Word Attack! (Mobile Java game by South Korean company Linkzen, 2009)
Used to play this game all the time called "Word Attack" on an LG900G phone in 2011-2013.
There are bits and pieces left of the company who made it, they have a twitter account and a blog page from 2009.
I've only found one gameplay video on YouTube from 13 years ago, but it's a port for a different LG mobile phone model, but indeed it's the same game.
Their original website linkzen.co.kr doesn't exist anymore, but there's plenty of it to see on the Internet Archive. There's a timeline on their website from 2003 (their initial launch) to 2018 (last year it's been archived), and in 2006 they started to make mobile phone games I believe. I've recorded gameplay off the old LG900G phone with its original music.
The gameplay from 13 years ago is here: https://youtu.be/U2wgl7Q3u6I?si=iDBoVB5530BQtrPP
