Haven’t seen this one yet. My OLED came with the L5 button wobbling around in its compartment.
Going out for a torx screw head tomorrow, I’m assuming this is something I can tighten to the back chassis cover? Every teardown video just removes the back cover off screen so I can’t get a good view of what to expect.
They must have been talking about the screws on the outside of the shell. The back buttons are secured by rivets internally. It’s been like that since the first Steam Deck models.
