Xperia Z5 Adaptive brightness issue

Andrej123 — Sat, 28 Nov 2015 17:22:18 GMT

My all new Z5 has a issue with the adaptive brightness. It is way too dark. Even compared with my Z3. What can I do?

Z5 adaptive brightness way too dark

It is a different problem than the color distortion. The light sensor works but it seems that it is not calibrated. Indoor screen brightness is at a minimum level.

Not sure what can be done, but gotta say, my Adaptive B'ness (AD) works very well. The point here is that soo many different people, all with the one Phone model, find my soo many different issues and problems. Either we're all expecting something completely different or these phones are being manufactured in different factories, all with different processes, materials and/or specifications. Whatever the reason, $1,000 per phone is either a fine swan song for the Sony phone story, or a rip-off, or Sony mismanagement with manufacturing contracts. Read my Post 'Flaming Hot'.

I know what you mean, but my z5 was next to my old Z3 and the difference is amazing. The Z5 ist just dark with AB, it´s not a question of personal preference.

Yes..compare to my z3..the screen is also much dimmer. The adaptive setting works.differently. Not a big deal, just need to set the setting higher than the z3.

I've set it to 100% with AB but unless you put it under a lamp it's dark like the dim before the screen turns off.

I too am having problems with the white balance on the selfie camera when trying to film. I've changed all the white balance settings and the moment I press record, it turns dims (drastically too). I have only had this camera phone a couple of days and am still in my 14 days grace period to try it.

Is there anything I can do to change this? Unfortunately this is far worse than my z1 - yes, the main camera is better, but I don't use this as often and if there isn't anything I can do, then I cannot use this at all and will have to swap it for a Samsung.

I'm extremely disappointed and this is a deal breaker as I film a lot of tutorials for my YouTube channel.

Hello

I purchased Z5 Compact a couple weeks ago & had the same very low adaptive brightness issue when in a shaded room - it was fine when outside.

I found the minimum brightness level is controlled by the "Quick Settings" menu (the one that you get when you swipe down twice from the top of screen) - it has a sliding brightness adjuster.

Once I set that slider to 50% the adaptive brightness never went below that.

Hope this helps someone.

Tried that (the Quick Settings slider), but doesn't work for me. Did it work for anyone else?

If I crank up the brightness with this slider (let's say to 75%) before I turn on AB, the phone dims as soon as I turn on AB (I am indoors w/o bright lighting).

After that, if I return to the slider it sits at 100% so with this, I can only dim the brightness even more.

Apparently when AB is on, this sliders '100%' means: '100% of whatever AB comes up with' so you can never get more brightness than that.

Notice, when you turn on you Z5 the screen is really really bright and just before it's fully powered up, contrast and saturation drops really heavily!?
This is done by software. Even with auto brightness turned off and screen brightness turned to maximum. It's ridiculous.
And really annoying!

Ambient Light Sensor test (Adaptive Brightness problem)

harrienak — Thu, 06 Oct 2016 15:42:20 GMT

Hi all,

Can someone look at my Ambient Light Sensor test experience and tell me if this is normal? See below!

Background:

I am still having a problem with the Adaptive Brightness: indoors, with only atmospheric ambient lights on, the screen is always a little too dark. However, when going outside or in brightly lit rooms, the screen adjusts just fine.

Other people have reported this issue but I have not seen any solution yet aside from switching AB off, which imo would be a shame since it's such a convenient feature.

In an attempt to find out what's wrong I performed a Service Test of the Ambient Light Sensor. Moving the phone around I notice the possible measured value seems to lie between 0.0 and 30000.0.

The 30000.0 is reached when briefly pointing a bright lamp right at the sensor.

Outside, on a cloudy afternoon, it measures around 400-500.

In a reasonably well-lit (bath)room, it's around 60.

On a shadowy spot on my desk (a typical place where the screen gets too dark), the value goes down to 13.0 or 6.0. Below these values there is only 1.0 and 0.0 - I get this when I hold my hand over the sensor at around 1 inch (2,5 cm) distance (so there is not much light reflecting on the phone anymore, but still some!)

The (13.0/6.0) shadowy spot is still bright enough for me to be able to easily read written sticky notes. It is also bright enough to still be able to read the 'SONY' and 'XPERIA' logos on the back of my (black) phone.

Questions:

- Is my ALS working as can be expected?

- Is there a way to structurally increase the brightness at lower ambient light values?

Thanks!

I guess a forum moderator merged the new thread I created with this older thread.

If that's the case, then could this mod also please remove the 'SOLVED' flag from this thread? The original topic starter apparently defined his own post as 'accepted solution' while there has not been any solution yet... Thanks! (P.S. is there any way to contact the mods for this kind of remark?)

I'm not sure whether that's directly related to this topic's issue but indeed it appears as if 'full brightness' is the default value - eg whenever you turn AB off, it will briefly go to full brightness first before settling at the brightness defined by the slider. Perhaps the better option would have been to make 50% brightness the default value... Is that what you meant or is it the drop that annoys you? :smileysmileywink:

If you have any spare time, could you perhaps have a look at my little sensor test and compare it with your own findings?
