Do you use your phone a lot on constant brightness? Does this drain battery or strain your eyes? Here's an application which will help you get accustomed to lower screen brightness.
hxxp://play.google.com/store/apps/details?id=com.torcellite.smartscreen
Smart Screen reduces brightness gradually from two settings set by the user. You can also add a screen filter to it.
How to use the app:
To start, set a comfortable start brightness and a lower end brightness. You can see the previews.
Set by how many points the brightness should fall every cycle.
Set the cycle time in minutes. Minimum being minute.
Also apply a screen filter if using at night or if required.
Once complete, a notification will pop up allowing you to reset your brightness and disables the filter.
NOTE: ENABLE FILTER ONLY RIGHT BEFORE PRESSING START OR YOU CANNOT CUSTOMIZE THE TIME AND BRIGHTNESS REDUCTION POINTS.
You can also use the app as a dimmer. Just enable the filter and leave it. You dont have to press start. To disable, go to the app again and uncheck "Enable screen filter".
Example:
Start brightness : 200
End brightness : 100
Reduce brightess by: 15
Interval : 2m
So, the app will reduce brightness by 15 every two minutes from 200 to 100.
The screen filter is to add a shadow kind of effect.

I want an app to set a few things with auto brightness:
-High and low
-when it should change and how much
Is this possible?
How about this?

Check post 21 for screenshots. There are something like 3 different versions of it throughout the thread also.
More looking for something to extend the range of auto brightness, it currently only goes 25%-100%. Too bright in the dark.
It's always too dark. Any way to mod this? I don't really want to manually adjust, as that is tiresome.
Seemed to work better on my old p1000.

I did a kies update. Seems to be worse now. Too bright in the dark and too dark in the light. Also slow to react to light change. How difficult can it be for samsung to setup auto brightness. I actually think my old p1000 is a better tab in many ways apart from the 3d speeds..

I wonder if this is because of a low quality light sensor. My Motorola Atrix does a pretty good job of regulating brightness automatically, except even that one is still too bright in the darkness.
For now I just make manual adjustments to the brightness on the tab, but thankfully the adjustment slider is right there on the notifications pop up so it only takes a second or two to make an adjustment.
Yes I could do manual adjustments but when I go outside and it's very bright I can't see the screen and this is where auto brightness needs to work well, which it doesn't and it is far too slow to change when I really want to take a quick pic, it just fails as I can't see the camera app for about 5 seconds.

You may want to uncheck the auto adjust screen power box that is in Settings > Screen. I notice that tends to darken the screen as well, even with auto brightness disabled. Screen mode (dynamic, standard, movie) also affects the color temperature of the display which may give a darker tone. Try the different modes and see if that helps. I notice movie mode gives a warmer look to the screen where standard seems cooler.
well , are you using screen protector ? maybe its the cause ? anyways i don't really like to set it at auto as the HC brightness is SUCK in many ways ... i like to adjust it as i want .. so live with it until samsung do something .

Unchecking that box made a huge difference. Thanks.

New Auto Brightness App called Lux
There is a new app in the Android Market called "Lux Auto Brightness" (I am new here so cannot post links but just search the market for Lux) that is by far the best Auto Brightness App I have seen yet. It is hands down better than anything that comes with stock Android. I have installed it on my Tab 7.0 Plus and it pretty much solves all of the issues/complaints I had with the built-in Auto Brightness. I really love how you can change the preset backlight level (for any light condition) to one that works better for you and once changed, the app will use that backlight level instead of its preset. This is a paid App but only cost $1.02 and lets face it, $1.02 is a very small price to pay for Auto Screen Brightness that works (no, I am not the author of the app). If you are going to install it on your Tab Plus 7.0 just ensure that you turn off the built-in auto brightness as well as unchecking the "Auto adjust screen power" setting under the Android settings/screen menu. Below is the description of the App from the Android Market...
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
★FEATURES★
→ Custom auto brightness.
→ Sub-zero brightness to make reading in the dark significantly less irritating.
→ Battery efficient
→ Handy brightness widget
→ Option to use the camera to read in ambient light.
→ Power-user settings such as choice of interpolation, sensor debugging, and linked sample editing.
→ Backup to SD.
→ Customisable data filtering for phones with inaccurate light sensors.
→ Gradual fade effect for backlight adjustments.
→ Astronomer mode adds a red filter to the screen to preserve the eyesight of stargazers.
→ Jitter control to prevent constant small changes to the backlight.
→ Night mode, to change the colour temperature of the display for comfortable night time viewing.
→ Add app specific exceptions via compatibility mode
→ No ads, or other nuisances.
Note: Please disable other brightness apps before using Lux. This is still BETA software. The author is not responsible for any issues caused by using this app.
Useful app thanks.

I know they mean well, but I do not like being forced to use the new Adaptive Brightness (aka Auto Dim) feature and I cannot find a method to disable it.
I keep my display on a low brightness setting, usually a 3 or 4. When the Adaptive Brightness kicks in, the screen is too dim. The only way I can find to "correct" this is to set the brightness higher, much higher. A counter productive solution.
Is there another way to turn off, or disable this unwanted feature?
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:
https://play.google.com/store/apps/details?id=com.github.ericytsang.screenfilter.app.android
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!
