LED Brightness

[Guest Azurren]

So last night I actually noticed that I had a missed call just by glancing at my phone the back-button LED was AT LEAST 2x brighter than normal.

I dismissed this as it being dark (It's winter after all) and went to put it on charge for bed

I turn my device off every night (Ever since that time that it only half charged and was buring hot in the morning, Froyo rom) and as the device was powering down the Red LED was just as bright but as soon as it powered off completely and started charging the LED returned to half brightness

Today the LED remains at half brightness for notifications

Is my SF faulty? (Is the LED supposed to be brighter?)

Or is this a general software problem? (In which case this could be solved with some hacking)

You had led notification on missed call ?..Are you using Froyo....I am with 2.1 and cant make it work ( the led notification) B)

Look closely, the notification LED is so dim you can only just make it out

This is my point :S

(Same as with 2.1)

We need a hacker to have aplay with notification LED to see if either the brightness can be adjusted or if the white LED that lights all 3 hardware buttons can be used instead.

The brightness of the LED cannot be changed asfaik. Setting it to 50 makes is just as bright as 255.

However the LED has four modes:

- Off

- Red

- Green

- Red + Green

Now if you turn on both Red + Green it doesn't go "Amber" as you would expect but rather light red. The difference you have seen is propably dark-intense-red (only red) and light-white-ish-red (red+green).

You can easily test this with adb (if you are root or running a custom ROM with ro.secure=0):

# cd sys/class/leds

(turn LED off completely)

# echo "0" > green/brightness

# echo "0" > red/brightness

(turn on green)

# echo "255" > green/brightness

(turn on red and go "red+green")

# echo "255" > red/brightness

(turn off green to go "dark" red)

# echo "0" > green/brightness

EDIT: And you can also play with the button-backlight in the same way: echo "255" > button-backlight/brightness
