If your Galaxy Note 8.0 tablet (or possibly any tablet) makes noises (cracking, etc.) when you simple hold your tablet and move your hand to another spot..I HAVE A FIX!!!
Once I realized I had this problem with my note 8, I began to research the issue on several different forums. I quickly that i was not the only one with this problem. In fact, I was one of several people facing this issue. I constantly read, that many were returning their tablet(s), until they finally found one that did not make this constant, very annoying sound. As I was unable to return my tablet, (I bought mine off of Craigslist) I became bound and determined to solve this issue! What I discovered, is so simple, and so non - complex..I couldn't help but laugh.
I discovered, that just about every single screw behind the back cover of the tablet, was NOT COMPLETELY TIGHTENED!!! I have 2 friends with the same tablet, and the same problem...guess what? This fixed there noise maker too!!
So, if you Galaxy Note 8.0 (or other device) is making cracking, snapping, popping, or creaking noises..open that sucka up and tighten down those loose screws!! (motherboard screws, charging port screws, battery screws, etc.) Once they are nice and tight, have fun snapping the backing of your tablet, back onto the device
