BND-L24 Screen Dims slightly in apps. - Honor 7X Questions & Answers

So, I notice that when I get int apps, and go to the home screen, the screen gets brighter, meaning the apps are dimming the screen ever so slightly, any fix? I've noticed it the most in Chrome, but it happens in many apps.

Yes, that's been noticed by many of us, with varying levels of irritation. I believe that if your brightness is set to "Auto", you won't see the dimming, but I'm not crazy about how the Auto mode works. I should confess that until someone else called attention to it, I never noticed the slight dimming myself, so I won't get too puffed up with outrage.

I have also noticed this. The screen suddenly gets dim while using some apps (mostly Chrome). When I press the home button, the screen brightenes up to its set brightness. Also, I have auto brightness turned off. So, this shouldn't be happening. Currently the only fix is to exit to the home screen.

screen dims/brightens when I scroll

I notice this in opera, and today in the facebook app too, and was really baffled. The effect is quite subtle, but repeatable. When moving my finger around the screen, eg on the bbc news website panning to the top left, my screen dims. It stays dim when I remove my finger, and brightens again when I pan back down to the right.
Weird, huh?
So far it's just a curiosity and not an annoyance. Has anyone else seen this?
So I am not the only one who noticed this. I sometimes find this behaviour a bit annoying, especially in low light.
The phone has an ambient light sensor. It is adjusting because you are causing a shadow over it.
You can probably turn it off
Under the power settings/backlight - auto adjust backlight. Just uncheck it.
Any idea where the sensor is located?
Do you really think it is the ambient/light sensor? I sure don't. Scrolling through different websites I can easily reproduce this:
You scroll from one point to another, this just has to be a couple of pixels, and the screen adjusts the brightness. That is within a room with a fixed source of light and I am keeping my body as constant as possible to avoid the shadowing.
Scrolling from point A to point B makes the backlight adjust itself, even without casting any shadows or similar. Scrolling back from B to A makes the backlight instantly adjust itself back.
It's your finger causing the shadow, not your body. If you introduce an object into an ambient light source, you will find that said object will reduce the ambient light by a percentage due to partial or total obstruction. The light sensor is detecting this percentage and adjusting the screen accordingly.
The sensor itself is somewhere near the speaker.
I'm pretty sure this doen't have anything to do with the light sensor UNLESS it's cause by the screen itself becoming brighter and this registering on the light sensor, eg internal light leak.
My best guess is that it's connected to the presence/absence of certain colours on the screen, and is related to the video driver. Next time I get it I'll see if I can reproduce when scrolling via the kbd, to eliminate the theories about casting shadows on the screen.
This is not FINGER SHADOW!!!
You can notice this same thing when you plaing Solitare cards and using Stylus.
I'm sure i did't do any shadows and anyway when i pick up any card and moving aroud screen u can notice screen brighting up and down.
Using Opera 9.5, on this site http://game-board.blogspot.com/2008/05/alternative-monopoly-rules-and-game.html zoom in with double-click, scroll about half way down to the paragraph beginning "property has too much pollution on it", then scroll up and down and notice the change in screen brightness. please post if you can repeat. it does not work with the keyboard.
btw, does anyone know monopoly "bloodbath" alternative rules?
I've noticed my screen doing this without causing any shadows & without even touching the screen at all, like a 'breathing effect' when it is completely idle. I think it has something to do with light sensor polling interval which is editable via the registry, advance config and HD tweak...but since I flashed NRGZ ROM (21/08/09 build) this issue has gone anyway.

Screen flicker test

Hello. Since getting my new HTC M8 the other day I noticed that the screen can flicker for a fraction of a second when in the setting menu.
The issue really comes to light when you use a screen filter, I use the app that is literally called screen filter. If you set the app to about 20% and then you go into the settings menu you start seeing microsecond white flashes when backing out of and entering new menus.
Does anyone else experience screen flicker on there M8. I like to know if its my phone thats the problem or the screen filter app. If someone wouldnt mind testing my steps above out, it also helps if you have the screen filter on in a dark room as the flashes become even more pronounced.
Thanks

Does everyone's screen auto dim?

