iPhone 6 screen turned black and white, please help?

I'm using an iPhone 5s running on iOS 8.1.3.

Just yesterday and for no apparent reason my screen went black/white. I tried all the suggestions in this thread-short of going to a Genius Bar or backup/restore- to no avail.

By fumbling around I lucked into a solution.

I triple tapped the home button and un-checked the "zoom" option and color returned.

For whatever reason- I'm assuming a bug- toggling the "zoom" option changes the screen from b/w to color (Zoom on=b/w; Zoom off=color).

Interestingly, turning on/off the Zoom in settings>general>accessibility>Zoom (under the "vision" heading) does the same thing.

My phone has gone black and white

I have gone to settings

General accessibility

But there is no gray scale setting on my phone to turn back on

I am finding the phone very difficult to use

Should I buy another one?

Colin's Post did it for me too. Awesome stroke of luck! Saved me hours of headaches. Thank you!

Also, try triple-tapping screen & selecting "none" from the "choose filter" option in the menu. It took me hours to figure out that I'd inadvertently turned the "grayscale" filter on while the screen was unlocked & in my pocket.

This just takes a photo

Same with me. So far no HELP!

Could you please give more information? What were you doing when this happened? Did you drop or otherwise damage the device?

I would back up and restore the software. If that doesn't help try restoring as a new device. If it continues, your device is under warranty, so take it to the Genius Bar to have it evaluated (make an appointment first).

First try a reset of the iPhone. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.

If that doesn't work try the back up and restore that AmishCake suggests. Still no luck? Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

I'm also using an iPhone 5s whose screen had changed to Black & White (monochrome, greyscale). Colin1069, your fix helped me too. But afterwards, I also had this little movable window stuck on my screen. I triple tapped the screen to bring up the Zoom Window and Window Zoom had been turned on. This allows you to see portions of your screen while zoomed. BTW, when "Full Screen Zoom" is an option from the menu, this means if you select this option, it will be active so when you see it, "Full Screen Zoom", it's in Window Zoom mode.

I have exactly the same problem (but on an iPhone5S on IOS 8.3). I restored as a new device (just restoring the software didn't fix it). After restoring the device (as a new iPhone), the problem was fixed, UNTIL i then restored a backup, after which the problem came back. This lets me conclude that my iPhone isn't broken, but it must be related to one or another app installed. Is that possible?

Thank you Colin for your helpful reply.

This just happened to me this morning using iPhone 6 Plus IOS 8.2. Deselected the window zoom and it fixed the problem straight away.

Must be a bug that isn't sorted yet.

Actually I now don't believe it's a bug.

If you have selected to use Zoom on your iphone, you can triple tap the your screen to bring up the zoom options. In these options you will also find "Choose Filter". If you select this you will probably find a tick next to "Grayscale".

Select "None" in this window and the problem should be solved.

This problem was fixed in the same manner on my iPhone6, thanks to you Colin! Tree repeats on the home button and then uncheck the zoom option under the preferences. The only thing is that now It´s not possible to use the zoom without all of the screen turning B&W again. I guess that problem will be solved in the next update from Apple?? Support add this to the BUG´s list! 😉

Thanks for sharing Colin1069!
