• Perhaps the most common hardware problem is a damaged screen. With a damaged screen, you can barely see anything on your iPhones, which can be irritating at times. While you're certainly eager to learn how to repair or restore a damaged screen, for the sake of time, this section will walk you through the various issues that might arise with your phone screen, beginning with the more minor ones.
• Screen that is completely blank: It's possible that your iPhone's screen is blank because it's no longer well-connected to its printed circuit board, or PCB.
• If your iPhone won't charge, it's likely due to a faulty charging port or cable. As a result, you'll need to diagnosis the device first. The best way to do this is by using a different cable if it works with your iPhone. If it does, the fault is with the prior charging cable, and it's time to get a new one.
• Phone batteries, like any other piece of gear, have a finite lifespan. It normally depends on how you use your iPhone, but if your battery drops from 100% to 20% in less than an hour, you're experiencing battery failure.
• You'll find that the camera on your iPhone produces increasingly low-quality photos over time. This is due to the fact that the camera, like any other piece of gear, is subject to wear and tear. Scratches, scrapes, and other damages to the camera might cause photos to appear cloudy, hazy, or foggy.
