Sorry, couldn't find the One X+ in the devices section. So, my brother's just got the One X+ afew days back, and he says whenever he's using the buttons at the bottom (to go back etc) they aren't shining up red. He's had a look in settings, and so have I, we can't find anything, would someone mind telling me how I can make it so they stay lit red? At least, whilst he's using them. Like on my S3, they stay white for 6 seconds after I've used them. Thanks.
