iPod Touch 6th Gen touchscreen responsiveness

Hello all.

A few weeks ago, my iPod Touch's screen started having issues with responding to my touch. For instance, I would be playing a game, and when I was holding the "joystick," the responsiveness started "flickering," so it would be fine then start quickly becoming responsive then unresponsive multiple times a second.

I used to fix this by rotating my screen and using the other side, but then it would start on that side as well, and I could only stop this by turning my iPod off and leaving it for a while. This happens for all my apps. My matte screen-protector is clean; I clean it regularly, there are no bubbles, and my screen isn't cracked or scratched.

From what I have seen on the Apple Support page, they recommend resetting my iPod, but I would prefer to not have to do that.

Thank you for any help you may have.
