Just shake your phone =)
(If does not crash, shake it twice, works 100% of the time)
This is happening due to high voltage of the power supply. It makes the circuit work so fast, that the time limitation of the program makes it not workable, processing the circuit infinitly.
If you wanna make it workable, just set the battery to 5V and the time speed to 100ms. (You can shake the phone to start the circuit instantaneously or wait ≈5 seconds to make the circuit unstable itself because of real numbers inaccuracy)
Note: this circuit will not affect your program, just restart it after the crash.
