[Q] Avoiding Android notification previews - Android Q&A, Help & Troubleshooting

Howdy, folks!
I've been using Android for a long time, and one particular behaviour bugs me. I've spent about a week googling around, sifting through the forums, looking for hacks or an Xposed module, and I can't track down anything.
When a new notification fires, the top bar momentarily shifts to show a preview of that notification. It might be as simple as a title-less notification that some app has turned itself on, or it might be a preview of a new message from some application. Regardless of what the contents of the notification are, the whole top bar momentarily stops displaying all of its icons, the clock, and anything else in order to show some of the text from the notification.
I'd like to stop this behaviour. Let me clarify; I don't care about modifying the contents of the notifications, I don't care about what shows up on my lockscreen, and I don't want to block notifications from showing up at all. I just want them to simply appear in my notification center and for the top bar to simply *poof* have another icon in it for the new notification.
I haven't been able to find any leads on this anywhere. I don't know if it's worth my time developing a little app to try to block this behaviour, or if someone has done it already. If anyone has suggestions, I'd be thrilled to hear them.
I'm using a rooted Galaxy S5 G900V on Verizon, running AllianceRom's KitKat release, though apart from the root access I don't think any of that should matter.
Thanks!

[Q] App idea: Group "persistent" notifications into one notification

I've done some searching and I haven't found anything like this. I'm not an Android dev but I think I understand enough about the model to believe my idea possible in some form.
So...
Programs that run constantly require a persistent notification so the system won't kill them. I run Talkatone, Tasker, Light Manager LED Settings which all have the option to run persistent or take a chance and have them killed without a persistent notification. This sucks because the status bar gets cluttered with things that are always there but I don't need to constantly see them. But Android 4.3, which I'm running, does this by design (for largely good reasons, I believe).
Would it be possible to have a program (I'll call it "Watcher") which creates its own persistent notification that then keep tabs on other programs that you want to always run but don't want their persistent notification.
More clearly, say I always want Tasker to run but I don't want its notification. I turn off persistent notifications in Tasker's options then add Tasker to the Watcher's list. Whenever Tasker gets killed by the system due to resources, Watcher notices this and restarts it shortly thereafter. The advantage is that the system can still reclaim resources when it needs them but the notifications don't clutter the status bar.
I am imagining a rich notification where maybe every Watched app's icon is shown in a small square with a number by it showing how many times Watcher had to restart it recently.
Unfortunately, I'm not an Android dev and I've only done enough research to make me think it might be possible. Does this app exist already? Is it impossible? Is it possible enough for me to consider turning this into my first Android project?
Thoughts?

[Q] Faded dot on the left of the notification bar?

What is that faded dot, which appear sometimes on the left of notification bar... like a notification but it's not?
does it show with headphones plugged in?
If it is as Envious is suggesting, then its the Smart connect thing. Or maybe you are talking about the Noisecanceling which appear like a wave sort of.

Like the one in the attached picture ?
A flag, SYSTEM_UI_FLAG_LOW_PROFILE, can be passed to indicate that certain UI elements be put into a Low Profile and offer less of a distraction to the user. If I had a nexus device (really any device with soft buttons across the bottom) then I would also notice those buttons being replaces by the same dim circle I'm seeing in my navbar.
This has been available since 4.0 and is intended for book readers, games, and other immersive applications.
Maybe you have some sort of app that are running in the background. Try to check your task manager.
It's not related with headphones. It looks just like the one in the attachment but if so it should replace a notification, which i dont see after it disappears.
I'll try to get a screenshot the first time i see it.
And please check the task manager to check what is open. Please take screenshot of that too
Unfortunately, i forgot to check running apps but i dont expect any surprises because it was after a video watch. so yes a full screen app was working but there is no clue that it's for visual enhancement and it just disappears after a page refresh.
if it's a notification, i cant get to read it.
I wonder if it can override the gps icon? Maybe it's a notification that what you are using is accessing your location.
I've checked it with the notifications log, it was empty. So it's probably the hidden icon of the running video app in fullscreen. it emerges when i use mx player, as well. thanks for the brainstorming

How to "hide" the top left icons without silencing the app?

I have an IPcam App called SYSD that keeps 2 annoying icons on the top left of my LG G2 phone, I dont like them at all.
But I need the app to be always on, because it is very important as it should always work, it rings when a motion is detected.
Is there a way to hide these icons without causing an interference in the running app?
Any help? Problem with no solution?
Nothing ?
At all?
You can use something like AOSP Status Bar, but you'll need to root your phone I believe. Any mod that allows you to disable persistent notifications is what you're looking for. There are various options and they're usually specific to your phone model, but that's what you're looking for.

