    Hi guys,

    I recently upgraded my S6 edge+ to a s7 edge.

    On both the s6 edge+ and s7 edge I have experienced brightness issues. I do not have auto brightness selected and have brightness to max. It constantly will dim the phone based on the light hitting the sensor. It's like samsung's built in adaptive brightness. I have looked all across the internet for a fix to no avail, so am posting to try and see if I can get help.

    Some people might think "what's the big deal", but it really frustrates me. I might be OCD or something, but I hate when it will dim the screen without any input from me. I like to get the best viewing experience out of my device. I don't know why Samsung decided to add a built in auto brightness feature that cannot be turned off, changed, or toggled. Many users have experienced this and complained as I have seen in previous posts from other forums or in this one, because it is a persistent issue. The best that i've seen in terms of getting it fixed was a post a while back about a specific file you could replace in the samsung s6 edge+ to edit the code, or w.e in order to disable this function.

    Oh, and no, it is not some issue that can be fixed by changing settings already on the phone, I am 99% sure of that.

    So I really need help. This is a big issue for me, regardless of how miniscule it might seem.

    I bought an $800 premium phone, one if not the best on the market. So when there is a built-in feature from Samsung that is constantly changing the screen view on it's own and is unchangeable, it's frustrating.

    My phone does not do what you say. When I turn off auto brightness it stays bright and does not dim. You should return the phone and get another one.

    It's annoying to me that auto brightness has a higher max brightness than non-auto. This results in higher max brightness for a while but then auto brightness kicks in and the screen dims. Maybe that's what you mean?

    I had the same maddening problem on my s6 too even after exchanging it twice. Same with the 7 edge. Why do I have to deal with constant brightness adjusting when I dont want it to? I think everyone has it, they just dont notice. I have an ipad and never do I worry about it changing brightness levels. There is a reason for having the option to not have it adjust so it should work! I have tried brightness programs but they dont work either.

    And actually mine dims without even light hitting the sensor. Its just random, although I find it happens more when I am texting.

    No, its not what he means. We bring brightness to the max, uncheck automatic ...then it randomly dims.

    No, I don't have this problem. Tried to replicate it for about 5 minutes and then gave up. So you can't say that everybody has it or more people would complain about it.

    Max brightness with auto off is not as bright as max brightness with it on. So yes you see it dim when you uncheck auto.

    DisplayMate: "More importantly, on the Galaxy S7 the Maximum Brightness can go much higher when Automatic Brightness is turned On, so that users can’t permanently park the Manual Brightness slider to very high values, which would run down the battery quickly. High Screen Brightness is only needed for High Ambient Light, so turning Automatic Brightness On will provide better high ambient light screen visibility and also longer battery running time."

    In Settings / Display do you have Adaptive display set? If so, try one of the other options and see if that makes a difference.

    Interesting. So you think clicking "automatic" while bringing it to highest brightness will maintain the brightness without adjusting it for you? Wouldnt it make sense for it to hold its brightness when unchecking it? Every phone I have ever had except the s6 and s7 has never dimmed while I was using it.

    This does not happen on mine. Set to manual and it stays. Set to auto and it adjusts to ambient lighting.

    Also, how can you stand using max brightness all the time? Do you realize how bad that is for your eyes?

    The Gaming Mode seems to occasionally do this on mine. Open an app, it detects is as a game and the screen dips. It's definitely that for me as I don't see it any other time.

    Can you narrow your issue down to anything like this.

    That explains it then. I never have smart stay on as it never worked for me no matter what Samsung device I have had over the years.

    Sadly, that didnt help. Same problem. Frustrating and really takes some of the pleasure away from using it.

    I have the exact same issue with my S7 and S7 Edge. They both will dim the whites on screens like settings, etc. This is with auto brightness off, and brightness at half way. But it will get bright again if I exit that screen then go back to it. Very strange. Its kind of like the dim that happens right before the screen turns off, but happens no matter what. Ive also got smart stay off, and tried other display settings like amoled cinema and it still happens of both phones. I think its some kind of battery saving thing, not sure though.

    The issue i dont like is that with auto bright off theres not much brightening past the halfway point on the slider. Dragging the slider from the very low point to mid point on slider there is definitely a noticeable change in the level of brightness but sliding it past the halfway point theres very little change in brightness level at all.

    Yeah, mine does the same even with all the extra display features shut off. Mine has been dimming in sunlight so much that I can barely see the screen. It doesn't dim when it's dark and during the day when I go from outside to in, it will get brighter. I have made sure that the auto brightness is of and the smart stay as well as I use the amoled cinematic for display type.

    I have the exact opposite problem, my S7 has auto brightness checked, and doesn't ever change on "occasion"... Not all the time. Like in a really dark room won't dim, right on the home screen, not in any specific app. Once I uncheck and recheck auto brightness, it goes dimmer.

    Anyone else having this issue? If so, do you know how to fix it? Just a slight annoyance.

    For those who don't experience this issue. It only is noticeable when you are consistently going from a extremely bright situation to a fairly dark situation. Typically of you go from the bright sun to shade. It will automatically darken the screen. Making it nearly impossible to see anything. I did not have this problem originally, but now that I'm outside a lot for work I have noticed the change. Auto brightness is turned off. Screen brightness is on the highest and yet it's extremely dim. The effects only happen when I'm outside, when it is still bright out but I'm in a lower light area. Anyways that is my experience.

    I've noticed that in direct sunlight, on auto brightness, it goes real high (I'll call it turbo brightness) as the Anandtech site mentions, but then after a few minutes, it'll reduce brightness down to 'regular max brightness'.
    I've tested it out, even takimg it out of direct sunlight for a couple minutes then returning it, where it went turbo again, but this time for even less time.
    I've concluded the issue is likely to be temperature related, because I did check the temp by hand and it was quite hot due to the warming effect of the direct sunlight. The second time I put the phone in sunlight, the phone was still warm from the earlier sun exposure, so ya I figure if the temp gets too high, there's internal protection to reduce power consumption and overheating of device, with one obvious way being to reduce brightness.

    This may or may not explain some of other people's issues here...

    Cheers
