Don't really know when I got the dead pixel. I notice it sometime when watching YouTube video, and thought is just a video defect. After few weeks, I keep noticing the wrong color on different video at around the same place. So I went to display some plain color image, like black, blue, purple, etc. It is only then I realise this was a dead pixel. I had experience with dead pixel before so I know how to spot it. It is not noticeable on all the colour, just some of it.
My location is Malaysia, Kampar, Perak. I thing the nearest city would be Ipoh.
I am a bit reluctant to send it in for warranty, as I would need to backup and later re-set up my phone all over again. I am planning to just wait and see, and if the dead pixel get worst, I would claim for warranty, if not, I just let it be. Would that be okay?
