Not just you. Changes in the (auto) brightness were mentioned in the release notes, and I also noticed that after the update the screen is noticeably darker with the same setting. Can't tell if it's good like this or not before testing in daylight.

Also the difference between darkest and brightest is practically nothing. I have also set 100% brightness, but when the sun is shining I cannot see anything on the screen, even when I take my sunglasses off. Edit: Just realized you were talking about the newly released version, I have this issue with the previous.

Same here. From playing a bit with it it seems that the light sensor is affecting it.

From list of bug fixes:

[BUG] Adaptive brightness does not do anything noticeable when brightness is set at max

So, I guess it now does something noticeable :)

Now after the update, the screen seems to be a bit darker. And light sensor does nothing, as with the previous version. Also tried not 100%, but still didn't notice anything with the light sensor. =)

First off: In direct sunlight just boosting the display brightness is not enough -> the colors used etc needs to be changed too. There are some plans for that in the pipeline.

Overall: In the manual mode users can now choose the brightness level more freely. In the automatic mode the display should go darker than before in dark environments and should reach maximum brightness with less light than before.

Previously there were 5 manual settings (N * 20%, where N=1...5) and corresponding 5 automatic profiles. The 2 brightest automatic profiles had quite high minimum brightness which made the display stay rather bright even in complete darkness. Now the manual setting is direct 1-100% and there are 21 automatic profiles (chosen roughly like: setting/5) -> you probably need to find a new setting that is closest to your liking. The top end profiles will not use the minimum brightness possible, but do go dimmer than before in darkness.

Additionally there have been some changes to the ambience handling, which can contribute to how dark/bright the display is perceived.

There should now be a display brightness difference when:

  • setting is changed while the lightning is kept constant (but not in either extreme)
  • setting is kept constant and light (seen by the sensor) changes (enough)

If you do not see any difference, try to:

  • wipe the sensor area (top right corner on front face, closest to the power button) with cleaning cloth
  • select dimmest automatic setting (which has the biggest dynamic range)
  • repeatedly cover the sensor (=darkness) / shine light on the sensor and observe
  • if there is still no change, try rebooting the device (just in case the sensorfw is acting up)

If the adjustment does happen, but you can't find comfortable setting: feel free to complain and the quest for finding a solution that will annoy as few users as possible continues.

Doesn´t get bright enough with any trick. Could it be possible even to adjust all font colors to white or freely to any color? In some moods it´s hard to see letters even in bright display on dark background. Anyhow colored letters look a bit 80´s video production.

Same weather in Helsinki ;) I have to look for a shaded place when I write an SMS even though I have the "summer ambiances" in use. Yesterday I sent an :( smiley instead of an :) because I couldn't see the characters :D ...and yes my eyes are just fine.
