yes you can. Just open up the media player and play a song or something. Then put the volume to lowest as possible using the volume keys then...

check if your media player volume button. The speaker like on a computer sound.

Now if you see it at low like when you did it with the key press, then press the volume key to increase the volume to max. Check your on screen volume button again. You'll see it is not updated.


Edit:
Damn now it updated like it should lol. WTF is wrong with my device earlier. Should have taken screenshot to prove it. Oh well. I think in this case it just the OS is still not yet stable. My guess that's all. SOrry bud. Mod Please disregard my post.
