Nice review. I agree with others here that this phone is borderline scam for the price and with all the delays people had in receiving them. Performance seems on par with the $200 original PinePhone which I had a similar experience with.
The one good thing that came out of Purism/Librem 5 is Phosh. It’s a pretty good phone shell/UI for other more capable Linux phones to use. I particularly like Phosh for its on-screen keyboard Squeekboard which allows for custom keymaps.
