i know this has been discussed before... but was there any outcome. sorry but was not really able to online the last few days... perhaps can put this as FAQ?!

Q1. Hissing sound from the charger. I do get that as well. Have read many users also faced that. I recall someone replying that it could be due to grounding or sth like that. The thing is... this hissing/ buzzing sound... is not really loud and i noticed that after a few hours, the sound is no longer there (especially if charge overnight and try to listen to it the next morning).

Q2. While charging... I noticed some parts of the screen is not as sensitive. again, I recall many also mentioned this and again, could this be due to grounding?i didn't get this with sgs2. Will both Q1 and Q2 kill the Note over long term?

Q3. Yes... This phone does lag a bit. It could be just after waking up the phone or something... But sometimes, my touch takes 1-2 seconds to register. it usually happens at the beginning when i start to use the phone -- maybe the phone just woke up or something. example: i touch the message button and sometimes  it takes 1-2 seconds before the message screen appears. again, comparing with sgs2, i've not faced such a thing before. still, in 1 day... maybe this happens only like 2-3 times la... so its a small issue.
