My FP2 from February 2016 works fine too 
.
It has cover number 4 because the first three split, it has very rare reboots and I was really furious, when the phone was stuck in the Bootloop after the Marhmallow Update for the second time. (The problem with the update when the Google App was disabled wasn’t Fairphone’s fault.)
BUT so far, my FP2 hasn’t let me down. No problems in daily usage.
