Lost my lockscreen
I tried Shaky and got it to work after a reboot or two, but after about a week of use I lost my lockscreen security. I don't believe I changed any settings to make this happen, it just seemed to happen out of the blue. I tried to reset my pattern to PIN and neither were working. I uninstalled the Xposed framework and rebooted and it was asking me for the PIN I set. So after re-installing the framework my security was lost again. Open right up to the home page.
Just because Shaky relates to the lockscreen I uninstalled and rebooted and my phone is asking for the PIN again. I saw shaky as a deterrent if I ever was struggling with someone over my phone or got into an accident or dropped it far (most likely) that Shaky would automatically lock my phone before someone gets to it. But I can live without that, so I'm going to leave it uninstalled. Good luck, and if you'd like to follow up I'd be glad to help.
