[Bug] Flight mode broken since 3.1.0?

Turning flight mode on and off again results in a very weird behaviour, mobile data doesn't want to turn back on there is immediate signal (at least icon goes straight to signal strength version) after turning on while it should take some time to reestablish it (at least that used to happen that way). Restarting network from utilities doesn't work, phone is still in this ghost signal state (calling normal numbers results in 'network error', dialling 112 actually kicks it off from it and even mobile data connection resumes after cancelling it). I would not suggest anyone dialling 112 as a workaround, but if flight mode is broken some EU laws in regards to aviation seem to be also if the phone doesn't shut all radios and shows flight mode icon, hopefully they are in fact down and only visual indicators and restart is the issue (above is on jolla C, but issues with network restarts do not seem to be exclusively tied to it in sfos 3)

I can't confirm this for XPERIA X and use the flight mode every night without problems.

I think this might be triggered with short duration flight-mode (seen somewhere a note/hint about leaving the phone for few minutes after choosing flight mode, so might be fine if you leave it for the whole night), still thought it might be useful to bring it up as a lot changed since 3.1.0, restarting network services from utilities no longer is instant (or like 2 seconds max) and does nothing, I do get a new IP now, yay, still it doesn't fix the ghost network mode, 112 call does fix it, but not sure if it's jolla code or the driver blob that kicks the modem into submission, hard to tell, still noted it as an interesting fact, if it is actually controlled by jolla, then there is the fix, but again doubt it. The 3.1.0 network disconnects thread is pretty full of people with xperias (x, xa2) and having issues with reestablishing network connection, which is why I mentioned it's not jolla C specific, but who knows
