Backlight notification (BLN) on Samsung Galaxy S II? Yes, it is not a dream anymore. Using NoLED on Samsung Galaxy S2 does help to get notified when we have missed call, SMS or email. But it eats a bit more battery compare to backlight notification. Therefore, BLN is the ultimate solution for Samsung Galaxy S2 users. Too bad that Samsung did not enable this feature on stock firmware. But no worry, there is backlight notification for SGS2 users now.
