I'm looking for software/mod to set screen white balance - General Questions and Answers

The only working as I expect is this app: https://play.google.com/store/apps/details?id=com.netmanslab.sa - but it's rather annoying, asks form ma gps location, it's bloated with ads and also changes are lost after reboot (I need to enable it again). And most annoying - it blocks possibility to install applications from apk file.
So do you know any mod/app etc to adjust white balance (RGB)? It should start with system, it should be invisible.

Yes, you could try this...
This allows you to set the White Balance, Tint and Brightness of your screen...

[Completed] Notifications on default lock screen

Hi,
I would like to make my phone's screen light up periodically when it's locked and I receive notifications.
My phone does not have a pulse notification LED and it does not have any other means of showing persistent alerts for notifications when the screen is locked.
I have sen many apps that replace the default lock screen and generally require a lot of permissions, change the lock screen design, wallpaper, unlocking method and mess up / complicate things unnecessarily in general.
What I had in mind is a very simple concept but I don't know if it exists or if it is possible, because it may consume too much battery or maybe Android just does not allow it.
I would like my regular lock screen (which already shows that I have notifications, by the way) to light up for ~1 second every ~1 minute when I have notifications. Ideally that would be customizable somewhere.
To save battery, if the front camera detects no light (i.e: the phone is in the pocket or turned down) then it would not light up the screen, assuming the camera does not consume more battery than this would.
Could someone help me find the closest thing to something like that?
Thanks.

May have found a solution for screen flickering at lower brightness

There is this app, which I do not own or have any affiliations with, that acts sort of like a filter that lowers the screen brightness instead of actually lowering it. I haven't really tested it fully, but it works perfectly on my s7 Edge.
And the best part is: there is no root required
All you have to do is to install the app, go to Settings - Accessibilty - Installed services - screen dimmer, and turn it on.
Just make sure that your actual brightness is at 100%, and you can change the brightness within the app, or with the shortcut in the notification bar.
Here is a link to the app:

Mi 10 Ultra Snapchat Issue

Hey all,
I have downloaded Snapchat on my Mi 10 Ultra. I am facing an issue with the friends list that I have. Everything in the app works great. But, when I try to send a photo or a video, the next page for selecting the names of people I want to send it to is in white and the names are in white too!! When I check any name it gets changed to blue and I could see who I selected. But, before that I couldn't see anything.
Side Note: I have enabled Dark Mode. Because, I do not like a bright phone. I am keeping this all the time. But, is it the thing that is causing the issue? How will I mitigate it?
Note: I have just tried changing to Light mode instead of Dark and all the names appeared without an issue. So, how do I get Snapchat to show names in other color other than Light grey and white in Dark mode so I can see them.
The problem is, that functionality of some apps gets broken when MIUI goes into Dark mode - it's more than a system theme, it forces dark mode onto apps as well.
For this reason, there's an option under Settings -> Display -> Dark mode -> (scroll down a bit to see the Advanced section) -> Individual apps.
There, tap the search bar if the app list doesn't come up at first and look for Snapchat, or whatever you need, and toggle dark mode off for this app.

Question True white?

My One Plus 9's screen's whites (e.g., on a white background web page) seem to be actually a bit off-white, like a very, very light gray. I took screenshots to make sure that #FFFFFF was being displayed.
I've tried playing with all the stock display settings but couldn't fix it. (I can make the very, very light gray look colder with the stock settings, but I can't make it be just white.)
I can fix it by pushing the white point to something around +0.10 with my ColorChanger app's custom mode option (root required), so I know the hardware can handle a whiter/brighter white, but I would like to be able to just set it with the system settings rather than having to make ColorChanger start on boot.
What display settings do you use in the advanced section under screen calibration?
Loose the color changer app. It can't begin to dial in the display. You can't do this by eye.
This smartphone should have excellent color rendering and white point. It's one of the best.
Make sure it's not a setting issue. Turn off Developer options for now and recheck all display and accessibility settings.
Either it's a software, firmware or hardware issue. If not running on it's stock rom start there. If already running stock, factory reset and be careful what apps you install.
-Or- find the app that caused it (preferred).
Book reading apps can alter white point settings permanently by altering hidden user settings. Uninstalling them sometimes doesn't undo the changes made by a poorly written app. Google Reader (I think it was that one) did this to me on my Note 10+. Had to reinstall it, change the setting in it, then uninstall the junk app once and for all... or factory reset
You get the idea.
Hmm. I thought I had tried all the advanced settings, but now I see that I can pretty much the same nice very bright white (and more neutral grays) by using the wide gamut settings as with my Color Changer. Don't know why I missed that. Should save a bit of battery life.

