I2C bus failure during fast keypad presses (for example during screeshot)

[zytegalaxy]

I was trying to get a screenshot on v1.0.0 where suddenly the system crashed. I think we need to have a way to recover from this. As it can be seen in the error, the exception is thrown where the light sensor cannot initialize the I2C bus. I believe there was some sort of conflict (collision) with keypad I2C bus events.

I suggest we have a refresh keypad or reset I2C bus, to run for recovery while we investigate the root cause to hopefully eliminate it.
