I brought my iPhone 4S in to have the charging port replaced. I was initially happy that they charged $5 less than other shops and that they had the part in stock. I was also happy that I was able to pick up the repaired phone a few hours later.
After getting home I took a good look at the phone and noticed a major brown stain inside the screen. I brought it back to the shop and was informed that the screen damage was caused by the water that had caused the charging port to fail. When I had brought the phone in for repair the screen was absolutely perfect and I had no idea that the port had gotten wet. The tech was the one to discover the water problem..
I'm upset that the tech was negligent -- he didn't bother to deal with the water problem that he discovered. If he had dealt with the water, it's almost certain that my screen wouldn't have been damaged. He clearly understood that this was a potential problem because he took photos of the inside of the phone to document the condition.
The phone was partially disassembled during the port repair. There was a film of water on top of the battery and on the inside face of the cover. The tech mopped up the water that was on top of the battery. But he went no further even though he could see that the water had seeped a long distance through the phone. He could have easily pulled out the battery and mopped up the water that had seeped under it. It would have only taken a couple of minutes.
I'll never to to Tech Heroes again. They seem to be competent at replacing parts, but they also seem to have little interest in doing a good, thorough job. The screen on my phone became damaged while the phone was being repaired by Tech Heroes. This damage could have been prevented if Tech Heroes took adequate care.
UPDATE: After a month the discoloration on my screen finally went away. My battery died soon afterwards, so I ordered a kit and changed it myself. I now understand why the tech didn't remove my battery and dry out my phone. The old battery was glued in place and I ended up destroying it during removal. I'm not as upset with Tech Heroes as I had been when I wrote this review. But I still don't understand why they didn't communicate better with me about the situation.
