I totally agree with @David_Geneva. Everybody interested in this phone is smart enough to understand that this is an small company trying to grow doing things right.
This topic has weekly-updated information about the number of opened tickets, in which you can see the progress Fairphone support team is doing: Current Support Status (Last update 10.01.18)
I also hope that the screen module’s manufacturer is taking care of this issues to refurbish the malfunctioning screens and Fairphone isn’t losing money with all this.
