Appium with Selenium (or XCUITest for iOS) will shorten your life expectancy and grow you some grey hairs, but there is no other better alternative for testing at user level. It is highly unreliable and each new phone OS version will tend to break your automation

As for finding devices there are a few cloud providers like xamarin or perfecto (never really worked with them in production) that gives you remote access to a lot of real devices and software versions

Having said that try to divert more testing towards lower levels- unit tests, testing on simulators, integration tests with a full phone and browser etc.
