Hi, my Galaxy S4 model GT-I9515 (Android 4.4.2) still has the video corruption bug caused by adaptive playback. I suppose you have forgotten it in your blacklist. See: https://bugzilla.mozilla.org/show_bug.cgi?id=1362921 See also: https://hg.mozilla.org/releases/mozilla-beta/rev/0884adb687d1 The GT-I9515 is not listed in the blacklist for 54.b08. It should have been mentioned in https://bugzilla.mozilla.org/show_bug.cgi?id=1362918 , but it was forgotten. Please be so kind and include this model too. Thank you.
