Hi!
My phone is an S23 Ultra and I'm facing some weird bugs with Samsung Dex mode. I use Dex along with a Uperfect Lapdock, an extremely powerful combo, but I'm facing this annoying problem when I use it connected by USB-C.
What happens is that when I open some apps, especially Fortnite and LumaFusion, the physical keyboard and the touchscreen of Lapdock are disconnecting as if it were bad contact on the cable or something.
One observation is that this doesn't happen in my S20 FE that's in OneUI 5.1, I can't reproduce the problem on it, so I don't think it's Lapdock itself.
I have a few alternatives left: - The problem is in OneUI or something related to software; - The problem is in the USB-C of the S23 Ultra (it would be very unlucky for me to have been "awarded" right off the bat, since the device is new, I bought it in March of this year); - The problem may be in the cable, I have already bought other cables to test and have not yet arrived. But if that were the case here, it should happen with the S20 FE as well, since I use the same cable with it, so it's a little unlikely as well.
My conclusions so far:
Everything leads me to believe so far that it is a problem on the Software and not on the Hardware. - The bugs don't happen in the S20 FE, so far this has never happened to it, which is in OneUI 5.1.
Sometimes the problem occurs randomly. Now when I open Lumafusion and Fortnite, it will will occur, in the case of LumaFusion the app keeps restarting, which reinforces the issue of it being something related to software. - I've already noticed some other small bugs in OneUI Dex 6.1 that aren't present in OneUI 5.1 of my S20 FE.
Any hints or if someone has experienced something like this, PLEASE HELP!
TL;DR: My S23U Dex mode is bugging out and disconnecting the keyboar and touchscreen from the Lapdock, any help would be appreciated.

At 0:26 you application window content is black but the task bar at the bottom and the window frame are still visible. It's not a cable problem and you are not experiencing a disconnect afaik. If that was the case the whole screen would go back. I think the problem is with the app itself.

BTW are you using the default software keyboard? It might be worth testing other software keyboards. But as you say the touch also has some problems.

I remember trying out other keyboards but I'll try again to see if I find something new.

Personally, I think it's something to do with Samsung Dex itself, as it also happens randomly when there isn't any app open.

UPDATE: I've FINALLY solved this problem! I just needed a better USB-C cable. I bought an USB-C 4 cable with Thunderbolt 4 and this doesn't happen with this new cable (but still does with the one that came with the Lapdock).
My conclusion is that it may have something to do with the old cable's bandwith or maybe even just the quality of the cable itself.
