So I brought my iPhone into my local Apple Store to get a replacement iPhone because of battery issues (it's not lasting nearly as long as it should be) and because the fingerprint sensor on my iPhone stops working every 3-4 hours and only works again after a reboot. I took a video of the fingerprint sensor not working and went to the Apple Store the next day (today) and showed it to them and they said they can't replace it because of the battery because it's showing up as normal and they can't replace it because of the fingerprint sensor because there is no way for them to test it. I'm now out of my 14-day return period with a defective phone. Any suggestions? Should I call AppleCare?
