Guys, I might just found the solution for the yellow spots.
Rub the yellow area, rub hard a couple of times till it gone, use cloth, rub using your thumb.
try it. Works for me

, dunno whether its stays gone or not..

has anyone ever experienced touch sensor problem? it's like the screen is being touched by itself (in attachment pic, after i turn on the 'show touches' setting, notice the 2 dots on the right side of the screen?)
problem started few days ago. it happens everytime the phone wakes up from sleep. to stop the 'self-touching', i've to turn off the screen for a while & then turn it back on.
phone was updated to the latest ics last week, stock rom, locked bootloader.
Are you sure there's no body else in the room with you...

Yesterday, one of my relative got this XPS set which he won via Lucky Draw from his Company Raya Dinner, he did passed this set to me, ask me whether I should take this set as he is already using Iphone 4S.. I did read this thread from page 1 to 54.. I did check on the Yellow Tint Issue, as it does not show that and also checked that from Service Info, it shows Touch Firmware Version is 6 and also from back of the set, it show AC. So I believe this set is comes from 3rd Batch.. also it comes ICS out of box.. But only thing that I feel uneasy is this Set is AP (from Comsat)..
I am using this since this morning, so far no issue I encountered..
Should not have the problems, only the 1st batch like mine ap set, also the tint is not a big of deal, even found a way to remove it
