Lightflow

Seen reports of people saying Lightflow messes with Ambient Display. Can anyone confirm this?

This should be in Q&A section. Anyway, I have both Ambient Display and Light Flow on. Light Flow does not mess with AD, and works quite well with it. Light flow colors work. I have the Pro version of Light Flow.

Sorry, the question is about an app so I thought goes here? Anyway. How does your AB work? Does it pulse randomly (like Moto X) or only when lifted or notification?

I used light flow pro and it forced screen wakes for a few minutes without a notification being present then it calms down. I uninstalled it and ambient display stays off unless there is a notification

Got it. Without Lightflow, there are only 3-4 pulses. With, it never ends.

Ah, I noticed that too but hadn't put that down to Light Flow.
I have a GWR, so disabled Ambient Display anyway.
Has anyone got the Sleep function to work?
No matter what Light Flow settings I use - at night, the LED continues to light up my room, so I have to leave the phone face-down at the moment...
I've been emailing the developer about it - but he's waiting for his 5X to turn up (as he's also ordered a 6P, he has to wait for that to turn up in the same delivery...)

I have enabled notification light through Settings and am able to generate a white light flash (repeating) when gmail receives. Has anyone noted fingerprint security have any negative impacts on notifications like this (more curiosity than anything)?
Admittedly its been some time since I have had to use lightflow pro; good app, just been awhile so I may be rusty on settings I am betting.

Lightflow is one of my standard apps. Unfortunately, it was draining my battery on the 5x regardless of the settings I had set. Looking forward to an update after the dev can optimize for MM/5X/6P.

Anyone else having an issue with lightflow and mms alerts needing to be cleared manually in the app?

To anyone who has Lightflow pro running well: would you mind posting your settings?
I've tried every combination I can think of: root mode on/off, run every command as root on/off, etc. The best the app can manage is a brief pulse on, then off, then a quick on/off before the LED stays off. Have tried direct mode, too. Tried the Legacy version, but it doesn't cover a lot of apps.
I can't seem to get any consistent results otherwise.

Just as a note: I looked at their website, and tried installing the Legacy version without uninstalling the paid version. All apps show. Legacy version works fine.

Yes! I just got the 5x and am settling down with stock Android for a while. Rooted and Xposed. It will be maybe 2-3 days before I start installing custom ROMs! Thanks for the headsup on this particular ROM!

I have only had it for one night but it seemed to work fine for me. I changed the sleep method to "time" (it defaults to NFC or something) and set the "start time" to 10:30pm and the "end time" to 6:00AM. I also have ambient display disabled. I am not sure what GWR is though. Also make sure in each app notification setting you do not have "exclude from sleep mode" checked.

I'm using paid version of LF. For now I'm not rooted.
I noticed behaviour you've already talked about.
1. If I'm using ambient screen I always have notifiction icon "Number of notifications". Can I hide that?
I know I can hide it if I disable app notification, but in that case Light flow don't work anymore ...
2. Is there any solution with messing ambient screen and LW led. After recieved notification ambient lights on few times and completely mess up LF ...
Is Legacy version solving those problems?
Thank you.
edit: I solved problem with legacy.

I have en issue with lighflow legacy that when I set my gmail notification to switch screen on, it won't play the notification sound correctly, the screen will light and notification sound is not completed when email is received, it is like once the screen switch on, the notification sound won't complete till the end. Anyone noticed that? disabling switch screen on, will make the notification sound fine.

I have this problem with a N5x and LightFlow.
It doesnt matter if I do use Lightflow normal or legacy, because on legacy I kept seeing a Lightflow notification and the screen turns on with ambient display continuously due to this :S

Screen is not white.

I have my note 10 next to my note 8 and the 10 screen is not very white compared to my N8.
Anyone else notice or know how to fix it?

Make sure the blue light filter isn't on

Could be the blue light filter or screen temperature and/or screen mode.

Go under Display then Screen Mode and change it from Natural to Vivid. That should brighten your whites a lot more.

My blue light filter is off. But for some reason while using Vivid screen mode, the screen becomes more and more yellow after 6PM. On natural this doesn't happen.
Has any one observed this strange behaviour?

It's the panel it seems Samsung have adopted a less whiter or warmer(?) one this time round, as all note 10 pluses I've held mine next to at stores etc are the same. My one plus 7 Pro is considerably whiter...

It's not a bad thing, I can assure you most Note 10/10+ have different screen calibration.
I have 3 S10 5G and the white looks different on all of them, lol. As a matter of fact even the native ONE UI dark mode looks different on all 3 units as well

This is clearly not a calibration issue. As I said this happens only in the evening time as if blue filter kicks in eventhough the filter is off. During day time the screen is white as usual.

Mine gets warmer when I go into Moon Reader Pro., its nice and cool white everywhere else on the phone And before anyone asks, yes BOTH blue light filters in the phone settings AND the moon reader settings are OFF.
I read somewhere that some people fixed it by going into Google books and apparently the blue light filter is turned on there and affects other apps. Dunno how much thats helpful since I didn't have G Books installed and when I did install it, the option was off but oh well

Checked that too. It is off there as well...

