Might be a race between API and settings app; Setting app grayed out the switch when API is starting/stopping.

Note that this bug shouldn't block if it's only reproducible on Buri.

I doubt this is device-specific - the builds being tested here are using our own gecko/gaia builds on top of Buri base images.

I can't reproduce this on buri based on 
mozilla-central => changeset: 149342:d71579c316c1
Gaia master     => commit 177fc68d3648666cbc21670cd23f39b4b7bb7515

Can you try it again ?

After OTA update to v1.1 (which blew the previous v1.2 https://bugzilla.mozilla.org/show_bug.cgi?id=926290) I have the same behaviour on my Keon.

It works for me after applied the patch in Bug 917070. 
The wifi and wifi hotspot should not be turned on simultaneously which might lead to wifi driver error.

Sorry for the late response. I'm afraid that I have no idea on cell broadcast messages.
