Thanks rkwan67... finally reached page 69 - i had taken 2 full days going through the whole thread! but of coz did not understand 100% since this is my first WM phone
how did you know i have a lot of problem bro?

i actually have 2 problem with this set:
1) Once i wake up in the morning, someone called me and i answered. after that my phone resolution / color / whatever you call it becomes bright, a lot of color out of sync... like i go to google panel, i can see it's all white color only... go to a lot of panels and menus still the same. finally press the power button up there (to sleep the device) and on again - voila back to normal. happened the first day after i bought it (scared the sh*t out of me) but never occur again till today.

i can juz hope it is WM problem not my X1
2) device cannot turn on suddenly on 2 separate occasion, i was wondering what happened but after trying to simulate it, i guess it happens when the battery falls to 2 bar. i cannot turn on the device even though a minute ago my X1 has 2 bar on it. actually just dropped from 3 bar to 2 bar in a few minutes then it happened. however now i charge the battery full when it reaches 3-4 bar, and till now it's working fine. i hope it's the battery problem
but dunno how to determine the cause... so currently my set works fine, and it's worth a try into WM world as the last time i bought a phone was 2 years ago (newly launched ori s500i) and it costs the same $ as this set.. so might as well try WM out to see if it fits me.. or i fit it..
other than that, the device works fine! juz i have not utilize it apart from using the GPS and phone capability, and a little bit of task and calendar setting. planning to utilise it slowly

with the help of forumers here!
omg what a long post.. i hope it did not get you guys bored .. well X1 rocks

I also have this problem. Whenever the battery level hit 30%, it will drop to 10% like nobody's business. And after that, my phone will turn off like the battery has been drained flat. Well, I guess it was drained flat because I couldn't turn on the phone even after I charged it. Hahahaha. Only after a few minutes of charging I could turn the phone on again.
