I think i should re-title this bug because brightness works but it does not adapt properly.
For my understanding the real bug is the brightness will only adapt if there is a difference between two readings within 4.5 sec when it is turned on. So in very dark conditions when your phone is turned on there in no variation in brightness and the phone stays at the original brightness that when you turned it off (see comment #14) which could be really bright. To easily reproduce this bug follow this steps. >Turn off auto brightness. >Put manually the brightness to maximum >Cover the proximity sensor with your finger >turn on auto brightness ==> expected the brightness to be corrected from maximum to minimum Bug => As long as you keep your finger on the sensor the brightness is kept to maximum. As soon as you remove your finger from the sensor and approach it from a light source, count 4.5 sec and you will see the brightness changing cover the sensor again and 4.5 sec later it will be at minimum brightness where it should have been. In user case. In a dark room when you turn on your phone the brightness will never change (That's the reason i thought the brightness was broken) ** Summary changed: - Regression: Rc-proposed Nexus 4 autobrightness does not work + Regression: In dark conditions autobrightness does not adapt ** Description changed: OS ubuntu 15.04 since bq-aquaris.en/mako r.380 autobrightness does not work anymore + See comment #17 for a better description of the bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1613871 Title: Regression: In dark conditions autobrightness does not adapt To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1613871/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
