so i happend to call an emergency number (110) today (nothing seriouse) and for the first call, my network/ connection just vanished.
Like i had 4g+ but i believe some kind of bug happend, which resulted in my phone losing all network connection. (So the call did not connect)
I then quickly restarted my phone and this time it worked.
Not sure if this is a known issue, and i cant provide logs (since i restarted the phone..)
But i thought i should mention it.
(110 is a german emergency number)
