I have a Samsung 50” Neo QLED 4K 2021 (model QN50QN90AAFXZA). For 2.5 years, I’ve used Ambient mode >> My Album >> Screen Photo to display one of my own photos in the tv with no issue. 

But two weeks ago I changed the photo I wanted to display, as I do periodically, and now the photo flashes regularly every 10 seconds—it flickers off and back on in its entirety. When it flashes, the ambient mode “background” is displayed. I notice that the software for this mode was updated on 2024.03.06, so I suspect this bug was introduced with that update.

Some interesting notes: the Samsung default photo does *not* flash. I’ve tested several of my own photos, and all of them flash. Those same photos displayed in “Mono” or “Mono Mat” modes do *not* flash. 

I believe this to be a software issue—how can I report this bug and get a fix?
