[Guide][NO ROOT][Android 7.x.x] How-To disable/enable Heads-Up Notifications (adb)

It is a persistent, nerve-racking and heated subject since the Android 7.x.x (nougat) release. Even if you can disable the heads-up notifications in an Android app, they still occur. This annoys many, especially if they is enough for them to display Android notifications in the status bar. This is due to a change in the Android operating system, which is only approached with adb/fastboot knowledge. How to disable these heads-up notifications globally, I show you in today's brief guide.
Requirements
Knowledge of adb / fastboot
Guideline
Enable the Developer Options:
Go to Settings > About
Tab build-number seven time, until you get the on-screen message that you are now a developer.
Enable USB Debugging:
Got to Settings > Developer Options and check USB Debugging
Connect your smartphone via USB to PC
Navigate to the folder where your adb/fastboot are installed to and open a CMD, by right-click > open command prompt here.
Now enter the command
Code:
adb devices
and wait until the CMD shows the serial number of your smartphone followed by the term devices
To disable the heads-up notifications from Android 7.x.x, enter the command
Code:
adb shell settings put global heads_up_notifications_enabled 0
If you want to re-enable the heads-up notifications, replace the command in the last step with
Code:
adb shell settings put global heads_up_notifications_enabled 1
That's it. You can disable nad/or enable heads-up notifications on Android 7.x.x acccording to your personal needs.

And here's a tutorial on how to use this command to block heads up notifications on a per-app basis, like when gaming or watching a video: https://www.xda-developers.com/block-heads-up-notifications-gaming-videos/

Oh didn't see that one. Only one mentioning an App for it that didn't work on my end, which is why I decided to open up this thread. Thanks for the heads up!

Can you change the Display ppi on here?

I remember reading on here that you can change the PPI to 402 on here but I can't remember where I read it. Does anyone know if this is actually possible?

Settings\More Settings\Developer Options. Scroll to Drawing\Minimum Width setting. Remember the default setting before you make changes. I think it's 360DPI. Watch the beginning of this youtube video on how to enable Developer Options if you can't access those settings.

guys, it's not that hard to do developer mode....
To enable "Developer Mode" on Vivo NEX S
Settings>More Settings>About Phone>Tap on "Software Version" 7 times then go to the previous screen. "Developer Options" is now added at the very bottom.
Notes
1. You do not need to turn on "Developer Options" switch to make adjustments to "minimum width" settings in the Drawing section.
2. This does not change the actual PPI of the screen (obviously), only sets DPI scaling, or the ability to adjust the size of on-screen content. Decreasing the value will give you larger icons and make text easier to read while increasing it will make on-screen elements smaller and fit more content on the screen.
ill have to cross post this in the other thread for clarification. apparently some are going through a lot of steps like downloading apps or having to connect to computer when it's as easy as tapping the screen a few times....

Android Q- cannot disable "dark mode"

This is on by default in Android Q Beta 1 and can't be disabled as far as I know. I've checked everywhere and developer options. Anyone notice the same?

I read in a lot of posts that there is no toggle in DP1, you have to run an adb command.
If you're familiar with tasker, you can just create a quick toggle that runs those commands easily.

you can also factory reset. If you factory reset, you can turn on system wide dark mode by turning on battery saver.

Have you tried to turn off the battery saver option?

Go to the play store and download "settings database editor"
Open it and open the drop down menu that says system table and select secure table.
Then find ui_night_mode in the big list tap it and select edit value and set it to 0, 1, or 2. 0 = Auto mode 1 = always bright mode 2 = always dark mode.

Changing animations scale without developer options

Hi everybody,
Is there any way to change animations scale with spesific app, i need this because banking apps don't allow nfc payment with developer options turned on. I searched google but i couldn't find anything relatable to my issue. Any bypassing method is welcome, for example, i don't turn off developer options but somehow nfc payment works.

Late reply but here's how i made it work on Samsung OneUI 5.1 Android 13 , installed com.zacharee1.systemuituner (SystemUI Tuner) by Zachary Wander from Play Store , granted it WRITE_SECURE_SETTINGS permission through adb by enabling developer options and usb debugging.
Steps
1. Install app (the app also guides you)
2. Turn on dev options , turn on usb debug , connect to pc
3. go to abd shell of the device , type "pm grant com.zacharee1.systemuituner android.permission.WRITE_SECURE_SETTINGS"
4. revoke usb debug if you want and turn off developer options
5. go to app and tweak animation speed in the UI menu (0.4 is sweet)
6. set up persistant options (there is a guide in the app)
7. restart and check if the settings persists.
8. put system ui tuner to deep sleep if you only use it for animation scaling

S905X4 Mediabox - Switch/Force apps to run in TV layout

Hey everyone! We've bought a lot of Android mediaboxes with Amlogic S905X4. Unfortunately, all of them came without an "AndroidTV emulation", thus all of the apps are running in a tablet layout and expects a touchsreen, while all that we have is a tv remote (As you can imagine, highly impractical). The mediabox is rooted. Is there a way to force apps to run in TV layout? Thanks for the answers!

It's possible to override the default screen orientation by disabling accelerometer rotation and setting user rotation in the system settings database.
On Android console you enter the commands
Code:
su
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
insert into system (name,value) values('accelerometer_rotation',0);
insert into system (name,value) values('user_rotation',1);
.exit
Info:
user_rotation 0 -> ROTATION_0
user_rotation 1 -> ROTATION_180
user_rotation 2 -> ROTATION_270
user_rotation 3 -> ROTATION_90

Thanks for the answer, I haven't made myself clear - I'm not talking about screen rotation, the problem is that the app layout is set to "tablet", not "tv", so the app "expects" a touchscreen, while all that we have is a tv remote, thus highly impractical. Sorry for the confusion
