[Q] STAR N9770 dust problem

view story

http://forum.xda-developers.com – Hi I have an issue with my phone the STAR N9770, there are several small pieces of very small material under the screen glass. I have looked over the xda forums for a solution with no real success. I am wondering if anybody has ever done a teardown of this phone or any other way to get the dust of the screen. Thank you (HowTos)