More than 4 Notifications in Status Bar

Is there any way (with or without root) to increase the maximum number of notification charms shown in the status bar in Android P? So far, I've only been able to find a way to customize the clock position but not the notifications themselves. Thanks!
Yeah, I hate this change in Android Pie. With this and the lack of notification LED, it seems like Google is actively trying to destroy Android's notification system.
+1 The entire notification bar is a train wreck. Move the clock back to the right where permanent icons/info belongs, and clear space on the left for notifications, and let them breath. Probably my biggest annoyance with the phone is the whole lack of notification management. Turning off the AOD lead to missed notifications, so I have to sacrifice battery for the AOD... Then the dumbass clock and 4 icon limit is STILL causing missed notifications. If you have weather app and another notification always hanging around, you're down to 1 or 2 true notification icons?! Seriously?? Really hope Google fixes this, but I have a bad feeling this is how we have to live now... constantly pulling down the notification shade to see what was missed.

Google wont be satisfied until our devices are just as hampered as Apple's.
I don't understand the problem. I have an unread email, a few texts, a whatsapp, and an ebay auction won. I can see the text and the email and the dot. I swipe down, see the text and the email are unimportant, dismiss, and there's the whatsapp and the ebay. Sure, they aren't right there, but you don't read the email in the 1/8th of an inch of status bar, you preview in the notification shade or read in the app.
I wish I could only get 4 notifications. Since switching to the Pixel 3 XL I have one persistent notification that my Fitbit sync service is running. No WhatsApp or Gmail notifications, leading me to miss things left and right. I shut off AoD to save battery, but I don't think it worked before either.

you can hide persistent notifications now without disabling them completely. Just swipe to the left and click on the gear icon, and it will give you the option to minimize the notification. this will allow it to stay in the notification tray without displaying on the notification bar.
Got it working. Apparently my do not disturb settings were conflicting.
i have the same issue, with pie it limiting notificatiosn been shown in status bar, in Note 9 al least there is an option and you can chose to show all notifications.
With the last version of GravityBox you'll have an option to remove max notification icon restriction

Changing color, activation of Notifications?

On the S6, when I swipe down from the top of the screen, the giant notification window shows up. This is marginally annoying normally since my home page background is 14% neutral gray, but EXTREMELY annoying at night when I'm reading on the tablet and accidentally cause the notifications to display... My bookreader is a dark-mode setup, and the notifications are blinding white when they display (yes, the screen brightness is about 10-12, but compared to the reader it's blinding)...
I've currently got the tablet in Night mode, which makes the giant notification thing black, so it's not as annoying, but it still keeps getting displayed 'cause of hand position and tablet orientation. And Night mode isn't great for "normal" use so I much prefer something that'll actually help with the notification display.
SO....
Is there a way, even if I have to use a different launcher (I'll need to know which one) to CHANGE the background color of the notification thing (and hopefully the navigation bar background)? I tried Nova Launcher, and it has things that SEEM like they should do something, but they don't change the huge white blob that appears when I swipe down.
Is there a way to CHANGE how notifications get displayed - turn OFF the swipe down from the top of the screen and use something else? If so, how do I set this up? "Do Not Disturb" mode doesn't seem to help.
Is there a way to COMPLETELY turn OFF notifications so swiping does nothing. I can't FIND anything in settings, but I figure I'm missing the "turn off notifications" switch.
I'm also interested in what answers may come. For me it's just about the color; even though I'm dark-themed everywhere using "Swift Installer - Themes & color engine", it doesn't theme the notification panel. Since the theme works everywhere else (even on system apps), this makes me think that 'notifications' is a special case, for some reason.
Curious to hear from others.
Have you tried QuickStar inside of GoodLock app from the Samsung Store? there are lots of mods you can do in there like change the color of the notification pull down.
Thanks. That works pretty well. I can change all the colors on the notification so at least the notification is a black background.
Status bar at the bottom is still bright but that's smaller than the big notification thing. Definitely makes me miss the old Android 6 thing where it just put a couple tiny icons at the top and I had to specifically hit them to see notifications. Never accidentally opened the notifications.
Is there any way to CHANGE the activation for the notifications so they DON'T show up when I don't want them to?
