For something like half a year I have only been able to get 2G connection. Sometimes the phone claimed to be on 4G, but the speed was still 2G-like. I thought it was a hardware problem and that the phone was showing first stages of planned obsolescence.
Then - as by divine intervention - in the holidays between Christmas and new year, I suddenly had full 4G connection!
Now I can’t remember the name of the tool used to diagnose hardware issues and how to use it. Is it csd or something?
