I play on a OnePlus 2 A2005.

The fire charge is extremely glitched out and when fired from a dispenser goes very far and does not ignite anything. When you put a block infront of the dispenser and fire it, it does not light up the block right next to the block infront of the dispenser.

Steps to reproduce:
1) Put button on top of dispenser and press it. Watch as the fire charge does something ridiculous.

2) Put button on top of dispenser and put block next to dispenser face. Watch as the fire charge rarely do something if anything.

Sorry for the lack of screenshots, it's hard to screenshot this.
