Hi!
I've had my Xperia U for about 2 months now, and I've come across a problem with my LED bar. It suddenly stopped lighting up, even when I pressed the capacitive keys or played music or viewed pictures. I tried rebooting my phone and that helped. The LED bar started to work again BUT now it looks dimmer than before. I know i'm not just imagining this cause the light became really faint, and when i try to reboot it again it would light up real bright and then get dim..and then stay dim 
When i play music, there are times when the previous color gets stuck. I've also tried hard reset but that didn't help.
i've only just also noticed the bubbles formed inside the bar (as mentioned in one of the threads) and although it sounds stupid i was wondering if that was related or anything? or if not can you just tell me how to fix it please? I bought the Xperia U just because of that LED bar, i didn't even mind the not-so-good camera nor the network issues. 
PS i've already updated my software to the latest version, and with the previous version i had no problems with the LED bar (just the network issues)
