Touch not working. Apple Store says it may be swollen battery?

Thanks for the answer. I tried with multiple angles but couldn’t see anything. Only one other way to know. But between the risk of receiving counterfeit parts and the potential overall of battery + display assembly + labor I am not sure it’s worth it.

Edit: also screen borders are perfectly flush with metal borders and separation even on all sides. Swelling, if any, should have minimal effect on the screen assembly.

@wuming2 I don't blame you. Now a lot of repair shops use aftermarket, not counterfeit parts. Counterfeit parts would've been made by a third party that slapped an apple logo on it and called it OEM. Just be aware that although we independent shops use a lot of aftermarket parts, it's because apple doesn't sell them to just anyone without jumping through an unreasonable amount of hoops and we'll typically offer the repairs at a more reasonable price and even a better warranty. For example the iPhone batteries I use in my own shop are higher capacity so you get more run time. They are physically a larger battery but it's still well within the the spatial tolerances inside the device and they have proper safety systems like voltage, amperage, and temperature monitoring.

@hootonberg I understand. My experience of non oem parts arises from an old iPhone 5 I bought secondhand. Display was not working properly and even the lightning cable, to my much surprise, lead to overheating. Replacement at Apple costed almost as much as the phone itself but guaranteed years of useful life. This being said I am sure most independent repair shops just want to do a good job.
