[Q] Auto brightness setting disappeared??

Always have had auto brightness on, it works for me.
But, after adding the 'power' widget to the homescreen (which can control brightness settings) and fooling with the brightness a few times, i decided i wanted it set back to auto.
Went into the menus, and there is no tick box for auto anymore, in the brightness setting. Just the slider.
Took the widget off the homescreen, no change. Rebooted, still no change.
What gives?? Anyone else have this happen?

EDIT: Solved problem. Was the LCD density, i guess it squashed the box and hid the setting.

the widgets on screens, usually cycles through the different modes
just keep cycling until you get it back
or simply go into Settings > Display > Brightness (make sure check mark is green)

That's the thing though - there is no check box anymore!!
Very curious as to how a system setting could just disappear like that.

Settings - display - brightness and there it is just above the slider on the lrft ?
Is here for me and I also have the brightness widget.

i think it might be JM5 firmware you are using
i'm using the official JH2

I can't help with the problem, but I can say that I'm running JM5 and have the "Automatic brightness adjustment" checkbox in the "Sound and display" settings.

wow, that makes it even more weird and intriguing....
how did the [OP] managed to lose that check box?

Wish i knew. And i want it back! Pretty sure all i did was add the 'power' widget, play with it for a bit, and it was gone.
I am quite certain it was working right after the JM5 flash, although to be completely honest i did not actually check. If it wasn't working i think i would have noticed rather quickly, its pretty obvious when its doing its job.
Added screenshots for the skeptics.

i'm not skeptic, i just can't figure out how can it has dissapeared on its own, yet i can't figure out which software could do something like that.
seems like worse case scenario is to reflash the ROM again to get it back

Was it there after you changed your font? Try the stock one.

Alright, i figured it out. Might add this over in the pertinent thread, too.
It was the LCD density setting. I guess it squashed the box down so much that the check box was entirely hidden! Man, what an odd problem.
Thanks for the help!

Wow, thanks for sharing
this is something worth being Noted on the Wiki
anyone got time to make an entry?

No problem, i'd add it myself if i knew where to put it...?

Thanks for posting the solution! I ran into the same problem and i was perplexed as to what happened.

