Hi all, new forum member here.
I created a profile just to post a thanks to all who have worked through this issue and posted the fix for it. I too was experiencing the low watt firing issue while in stealth mode with the screen off. Having reset everything to factory default I concluded it was not anything I had done, or the themes I was using had caused, so came here and found this thread. Loaded the experimental firmware and it fixed the issue immediately. Back to being a happy DNA100C user.
Thanks again!
