BangleJS touch stops working after first touch

Does D36.read() return true even when the touchscreen has stopped responding and the screen is definitely unlocked? That's the important one really.

Should I try flattening the battery? Is there a way to speed up the process on that?!

Yes :) Please could you connect with the Web IDE and run:

Bangle.setLCDTimeout(0);Bangle.setLCDPower(1);Bangle.setGPSPower(1);Bangle.setHRMPower(1);Bangle.setCompassPower(1);Bangle.setBarometerPower(1);

Then just leave it - it should flatten itself within 6 hours.

At one point I received a lot of these errors: Uncaught Error: I2C Error: Arbitration (start)

Thanks - that's really good to know. That'd definitely back up what I thought - it's possible I'm just running the touchscreen interface too fast in Bangle.js.
