> Not everything is an ism. Doro makes phones for people with poor eyesight. Most of those people are old. Glancing at their product catalogue, it doesn't seem much different from what you're doing with Lineage OS. Not everyone will have a geeky son to make a customised Lineage phone. Doro fills a niche. Be thankful someone does.

My father has a Doro handset. I recommended it to him based on a misunderstanding of the advertisement* and have regretted it every since.

The user interface is confusingly designed, with nested menus ten levels deep in which pressing the wrong button can just delete your message, contact etc. without waiting for confirmation. The screen is tiny and low resolution - I have 20/20 eyesight and still can't see what the status icons are supposed to be! It is so awkward to change the ring volume and unclear what mode the phone's in, that my father doesn't trust it not to ring at concerts, so leaves it at home.

All that leads me to the opinion that Doro is just predating on older users and their carers with the idea of being simple and accessible, whilst actually doing absolutely no real UX research. Yet, their 'dumbphones' approach the price of some basic smartphones which have hardware orders of magnitude more powerful.

* This was back when 2G was new, and I incorrectly assumed that it would imply some level of internet capability on any handset new enough to support it. The device in question does not have any internet support.