Question [GUIDE] Device Settings Menu | Part III - Display, Lock screen, Biometrics, Security, Safety

Device Settings Menu Guide, Tips & Discussions
Part 3 - Display, Lock screen, Biometrics and security, Safety
If you're new to this series or want to see the index, please read the Introductory Post first.​
Display
Dark mode settings: I have kept it 'Turn on as scheduled' with 'sunset to sunshine'. If scheduled, the dark mode is only enabled after the screen gets off.
Brightness: When you change brightness in 'Adaptive brightness' mode, your device is smart enough to learn your usage patterns to determine the best level according to the environment as per your preferences. 'Reset usage patterns' in case you think your phone is drunk when in Auto mode.
Motion Smoothness: You have a monster with a 120 Hz refresh rate! Use it with 'Adaptive' mode. It also saves battery keeping your refresh rates low when not needed. 'Standard' mode uses a constant 60 Hz refresh rate. Use it when you know you will be scrolling and watching movies but want to save battery.
Eye comfort shield [Formerly Blue light filter]: Learn why you should use it here. I've set it to 'Custom' > 'Turn on as scheduled' > 'Sunset to sunrise'. You can toggle it from the notification panel as well. Still need to see how the new 'Adaptive' mode works - it claims that it makes minor adjustments throughout the day. Anyone can comment?
Night Mode: (Pie update) Enable it to make use of true blacks on your AMOLED screen, save battery and put less strain on eyes. I know you want it to only enable at night, so hop up to developer mode and set 'Night mode' to Automatic.
Screen mode: I've set it to 'Vivid' to let Samsung be where it is best at - Display Vibrance! If you are towards the cooler or warmer side, you have now the option to customize with 'White balance'. In 'Advanced settings', you also get to tweak RGB colours!
Font size and style; Screen zoom: I've set 'Screen Zoom' to 'Small' and 'Font Size' to Level 2 in order to get more content in a screen view. Please tell me if there's any better font on Galaxy Apps.
Screen resolution: By default, you don't get the resolution enabled that your S22U is capable of. I've changed it to WQHD+ for getting the most out of the best display in the market. I've the resolution set to HD+ in Medium Battery Saver mode in case I'm on Survival mode.
Full screen apps: I customize it when needed for an app. You can tell which apps should not show your camera cutout (so they show a bar instead)!
Screen timeout: Mine is set to 10 minutes. You know, pro users!
Home screen: Self-explanatory and I use Nova Launcher. Do enable 'Quick-open' notification panel.
Edge panels: You can set a maximum of 9 panels. Explore options for each panel and try more of them from the Store. I've enabled Apps edge (also make app pair and folders), People edge (upto 10), Smart select (take portion screenshots, make screen GIFs, pin a screen's content), Clipboard edge (auto-categorizes items), Reminder, Device maintenance (useful to review device performance OTG), Tasks edge (explore all available tasks), Quick tools (must have), Calendar. Tap Menu and 'Reorder' the panels as per your needs. In 'Edge panel handle', I've set the Transparency to highest and Size and widht to larges. I've dragged the handle to Right near power button so that I can always guess where the handle is.
Navigation bar: You can enjoy the immersive display by setting 'Navigation type' to 'Swipe gestures' and disabling 'Gesture hints' and 'Show button to hide keyboard'. I eventually got used to this. You also have an option to go back by dragging the sides. You can use Nav bar button on Quick Settings by dragging down the notification panel to toggle showing the navbar then.
Accidental touch protection: Really useful because I keep my phone screen faced to my leg side when inside pocket so that it's protected from the outside cruel world.
Screensaver: In case phone is your life even when it wants to get charged peacefully.
Lock screen
