My S6 Edge can't keep up with my typing

This problem is intermittent, but I cannot stand it when it happens. Usually, I type pretty quick. But sometimes, if I type my normal speed, it skips tons of letters and changes those words to others that were nothing like the one I was typing. It is SO frustrating. It makes me type at what would seem 10-20 wpm. It's like Samsung installed a typing speed limiter. Is anyone else experiencing this issue? If so, are there any fixes? Is it hardware? Software? I've seen only a few other posts over the internet, and no answers yet. I don't know if it changes/helps anything, but I cracked my glass on the bottom left edge. The touchscreen accuracy is still right on. It just sometimes has a delay that completely screws up my typing experience.
