i've been using w810i for around 5months, and got no problem so far(hope this will remains in the future).bout the 'buzzz' sound..i've never experience that before as i always listen to music using my headset on.cause i sked my phone speaker burst and listen directly from the phone consume more battery as you can feel the heat from your phone.

actually, you can fast forward or rewind while watching movie, just tab on the arrow button (either left or right) from the directional arrow. hold on it, then it automatically will ff or rwd.

overall,i guess this phone is just fine for its price,aint paying for rm2k or so.for a rm1k+ phone i guess that's all we can get.hmm..just the problem with my camera button.its hard to press sometimes.but yet..it is still functioning.
