Auto-brightness on cell phones
At work here, a co-worker complained that her phone gets very bright in the dark and is so dim in sunlight that it is useless. I noticed that my phone is the same. If I cover everything that looks like a light sensor to make it think it is in the dark, the screen gets much brighter. If I shine a flaslight on it, the screen gets very dim. Both of us have Android phones, so we asked another coworker to check her Apply phone. It behaves the same way. In the dark, it gets brighter and in bright light it gets dimmer. All of us think that this is backwards. Shouldn't it get dim in the dark and bright in the light? Is there a way to fix this other than turning off auto-brightness and setting it my hand every time you need it changed? 97.82.165.112 (talk) 19:04, 17 February 2023 (UTC)
 * This has instructions on how to turn the feature off. This is called "adaptive brightness" on Android phones.  -- Jayron 32 19:07, 17 February 2023 (UTC)
 * As described here, the idea behind auto-brightness is that the display will be dimmed in a dark environment and made bright in direct light. --Lambiam 21:18, 17 February 2023 (UTC)
 * It seems that Android phones attempt to learn your preferences, so maybe if you continually turn the slider down in the dark and up in the light (with adaptive brightness turned on at the same time) it will eventually catch your drift. I'm not sure why it would be backward in the first place, or why this would be commonplace. Card Zero  (talk) 18:39, 18 February 2023 (UTC)
 * My Apple phone does the opposite - dims in darkness and turns full-on bright in daylight. Ive got everything set to automatic that can be. :-) BluSwedeShu (talk) 02:27, 21 February 2023 (UTC)
