Heh, whenever I hear "calibrate the screen" I assume you either work at an Apple Store or have been to one recently, as that seems to be their favorite line. Calibration is only necessary on a glass-only repair; it realigns the digitizer "touch web" with the top glass that you're actually touching. That's why we don't perform nor recommend glass-only repairs. When we repair a screen, we test every part of the digitizer before giving it back to the customer. We type on the keyboard, open apps, etc. If we find a dead spot, we replace it on-site. If by chance there's something we missed on our test, that's why our warranty exists. If a customer finds a dead spot or the digitizer starts glitching, that's covered under our warranty. And that's why I recommend you find a shop with a good warranty. Most of them don't test as thoroughly as we do, but even with testing, a small percentage of digitizers will still have issues a few days to a few weeks after the repair. A warranty will get you a no-hassle replacement as long as you haven't cracked the screen.
