I'm currently using the Atom. I love it, but it really takes the "small screen" idea to the extreme.
Texting is possible with swipe typing, but for more than a sentence, I use voice recognition, and I don't even try to write e-mails on it unless it's urgent.
Typing passwords is an exercise in frustration, so I use Bitwarden with a PIN.
Sometimes I have to turn the phone sideways to even show a button that needs clicking.
I've uninstalled the browser, cause it was pointless.
And you better have good eyesight.

That being said, for my use case it's perfect. What I wanted was a "dumbphone+" that can also use messenging apps and e-mail, act as 2FA, sync with my Nextcloud and has a camera for scanning QR codes.
