Not really a feature of the phone, but a design theory. I want my small phone back. Not this “zenfone 9” size small. Like HTC One size small.
Make it bifold wallet sized, and ~1/2"thick.
These hugely tall phones where you can’t reach the top third if the screen without dropping the thing are just annoyingly huge. Then they make them so thin they can’t fit a big enough battery for a full day use.
Beyond that would like an under display fingerprint sensor. Rear and side mounted always have issues with cases for me, and make it more annoying when using the device while it’s on a desk.
I haven’t found anything solid. It’s dropped off my plate for now.
I will probably end up self hosting some xmpp for it.
