If all you want is to prevent the phone from being turned off at the lock screen then just use that new tweak LockSafety.Which of the two do you recommend? I just want it to disable the device from being turned off
Both iCaughtU Pro and iGotYa have more features than just this. If that's what you want then the only recommendation I can give you is to do your research to figure out which one works best for you.
iCaughtU Pro has a free version with less features simply called iCaughtU. Not sure about iGotYa because I never used it. I chose iCaughtU Pro because it seemed to have more options (at the time) than iGotYa.
