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.

You have commented the same query on each of my parts. I have already answered you here where the similar discussion is already going on. Let's discuss there and keep this thread clean. Also, the 'why am I posting this' is already described in the Introductory Post.

thanks, op for the posts, very useful

Greyscale display mode on Note 9 Pie variant

When I had a OnePlus I would use it's greyscale display feature quite often, very useful for power saving etc.
I am aware that within Google devices running Pie that a greyscale option is available along with Do Not Disturb.
This feature does not appear to be ported over the the Samsung Note 9, which is a shame.
Does anyone know of a third party app or Tasker feature that could enable greyscale mode on the Note 9 where required?
Thx

You can enable Monocromacy in the Simulate colour space option in Dev options and probably get a similar effect.

Go to settings -> accessibility -> visibility enhancements -> colour adjustment , turn it on and select greyscale.

Many thanks for the tip. This achieves the desired result but is a bit fiddly, do you know if this is accessible via Tasker, or does a shortcut exist?

I made my own Tasker task shortcut on the main screen for this purpose.
The task only uses one action:
Add action -> Settings -> Custom setting
Type: Secure
Name: accessibility_display_daltonizer_enabled
Value: =:=toggle=:=
If it doesn't work for you, you can try finding the correct custom action with built-in Find function.

I see you got an answer regarding tasker. I can't help with tasker cause I've been too lazy to dig into it yet

Under the accesibility settings go to advanced settings, from there you can set the power + vol up shortcut to control the monocromacy. I've gotten quite used to this function on a OnePlus 6 and have been using it this way on the Note 9.
I think the OP6's reading mode gave it a yellowish, e-reader like tint though, which made it better imo.

Game mode profile

So I think just about every game on my oneplus 7 pro triggers a built in thing called gaming mode. Is it possible to create a profile that begins when that gaming mode starts and ends when that gaming mode ends. In this way I adjust things like volume levels and screen on time along with what the gaming mode does. And once for all of them instead of a profile for every game.

My guess is there is a custom setting that defines the status of the gaming mode. That's only a guess since I don't have a One plus.
You could use the native tasker settings -> custom setting action to see if you can identify what changes when the game mode turns on. Tapping the magnifying icon [emoji361] will bring up an assistant. Once you identify the setting, it can be used in a profile context (system -> custom setting).
From some online reading, I also think that the games that trigger game mode are entered in a list by a user. You could use an app context with each of those games selected so your profile activates whenever the game is in the foreground.
Hitting the gear/cog icon when the profile is selected will bring up settings for the profile. One of those settings is a toggle for restoring settings when the profile exits. In the case of an app trigger, when a different app is in the foreground, the settings made in your entry task will revert.

Upon starting a game that starts game mode the only thing that this method finds is a screen brightness change. when used from state. And nothing when used from event. Strange because if a game is triggering a system setting or something there should be something for tasker to see get triggered so a profile could tie into running while it is active. Much like a profile that would trigger upon phone charging for example and end when not plugged in to charge any more. Any other idea how i can identify what is triggered (for game mode on/off) to set a profile to run along with it?

Yes in game mode you add whatever games you want to trigger the mode. On my LG G4 I had a profile for each game but the profiles were problematic. Some of them would turn on and off while the game was still running. If I can have a profile that runs when game mode is active and ends when game mode is not then I would completely avoid having a new profile for every game.

I was suggesting using the custom setting action in a task to determine the setting. Then use that information in a profile to monitor it.
You can attempt to manually identify the custom setting (if that's what is controlling game mode). See here.
I'm thinking the mode reverts as soon as you leave the game to return to Tasker, so the built in assistant may not catch the change. Grabbing the settings via ADB and running a diff on the before and after may be the only way to go.
Otherwise, someone in the device forums might have insight how this mode is monitored.
As far as the app trigger approach, sometimes you can stabilize the task by putting a wait action at the start of an exit task and then stop the exit task of the calling profile is active (%PACTIVE).

Thanks for the reply with a method to identify the setting. Assuming that it is a setting. Using the custom setting action is a task when tapping on the icon it says to toggle the setting and return to tasker to find out what it is the results ended the same as attempting to use it by the other ways. It returned nothing or brightness found. I'll have to give the method in the link a try and see what happens. Will report back, might be a couple days.

I finally was able to identify the setting for making the profile, thanks much for the help.

Tasker keep screen on Android 12 issue

Hi,
I have set up the display timeout option with the settings below but it doesn't seem to work. I am using an oppo phone on Android 12.
Create a new task. Select the “+” button. Select “Display” followed by “Display timeout” Select the time span you want to set and then save. Now select “Profile” and click “+” and then “Applications” Mark the applications for which you want to activate this Tasker profile.
Then I open the app but after 15 seconds the screen turns off which is the default device screen timeout.
Is there no way to override this? Maybe get tasker to somehow keep interacting with the screen to keep it on?
I've tried this on a few apps and have got two different messages..
One says screen will stay on for 15 seconds which is the system screen time out.
Other says tasker will keep screen on but still times out after 15 seconds.
Really want this to work as some apps like games I don't want timing out after 15 seconds and I don't want to increase the system time to couple of mins for every app.

