Because 1.2 is going to be finished, should we mark this bug from koi+ to 1.3+? Thanks.

I've spent most of today trying to figure out this bug. I've traced the relevant settings in the SettingsService database and they are properly kept during an update (the b2g process sees the correct value set before the update) however it seems that the settings app is not picking up the values instead reverting to the default ones. I'm still not sure where the problem might lie, maybe a change in behavior somewhere within the SettingsService...

From what I'm seeing this is not a regression caused by the update, it happens even between reboots without updating the phone. When I enabled wifi tethering and then restart the phone the WifiWorker picks up the correct value of the 'tethering.wifi.enabled' preference (i.e. true) but somehow some other piece of code sets it to 'false' afterwards. I can see the call to the SettingsManager resetting 'tethering.wifi.enabled' to false but I haven't yet pinpointed where this is happening.

In the light of this I would suggest re-evaluating the koi+ status of this bug since I'm now pretty sure it was already present in 1.1 and thus is not a regression (I can reproduce it on 1.1 by just rebooting the phone w/o updating).

Fair enough, that sounds reasonable. Moving to blocking-.

We're definitely too late for fixing this one, closing.
