dude... I play on a really shtty phone, and I can make perfect lasers. just, when you use the zoom, -press zoom tool, press and hold on the desired area, and, as you hold, press the sound buttons. down for closer view and fine tuning, up for... your kind of projects.- that is why I can make the most amazing, perfect machines. whew!
