Having ascertained How to capture a screenshot in Plasma Mobile? - #2 by rokejulianlockhart, I’d like to be able to transfer screenshots off my Plasma Mobile device:

  1. I try to access it via

    Screenshot_20240505_041647

  2. but all I see is

    Screenshot_20240505_041605
    Screenshot_20240505_0416051148×284 23.7 KB

Weirdly, it’s acting like 486594 – "Disks & Devices" reports AOSP device in initial charge reporting state has accessible storage, but it doesn't..

I ask because I’d like to upload screenshots to 1895116 - Doesn't adapt to smartphone/portrait (9:16) display..