Screen lock type: I use Pattern with Biometrics (Intelligent Scan and Fingerprints mostly Fingerprints only). Fingerprints remain the best security and battery-efficient method to date at least for me. Use Iris for more security than regular face recognition. Also, with Iris, your device won't get unlocked while you're sleeping or with your photo. Use 'Intelligent Scan' for bit more ease (read about it here).
Smart Lock: It's a Google feature that can unlock your phone via On-body detection, Trusted places/devices and Voice Match. I used it once with On-body detection but couldn't impress me. Read about it here.
Secure lock settings: Disabled 'Make pattern visible'. Set 'Lock automatically' to 15 seconds in case I want to turn on the screen immediately without unlocking it. Anyways, 'Lock instantly with power key ' is enabled when I explicitly want it to get locked. Use 'Auto factory reset' carefully as someone could initiate this by simply making incorrect attempts. I've enabled 'Lock network and security' especially for theft use-case.
Always On Display: For customizing it, go to 'Clock style' below. Guide on AOD here and video here. You now have new display mode as 'Tap to show' AOD for 30 seconds. I've set it to 'show as scheduled' such it doesn't glow when I sleep. Also, I get an idea that it's time to get to bed when AOD stops showing up (same for wakeup).
Clock style: You can customize AOD with different clock styles, pictures, GIFs, Calendar and roaming clocks. Blue 'colour' gives a soothing effect every time I look at the clock for me. Similarly, you can customize your Lock Screen clock style here.
Content to show: 'Home button and clock' feel elegant for me.
Auto brightness: If enabled, you can also change it by double tapping the AOD clock. I have set it to the maximum to get eyes on it!
Show always; Set schedule: If you often check the clock at night, you can enable the former. I've disabled AOD during my night sleep schedule so that I additionally get a hint when it's already time to go to bed and whether it's time to get up or not.
Turn off to save battery: Enabled. Do you need AOD in survival mode too?
Roaming clock: I had to disable it as every operator in India puts SIM to Roaming mode when you're out of your circle (mostly defined to a state) and I get two identical clocks whenever I travel out of state.
Widgets: Enabled all available choices and will decide about the reordering or need of each of them after I arrive at the use-cases. The same goes for you maybe.
Contact information: Do fill it. I've included my name and number on it. Can be useful when stolen, lost or misplaced. You can include email or alternative mobile numbers as well since the primary number would probably be in the device itself.
Notifications: I've changed it to 'Details' from 'Icon only' since later makes it similar to AOD style notifications and I want the description of notifications once I go over my AOD screen. 'Hide content' if you don't want people to read your notifications. I rather do this on a per-app basis (like messages for OTPs, sensitive apps). 'Notifications icons only' Toggle 'Transparency' if you find it difficult to read notification over the wallpaper or want your wallpaper to expose. 'Auto-reverse text colour' makes it easier to adapt with the wallpaper. You can define 'Where to show' your notifications here (AOD or Lock screen or both).
Shortcuts: Define the two shortcuts you see on the bottom screen corners while on lock screen. You can choose any app though default (phone and camera) works for me.
Biometrics and security
Biometrics: You can remove biometrics data and configure 'Samsung Pass' to use these here. You can enable 'Screen-on' scan for making the device scan for your face as soon as screen turns on. This increases brightness immediately while it's scanning (can be annoying) and will drain some battery. In 'Fingerprint Scanner', you can add as many as 4 fingerprints (reserve one for Secure Folder).
Screen transition effect: Disabled as I want things at fastest.
Google Play Protect: Enabled. Read more here.
Find My Mobile: 'Remote controls', 'Google location service' and 'Send last location' enabled. This should be the first things to review once you buy the device. Prepare yourself with a demo on findmymobile.samsung.com.
Security update: Shows the patch level and gets updated with 'Software Update'.
