Screen Recording in A50/70 or any OneUI based Samsung device.

[MrSKhan12]

So, Samsung isn't providing screen recording feature in their OneUI based phones But here's a way to record screen using an app

App's name is MNML

Available on play store

Just download and give required permission.

It'll also add a shortcut in notification drawer for easy access.

Attaching screenshot of app and my notification drawer. 

I used it in A50 and it's working good enough.

Hope it works for you as it did for me until Samsung provide an official update with screen recording for OneUI based phones

There is not "1" way... There are many ways to record screen, even Samsung itself made an app called "Nice Shot" for screen recording

"Nice Shot" not found in Samsung Store. I installed MNML and OneShot. Tested both and I prefer MNML. OneShot puts an advert randomly in your video and it records through the mike unlike MNML which records the game's audio.
Just found Nice Shot. ver 1.1.04 in apkmirror.com. Going to test it in a live online presentation soon. Uninstalled MNML for the time being

Update 04/22/20 - 1 
Just recorded an online meeting with MNML, found MNML doesn't record the audio unless I use the phone's mike, which would have recorded my dogs barking and any external sounds. MNML video quality however is better than my laptop's considering the meeting was a webinar. 
Have downloaded Nice Shot 1.0.6 and removed 1.1.04 because was advised by an online forum that 1.1.04 isn't working as well as 1.0.6 (have personally confirmed that too. 1.1.04 did't start at all). will try 1.0.6 in my next meeting.

Update 04/22/20 - 2
Tried MNML again with a handsfree kit plugged in, kept the mic button pressed, no sound recorded. Nice Shot doesn't record Zoom meetings, it considers Zoo as a call and refuses to start.

go for NICE SHOT

If your device supports GoodLock app, then use Nice shot (Nice Shot works as an extension of Samsung’s Smart capture feature), one of the best option..but if GoodLock app or smart capture is not available, then MNML is the right choice, quality of video is really appreciable..👍

is there not a system in samsung a50 to record the screen is it necessary to download the app ?

[MrSKhan12]

nope, there's no inbuilt screen recorder in A50 with Android 9 but they introduced it in android 10 update, I'm using the inbuilt one now when i was on android 9 i used the app mentioned above
