Weird noise when cleaning back cover in Xperia Tablet Z

[mars831]

Yesterday I was cleaning my XTab Z back cover and I heard cracking/breaking/unsticking sound 

I made video: https://www.dropbox.com/s/gxfryfkhqxe3fur/MOV_0011.mp4

Do I need to worry about waterproofness and send it on RMA to Sony?

Thanks guys!

You should contact Sony directly

So I have contacted Sony Poland's Tech Support - W-Support and they told me that inside there is double sieded tape which MIGHT unstick after a time. It might be caused for example by heat or anything like that

Are they going to fix it ? remember that if the back pannel its loose it wont be water resistant

It's the same with mine - actually that was the first thing I've noticed when I got it in August and was wondering about the rigidity of the slate as such...

Six months later I can advise that I completely forgot about it since then - tablet sits in a case (that provides necessary rigid support) so would not worry about it at all. Cannot also see any relevance where waterproofness is concerned (do you plan to soak it in water though?).

I also have noticed that weird sound cleaning the back cover. Anyone knows if that is normal?
