Auto brightness goes too dim when ambient light is low

Sunking1011 — Tue, 08 Nov 2016 16:20:13 GMT

In the pitch black of night I find that the auto brightness on minimum is fine but sadly in low light conditions the auto brightness also defaults to minimum and the screen is just too dark.

Is there any way to calibrate the auto brightness so that the minimum setting isn't zero? Unless I'm in either a very bright situation or a pitch black one, my screen is way too dim.

There isn't BUT you can pull down the notification bar and change the brightness.

Yeah I've been doing that but it kinda defeats the purpose of 'auto' brightness. There are just so many little annoyances with this phone.

No, it doesn't.

In Android 6, when your phone is working in "Auto brightness" mode, the brightness slider does not override the "auto" setting. It simply fine-tunes it. By manually moving the brightness slider you tuning the "auto" mode to your preferences. You are basically telling the phone to stay in "auto" mode, but be brighter or dimmer than the default "midpoint" setting.

In previous versions of Android, trying to manually move the brightness slider would immediately disable the "auto" mode. That did indeed defeat the purpose of "auto" brighness. But not in the modern Android. In modern Android "auto" mode and brightness slider work in concert.

So, if you believe that the default "auto" brighness gets too dim in the dark, just move the slider to the right until you like it better. You are not defeating "auto" brighness by doing this, you are simply fine-tuning "auto" brighness algorithm to better fit your preferences.

Auto means auto, ie no user input required. My iPhones managed the screen brightness perfectly without my intervention...

"Auto" with fine-tuning access is always better than "auto" without fine-tuning access. There will never be any "auto" that works out of the box with "no user input required", since there will always be people who'd prefer it to work slightly differently (or a lot differently).

If you are happy with the way your iPhone manages brightness "with no user input" - good for you. It means that you belong to the subset of people who happen to be happy with the hardcoded iPhone "auto" brightness setings. But that's not everyone.

I've had the same issue. Every time it gets to minimum when I don't want it to, I use the slider. But it still goes back to minimum every time. How do I tune it then?

@Liamg91

You will have to give us more info on the issue, you can also repair the phone with XC and report back.

It happens to me occasionally too, mainly in dim light.

Tried Xperia companion to do software repair, it didn't fix it. So I took the phone back to the shop and got an exchange for a new one. The exact same thing is happening with the new phone so I'm guessing it's some kind of software issue?

Re: Auto brightness goes too dim when ambient light is low

Sunking1011 — Tue, 03 Jan 2017 13:15:12 GMT

It's more than likely a software issue but it could be a hardware fault that affects all of us. It's the same with the faulty double tap to wake, is that a software issue or hardware? Again probably software but Sony certainly aren't patching it are they.

it may be software or hw iussue. hope sony will solve it with a new fw if it is cause of the sw.
