view story

http://forum.xda-developers.com – i have been on cm10 quarx since 28.7.12 and updated all nightlies upto 28.8.12 (defy 525/green lens/cm7 froyo kernel). everything is more than perfect but one strange issue regarding bluetooth. my bluetooth is shown as a '?mb525' on windows 7 (means no phone logo seen) but i can pair with pc and transfer files. problem is i cant eastablish bluetooth personal area network service from pc to use my phone as media remote control with gremote.apk or similar programs. also defy is shown as square box on other phones(no logo). my pc recognises other phones very well ie galaxy9003 nokia311 so no (HowTos)
