Screen Brightness Xperia 10 V

[MeeGo-Junky]

I am bit puzzled because the screen of my Xperia 10 V under Sailfish OS is very dim.
I set brightness to maximum under settings but the device cannot be used outdoors during the day, except for very cloudy days.

Why does it appear strange to me?

• According to the specifications the screen of the Xperia 10 V should be much brighter than the Xperia 10 iii
• But under Sailfish 4.6.0.15 and 5.0.0.55 maximum screen brightness is much LOWER on Xperia 10 V than on Xperia 10 iii.
• even 2012 Blackberry Q10 is brighter, which is totally confusing and contrary to all published specifications: the HBM of Xperia 10 V should be around 900 nits

Why do I exclude faulty hardware?

• under Android (Stock ROM, rooted and AOSP) the screen is nearly as bright as the current Samsung Galaxy devices, something that reflects the soecified 900 nits HBM
• when I flash back to SailfishOS, screen brightness is crippled again

So it is specifically the combination of the device Xperia 10 V with SailfishOS.

Questions from my side to this:

1. is anybody else experiencing the same? Or am I the only one?
2. is there a setting under the hood beyond the usual slider in the settings app that can be tweaked to increase screen brightness and get rid of this strange SailfishOS limitation?

Currently the device (which is nice btw) can on the Iberian Peninsula only used indoors or after sunset😭. My hope is that configuration files can help here (and please, NOT the dependency on some Sony pre-alpha blobs that might be available in the year 2525).

What is your experience with the 10 V and screen brightness using outdoors? What does the audience here think?

Have you checked display settings > adjust brightness automatically?

[MeeGo-Junky]

Yes, checked, it’s on, settings identical to my 10 iii

[hattu]

Try to put it off. I Don’t know about 10V, but after 5.0 update my 10 llll automatic was on and display was very dim. I put it off and the world was very bright

[MeeGo-Junky]

Negative, does not change.
Identical behavior on SFOS 4.6.0.15 and 5.0.0.55

Bad luck. It’s very annoying when display is not bright enough. Maybe some developer can help.

I use as my daily the XQ-DC72, and I think I experience what you are saying. In full sun, the display certainly seems to dim right down, to the point that it is either unreadable or scarcely readable. The phone seems quite capable of good brightness, indoors on max brightness. But it doesn’t seem to provide max brightness when there is full sun.
Seems to me that the way the OS interprets the light sensor data is a bit broken or something similar.
Thanks for chasing this issue up.

You excluded hw, but your device may suffer from foulty light sensor. Android may have compensation for this, sfos probably not.

But whatever is true I won’t be expecting improvment anytime soon. As for Jolla right now different prios exists.

C2 → Mind2 → Maintenace of fully supported devices → Sony Blobs and then 10 IV&V

Hate to say it but Jolla probably won’t make a move on IV&V until new blobs are released

It may even take more time if current blobs are ok and they just continue to say it’s sonys fault because if that is true we really have no idea what’s goin’ on.

Maybe it should be new trademark:

Did you check the functionality of your light sensor with the csd tool? This might be helpful and shed some light on the issue.

[MeeGo-Junky]

That is indeed something I did not consider: a potential compensation within Android OS of a impaired light sensor. Might explain my observations…

I fear your prioritization listing might be correct and we have to wait a long, long time and are victimized by the current situation with Sonys alpha blobs and Jolla wating and low priority

[MeeGo-Junky]

Yes, tested it already a few weeks ago, did in between forget about it.
Here is the result of the repeatition today, looks okay.
Based on this the light sensor appears OK