Hi,
I have the same problem on my OPPO A74 with Android 11 ((ColorOS Version V11.1). It seems impossible to create a task to change the screen time out; not in connection with a profile, shortcut or widget. The amazing thing, though - when you test the task in Tasker it works perfectly fine.
Media Volume, I think, also doesn't work. Other app connected profiles like autorotate or display brightness work well. I wanted to test more but I can't find the time.
I really miss the screen timeout though. It drains the battery too much to set it constantly to 15 minutes or so, but for some apps less simply is annoying.
The developer created some apk to help with some OPPO related problems, unfortunately, it didn't help with this one (sorry, I can't remember exactly what it was).
A kind of workaround: Once you've activated the Developer Options an your phone you can enable "Keep screen on while charging". When you need longer screen time, just plug into a charger.
But using a Tasker Profile would be much nicer.
Hope somebody knows a better trick.

Not sure if following could help your situation ( only for your gaming situation )
Create a new Profile, choose > apps > add your game apps in it. click left top arrow when finisning add gaming apps.
Tasker will pops-up task list > creat new task > Screen > Turn on.
** when above profile is complete , click the task when you are still in Profile list. Hold the task, it should pops-up with option exit task. Choose this as exit task.
Play around to see if this profile is working when gaming apps in foreground, screen never turn off.
EDIT: Try first not move the task as exit task. ( make the task as normal entry task )

Thanks for your reply.
Creating the profile is not the problem. It just seems that Tasker cannot change the system's setting. As mentioned, there is no problem when you create a profile allowing the screen to rotate using a speciffic app (and others as well ) I have no idea, why it does not work for the screen timeout.

I use no screen timeout, I use "screen turn on" in your situation as my op., enough I've not tried it on my Samsung A71.

"Display / turn on" works fine when I want the screen to turn on with a notification. But the screen turns dark after the system timeout has passed. I've also tried "Display / Stay On / with Wireless, AC or USB Power" and with the AutoInput Plugin "Screen Off Or On: Turn On / Timeout Never" but the screen always turns dark.
Those Profiles always worked on my other Smartphones (LG -D405, LG-K10 and Moto G6). I believe, it's the ColorOs that's causing the trouble.

below is a task ONLY FOR ROOTED DEVICE., no harm to try even if your's not root.
New task , run shell command , in the command input
there is a button 'use root' , check that button also.
settings put system screen_off_timeout 200000
** 200000 I'm not sure sure equals to how many second., just give it a try and if you get a longer screen on time from your issue it means it is working.
also, make another separate task, search for 'custom setting'. look up from there I thingk it is in system something about screen timeout.
EDIT: run shell command task suggest you run it manually., than see if it works. if not, restart device to check if it requires a restart in order to accept new timeout settings.

I feel like I'm in Star Trek - "To boldly go, where no one has gone before" XD
When I try your suggestion, I only receive the message that my device isn't rooted.
Btw, for some tasks it is necessary to enable the Write Secure Setting Permission (f.e. Set Assistant), where xou have to setup ADB on your PC. Would such a procedure be registered by the phone as rooting? Anyway, I don't think I would dare to do something I know so little of.

Another solution I was thinking of, is it possible to create a tasker quick tile/ quick setting to change the system screen timeout.
So instead of having it change for certain apps which isn't working at the moment.
Maybe if we can change it from the system so will be for all apps. You can create two separate quick tiles to toggle between different screen timeout settings.

The newest version of Tasker (6.0.9) comes with Tasky.
Tasky offers the possibility to activate premade profiles. One of them is "Keep Display Awake For Apps". And that one works with my OPPO Phone.
I also tried "Auto-Mute Apps", another profile I couldn't get working. It also works fine.
To switch between Tasker and Tasky you just have to click on the "Three-Dots-Button" in the right top corner. It's not like switching apps but using different user interfaces.
Good luck!
- Sorry to say, but this seems to work for some apps and not for others. But at least sometimes it does work.

Thanks for replying back to this thread to inform me. I tried it and it works for the app I was trying to make it work for which is good! Makes it so much easier now.

