Just go to Apple, spend a little more and save yourself the stress. I had Apple replace the battery on my phone and everything was fine after that. Then I cracked my screen and had this place replace the screen. After that I started to see hot spots and dark areas. The guy at Microfix blamed Apple for putting my battery in incorrectly causing pressure points. Again my phone was absolutely fine from the time my battery was replace until the new screen was put in. However, to give this place the benefit of the doubt, I took my phone back to Apple to see what they had to say. They told me the glass used here is NOT Apple and is thicker than the glass they use, which is why I have pressure points now. Both this place and Apple seemed to have valid points, but at the end of the day, my phone was fine for months after I had my new battery and only started to have issues once I came here. So again, just suck it up, make the appt., with Apple and pay the extra $20-$40 depending on what you need. You'll be much happier.
