You asked for anything others avoid, not for how feasible it would be for any given user to avoid them .
I’m not entirely immune against peer pressure either (have to get rid of Discord still).
At least the official Facebook App is known to wreak all kinds of havoc on the Fairphone 2 … alternatives were discussed e.g. here …
From the build of the phone it is obvious Fairphone really put some thought into how to make the phone more reliable while keeping it modular.
But as I said it’s new. Some issues are popping up here already, as can be expected with any new phone, but reliability can only be judged over time.
In my opinion the Fairphone 3 (and perhaps Fairphone overall) will stand or fall by whether they are able to get phones and modules of consistent quality out of the factory.
That pretty clearly wasn’t the case with the Fairphone 2 and its modules, but whether they are able to correct that with the Fairphone 3 and its modules still has to be seen, it’s much too early to assess that.
But you’re right. I would suspect a big player like Vodafone to have a good, deep look into a product they would like to promote to in turn promote a positive image for their own brand with it.
So there’s still hope .
