I’ve run into this before, and unfortunately, it is almost always a hardware issue rather than a quick software glitch.

Here are the two main reasons I see this happen:

One is overheated screen glue. This is the most common culprit. The adhesive holding your display layers together gets baked from the phone running too hot and turns yellow. If it’s just glue damage, it’s mostly cosmetic, but harmless.

Another one is the swelling battery. If the yellow spot is caused by the battery expanding underneath and pushing against the screen, that’s a different story. Check your phone from the side. If you see even a tiny bit of bulging or warping, I’d stop using it and get the battery replaced immediately because an expanding battery can be dangerous.

Can you fix it yourself? Honestly, no. If letting the phone cool down completely doesn’t make the spot disappear, the damage to the screen panel or glue is permanent. If it doesn’t bother you and the phone isn’t bulging, you can just live with it. Otherwise, you’ll need to take it to a shop for a screen or battery replacement.

Honestly, I think USB-C is the absolute winner, and I am so glad the tech world is finally leaving Lightning in the past.

Here is how I see the big differences:

One. This is my favorite part. With USB-C, I can use the exact same cable to charge a laptop, a modern phone, headphones, and a gaming console. Lightning forces you into that exclusive “Apple-only” club where you need a special cord just for older iPhones.

Two. Ironically, USB-C is much faster than Lightning. It charges your battery way quicker and moves files (like photos or videos) to a computer in seconds. Lightning uses decade-old tech, so it transfers data at a turtle’s pace.

Three. I wouldn’t invest in Lightning anymore. Apple completely abandoned it starting with the iPhone 15, so it’s officially a dead-end cable.

For me, it’s a total no-brainer. USB-C wins on everything because carrying just one cable in your bag makes life so much simpler!
