THANK YOU VERY MUCH! I will consider this for the next community meetup of the Austrian Fairphoners.
Indeed I have opened up a phone before I got the FP, which was a Samsung SGH-E250 (it was really green ;)). I broke it during the process though and couldn’t repair it. Repairing a FP is definitely easier! 
Still interesting to see, what was inside this Samsung!
PS.: I see a big black “X” on the Library page. I believe this is not intended?
Also the link to the blog post was dead, I corrected it.
