Yes. Please dogfood. I got a free handset on Boost Mobile for $15/month I can use to dog food my web designs. It suffers the same problem as your iPad - 90% of the modern web is death to this poor old Samsung. 300MB home pages are now common. I bought a decent tablet with a crack in the screen for $20 on eBay. It's perfect for testing. There is literally no excuse not to test your designs. There are so many more tools available in 2022, and the web standards have become so much kinder towards writing lighter pages (e.g. things that were Javascript now moving into HTML and CSS).
