Samsung Dex screen recording - Samsung Galaxy Note 20 Ultra Themes, Apps, and Mod

I've noticed since updating to One UI 3.0, I'm no longer able to screen record in Samsung Dex, prior to the update I was able to record the screen in Dex.
I've tried 3rd party screen recorders, AZ Screen recorder and Screen Recorder, both only record the audio and phone screen, but the the screen when in Dex.
Any ideas? Am I missing something? Any other screen recorders that still work in Dex?

Video recording while screen off possible?

Is it possible to have the defy recording videos while the screen is off? I would like to document longer hikes and such and the screen is the biggest energy-consumer while doing so.
There are apps which can turn the screen black but i havent found any which let you disable the screen completely.
Whats the matter? Can it be hacked ?
Also is itpossible to record the sound through a headset-microphone while recording videos?
I would prefer using a dedicated mic as wind-noise is pretty strong while riding a bike and i think a headset-mic could work way better.

[Q] Default video player issues

The default video player screen goes blank after couple of seconds and audio is audible and screen returns with touch but it also turns off on touch. Does anybody else had this same issue and how to repair it, if it is possible?

Problems with sound and video recording

Since installing Lineage OS, with Pixel launcher, I haven't been able to record video using the stock camera, or any other camera app I've downloaded. I understand that having Ok Google enabled on any screen can interfere with recording, as it grabs the focus/microphone. But even turning off OK Google doesn't help, as I still get errors when trying to record video/sound.
Does anyone have the same issue, and is there any solution? Ideally, I'd like to still have OK Google on the home screen, but if it is interfering with video/audio recording, have it disabled for just that app. But, as I say, I have tried disabling Ok Google hotword activitation for all apps, and it makes no difference. I don't want to uninstall it altogether.
I have the same configuration as you do but I don't get any problem with camera recording.
I use footej camera from play store and not the stock one.
Have you tried reflashing the ROM?

LG G3 change camera resolution without touchscreen? touch is broke in that spot.

My LG G3 has part of the touchscreen not working. I want to use it to record 4k video, but the camera settings icon is on part of the screen that doesn't respond to touch. Rotating the phone does not rotate the camera icons. All I'm mainly trying to do is switch the video recording to 4k. It's currently on 1080p.
I've tried 5 or so camera apps, and a few of them will put camera settings in the middle of the screen, but as far as I can tell, most 3rd-party camera apps can't record 4k video. Their settings menu comes up in the middle of the screen, and I can choose 1080p and lower but not higher. If those apps are supposed to be able to record 4k, then I guess there's something else wrong with my phone, because they don't give a 4k option. I've never tried 4k on it before at all.
I've read CameraMX can record 4k video, but it uses the same camera buttons as the stock app, so I still can't press the settings icon button.
Is there some other way to switch the recording to 4k mode? Edit a file somewhere or something? Or another camera app that can do 4k and also puts the settings menu somewhere besides the upper-left of the screen?

...Of course! I forgot all about that kind of thing. And now at midnight I dug around in my boxes of random computer parts knowing there's an OTG cable in there somewhere I bought years ago "because you never know when you'll need an OTG cable."
BOOM. Changed to 4k.
4k video recording was going to be the main use for the phone now, and I was getting ready to sell it because it was stuck on 1080p.
I was focused on this specific camera problem and didn't think to try a more generic search of how to access a dead screen. That might have made this thread unnecessary. Oh well.
Now to look up how to increase the recording bitrate. Thank you.

Video record remotely?

I have been using a few GoPros inside my car, mounted with jaw clamps to record some of my driving adventures. I control the these camera remotely via the Smart Remote for GoPro. Mostly it works ok.
Just got my S20 Ultra a few days ago, and god damm the picture/video quality is phenomenal!
Does anybody know, if there is a way I could setup my S20 ultra phone in my car via a clamp of some sort like the GoPro Jaw clamp and have it start recording videos remotely via an app or remote, or voice command etc?
By voice you can use Bixby "hi Bixby record a video with the rear camera" should work...or even just "hi Bixby record a video".
Google assistant may work if you have gcam installed but unsure, using hey Google record a video crashes Google assistant for me, but I also do not have gcam installed.
I would imagine any of those Bluetooth camera shutter buttons (i.e. selfi stick remotes) would work, however you would need to be in camera app to begin with.
