Yesterday I went on a tour and used euc world, everything works ok except I've had multiple times when I was changing between euc world and other apps, when returning to euc world, my screen went dark, I know the app still runs in the background because my pebble continues.
I have to lock my phone and unlock it again, to make euc world appear as normal.
If you want I can film this.
And the realistic battery level is a bit on the negative side, unchecked it's rather on the positive side.
For me the kingsong app is still the most accurate on this part.
