Please give me an example that has viable hardware to allow a seamless and high performance experience.
There was the FXTech Pro 1 and Pro 1 X, which I paid for but never received because China shut it down.
There's also this that I just discovered today: https://digitalprivacy.shop/
and as far as software the de-googled Android and also Android alternatives are both getting incredibly good.
I think the Murena Fairphone 5 would fit the bill. It's no Pixel 8 or iPhone 15, bit it's viable and seamless with the integration of Murena email and cloud.
