I solved this problem on my phone by completely erasing the device and setting up as a new phone. I had to reinstall iOS 10.0.2 (although now you would probably have to reinstall the updated 10.1).

1. I saved all my contacts and photos through iCloud backup.

2. Erased the phone connected through iTunes on my mac

3. I set it up as a NEW phone.

4. Reinstall and set up everything from scratch [big time pain in the neck].

I initially tried it the other way, "Restore from backup", but that didn't work--kept getting the voicemail glitch that way. Setting up as a new phone did work.

It was kind of a pain, because then I had to reinstall all of my apps and ring tones individually. I also had to set up all of my email accounts, etc., all over again. It was annoying, but I haven't had any issues since doing it that way. Hope this helps.

Your welcome. By the way, when using these forums, click "reply" in the message you are replying to. It looks like you are talking to yourself.

I found the solution after resetting my network settings. I don't touch my phone while eating and avoid potential accident by not taking risks. I don't have a screen protector and have a speck case. Thanks for trying to help by replying.

Hi

Your 3rd issue appears to describe the result of accidental watch face interactions.

Under the current version of watchOS, swiping from edge to edge across the watch face switches between different watch faces that have been added to the collection on your Apple Watch.

If you tend to only use one watch face, you may find it most convenient to remove any others from the collection on your watch, so that accidental swipes across the screen no longer select a different one.

Watch faces can be added back as and when desired, either directly on your watch or via the Watch app on your iPhone:

Many  thanks for the tip!

I've connected the USB headset via an old non-powered Kensington USB 2.0 hub and it now works fine as expected.

When the USB headset is connected via my monitor (which acts as a powered USB hub) it does not work.

But anyway, I now have access to a working headset.

Quick Update:

I was even able to screenshot this issue which makes me think that it is not an hardware issue.

Okay... After trying a lot and leaving it attached to the computer for a while it does work
