YouTube works fine for me , mind to share what problem your device shown ?
I cleaned the caches and everything is fine. I don't surely know what the reason was. Thanks all the way.
So I flashed before a day or so and I'm loving it! You did a great job but still its not a daily ;/. I found problem with YouTube but not with Facebook videos which was strange for me. I love using it but I found the battery life little bit strang...
