I think this is a point where we'll fundamentally disagree, for all practical intents and purposes, no regular user ever has or ever will read the manual for their smartphone. Your phone comes with one, have you read it? Documentation is a crutch for complexity and it's only acceptable for hard topics and advanced users. Most people don't even touch the manuals for all the appliances they own, never mind your elderly relatives. If they run into a problem, they'll ask someone to help, not look for the manual.