Samsung Pass: Saves your passwords, addresses and payment information securely.
Install Unknown Apps: Allow/Disallow existing apps to install apps from APK.
Secure Folder: The replacement for Samsung My Knox. Must-use feature to separate your very private and confidential part of the phone. Guide here and video here.
Private Share: You can share your photos and videos without letting anyone save or download it. Uses blockchain. Need to learn more about this.
Other security settings: 'Set up SIM card lock' disabled (same reason as in 'Secure startup'), 'Make passwords visible' disabled, 'Security policy updates' auto update enabled (Here is what are these), 'Send security reports' enabled. Set 'Device admin apps' with care (Learn about them here in case you haven't). You need to remove an app from here before uninstalling it. 'Creditial Storage' for CAs and user certificates (Learn more about CAs here). 'Pin windows' is a very useful feature for me. In cases where you need to give your device to someone (for like watching a movie or seeing the gallery), if this is enabled with 'ask for pattern before unpinning', when you 'pin' that app (video player or gallery), people will have to pass the lock method to get out of that app. Configure which apps can have 'Usage data access', 'Notification access' and 'Do not disturb permission'.
Privacy
All permissions; Permissions manager: Manage and view granular level permissions per app or apps per permission basis.
Controls and alerts: You can set if apps can have 'Camera access' or 'Microphone access'. Disabling this makes no installed app to access these - could be done when you are in spy mode. You can also get alerted when an app accesses your clipboard with 'alert when clipboard accessed'.
Samsung: You get the privacy policy in Samsung Privacy. In Customization Service, I have disabled Use mobile data to save my data against nothing important. You can also request to Download your data Samsung has collected about you.
Google: Just like above, see what Google collects!
Location
App permissions: Allow apps and sites to detect your device's location. I've enabled it since I use too much location-specific content. You can turn it off if you suspect your dad working in NSA (approx. locality can still be tracked through IP, use VPN). If you need to enable Location for an app, I suggest using Allow while using app than Allow all the time for apps that you think only needs to use while you are using the app. Why allow Instagram to get location all the time when you only need it while sharing something? Google Maps, on the other hand, can give you information about upcoming traffic if allowed in the background!
Wi-Fi scanning; Bluetooth scanning: Wi-Fi scanning uses the database of Wi-Fi locations to predict your location. Read how it works here. Similar goes for BT.
Safety and emergency
Fill your Medical Info like Blood group and conditions so that any help knows about this when life goes wrong.
Add your Emergency contacts so you can access them on lock screen.
You can enable DND while you are driving with Silence notifications while driving.
Emergency mode [Formerly Ultra power saving mode]: You get a black screen that enables you to call and text. Saves a great battery when you are in survival mode. You can add few apps like WhatsApp too!
Panic mode: Keep this enabled (can save you) and when you press your power key 3 times, your device sends Location, Emergency text and photos from your camera to your selected content. Be careful that you are likely to press the power button multiple times when you are stressed and you would be sending unwanted photos to your contacts. Either disable the photo-sharing option or select contacts carefully.
FAQs
Does having Adaptive Refresh Rate really work better with a battery instead of 60 Hz? (Asked by @brokyneo)
Ans: It depends on the usage. If you reading something and not watching dynamic content like videos, you don't need to refresh the screen 120 times a second!
Adaptive Refresh Rates on S22 Ultra has 7 rates: 10Hz, 24Hz, 30Hz, 48Hz, 60Hz, 96Hz and 120Hz. With 10 Hz, you essentially make the GPU display frames 92% fewer times! This should save your battery to a great extent!
