Why won't my phone detect Bluetooth devices after the iOS 8.4 update?

[iMore Question]

My phone will not detect bluetooth devices after iOS 8.4 update.

I have reset network settings and rebooted. It does not discover any bluetooth device.

What iPhone do you have?

Does the BT icon show when BT is on but not connected?

This happened to me on my iPad 2 when I updated to 8.4. The only fix was to revert to 8.3, which can only be done for a limited amount of time before Apple stops "signing" the files.

Apple is no longer signing 8.3 anymore at the time of this post

Wow. I just installed 8.3 on an iPad at work about an hour ago...

Then I hope I don't need to do that again, as I'd rather not install 8.4 on our iPads until 8.4.1 to fix the bugs!

I have a 4s and after upgrading to 8.3, Wifi was greyed out and Bluetooth just spins. Found that the chip is bad in the phone, direct from a MAC employee's mouth and there is no fix. I upgraded today to 8.4 in hopes that Apple fixed that problem, and no dice. Luckily, I have another 4s with a cracked screen sitting at 8.2 that works. Won't be updating and won't upgrade to another phone until I am ready.
