In this case, an Apple iOS update seems to have broken At&t's wifi calling. At&t wifi calling abruptly stopped working with 9.3.2 and when I contacted At&t about it, their tech suggested I switch off cellular data, switch on wifi calling and reset my iPhone 6: Every single time I want to use wifi calling. Really? Oh, yeah. And then reverse these steps when I leave the bad signal area. Every single time. I'm taking my line to Verizon. My work-issued Verizon iPhone 6 has 80 pct charge in the afternoon while my personal At&t iPhone 6 has 30 pct charge in the afternoon due to the signal strength in the building where I work. When At&t wifi calling was working, it wasn't quite this bad but now that wifi calling is broken, I feel I'm forced to move on.

My wifi calling broke last night and now today I can no longer make or receive calls. The att store said they had numerous people that had the same issue from last night.

Data works. But cellular calls fails. She said everyone that had the problem all said they recently updated their phones.

She also said DO NOT get a new sim as the customers that did switch to new sims ended up with phones that could not receive data or calls.
 
Since downloading 9.3.2 on my iPhone 6s four days ago when an incoming call while I'm in vehicle with Bluetooth it rings on both the phone and the car audio. Never did this until download and its damn annoying. Hope they correct this soon. Three other people I know have the same issue since downloading 9.3.2 several days ago.

I've had this problem on earlier versions of iOS. I think it was an earlier release like 8.something. I even got an advance replacement iPhone 6 because of the bluetooth issues I was having at the time. I would get calls randomly transfer from the car to my earpiece to the phone DURING calls. Apple put me through a lot of hoops trying to solve this, including factory reset and setup as new of my phone. I was also having Apple Watch bluetooth problems. It's interesting that 9.3.2 advertises bluetooth fixes. Apple only mentions iPhone SE in the 9.3.2 release notes but I bet they are fixing wider bluetooth issues and it doesn't surprise me that you're seeing something new.

Back when I was using the car audio and before I was having the issues of sources changing all by themselves, I noticed that when more than one device was ringing it was no big deal because the call would simply stick to whichever device I used to answer it. One thing you might do is simply live with the multiple ringing and see if the call stays where you answer it.

If you still aren't happy, I suggest you open a support incident if this bothers you. Another thing you can do is reset the phone and set up as new WITHOUT doing a restore from iCloud. Of course all your contacts, photos, etc would still come back (depending on how you have iCloud set up) but you would have to reinstall all apps, etc. This means a lot of stuff you might care about won't come back such as text messages and call histories. Apple had me do this because they suspected something in my settings might be interfering with bluetooth. Bluetooth performance and reliability did improve when I did the reset but not enough for my needs which is why I got the advance replacement. I should also mention that things have been better ever since so maybe there really was some sort of hardware issue.

Today I switched to Verizon from At&t and I notice call performance is a LOT better. The audio events that occur at the beginning and end of calls are much more predictable. At&t was good enough for me for several years but recently my group moved to a new office where there is no At&t service. I was going to switch months ago but At&t got wifi calling up and running just as I was about to switch. Last week, when 9.3.2 came out, I lost wifi calling and when At&t support couldn't help me I decided to switch.
 
I tried 9.3.2 for a few days, updated through my PC... No good, laggy, buggy, bad battery life. I did a full dfu restore and setup as new... No bugs, but my battery was just as bad if not worse. Back to 9.3.1 and I'm staying here.
 
Just did my update on my 6s. It's nearly 3am here and the Night Shift mode was on.

Right off the bat I noticed that while Night Shift was still on, the screen was certainly brighter. I checked the warmth setting and it was still set at the (default) midpoint. To obtain the screen appearance to the pre-update level I just pumped the warmth setting ("More Warm") to what I would call the 66% spot.

I haven't read the previous responses here to see if anyone else had this same "issue" post-update.

I have seen that my NightShift sometimes keeps on in the morning (although I set to for 22.00 > 07.00 and I still see a yellowish color around 08.00. Although it's not on. Manually turning it on and off again causes it to switch to normal again (more like a bright white color). It's a bit a different complaint. I have seen this behaviour on the previous version and still in the latest 9.3.2 version on both my iPad mini2 and iPhone 5s. Have you also noticed that?

Overal my experience with 9.3.2 is that it's a fast OS, no lag. Although there is still the delay in response with some third party keyboards showing on my iPad mini2 (especially Swype) if you compare it to the Apple keyboard. This has been an issue since iOS9. This wasn't the case on iOS8.3/8.4 I think.
 
Can anybody else confirm that on iphone 6 9.3.2 is worse than 9.3.1?
I'm still on 9.3.1 and thinking about updating. Saw a lots of post with iphone 6s, but only a few with iphone 6.

iPhone 6 here - updated OTA. No difference I can see between 9.3.1 and 9.3.2.
 
I had an issue on 6s Plus on AT&T. The phone wouldn't go back to LTE after a phone call on 4G (AT&T's HSPA+). Spoke with apple at Genius bar, and she offered to replace the device, which I did. She mentioned to talk to AT&T if issue persists, which it did. At&T replaced SIM and re-registered with the network, but nothing helped. Finally, i rest the phone and set it up as new, and this has fixed the issue for now.
 
Anyone else having trouble with the camera app freezing from time to time? Restarting the app or restarting the phone doesn't seem to help, and the freezing often resolves itself after a couple of hours. This never happened until iOS 9.3.2...

Yes!!!

And it's driving me nuts. Of ALL the times - it froze while filming my daughters piano recital tonight - It showed as recording the whole time - and what it then gave me was two separate video files - the first 20 seconds of the performance - and the picture is frozen its only audio - and then a 2nd video file 6 seconds long showing her bow...

Every few days - the camera app just freezes... yeah it's a huge pain.... I have to kill the app - and then it will work for a few pictures...
