12.9” pro screen brightness is changing by itself for no reason

[Padcatt]

I get that ios can “read” ambient light and adjust the screen accordingly but I’m noticing this i{ad screen getting dimmer then brighter then back dim again for no reason..the light where I’m at isn’t fluctuating/

any ideas? thanks!

Do you have Night Shift enabled?

 

[Padcatt]

I do..its set for 7p to 7a. I have seen the shift take place..gradually, but then stays put; doesn’t vary. For some reason now, it keeps changing.

If you are holding the iPad in a room with one or two bright souces of light, even small shifts in angle can have a big impact on the auto-brightness. This is especially true if you’re in a darkish room. I’ve experienced this in the past.

In that case all you can do is turn off auto-brightness.

I disabled auto-brightness, though I can't remember how. I use a free app that offers manual presets for two brightness levels:

‎Dimmer -Adjust LCD brightness- on the App Store

It's handy when I move between the two rooms where I normally use my iPad. For other situations, I use the slider in Control Center.

so..In turned off “night shift,” but left “true tone” on..I guess we’ see if that solves the issue.

thank you!

Is your iPad in a case? If yes it’s possible that parts of the case are interfering with the ambient light sensors

Could it be caused by whatever is on your screen? For instance, my backlit MacBook keys are affected by what’s on screen as well as the ambient light.

It’s been a long while since I visited the Display settings. I hadn’t realized the auto-brighness switch was gone.

It's now found in Settings>General>Accessibility>Display Accommodations>Auto-Brightness.

Inhave a UAG case...the material that grips the ipad *appears* to be minimal..where are said room light sensors so that I can check whether they are blocked?

The ambient light sensor is on the front next to the FaceTime camera.

Thank you—had not found that and I don’t like ‘auto’—usually keep mine set for less than auto would set
