Don't drop your phone!
I clumsily dropped my phone (Fairphone 1) and something broke which made the screen output corrupted. The screen seemed physically OK, but several rows of pixels to the left were black and the whole screen had strange effects and "fuzzyness". I tried opening it up to get to the display cabling (using the official instructions), but I couldn't find anything visibly broken, and adjusting the cables had no effect.
I emailed Fairphone's support, but it turns out they are out of replacements for screens since their supplier no longer makes them. This is pretty bad for a phone that is supposed to be environmentally friendly and repairable, and they claim to have fixed this problem by making the Fairphone 2 modular. I guess with that design they can more easily change manufacturers if needed. In my case, the only thing they could offer me was to use their buy back program, in which they take your old Fairphone back in exchange for getting the Fairphone 2 at a ~100€ discount. They will use it to scavenge for spare parts for other phones.
I have been looking at getting the Fairphone 2, but I did not do that since a) I had a working phone, and b) it was a bit too expensive for me. This situation changed both points, and I decided to go for the offer. Unfortunately their support could not say for how long the offer was in effect, and the Fairphone 2 won't ship until December 16. As a result of this I decided to send my old phone back today, and I'm now without a smart phone for up to two months.
I'm currently using a 30€ dumb phone I've kept as a backup. I think I'll try to live without a smart phone during this time, just as an experiment. It will be interesting to see just how addicted I've become to having a smart phone. If I really need one, I have a really old Android lying around somewhere, and a Nokia N9 :-)
“I noticed that I often used to pull out my phone at the slightest hint of boredom. Now I'm forced to let my mind wander instead, or e.g. observe life around me. Not that bad actually.”
I have noticed this too (In the procedd of divorcing my smart phone). It lessens quickly..
As to your third point. I live quite rural so no mass transit.. For me it was noticing people picking up and checking their devices in the middle of a conversation just because there was the tiniest lul in it.. Which since I have nothing to check on my phone (which seems to now be the expected result) I'm left looking around and wondering what just happened. Quite an odd feeling.. like the other person just suddenly tuned out for 90 seconds.
