described when 
they press the power button to mute the ringer, but not when the phone is 
ringing. Others can answer a call by pressing the button on their EarPods, 
while others cannot.
If you upgrade and are affected by this, here are a few things to try.
(A) If you have the more moderate version of this bug, avoid pressing the power 
button when you receive an incoming call.
(B) Turning off audio ducking seems to help a little for some users.
(C) If you can't answer a call with a two-finger double-tap, try pressing the 
button on your EarPods or similar device if you have such a device connected.
(D) If all else fails, you can disconnect any device from the headphone jack, 
answer the call with a two-finger double-tap, then reconnect the device to the 
headphone jack.
(E) Given the critical nature of this bug, if you've upgraded and now find 
yourself afflicted by it, enrol in the iOS beta program so you can receive 
early copies of any fixes Apple is working on. But keep in mind that since you 
will be running beta software, you may well be swapping one set of bugs for 
another.
2. Bluetooth keyboard support unreliable. Sometimes, users may input double 
letters when typing. This is a bug that was introduced in the iOS 8 cycle, and 
can easily be worked around by toggling VoiceOver off and on.
However, a new bug now exists where at times, no text is entered into a field 
at all when VO is active. Toggling VO doesn't help, nor does switching the 
keyboard off and on. The only immediate remedy is to turn Vo off, and keep 
typing without it. If you turn VO back on again, the arrow keys don't work when 
you're trying to navigate your text, and you can't edit it.
3. In the Today view of Notification Center, VO frequently restarts itself when 
flicking through your widgets, and sometimes the phone locks up entirely.
4. It's much less likely you can return to your previous position on screen 
after taking an action. For example, flick through the list of podcasts in 
Downcast. Find a podcast you wish to download. Double-tap, and a shortcut menu 
appears. Choose Download. You should then be able to tap on the screen and 
return to the list where you left off. This worked in previous iOS versions, 
but it doesn't work now, you're returned to near the top of the list. If you're 
in a large news-related podcast where there are dozens of episodes, it takes a 
lot of effort to get back to your place. This also impacts a number of other 
apps including some Twitter clients.
5. Less reliable audio ducking. You may find that if you use VoiceOver while 
listening to audio from another app, audio ducking does not work as well as it 
used to. Some times, it works perfectly, while at others, VoiceOver ducks the 
audio but does not restore the app to its normal level when VO has finished 
speaking. On other occasions, VoiceOver won't duck the audio at all, as if 
audio ducking had been disabled. If VoiceOver has not restored system audio to 
its usual level, sometimes toggling speech off and on again with a three-finger 
double-tap will help. At other times, you may need to toggle VoiceOver 
completely off and on again.
