[ONE Q&A, Help & Troubleshooting] Quanalogy:
Hi :)

I've been using Juicedefender Ultimate for over a year now, and have never experienced any problems with it. I've just a clean update to Lollipop CM 12 Nightly. Now Juicedefender Ultimate keeps crashing - both when i'm opening the app and wifi isn't activated (instant crash) and when i lock my phone and wifi disconnects (which is a setting i prefer in juicedefender). I can see from the log that they recommend that i reinstall, which i have tried both in play store and in root browser - same problem. I have tried to factory reset the phone, same result. I've come to a point where i don't know how to proceed, which is why i write to you.

I've got the crashlog here:
