option to change aspect ratio get's disabled when i enter expert mode and got to settings

Hello everyone.
I have a Samsung Galaxy S9 and when I try to screen mirroring the phone to a 16:9 tv, using a HDMI cable or through wifi using Chromecast, I have black bars on the top and on the bottom of the 16:9 screen since the screen aspect ratio of the phone is 18:5,9.
If I use the Smart View feature of phone to do screen mirroring, the app has a floating button where I can change settings of phone to customize the mirroring, including change aspect ratio of the phone screen to 16:9 to best fit on the TV screen without black bars.
See images attached. Only in Portuguese Brasil (sorry).
My phone is not rooted so I think it is possible to develop an App that changes aspect ratio of phone without root (at least on Samsung devices).
To help developing, I extracted Samsung Smart View apk of my phone to help on knowledge of the function used to change aspect ratio included in App.

Help is needed.
Thanks.
Good afternoon people.
I bought an S9 2 weeks ago and yesterday I noticed that when I put the maximum resolution of the camera (12mp) to take pictures it automatically changes to 7.9mp every time I reboot. And when I select the camera to be in full screen, it goes back to the initial configuration without me touching anything.
Is this normal?
Thanks.
Just found out. When i choose the maximum resolution it changes to 7.9 because i tuen the full screen mode on camera. And when i put back the 12mp resolution, the full screen mode turns off.
I'm gonna leave this here in case it's useful to someone else.

Full screen mode = 18.5:9 aspect ratio, if you check the highest 18.5:9 aspect ratio available in camera settings you'll see there is only one and it is 7.9 MP
12MP = 4:3

Getting used to it yet.
We do indeed have HDR support, but it may be disabled by default and can only run on select apps.
1. Install a custom launcher like Nova or activities shortcut creator
2. Create an activities widget or gesture shortcut
3. Go to Settings
4. Find and select ’Video Enhancer’
5. Launch it and it will reveal the hidden setting
Alternatively, use the Magisk module HiddenSettings and modify the setting: hdr_effect 1
How to test if HDR is real:
Download an hdr video from 4kmedia.org. Change to full brightness and set screen mode to Adaptive. Hide navigation bar (use the quick shortcut). Play the video in the native video player. You'll then slowly swipe up on the Recents button, but without taking your finger off.
You should notice UI and graphics appear vivid. This indicates presence of gamma being applied. When you release your finger HDR is switched off. Saturation is a hue value, while gamma is brightness (how light or dark a pixel is). The real test would be to know if they are doing real-time processing, which is how actual HDR on TV works.
Hy is it possible doing this without using magisk ? or should we root the phone

Hello! I have the Ugoos UT8 Pro, android box. HDR only activates when watching an HDR video, but when the video is off, the screen goes back to SDR. This method you speak of, can it be done on my device to force enable HDR?

Is there a way to do it on sony xz2?
Hello everyone,
I'm writing an application which requires the height of screen to render. The problem is that I couldn't find any android's package to know if the full screen gesture mode was turned on or off to calculate the real height of the screen. Is there any way to check that mode, or even better, to get the real height that I can display my content?
Thank you very much!
A little help: what is the default value for small width in developer mode ?

It depends on your device. One way to go back to default is to search settings for "zoom" and make display zoom normal or default, that will automatically reset the value in developer mode.
Or, try a value like 384, just a guess
