The question is, is there any other way to remove the warning? Without using Xposed?
Since I was getting the "low charging speed" warning when using the qi charger I decided to try Xposed + Tweakbox. I worked fine and I removed the annoying warning.... But then I noticed that the phone wasn't as responsive as before. Since Xposed only works with dalvik my phone switched back to it. The thing is that I don't want use dalvik anymore. I loved the phone using art.
