Hi guys.
I've been using DeX on a S20 as my daily work setup (3 days a week, at least), and happy with it.
Would be more if my monitor connection wasn't randomly disconnecting, sometimes for a couple of seconds, other times until I disconnect either the hub cable (I'm connecting HDMI via a small hub with HDMI + 2 USBs) to the phone or the hub power cable.
Now, I know this usually is due to power issues, but in this case I don't find it's the case. I'm using my work laptop PSU (yeah... the one which is collecting dust under the S20 because DeX is just simpler and better for a split-work environment ;-) ), which is no shy of power, and works perfectly with the laptop itself, and I have tried using another simpler and weaker PSU (but adequate to powering the S20 with this stuff). Both keyboard and mouse are connected by bluetooth, so they don't draw power.
I've been experiencing this behaviour more and more, increasing a bit over time, but with no discernable pattern. I thought it might be related with the couple latest firmwares, but I doubt it.
So before pointing the finger to the hub (which is my guess) I wanted to ask you guys if anyone is also feeling this increase or if this is happening to you too.
If this proves to be the hub I'll have to order another one... grumph... but this time I'll order one with an ethernet port and maybe an extra USB-C one. Been missing that.
Thanks in advance
