Ok, guys.. I'm experiencing the same oil mark issue with my white 16GB Samsung Galaxy Tab 10.1 (P7500 - 3G WiFi Version).
Frankly, I'm quite disappointed with Samsung.. This shouldn't be happening to a tablet which costs me nearly USD600. Apart from this issue, the Galaxy Tab 10.1 is marvelous. I enjoy every bit of it except the oil mark.
Sadly.. The refund system is not something, we, Indonesian customers have here.. The tablet itself is not sold by the carriers here in Jakarta, Indonesia. It is sold freely without any contract. Samsung should be responsible for this as the warranty comes officially from Samsung (in Indonesia).
However, curiosity kills the cat. Has anyone here ever brought the Tab 10.1 back directly to Samsung? Has Samsung ever released their official words regarding this matter? Kindly let me know and point me the link to the press release..
Thanks!
