Notification Bar Activates When Touching Below the Bar

I had my battery replaced last week. Upon receiving it back, I've noticed the notification bar will pull down even when I touch about 1/2 inch below it. For example, touching the Twitter home button in the top left corner will pull down notifications instead of taking me to the top of my feed. I've re-calibrated the G-sensor, factory reset (keeping on a flat, level surface), and rebooted in safe mode. The problem persists. The company that replaced my battery said they ran all of the troubleshooting they could find. This issue seems to be a hardware issue and not software. So my question is twofold. First, has anyone else ever experienced this problem and, second, could the company have damaged something internally causing this issue?

Thank you in advance for any help.
