after added account fb, take picture, press (...) u can upload to fb already.
official windows phone 8 fb app sometimes doesnt work well.. got many complaints all over internet dy..
usually, i browse fb using facebook JDB apps, (this one for browsing only, cant upload pic, but can play videos)
and if i need to surf more, i just use internet explorer to browse fb.. (but cant play videos)
basically for facebook alone, i use three method to access.
-native fb in phone (add fb account) for upload picture, status, and check in, and browse abit
-facebook jdb for normal browse
-internet explorer for complete browse, except cant view videos, (normally i copy the video link, and open new tab, www.facebook, i change to touch.facebook)
yea after adding fb in accounts, i can share to fb from the gallery itself. but when i go fb to see the picture, the image resolution become very bad and blur.
How to upload my picture to fb in ori resolution?? yea the fb app is abit cacat when comes to photo, even check-in oso don work wan sometimes.