Hi there,
I was also wondering if there is another way (than the native tool) to adjust color temperature to set perfect white

Settings» Display»screen mode» vivd» move slider a little bit to the cooler side. Then go to advanced settings: turn down red, set green to about half and leave blue at full. Or adjust to your liking.
I've been making these adjustments since the note 8 but the note 10 seems more on the red side than normal.

Just did a factory reset, and this issue is gone. Probably something wierd happened while restoring from Note 9 backup.
Sent from my GM1917 using Tapatalk

I had this issue too, at 8:30pm, and it affected Google Photos and Samsung Gallery.
I had a OnePlus3 and had the bluelight filter set to 8:30pm.
My fix was to go into Google Books, open a book, click on Aa and turn off the filter. I never use Play Books, so it was very perplexing.
Therefore, I'm convinced this is a hidden Android system setting that is no longer accessible and carried over from the Android restore process. I'm happy to be rid of the problem though.

You were right. I just downloaded the Play books and found out that night mode was set to "automatically".

It is a well known fact that restoring from an older or former device often results in certain conflicts, as the settings and other componets are different between devices, this I've heard since my note 3 days

Green hue on bottom half of screen

See attached image.
I've noticed a greenish hue on the bottom half of the screen. It's most visible at low brightness and greyish/darkmode backgrounds. Not visible on amoled-black backgrounds. Present both in 120hz and 60hz, and both vivid and natural screen mode. Intrusive enough that I notice it several times a day.
Anyone else have this problem? Is it software or hardware-related?

YES!!! I've had this problem since getting my S20 Regular on Saturday. I got this replaced from the store yesterday, and the new phone has similar issue, although it's not that apparent. What I also see is that in Light mode, the white is warmer at the top and cooler at the bottom. These hues are just inconsistent across the system, be it the Settings menu or different apps. Here's everything I've done to eliminate the issue but failed:
Cycle through all combinations of resolution+refresh rate
Switch between Natural and Vivid colour settings, including changing colour temperature
Turned off Adaptive colour filter from Dark mode settings
Disabled 'Use sRGB picture colour mode from Developer options
Force Dark mode from Developer options
Simulated Monochromacy
Performed Factory reset
Got the OS reinstalled at the Samsung service center
Apps in which I was able to see this issue in:
Most system apps like Settings, Messages, Dialer, etc.
Discord (especially in the channel menu)
Falcon Pro (Twitter app)
Gmail
WhatsApp
Telegram
Reddit sidebar
Gboard (dark themes with Key borders on)
Apps where this isn't an issue
Twitter
Discord (AMOLED mode. This doesn't change the side menu which is still grey)
I'm attaching pictures comparing my first S20 with an M30s that also has a sAMOLED screen. The green hue is visible in the dialer app in the first pic, and how this green hue distorts greys is visible in the 2nd pic in the hamburger menu. The S20 becomes lighter towards the bottom whereas the M30s remains consistent for the most part.
My current S20 doesn't show this behavior in the Dialer app (it mostly seems pitch black) but in the other apps, I can marginally make out inconsistency, and in this case it becomes lighter from the right of the screen to the left. Even in Gboard with a true dark theme, some of the keys appear lighter than others because of this.
I'm gonna try to get this replaced from the store tomorrow, but good to know that someone else is facing the same issue.

Had the same problem. It was really annoying. Every gray background had a strange green hue. You can also some a hue on other colors, but it’s not turning into green in all situations.

Yes, also on Ultras and plus. I returned the ultra because of it and got a plus. It is a lot more bearable but I have to confess that I ordered another Plus to see if it is better.

Did you get yours replaced?

I thought I could live with it but it is also getting extremely annoying on dark backgrounds that I had to turn off dark mode indefinitely. I think I'm gonna fight with Samsung to try to get a screen replacement at least (in a couple months when they get their shiet together) since it is not acceptable on a $1400 phone. I should have waited before selling my note 10+

Having the same problem on the top half of the screen
Galaxy s20, exynos

So I just had a new software update (ATCH), and I'm happy to say this issue now seems much less pronounced! Still a slight discoloration under specific conditions, but definitely a significant reduction.

I can not confirm, that ATCH is making it any better on any of the devices I tried (Ultra, 2*plus). It made no difference at all, IMO.

Same here, no difference after the update. Clearly a hardware issue unfortunately, otherwise all phones would have the green tint in the same spot

I might a spoken too soon, as once I enable "blue light filter" the problem returns full strength. Though the update has made certain backgrounds true amoled black (such as in settings and dialer), which reduces the problem in these apps.

Yes, I haven't noticed any change with this update, which I installed 5 days ago.

Hello, Yes i noted it from first date. It was clearly visible in Phone, Messages, Notification centre and settings app and every Google app in dark mode. After last update it's OK, but for example Samsung Health or Feedly side menu it's horrible. Unfortunately Samsung store is closed because od quarantine.

It's apparently an issue with the devices manufactured on February-earlier. Most of the S20 devices made in March do not have the issue or have a less exacerbated green tint.

