Samsung Mobile US' X handle was busy during Apple's event on 9 September, during which it unveiled the iPhone 18 Pro and Pro Max, and its first foldable phone, the Duo.

Samsung's first fold phone was launched in 2019. Given its headstart in this category, the South Korea-based company put out a series of tweets - including one which read 'Let us know when you're done reheating our leftovers'. 

It made another jibe on the name - Duo, by tagging Duolingo in one of its tweets, with the latter already intrigued by the name. 

I'm so sorry, @DuoLingo. They copied us too #Solidarity

Duolingo's social media team was active wondering what would happen to its SEO, with them actively trying to reach out to John Ternus, CEO, Apple.