Themes / Apps / Mods [App] Fix of buggy proximity sensor - Locking screen from being pressed during phone call

Note: app compatible with any phone with 1080x2400 screen or lower. Probably higher too, try it. Also it's impossible to make such block when talking in messengers (more precisely, it's difficult). App won't work without gapps, rare case.
Instead of classic reliable optical sensor we have sucky ultrasonic one.
Sometimes it does not turn off the screen while phone call and something is pressed with ear or cheek up to dropping call.
Popular workaround is app "Call Proximity Sensor Fix" which automatically turns off the screen. Or you can press the power button immediately after the answer.
But IMHO this is inconvenient because if you need to look at something on the screen it will not turn on by itself which is so familiar.
My simple application makes screen insensitive to taps. And unlike analogs soft buttons and status bar are blocked too (but not gestures).
On screen will be translucent button that disables lock if you need to use the phone:
– Long tap on button - unlock (button will turn green)
– Short tap when unlocked - lock again
– Long tap when unlocked - remove button at all so as not to interfere with e.g. for entering text
When second call comes in screen will automatically unlock so you can easily answer or hang up. Then it blocks again.
When manually launching the application there will be a question whether to enable 4 seconds delay for an outgoing call. So you able to choose SIM card.
Made by powerful Tasker, the project was exported as standalone application via App Factory. Implemented via scenes with new full-screen blocking type.
Location of button adapted for default AOSP / Google Dialer. It can be misplaced for third-party dialers and / or interface scale. It's impossible to cover all possible variants. So if it really bothers you, install Tasker and project below. Then change coordinates of the buttons.
Installation
Follow manual carefully, otherwise nothing will work.
Application is safe and doesn't have internet access.
1. Download APK below this post
2. Install it via file manager and launch
3. Answer the question about delay, decision can be changed later by launching app again
4. Open Settings > Apps & Notifications > In-Call Screen Lock
5. In "Notifications" turn off them all completely, otherwise they will be annoy you
6. In "Permissions" enable everything: Contacts, Call List and Phone
7. MIUI: right there in application settings enable "Autostart"
8. MIUI: and in "Background" select "No restrictions"
9. Custom: Settings > Apps & Notifications > Advanced > Special app access > Battery optimization > All apps > In-Call Screen Lock > Don't optimize
10. Custom: Settings > Apps & Notifications > Advanced > Special app access > Display over other apps > In-Call Screen Lock > Allow display over other apps
11. MIUI: Settings > Privacy > Management > Special app access > Display over other apps > In-Call Screen Lock > Allow display over other apps
12. Settings > [MIUI: Advanced settings] > Accessibility > In-Call Screen Lock > enable "Use In-Call Screen Lock"
If you using Tasker
1. Download ZIP archive below this post
2. Extract file from it to phone/Tasker/projects
3. Tap on "House" icon at the bottom > Import Project > In-Call_Screen_Lock
4. If you don't need a delay on an outgoing call: delete / disable action #3 ("Wait") from the "In-Call Lock Start" task
5. Custom: Settings > Apps & Notifications > Advanced > Special app access > Display over other apps > Tasker > Allow display over other apps
6. MIUI: Settings > Privacy > Management > Special app access > Display over other apps > Tasker > Allow display over other apps
7. Settings > [MIUI: Advanced settings] > Accessibility > Tasker > enable "Use Tasker"
UPD: files updated, fixed small bug.

No.

Tested now on my RN10-pro... works just fine! Thank you!

Tested without gapps and it didn't work. I use the standard phone app from Arrow OS. I do all settings from your instruction.
There was no 4 seconds query of the sim card. The and no lock screen button.

Unfortunately, APK's exported by Tasker always have dependencies from GMS no matter actions it should perform. Sorry, I can't fix that.

I reinstal Arrow with Gapps and Install tasker. IT works great! Thx a lot! Now ist this Phone uesable.

Great application. Tested it via Tasker and works. Thank you so much!
Small question, if you do use the power button while in call to lock the screen and you unlock it again and then use your unlock button, it unlocks but the button disappears so you can't lock it again. How do I get the button back then?

Note: sensors are automatically calibrated and sometimes this creates a problem.
To cleanup and recalibrate the sensors, all you need to do is this:
Bash:
# dd if=/dev/block/by-name/persistbak of=/dev/block/by-name/persist conv=notrunc
For me that solved everything on official MIUI V13.0.12.0 (and previously on V12.5.9.0).

That's strange. I tested as you wrote and button visible, nothing in profile logic should block its appearing. I used clean Android 11 and AOSP dialer.
As possible workaround please test this: Tasker > tab "Scenes" > Lock On > tap on lock icon > tab "Long tap" > action "Show Scene" > tick "Block Overlay+"

That's legit for classic sensor, but I'm doubt, that ultrasonic store its calibration data there (if even have it). "Sensor" unreliable just by design.

Thanks for the information. Tested it and ticking the block overlay + fixes the issue. I guess it's because even though I'm able to tap the icon and other call icons the phone is still locked. I guess the overlay + makes sure that the lock off scene is still visible on the "lock" screen. I'm on Samsung One UI 4.1 with the native Google dialer.
Thanks for the help.

ultrasonic sensor can be even manually calibrated and the calibration is indeed stored and used.
Also: the ultrasonic sensor works in software, relying also on the position and angle of the phone.
If that measurement fails or is inaccurate, everything is ruined.
Trust me: try to do a fastboot flash of V13.0.12.0 then reset that partition as I said.
Then you can tell me if it improves or not.
For me now it works perfect both in DUO both in the stock dialer and messenger.
