Grüß dich Tim

i have the same problem, but in my case the two parts are completely torn off.
i now have the turquoise part on my backplate, black part on my table and the spring anywhere around. ^^
mhm... i also contacted the nokia service but they told me the same thing - i should go to the next nokia care point.
(als würde dieses abdeckung sooooooo viel kosten... tzzz)

tried to fix it myself yet but the parts won't hold together.
if i'm feeling good i may go to the nokia care point and listen to what they have to say.
but if you're faster than me (what i expect ^^) then just post here what the care support has to say