I have auto dimness unchecked, and whenever the brightness is set to over 55%, after unlocking the phone it always auto dims byitself.
Is this normal? no other phone does this. Can this be bypassed somehow? It's jarring when you unlock and see a bright vibrant screen and all of a sudden it dims like 10% or so after 5 seconds.
Phone auto dims when it starts to heat up regardless of your settings.
Otherwise it shouldn't as long as it's not set to auto brightness.

Ok, but when the phone hasn't been used in 30 minutes, and not "hot" at all, this still happens. This also happened with the G3 as well.
Is there a way to turn this off? This post has over 100 views, can everyone please comment if their screen does the same thing? Are there any solutions?
What carrier/model do you have?
I just tried this on mine, Verizon, 611A software.
With Auto Brightness disabled, set to 40%, I powered off, turned it on, then unlocked. The brightness did not change. Then set it to 100% brightness (Auto still disabled), and did the same thing. Again, the brightness did not change.
I have, however, seen the screen brightness reduced when I'm using Auto Brightness. If I turned it off in a bright area, then unlock it in a dim area, the screen will be bright for a moment, then will turn itself down, presumably based on evaluating the current ambient brightness.

auto brightness is always off. It's the AT&T non rooted stock version. I just tuned brightness to 70%, powered off, powered on, and after unlocking and opening chrome it auto dimmed within 5 seconds.
Does it do it if you don't open Chrome?
I've seen apps make their own brightness adjustments (like a camera app that maxes out the screen brightness when it starts up). I want to say that Chrome (on my last phone) is one of them. Alternately, turn it on, unlock, wait 15 seconds, THEN start Chrome. If it still happens right after Chrome loads, then it's a Chrome phenomenon, not a just-turned-on phenomenon., and at least you can isolate what to chase down.

Yes it dims even if I don't use chrome. No matter whats on the screen it dims a little after 5 seconds.

Download LUX (couple of bucks) set it to manual, 100% brightness on all LUX setting areas and it will bypass LG's lame attempt to hide the fact that they can't make a phone that doesn't suffer severe battery drain and overheating.
Your problem is called High Tempurate Thermal Mitigation (throttling). I depise it but with LUX, I tell the phone what is acceptable to me, not the other way around.
If I wanted to be dictated to like a submissive I'd just get an iphone.
I don't doubt that excess temps can cause the phone to adjust its behavior. But that quickly after turning the screen on? That seems really fast for something to go over-temperature, and for a sensor to also detect it that quickly. You may be 100% right, it's just not something I'd expect to happen that quickly.
This is a serious suggestion, despite how it may sound What if you put the phone in the fridge for 15 minutes or so, then do the same test? Does the screen still dim after 5 seconds? Depending on the humidity level, the phone could start to condense after coming out of a cold environment, so use your best judgement.
For a "safer" test, hold it in front of an air conditioner for a few minutes, with the screen off. Then, still at the A/C, turn the screen on, and see if it immediately dims.
If it suddenly runs for a while before dimming, then I'd agree it's likely temperature-related. If it still behaves the same way, then perhaps it's a different cause.
Either way, Lux sounds like a nice addition to these phones, from everything I've read. I've just been too cheap to try it yet But the rather coarse auto-brightness from LG has me curious.

Have you tried the cool-down suggestions (fridge, A/C,) ?
Try installing ThermoCF to monitor the battery temperature. I find that when used for GPS (mounted on windshield) the screen will dim with direct sunlight. The temperature is in excess of 120 °F when this happens.
I just left the G4 screen on 50% brightness for about 5 minutes and the temperature remained 98 °F (this is on a wireless charger, next to a warm laptop fan exhaust). I switched to 100% brightness and the battery temperature increased to 100 °F over the next five minutes but no dimming has occurred. After a few more minutes the temperature dropped to 99 °F with the screen remaining at 100% brightness.
Different from your problem but: I turned on the developer options and set the screen to "always-on when charging" and have noticed that the screen dims after some amount of time (I haven't timed, maybe 15 minutes or so). I ended up here because I was looking for a way to change that time and may download the LUX app to do it.
Nice to know I am not the only one having this problem. I use my phone to play Ingress and sucks the battery dry faster than anything. The screen kept going dim as I was charging.
I also have this same issue on my G5. I've tried the Lux, free version, and it still dimmed on its own. I wonder if the paid version will help out my situation?

