I am a life long Linux user and programmer well accustomed to searching for support and fixing issues with software. Recently I got an RSI from programming and could not use a keyboard for 10 months. I could only use my Android phone. There were so many problems and I had so little insight. I _did_ search for answers and found contradictory or incorrect instructions. Often I had to resort to uninstalling apps and taking my chances on their competitors. This strategy had a very low rate of success. Many things I just gave up on. I essentially lost 10 months of productivity and became despondent. One specific problem I had was that I was unable to control which PDF viewer would open automatically when I downloaded a PDF. For not particularly interesting reasons regarding my workflow, it was important to me that Adobe open instead of the viewer built in to the file navigation app. I followed the instructions online to rectify this. However when I navigated the menu to the appropriate place, the option simply didn't exist. I don't fully understand, I'm not and will never be an Android dev, but I believe it had something to do with the built in viewer not being a first class app but some sort of "applet". Deep in this frustration it clicked with me; this is how most people see computers. Black boxes that work against you. Unfathomable and unserviceable. PSA: Stretch your hands. Take care with the ergonomics of your keyboard, mouse, and desk. If typing hurts - stop.