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

Device Settings Menu Guide, Tips & Discussions
Part 3 - Display, Lock screen, Biometrics and security​
If you're new to this series or want to see the index, please read the Introductory Post first.​
Display
Auto brightness: When you change brightness in Auto 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.
Blue light filter: Learn why you should use it here. I've set it to 'Turn on as scheduled' > 'Sunset to sunrise'. You can toggle it from the notification panel as well.
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. I don't know why Samsung has put up such a useful mode here.
Screen mode: I've set it to 'Adaptive Display'. Do play with other modes and toggle them when needed. Customize 'Full screen colour balance' (and Advanced) when 'Adaptive Display' is enabled in case you don't like the default setup.
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 if there's any better font on Galaxy Apps.
Screen resolution: By default, you don't get the resolution enabled what your Note9 is capable of. I've changed it 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.
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 screen: Do you need a seperate guide for this? Or can anyone provide a link to one. If you use it right, this can make your life much simpler.
Edge panels: You can set a maximum of 9 panels. Explore options of 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 to smallest. I've dragged the handle to Right near power button so that I can always guess where the handle is.
Edge lighting: For me, it feels great to have it for some very important notifications that too 'when screen is off'. Do note that if you enable it for screen on as well, it will disable heads-up notifications. Play with 'Edge lighting style' as it shows the effect generated as you customize one. For me, {effect=basic, color=app_color, transparency=low, width=narrow} works. You can customize the lighting color for each app separately as well. In 'Manage notifications', you can define those apps for which you want this effect enabled.
Menu > Quick reply: Do define a reply because it can be useful in cases where you can't or don't prefer to type or check messages.
Navigation bar: I've enabled 'Hard press Home button' (great alternative to physical home button) and set the pressure to lightest (since I don't want to hurt my screen). With Pie, you can enjoy the immersive display by setting 'Navigation type' to 'Full screen gestures' and disabling 'Gesture hints'. I eventually got used to this. You can use Nav bar button on Quick Settings by dragging down the notification panel to toggle showing 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 or sometimes Fingerprints only). Fingerprints remain the best security and battery-efficient method till date atleast 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. With Pie, 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).
Content to show: 'Home button and clock' feel elegant for me.
Double tap Home button: Changed to 'Quick launch Camera' since I want it more often and I can turn on the screen by hard pressing anyways.
Auto brightness: Enabled. If you are okay with manually controlling this brightness less often by double tapping the AOD clock, disabling can save you some battery.
Show always; Set schedule: If you often check 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?
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.
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.
FaceWidgets: Enabled all available choices and will decide about the reordering or need of each of them after I arrive at the use-cases. Same goes for you maybe.
Contact information: Do fill it. I've include my name and number on it. Can be useful when stolen, lost or misplaced. You can include email or alternative mobile number as well since the primary number would probably be in the device itself.
Notifications: I've kept the defaults. 'Hide content' if you don't want people to read your notifications. I rather do this on per-app basis (like messages for OTPs, sensitive apps). 'Notifications icons only' makes it similar to AOD style notifications and I want description of notifications once I go over my AOD screen. 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).
App 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/iris as soon as screen turns on. This increases brightness immediately while it's scanning (can be annoying) and will drain some battery. 'Samsung Pay' works only with 'Fingerprint' and 'Iris Scanner'. Try different ' preview screen mask' for 'Iris Scanner'. In 'Fingerprint Scanner', you can add as many as 4 fingerprints (reserve one for Secure Folder). Put your finger on the reader and you can see the detected one highlited.
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: Similar to 'Google Smart Lock' for passwords but with biometrics and less support as of now.
Install Unknown Apps: Allow/Disallow existing apps to install apps from APK.
Secure Folder: The replacement for Samsunh My Knox. Must use feature to serparate your very private and confidential part of the phone. Guide here and video here.
Secure startup: Disabled for me. Should be enabled if you want your SIM, notifications, alarms and anything related to device startup not to start without passing the lock screen after the device boots up. For the kind of short-term memory loss I have, I want to call my phone or want it recieve inputs if in any case it gets misplaced with maybe low battery.
Encrypt SD card: Okay, so your phone is secured by Knox or 'Device encryption'. What about your SD card? Anyone can take it out and access your data, right? Encrypt it here and it won't be accessible to any device beside yours. Be careful to decrypt it in case you want to use it somewhere else or even when you are going to format your device.
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'.
Location:
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).
Locating method: Change the method as per your requirements. I use 'High accuracy' while you can use 'Battery saving' to save a significant amount of battery that GPS uses. I simply turn off 'Location' from the notification bar when not needed or during survival mode.
Improve Accuracy: You can turn this off for WiFi and BT in case you don't want apps to override your decision of not making them search for WiFi or BT when you have explicitly turned them off!
Recent Location Requests; Location Services: Do review the apps that your girlfriend may have installed in your phone; Do review Google Location History and Sharing settings.
App permissions; Permission usage monitor: You can review the 'Permission History' here and enable/disable notifications for permission access on per-app per-permission basis. You suspect an app tracking your location occasionally and want to prove this instead of not granting it the permission? You can do it here.

[GUIDE] Device Settings Menu | Part IV - S Pen, Advanced Features, Maintenance, Apps

