Old one was totally outdated & not really secure [Android 5], touchscreen didn't work that well anymore. By chance, I entered my phone operator shop & there was a bargain. So I took that opportunity to change it. Now my dumbphone is uptodate & secure [Android 13].
I didn't & don't need new features, though now I'm using it to make contactless payments.
Oh & I also surrendered to some coworkers/friends & installed Whatsapp, that crappy Meta thing. I loathe myself.
