What phone is that?

is that a Daylight phone!?

Is that the HiSense A9? I was hoping they would release a model with a color eink display and have been eying one since the A5 was introduced but the relatively high price, (because of the eink display) wonky Google playstore support, and low battery capacity kept holding me back. I'd really like to see an eink phone with a week, or longer, stand-by time and think this would be doable with a big battery. The HighSense A9 also doesn't come with an IP rating so be careful with splashes around the pool, the main reason why I'd want one in the first place because of bright sunlight.

Looks like a Boox palma (not phone, but phone sized tablet)

Boox Palma. Not a phone as it has no SIM card which I prefer. Can't flash graphene on it but I don't use it for anything sensitive. I just use when outside for a couple of specific tasks and of course plenty of trading content

Also like Derek states, you don't really want to be using these devices as a daily driver due to then running older android versions which can be an attack vector. A secure WiFi connection then run obtanium on for some foss apps without login credentials, a decent browser and Nostr client with npub watch only login in my opinion is ok. But depends obviously on threat model.

Boox Palma, battery life is great as long as you don't load too many apps on it, don't leave WiFi or Bluetooth running.
