First of all, an update from my side: I’ve been using the phone mostly either with WiFi or with mobile internet, and I’ve very seldomly had both active. I haven’t had any reboots since several weeks. Even when my WiFi is flaky, as long as it doesn’t switch to mobile internet I don’t seem to get reboots.
Then I just wanted to write a little comment about such issues as people seem to get rather cranky. I’m a professional software developer, and seen my share of bugs and weird crashes. In this case the problem seems to be in a driver of some kind which then causes the OS kernel to panic (i.e. stop working). And the problem seems to be very nondeterministic, happening somewhat randomly.
Such a problem can be very difficult to find.
Perhaps the problem is only happening on some mobile networks. Perhaps with only some specific frequencies. Perhaps there are differences in sim cards. It could be that the developers in that outsourced software company cannot reproduce the problem at all in the networks they are using. It could also easily be that none of those people are experts in driver development, so they have to report the problem further to the chip manufacturer that probably delivered that driver as a binary blob (i.e. without source code). Perhaps the manufacturer doesn’t care much, especially if they are busy pleasing bigger customers. Who knows.
Long story short, there might be very little that Fairphone can do other than keep on hoping that the problem gets fixed by someone else somewhere else. It also might be that they are just ignoring us and not taking the problem seriously, but as we don’t know for sure, I tend to have good faith in the company and believe the former.
I’d also like to have more updates on this (still rather serious) topic, but lets try to stay cool in the meanwhile.