I like the auto-dim, and my phone seems to accept manual "guidance" as to how I prefer the auto-dim to work.
What I mean is that I can manually bump up the brightness slider (while auto-dim is checked/enabled), and the phone will auto-dim using the brighter setting. Or, I can bump the brightness slider down, and auto-dim will remember that and adjust the brightness.
So it's like you can control the baseline setting for auto-dim by using the brightness slider with auto-dim enabled, and then the phone will auto adjust from that baseline. I play ingress and during the day I bump up the slider, but during the night play I'll decrease the slider and still enjoy auto dim both ways, and preserve the most battery that way.
Aint looked to see if g4 has got it. I know g3 you go into hidden menu. And turn the thermal mitigations on and it stopped the throttle down. Lg has an insanley low throttle down temp.

On the g3 and g4 its under main hiden menu. I use shortcutmaster to get to them all. But the g4 the options not there. Im not sure i dont know anything about the g5. Im not interested in it at all. I am selling my g4. So i can get another g3.
Now i know theres an app 3ctoolbox. And in cpu settings you can modify the unclock temps i dont know if it does the screen.
So, the hidden menu in Marshmallow, here it is folks. Where would I be able to find the option to turn off screen dim do to thermal mitigation? Anyone have any ideas?

Mine also started to auto dim with auto brightness off. I have the H812 from Bell . I'm sure that on mine it's the proximity light sensor that is faulty or in the software. Because when i turn on the phone while blocking completely the proximity sensor it doesn't dim anymore. (knock knock doesn't work while sensor is blocked) but problem comes back if i wake up the phone without blocking the sensor. I have tried it many times and it's the same thing over and over.
Calibration in the hidden menu doesn't fix it, Lux and many other brightness apps iv'e tried don't fix the problem lol
I also use lux with cf.lumen
Lux will manage the auto brightness as per your preferences because i found the stock LG screen was about 15% lower than id like in all environments.
Cf.lumen actually changes the colour of the display rather than applying a dumb screen filter on top for night viewing.
The only thing Lux does for me is dim the screen twice since the phone already dims by itself 3-4 seconds after the screen is turned on. I can guaranty it's not an overheating problem, even after 30 minutes in the fridge it does it. I'm tempted to have the proximity sensor changed but will most likely wait for LG to release 6.0.1 to see if it will fix it.
Nougat 7.0 is days away and still no 6.0.1 MM for the G4. Pardon my language but LG really sucks . This is my first and last LG phone

Backlight Flickering

Guys how are you doing? I'm having a strange issue with my phone, i've searched the forum about it but couldn't find anything about it other than a couple of messages without any conclusion. This problem is mostly noticeable when having the screen in minimum brightness, it's like the backlight flickers a bit. If writing an SMS for example, whenever you press a keyboard key the screen flickers (it's very faint but noticeable). Also, when you open any app, it's like the brightness goes up a bit and down again, it's a very strange issue. Is anyone having this problem? Seems to be a software glitch because if you leave the phone in a static screen, that doesn't happen. It's updated to the latest fw version btw, it always happened.
To make it clear (and if anyone wants to try it), this happens with auto brightness, and the slider set to the minimum in a dark condition, whenever the brightness is medium/high at least i can't notice it.

Question Screen Brightness

I've had my Z Fold now for about a month and I've been noticing an odd fluctuation in brightness. I've made sure that the auto brightness option as well as eye vision comfort are disabled. I still seem to get random drops in brightness even with those turned off. Is that something that just happens with this being a AMOLED display? For instance today I was on my messaging app. I was watching the brightness in real time drop and then go back up. Drop and then go back up. I've never noticed that with other phones. Any help or explanation would be appreciated.
I have noticed this too and thought it was me. It is not due to overheating because it happends in browsing, mails and just viewing the gallery. I have all screen related adjustment set to manual or locked.
