So I've had 6.1 Jailbroken on my iPhone 5 since the first day Evasi0n came out and this problem has been prevalent ever since I jailbroke. I'm not sure if it's just a bug that's only happening to me or if it's just a bad jailbreak and I should completely wipe/redo the jailbreak. When I'm listening to music, every couple times (say 5-6 times) when I turn the screen on to check a text or do anything else my screen stays black after I lock it. Music is still playing but none of the buttons are responsive and the screen is stuck on black, forcing me to reboot the phone. It's not a very fun process and I hate having to restart my phone five times in an hour while I'm listening to music. =/ I don't know if this is a known bug, it seems to just be happening to me. None of my friends are having this issue. I don't think it's any of the tweaks either, cause it happened before I installed custom tweaks, and I've only installed things that I know are compatible with 6.1. If anyone else is having this problem or know of a fix please let me know! Greatly appreciate it.
