Hi, im using the same device and same rom, do i need to wipe cache dalvik? Or straight flash and reboot? Thank you!!

Im planning to back up my current rom, or not to back up anymore

Question for those who say it doesn't work: is your device language set to English? Another Pixel 3 XL user and I discovered that the "notch Killer" option will NOT show up in the display cutout list unless your device language is set to English.
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Tyakrish:
Its a Magisk module so just flash it via TWRP or via Magisk Manager and reboot... No need to clear data...

To enable it go to dev options > Display Cutout > Double Display Cutout
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Noxillio:
Magisk Manager will not let me install this. I try to browse to the zip and it is faded and not selectable.

Dear Sir this is good.

What is the SU shell command to turn it off/on? I'd like to have a shortcut/gesture for that using edge exposed.
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] realpanik:
Why I only have the "notch killer" option. I installed this module to HIDE this ugly op6 notch. So just to add a black bar around the notch to hide it, since I'm using linaege os and it has no option like that. What I don't understand is that I had the option for a couple of days, then I kinda cleaned cache etc of the phone and now the "hide option" is no longer in the list. I tried uninstalling and reinstalling the module, but it doesn't change.

Search the thread, you need to change the language temporarily to English United States
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] sanoayyk:
It is working

It is working on UMIDIGI F1 stock ROM!

Now nothc area can be occupied in landscape mode, without being left as a black bar.

By the way, can a cutout overlay set status bar height to a fixed value?

For example, I wanna it to be always 25dp even on a notched phone.

That should look ugly because notch will hide some area outside status bar but I prefer a strange narrow bar to a fat bar just wasting display area.

Did you found a solution? I'm also looking for a shell command to do this
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] _mysiak_:
This universal solution might help to find the system settings name and value, which can be changed from terminal or in Tasker:

1. Open Tasker, add new task

2. Search for "custom settings" task

3. Click on search icon near Name field

4. Select find. Tasker takes a snapshot of all system settings at this point.

5. Change the system settings manually (in your case notch type)

6. Go back to Tasker and click on search icon again.

7. Tasker takes the snapshot again and compares it with the previous one. Any difference will be shown.

Once you know the name, type and value of the setting, you can modify it as desired.

Alternatively you can do it without Tasker. Take a snapshot before and after the change and compare the outputs on a PC:

adb shell settings list system
adb shell settings list global
adb shell settings list secure
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Udzi:
True. But in this case it's a overlay. I just found the solution:

To hide the notch

cmd overlay enable --user 0 com.android.internal.display.cutout.emulation.zigafide

To show the notch

cmd overlay disable --user 0 com.android.internal.display.cutout.emulation.zigafide

Not working on samsung s10 one ui android 10.. No extra option shows up in the simulate display with cutout setting. I know this is made primarily for atock based roms but still O was searching thia from long time.. Request help from the OP.

NVM, there is a magisk module in the repo called "None display cutout" which works on one ui 2. Just use this and then use the adb command to hide the status bar in samsung device (tested on s10 android q one ui 2).
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] jencue18:
How to use that files notchkiller2.zip? Anyone can help me? Sorry cuase i don't know..
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Face_Plant:
1. It is a Magisk module, so you need to install Magisk

2. In Magisk Manager go to "Modules", then tap the yellow button at the bottom

3. Navigate your internal storage to wherever the module is saved

4. Once you find the module, tap it and it will install

5. Reboot

6. Go to settings, developer options, and find "Display cutout" (on my Pixel 3 XL it is under the "Drawing" section with the animation scale options)

7. Tap this and a window will pop up. Select "notch killer" from the list

8. Enable immersive mode and see if it worked
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Face_Plant:
I don't know if this has happened to anyone else, but unfortunately this module stopped working on my Pixel 3 XL after installing the January security patch and updating to Magisk 20.3. The module would install, but "notch killer" was not showing up in the list of display cutout options.

