hii freinds my probleme is about the keyboard lights,he doesn't work even in dark room..and when i slide the keyboard the mobile doesn't unlock..so i did think that's a hardware probleme but after instaling the application Keyboard LEDs i found that they work well and i don't know where is the problème exactly
also when someone call me or when i make a call the screen lights doesn't switch on intel i unlock the screen by the unlock key,knowing that my notification LEDs works well
notice: i already did a vanilla flash but no change!!!!
finally sorry about my anglish
