Flashing grey at the top of the phone

Hi kenfromhighlands,

Thank you for participating in the Apple Support Communities.

It appears that the screen on your iPhone is not behaving normally.

In this situation, I recommend these troubleshooting steps from the article Get help with the screen on your iPhone, iPad, or iPod touch:

If you see lines, missing sections, discoloration, or poor image quality

1. Try to restart your device. If you can't restart, reset your device.
2. If restarting or resetting doesn’t fix the issue, restore your device.
3. If you still see the issue after you restore, contact Apple Support.

Sincerely,

Jeremy

Hi Jeremy,

I'm having the exact same issue as kenfromhighlands above,

I done all the steps you suggested, and I contacted Apple support, they provided me with a Brand new iPhone 6 Plus 64GB. 1 hour after receiving this brand new device, it started becoming non responsive and has a flashing grey bar at the top of the screen..

How can this be explained? I will be calling back to the Authorised Service Centre on Thursday and I'm fairly sure I'll be without my device for another week.
