Hello folks, I have a serious problem with calling. In some cases, people can't hear me, or very badly, or almost silently. In most cases, my calls get cancelled after some seconds. I can hardly call anyone. Also, people can't reach me because my Jolla does't receive calls. I just receive SMS messages about missed calls first. It looks like I had a very bad signal but if I look at the indicator, it looks good. Or, to be precise, sometimes. Sometimes even the signal indicator gets low and after a restart, it gets suddenly good. Now I have to use a backup phone to be able to call people. It's indeed related to the latest release (220.127.116.11). Before the update, I had to do a factory reset; it might also influence the behaviour a bit.
Any clues what could I do with this problem? I have no idea where to start.
