problem with LED transparent bar

[#1]

dear users.

I have 2 problem with transparent bar.

1- in low light (dark place) the leds not turn on. the operator of key works but light of LEDs turned of. In a light place they work correctly.

2- at the first use the keys(home, back, menu) have a short vibrate but now they have not vibared.

Regarding 1, have you installed any 3rd party software that affects the LED bar? If not, it seems there might be some issues with it, since there are not settings that can do this in the phone. I would suggest a software update/repair using PC Companion.

And for nr2, have you checked the box under Settings > Sound > Haptic feedback?

Did you update your phone to FW .184 ??

If not, Update n check..

For your second Prob

Go to Settings -> Sounds -> Haptic Feedback

Just Turn On Haptic Feedback..

Led light turns on, when we unlock the phone and stays on for time ( about a minute i guess ) till we use it, when we dont use it for some time, when using screen only. it turns itself off and doesnt starts again. until unlock/lock is done.

Same behaviour of button backlight is there in Xperia Neo V also, which i used previously.

I rely on intution for using the buttons, they dont light continuously for use.
