Sailfish opens its HW adaptation code for Sony Xperia

This brings up one of the more frustrating things manufacturers do, what exactly is a Sony Experia X? The website for my region (https://www.sonymobile.com/au/products/phones/?cpint=mn_sony...) lists:

* Xperia X

* Xperia XA

* Xperia X Performance

* Xperia XZ

* Xperia XA1 Ultra

* Xperia XA1

* Xperia XZ Premium

I have no idea what the compatibility is like between these phones. Are they all variation on a base phone or radically different? Is the X the latest or is the Z? Are we going backwards through the alphabet? There's a lot I dislike about apple, but the one thing they get right is limiting their SKU's.

AFAIK only model F5121 is officially supported. There has been speculation, which other models should be close enough, but I'm not aware of any confirmed information. https://together.jolla.com/question/164016/sony-xperia-x-f5

Wow, this is great news. I'd pretty much given up on sailfish ever being meaningfully open - let's hope it's not too little, too late!

Forgive the Android newbie comment.

I'm interested in installing a custom rom on a Moto G5. I've heard that Lineage is my only option, but also heard that they don't have a great history of security updates.

Are there any other options out there?

Thank you!
