Just discovered that photo frame is not only available on your smart TV, it is on my Samsung Galaxy S10+ phone too!
This is a feature is when the phone screen is timeout and turned off, and if your phone is on a charger, the phone will start doing a slideshow of the photos of your albums: on camera or online.
I will show you how to navigate to enable such function:
Go to your phone Settings->Displayscroll down and select Screen saverSelect the albums on device or online albums
Click the wheel on the right hand side of the album to select more details.
When you start charging your phone, the phone will act as a photo frame when the screen is timeout...
You can now sit back and enjoy.
