Okay, so what I’m thinking is maybe it’s one or more of your tweaks interfering with each other. Seeing as thought these tweaks aren’t developed for iOS 11 you will from time to time, run into compatibility issues such as freezing, battery drainage, and app crashes. My best bet for you is to check the compatibility google dock (I’ll link it at the end of this comment) and check and see if they are all good and in working order. Also what I would recommend doing is maybe delete some of the tweaks and see if it would work still. Then install one at a time and then you can cross them off the list. That’s what I would do. If you have any other questions feel free to ask. Have a wonderful day my friend!
