Hi there, I started using smartmax governor more than a week ago, and since then no black screens. Can you test and see if it works for you..
(Before that i was getting at least one black screen a day)
@Fonz93 I had a black screen last night, pulled the battery and restarted the phone, after the long reoptimisation I discovered that more than half of my apps have lost their data and settings. Is there any explanation for this bug? It's the same that happened to me with CM12