Device Settings Menu Guide, Tips & Discussions
Part 4 - Advanced features, Device maintenance, Apps​
If you're new to this series or want to see the index, please read the Introductory Post first.​
Advanced features > S Pen
This section is exclusive to Note series so you should definitely give some time exploring it.
S Pen remote: Displays availability of the S Pen and its charging level. Configure Pen button actions for each compatible App and master control. I've tweaked it a little bit to make 'Scroll up/down' for Chrome and 'Single press' to 'Skip' while 'Double press' to 'Play/Pause' for Music. You can always tap 'Reset S Pen' in Menu in case you want to get back the default settings.
Unlock with S Pen remote: If enabled, you can unlock your phone with your S Pen in case it was taken out while the device was unlocked. In case you've enabled it, please keep an eye on your S Pen.
Screen off memo: Very useful when enabled. Here you can change the colour from the signature colour to classical white. I like the golden colour that comes with the Ocean Blue. However, this golden colour may seem weird to you when you open S Notes with the white background so you can force display Black text in S Note app itself that keeps the golden colour while writing.
Air view; Direct pen input; Pointer; Shortcuts: Very useful features. Review them. 'Learn about S Pen features' on the bottom or watch this 30-min video.
Floating icon: I don't like any over-the-screen icons so have disabled it. You can always open the Shortcuts menu by tapping the S Pen button while it's near the screen. I've also set 'Do nothing' 'when S Pen is removed'.
Alarm: Works when the screen is off since if it's on, you probably be using the remote feature.
Power saver: Although it's enabled for me, internet says it has negligible battery effects. If disabled, the device won't allow you to use another S Pen if your device's one is inside.
Sound; Vibration: Enabled since I don't like accidents. 'Oper Air command' in 'Removal' also helps in this case.
Advanced features
Accessories: Enable 'Fast wireless charging' here.
Smart stay: Too many ideal conditions required for it to work and may take a lot of battery power. Disabled.
Games: Explore 'Game Launcher' after enabling it from here. You can also hide your games from appearing in the menu while they are categorized by Game Launcher.
One-handed mode: A much-needed feature when you're OTG (on-the-go). I had changed the 'Gesture' to 'Button' after accidentally enabling this mode many times. On Pie, if you hide the navigation bar, you cannot check 'Button' mode anymore. OHM is also a shortcut in my Edge panel that is easily accessible from one hand.
Finger sensor gestures: Open/close notification panel or launch Samsung Pay using the fingerprint sensor. Make this a habit. Looks cool.
Device assistance app: Set to Google. Explore settings for the DAA - it was really cool to see Hindi (India) as an option there. Analyzing on-screen text/images is a very useful feature. Read the guide here and here on how to use Google Assistant like a pro.
Multi window: One of the best features and legacy of Samsung and for Note, it's a must-use one. By default, you can use SSV (Split screen view) by selecting it for the required app in recents. 'Use Recents button' is much faster. 'Pop-up view action' can interfere if you generally drag down the notification panel from near the corners (enabled for me).
Smart capture: Very useful screenshot features that you may need just after capturing one. Enabled.
Palm swipe to capture: I never bothered about it but with Note9, I started using it to save presses on my hardware buttons as well not needing to pick up the device in case I want a screenshot.
Direct call; Smart alert; Easy mute; Swipe to call or send messages: Tradional and useful Samsung features. All enabled.
Dual Messenger: You can use two seperate accounts for compatible apps (WhatsApp, Facebook) and restrict your contacts for the second ones. Suggested in case you have multiple accounts. For more James Bond feel, use 'Secure Folder'.
Panic mode: Can be helpful before you try show your Ninja Skills. However, I have accidently triggered it many times and since sending photos is enabled, it's kinda wierd! Still Enabled.
Direct Share: Helps you save an extra tap while sharing something. Ninja guide here.
Video Enhancer: Helps you flaunt the best screen more. In case you are not the natural-colours kind of, Enabled.
Touch sensitivity: In case you use screen protectors or live in Antarctica (gloves), Enabled. Disabled for me.
Device Care
Info: Add a home screen or edge panel shortcut to it as it's gonna be really useful. Tap 'Optimize Now' once in a while. It includes the virus scanning, memory cleaning, storage cleaning and battery optimization. Read below for more on these.
Battery:
Battery Usage: Do review this once in a while in order to identify culprits. 'Refresh' for real-time monitoring. In ideal case, all of your compatible apps should be set to 'Optimise battery usage'. In case any of them not working fine in the background and you need them to, disable the optimization for the app.
Power saving mode: Try all the modes (MID/MAX) once before you get into the Bear Grylls mode. MID will help you while you're travelling while MAX when you want to extend that last single digit juice. Do you want me share my settings?
App power monitor: When you tap 'Save Power', you manually make the apps 'Sleep'. They may wake themselves up again.
Unmonitored apps; Always sleeping apps: Select the apps you want always/never be able to run in the background.
Menu > Advanced Settings:
Notification settings: Get notified for 'unused apps' for days you specify in 'App power monitor' (disabled), 'Battery-draining apps' (enabled) and 'Unstable apps' (enabled).
App power monitor: Monitors apps to prevent excessive usage. You can 'Put unused apps to sleep' and specify the 'sleep delay' to let the feature automatically sleepify your apps (enabled, 1 day).
Fast cable/wireless charging: Enable or disable fast charging. You can disable 'Fast cable charging' in case you more often charge it overnight.
Performance Mode: Customize profiles for phone's performance (Screen resolution, Video Enhancer, UHQ upscaler, Game Launcher). You can then toggle these modes from the notification panel.
Storage: Love to see 512 GB here but only when it's the denominator. You can clean unnecessary data here by tapping 'Clean' or you can use apps like Files Go or SD Maid. User Data is also categorized so you can review and remove files of different types. 'Storage settings' summarizes device storage and you can tap the items to get to respective apps or apps settings. 'Get more space' helps you to delete Large, Unused, Duplicate and Unnecessary files.
Memory: Tap 'Clean Now' to clear your RAM. Likewise, for battery, these apps may appear here again.
Device Security: The virus scanning is powered by McAfee. Since it's disabled by default, enabling it never hurts.
Apps
All of your apps settings including Usage, Battery, Storage (Clear Data/Cache), Uninstalling and Force stopping, Notifications settings, Permissions, Defaults and Version/App details in store. I use 'Sort by size' with 'Show system apps' to occasionally review the apps taking the most storage. Change your 'Default apps', 'App permissions' and 'Special access' in the Menu. You can set 'set default apps automatically' as well. In 'Set as default', I've disabled 'Open links in app' even if they're not installed since I get annoyed when I have not installed an app because I want to browse on Chrome only (reduce usage of separate apps whenever possible). Read about 'Instant Apps' here (you can use these even without installing them). In case you mess up with the defaults and notifications, tap 'Reset app preferences'.

