Red spot on black screen of iPhone 6 plus

I've never seen that. The only way to rule out hardware is to perform user troubleshooting. First step is a restart. Power the phone off/on. If it returns, then a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone will reboot. If it returns, make a backup of the phone and restore the phone to that backup. If after that, it still returns, then make a backup of the phone, however this time restore the phone as new, not from the backup. Do not add any additional content to the device and see if it returns. If it does, then you have a hardware issue and you need to make an appointment at the nearest Apple Store or your Authorized Apple Service provider. The restart, reset and restore from backup will not affect your data. However, a restore as new will delete all data from the device. Make sure everything is synced to a supported application to recover and import your photos and other data.

Any updates on this? My iPhone 6+ just started doing this today and I am not very happy about it. First my camera is foggy, now my screen is getting red spots. I have had every iphone and I have had far more problems with this one than all the rest combined. Makes me worry about other new Apple products.

User troubleshooting steps are restart, reset, restore from backup, restore as new. Also, the 6 Plus has a camera program for certain serial numbers. See if yours is one for the camera program here. https://www.apple.com/support/iphone6plus-isightcamera/

At the same time you make an appointment at the Genius Bar to have that looked at if you are a part of the program. If there is a problem with the device, Apple will take care of it.

I'm having the same issue with my 6s Plus. Apple solved any of these previous cases?

Since there were only 3 people reporting the problem, with the first a year ago, I'm guessing they got some type of resolution, however you would need to contact Apple for resolution with yours. Since the 6s Plus would still be under warranty, make an appointment at the Genius Bar of the nearest Apple Store to have the device examined.

Responded to old post.

I have an iPhone 6s Plus and within the last few weeks I have noticed the same thing. It looks like a small faded "splotch" of red on black backgrounds. Kind of annoying.

Then follow the steps outlined in this thread. Troubleshoot, or since the device should still be under warranty, make an appointment at the Genius Bar to have it examined by Apple.
