what is the best phone to get the best sailfish os [duplicate]

That's a very subjective question, opinions will vary greatly.

I'm still using Jolla1, but you can't buy them, so you are left with a choice of a few Sony devices that Jolla officially supports;

Xperia 10, Xperia XA2 and Xperia X then there is the Gemini PDA.

Then there are community driven OS versions for devices other than what is listed above and is not supported by Jolla.

Take a good look through this forum and read the myriad of problems with ALL of the above listed devices. If you are put off from watching a video about the OS, then perhaps to stick with iPotato/Android offerings instead. I will continue using my 5 year old Jolla1 until it dies or is no longer supported, I am totally loathe to buy ANYTHING made by Sony, but that's just me.

I would like to balance @Edz opinion on Sony - I had only the best experience with their hardware and would fully recommend it :-)

may i ask you please which sony is best please

@v8sk I would recommend getting at least XA2 or even 10 for future proofing, as while X will be getting general Sailfish OS updates for the foreseeable future, it won't be getting any more Android emulation layer and driver updates, kinda like other older devices (Jolla 1, Jolla C, Jolla Tablet).

Choosing between an XA2 and 10, you want to see them next to eachother. The screen ratio is quite different.

Down here the XA2 is quite sold out, but secondhand they are still for sale with good prices.
