I’ve had my SD over a year and the screen has never responded to touch. Ever. I only found out yesterday that the touchscreen wasn’t the two touch pads… I’ve looked into troubleshooting tips to get it running. But it would’ve made setting up remote play apps so much easier to be able to touch the keyboard.
Probably would’ve made some games playable that I just assumed weren’t deck compatible.

I wonder how many people with steam decks that don’t have functioning touchscreens.

Like someone said, you’ve had to have accidentally touched the screen at some point and it should’ve done something. Well I’ve intentionally tried using the touchscreen and it’s never responded once. I don’t have a screen protector installed, it’s fully updated, even tried beta updates. I think I need to do the battery storage mode thing to test it or boot into BIOS and make sure it’s enabled. It’s fine if you don’t use it, but to not know that you SHOULD have the ability to and don’t is completely different. Talk about frustrating…
