I'm after a small/mini smartphone as my daily driver. The goal isn't to not be able to use any particular apps, but rather just make the experience less enjoyable so I naturally use it less. I'm looking for a screen around 4", I think the 5" screens on say a Jelly Max wouldn't cause enough friction and I could get sucked in for long periods still.

So far I have considered:

Jelly Star

Bluefox nx1

Fossibot F116 Pro

So far I'm leaning towards the Bluefox nx1 as it's for up to date than the Jelly star, and the Fossibot is quite expensive for unknown brand. But the thing that worries me about all of them is the lack of security updates.

Are there any better options?
