I updated the Facebook app to v318.0.0.27.154 on Xiaomi Mi 3W (16GB). Still no photo can be uploaded through Facebook (com.facebook.katana) app as the screen turns black and the system becomes unresponsive after entering the camera roll to select photo(s), whether that be at the timeline, 'comment' or 'reply' sections.I just tried the facebook on my Mi3, and the gallery shows up correctly without any problem.
And i don't see any strange dialogs on Play Store.
