Lightning flash when sleeping

[Kittyfoster]

Something is causing my screen to have flashes like "lightning" when the screen is sleeping (black screen). This only happens on the black screen, never when the phone is in use.Verizon`s response is to get a new phone, as it's out of warranty. I do like my phone, but I'm flying to India next week and would be really ticked if the phone dies while overseas. Does anyone have any ideas, and yes I've tried a restart.

Do you have active display turned on? If so, does turning it off (in the settings app) change this?

I have active displays on; I'll turn it off and check.
Thanks- never thought of trying this.

Possible it needs a new display. Somewhat involved, but highly do-able.

I turned off the active display and so far this morning no lightning. Thanks for the tip!

I really like active display myself. It should be showing the time with an icon for the last app with an unread notification, or an unlock icon if there are no apps with unread notifications, but i was guessing that your active display was corrupt somehow if it was just flashing a light without the time or icon.

You can try turning it back on to see if it now works right, or, of course, just leave it off if you really don't need the feature.

This is what it should look like, and a lot more info about active display:

Well I turned active display back on and the flashing came back. Luckily I can live without active display!
Thanks for everybody's help!
