Today I accidently did let drop my Clix2 and it fell about 3 meters down on a hard floor.
The display did half open and I deceided to fully open it (Thx for the great tutorial m2tt8).
After replacing the front again, I recognized that the micro buttons didn't really work fine anymore. After opening and mounting it like 10 times I did not really see a big success. The clicking did still not work smooth like it was at the first day I received it. After playing a bit around, I recognized that you have to slighly lift all the 4 edges with your finger nail (one by one) and push the front a bit to the left and right. In the end, this worked for me very well to get it back to a smooth clicky operation.
I just thought to post this, in case someone encounters a similar problem.
By the way, I am still very surprised the plastic didnt brake, this bugger seems more robust than I thought it would be
