So my app was working fine until just today, when I got around to testing it with Beta 13, and now when I run it on my phone, it blinks erratically while running (even during the "This app has been created..." screen).

After doing some testing, it seems the "blinking" was caused by the fact that I had selected "Machine Independent Speed." I unchecked the box, and my app runs perfectly now.

The only problem is, I am making a timer app, with a counter that counts down every second. If Machine Independent Speed is unchecked, and my app is running on a less powerful phone, will the seconds potentially not be true seconds?
