Whenever I need to help someone on their phone/PC or answer a question it's a UI problem in 80% of cases. On phones button icons are an inconsistent mess with no visible way to find out what they mean. The menu bar on Android is at the top, the hardest to reach place on the whole display. Fast list scrolling and other details on phones/tablets are ignoring left-handed people. Phones have 6 inch screens but maximum font sizes are still too small for some users. Interacting with Android's notification list while it's being updated is simply impossible if an app shows and hides progress updates multiple times per second when fetching new content, making the whole list jump up and down. All those problems affect not just one generation and were solved at least a decade ago. And it feels like all I can do is press a few buttons for them or say "turn it off and on again", and yell at clouds inbetween.