Sir, 5 separate threads for almost everything you could discuss about the device!
I was also skeptical about this and even started in my mind with writing only one thread. But I wanted these kind of threads to be a contribution of the community not only the original post. The original post is only intended to be a reference post that will grow more with participation. And if this would be the case, I think it would add to the clutter if everyone is going to discuss variety of stuff in single thread. Anyways, need recommendation on this and I can consider consolidation as well.

It's a little hidden.
Go settings, device maintenance, Battery. Under the estimated runtime click battery consumption button.
In the following list tap on a random app (not screen or something) and then tap on battery optimization. The select on top "All" apps and allow the one you want.
If someone has a faster approach let me know.
My phone language isnt English so the buttons may have slightly different names.

I believe Bober_is_a_troll meant that you could check whether that option is already enabled for some reason and disable it.

Yes this sounds like you have background services limited to 4. Make sure to check the dev options!
Make sure "background process limit" is set to default.

Can Tasker create an icon to set the volume to a specific value...

...and to set the brightness to a specific value? I can do this easily in Windows, but not in Android.

Perhaps you figured it out by now, but just in case, the answer is definitely yes, I use that very functionality for brightness on my phone:
1. Create a new task
2. Add a "Display Brightness" action to this task (the value in this action doesn't represent percentage, so you might need to experiment with the number to get the desired brightness)
3. Add a "Tasker Shortcut" widget to your home screen. It will lead you to select the name of the task you created.
-It will also require you to select an icon for the widget, which you will do with the 9 squares at the bottom of the task edit screen (I already selected an Android robot icon in the picture).
-When adding the widget, you may also encounter an error message requiring you to open Tasker and exit with the back button to close it out properly in order for the widget to work.
There would be a similar process for volume, but you'd have to choose the appropriate action for which volume you want to adjust: ringer/system/media, etc.

Yes, I did figure it out, but thanks for posting that clear explanation, which is rare. It will probably help someone.
My most interesting program so far is a reliable way to turn the display off and on automatically to save battery power and, more importantly, to extend the lifetime of the power button.
Even with a reliable program, though, Tasker sometimes delays responding when it is closed and the display is off, so I've found that Tasker must be left running all the time. This is easy to arrange: in Android task viewing mode, click the lock icon at the top right of the screen view pane so that it becomes solid.
Such locks persist forever, I think, and are therefore quite confusing to newcomers to Adenoid, I mean Android.

You're welcome. Hopefully it might. I sympathize with the new user, since often it's difficult to get a solid, helpful answer from an advanced user regarding a beginner's topic.
As for Tasker being killed on occasion, unfortunately the circumstances surrounding that vary dramatically between devices. For example, whatever lock icon you're talking about to fix the issue on your device is not on my phone at all, so it would not work as a solution for me.
Do you have the option to "Use reliable alarms" in Tasker? I'm not sure if its presence varies between Android versions. I have that option set to "always"*, and I've never had a single time where Tasker fired late or was killed. It uses a persistent system alarm to keep tasker "in mind" all the time.
*And battery optimization for Tasker turned off, of course

Enabling Use Reliable Alarms doesn't help. I think at this point I would say that getting Tasker to work when the display is locked is not obvious. Perhaps it is documented somewhere.
Basically, the bad symptom is as follows: after the display has been locked for a few minutes, moving the device fails to turn the display on again. Something kicks or locks Tasker out, but only after more than just a few seconds.
Sorry about not realizing that locking an app in memory is not part of Android. I'm using an inexpensive TCL A3 device sold by Tracfone. Locking is nice when you want to avoid startup delays for a task.