I did some investigating and it turns out the update-binary script was out of date. I updated the update-binary script with the latest one from here and now the module works again. I've attached it to this post in case the original isn't working for others anymore :good:
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] MrPhilo:
Does this command just hide the notch? Like just blacks the sides of the notch and move the status bar down?
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Udzi:
Nope. It just does what this module does, letting all apps use the whole screen. The command is only for people who want to automate it with Tasker (or similar) instead of clicking the menu
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] MrPhilo:
I see, is there a command to enable 'hide' in the notch setting? I'm planning to either get the A3 or A2 as a backup and would like to hide the notch.
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Udzi:
The developer has to answer that, the command just eliminates the click
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] yoshidaharu:
Only showing Notch Killer option, dont find hide notch option :( how to showing hide notch? but anyway thanks :good:
[Xiaomi Mi A2 Lite Themes, Apps, and Mods] Face_Plant:
Are you trying to move the status bar down and fill either side of the notch with black to "hide" it?

That's not what this module does. This module makes the screen contents go all the way to the top of the phone on either side of the notch when "notch killer" is selected in developer options and immersive mode is enabled. This module is only noticable when immersive mode is enabled. Sounds like you might be looking for something like Nacho Notch.

Kind of hard to explain, so I'll get a photo later tonight of what I'm trying to describe and attach it to this post.

Update: Photos were taken in low light with my 6P, so the quality sucks, but it gets the point across. The first photo is notch killer selected in dev settings and immersive mode off. The second photo is notch killer selected in dev settings and immersive mode on. Notice how the app fills the entire screen now, unlike the stock immersive mode behavior.

I haven't updated to the March patch yet. If it also stops working for me after I finally update, I'll see what I can do and post a fix (if I can fix it).

[Xiaomi Mi A2 Lite Themes, Apps, and Mods] GTMoraes:
20.3, though not Canary. Everything else seems to be working. I don't have the option in "notch settings", and I can't even enable the notch killer using the terminal command someone posted before.

I'll try updating to Canary and seeing if that does it

Anyone else have issues with status bar height with this module in android 13?

After screen rotation from landscape to portrait, only half the height of the status bar contents like battery icon can be seen and the other half status bar is covered by the main screen contents below the status bar. Only temporary fix is to change to another cutout and the issue will be back after next landscape to portrait rotation.

[Xiaomi Poco F1 Guides, News, & Discussion] PocoSteve:
Okay so I tried out a bunch of Magisk modules and one of them is "xmlpack - a road to vendor apps" which makes the play store detect your phone as eligible for vendor apps (apps made by manufacturers for their specific phones).

That's great, but then I got this weird notification from Google Photos and this info card under my account :

the attach files thing wasn't working, so here is the link to google photos

screenshots taken on my Pocophone f1

So Apparently, because of xmlpack, Google Photos thinks my Pocophone is a Pixel 3 (Pixel 2's end date is 2020, pixel 3 is 2022, just like my card). If Google Photos just uses the latest xmlpack it finds, as long as the developper of the magisk module updates it, we'll get free OG quality uploads forever ! That sure seems cool, I just hope it doesn't get patched up too quickly...

(Sorry, I posted this in the Help section, mustve been a bit tired yesterday)

EDIT : I since learned that even though Google photos displays this message, it checks more things such as the Mac Address to check if your device is a Pixel.

So this may seem a bit of paranoia I may have but I already got my device unlocked from T-Mobilw but wondering if I flash the Unlocked Firmware (N950U1 from N950U) and then to Android Pie would I lose my carrier unlock that I already got unlocked from T Mobile by doing so. Also would Carrier to Unlock Firmware break the device?
[Samsung Galaxy Note 8 Questions and Answers] MrMike2182:
No you won't lose it because it goes on a spot in your phone that doesn't get touched or erased when you change firmware or whatever. And no your device will not break however if you're wanting to try Android Pie there's one for the N950U1 version out now so you don't have to go all the way back to N950U.. Directions are on the forum already.
[Samsung Galaxy Note 8 Questions and Answers] Mr. Orange 645:
The carrier unlock is done server side at T-Mobile. Once it's unlocked, it's unlocked. Period.
