Mobile pressure settings, no pen?

Hello! I understand that if your device isn't pressure sensitive, it doesn't actually go off of pressure, and that it's based on the speed of your finger. Is there anyway to change this setting or make it more sensitive? going as fast as I need to get the line to thin out makes it difficult to have the line actually placed where I want. I'm used to using it this way, but figured I'd ask in case it can be any easier.