On number 5 I can say that it is finally bearable. It was manufactured on the second of march. I did not check with the rest. I only opened them, handled them delicately and checked them. All were terrible.

is this the problem with s20 exynos or s20 sd865?

Personally, I can only talk about Exynos. I would, however, suppose that it is through all kinds.

Auto brightnes failure after Android 10 update

Hi,
mine Redmi Note 8 PRO worked well until the Android 10 OTA upgrade.
After it autobrightnes does not work well anymore.
At some point it simply drops to very low level and wont change regardles the light density. Either being dark or very sunny it will simply be at level of about 10%.
If i reboo the fone autobrightnes will start work again. At some point idk wich it simply stops.
Anyone with same isue and posible fix?

I encounter the same problem sir. Been searching for a while. Hoping that there is a fix.

That sounds annoying, but I have not experienced it (Global version).
I hope somebody with an "inside" connection to Xiaomi is collecting and reporting this and other bugs.
I know there is a "Mi Community" forum, but the last time I looked at it, it seemed mostly like advertising.

Ok, after reeboot sensor works fine again. I can confirm nearly 100% that it got messed up with playing a game. Also Roaming data does the same. It switches OFF. Then i reebot and switch it back on it stays until sensor brakes. Then reboot again. Damn.

Same here

I too face same problem.
I too face similar problem, I'm using global version. I had updated to latest version. Now MIUI 11 with Android 10. Now i manually adjust screen brightness. Every time i restart the device its working, but once it goes to low brightness it won't auto adjust again.
I saw some post in reddit. It says it may be because of AI. Not sure, any MIUI insiders please take note, also fix it in next update.

My Global Version works fine.
In a dark area the brightness is low, pull down the status bar to check, Walk into a bright area and the screen gets brighter, check status bar, Then walk back into a dark are and the display goes dark, No Problems and it`s been a week since i last rebooted.

If you want to try..
Back up first data which is important..
Then wipe all data in recovery 3.0 menu
This metode will delete all apps you have installed and delete all data photo etc..
If its not fixed auto brightness sensor

Removing THEM APP does not help.

Same here, the auto brightness is no longer working. It defaults to either a very dim or very bright setting. Rebooting resolves the issue temporarily but the it reverts back.
Uninstalling the Themes app updates does not seem to resolve the issue but I'll keep an eye on that.

I don't game on the phone either. It used to work fine until the latest update I think (MIUI version 11.03.0 (QGGEUXM)).
Although, it could've started with update to Android 10 (11.02.0) and I didn't notice!
What version are you on?

One more thing I'd like to check. There was a mention of uninstalling the Themes app updaes. I tried that, and at first it didn't seem to make a difference. However, since I rebooted the auto brightness seems to have been working for nearly a week but not sure if it will last!
Can you please confirm the version of the Themes app on your phone.

Question Poco F3 yellowish screen

The whites looks yellowish, like warmer tone. reading mode is off. I got phone this yesterday.
MIUI Global 12.5.6
My last phone was Redmi K30, and this is my first amoled sceen phone.

Was it like that out of the box?
If so it may be a firmware or hardware issue.
If not, 3rd party app like a book reader.

Is "Adaptive Colors" off in Color Scheme Settings?
If yes.. maybe refund/replace your phone, if it's a hardware problem...

Can you take a picture of the device showing the yellow tint? It definitely doesn't sound normal, but could be a software issue

the picture can't show the issue, but it is like you set the color temperature to warm or turning on night light/reading mode.

it is off. temperature is at default, and setting it to cool didn't fix it either. I guess I'll ask for a replacement.

If you are talking about white looking yellowish; here's what to do:
1- Go to settings > display > colour scheme
2 - Choose advanced settings
3 - Choose enhanced
4- Go to R (red) set it to about 75% and G (green) to 75% as well - Leave blue at a 100%
5- Reduce both value and contrast by about 5-10% ( just a lite slide )
6- Set Gamma to 0% ( slide it all the way to the left)
7- Save changed and report back the difference.

It's 6am, and screen is slowly reducing the yellow tint. look like this have scheduled reading mode, even though I have it disabled.

Turns out the night mode configuration was from my previous device and restored by google to my new poco f3.
I used SystemUI Tuner to disable the hidden night mode settings.

Hi! I got my Poco F3 yesterday and currently encountering the same problem. I've already downloaded SystemUI tuner and enabled ADB. But where can I turn off this hidden night mode?

Unbelievable, it's really better, white is white.
I just bought this phone, is it a hardware defect ? (should I return it?)

I had this problem too, what @azeunkn0wn suggested worked for me (when the screen turned yellow at night)
Without root:
1. Enable ADB like this in the developer option
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2. Reboot the phone to apply the changes
3. Disable night display option with the commands:
- adb shell settings put secure night_display_activated 0
- adb shell settings put secure night_display_auto_mode 0
4. Reboot the phone to apply the changes
And it should be good
Note: if it doesn't work, check also:
Settings - Accessibility - Vision - Color correction - Off

I didn't return mine, tweaking it made a huge difference and am happy with it.
