Ok so I've tried everything I can think of. I've turned my brightness to all different settings, pulled my battery tons of times, left the phone off for a period of time, I don't know what else to do. My keyboard lights come on every once in a while for about 5 seconds. Other than that, the lights don't work. How do I fix this? It gets very frustrating at night because unlike most people on here I love the keyboard and it's all i use to type unless I only have one hand available.
