The other day I went in and got a replacement for my screen being loose, and when the genius gave me the new phone the sleep/wake botton had to be fiddled with in order for it to start working, after to he got it to work it started working great but low n be hold through the week there's been times it wouldn't work a time but then pressing it again it'll work, my question is what do I do if I can't replicate it to another genius? Do I find the genius I got the first time and hope he remembers me and believes that I'm having the issue? He did say if anything happens bring it back in but the botton doesn't do it all the time so it might not be able to be replicated.
