iPhone 5s Looping between Apple Logo, Red Screen, and Black Screen.
I have an iPhone 5s that is in good condition, and nothing seems out of the ordinary inside when I opened it. When I turn the phone on, however, it shows the apple logo as if it were starting up, shows a red screen for a couple seconds, then turns off, and goes back to the apple logo. It repeats this infinitely until the phone runs out of battery, and then it gives me the normal battery needs to be charged page. What is wrong with the phone? Is it something that I could replace? I'm pretty good with fixing phones, but I just can't find out what's wrong.
Is this a good question?
