I recently bought an Xperia XA2 Plus and flashed it with the latest Sailfish OS.
I had noticed in Jolla's documentation that it wasn't necessary to update the phone to Android 9 (Pie) before flashing, but didn't understand this to mean I couldn't flash Sailfish OS if the phone was running Pie. I also didn't appreciate that running Pie meant the phone really needed the Sony vendor binaries for that Android version; I simply followed the Jolla installation instructions slavishly, selecting Sony binary 16 because of Jolla's advice about 5GHz wifi performance.
When I finished flashing the phone, everything worked except the fingerprint reader. This initially puzzled me, because I'm sure Sailfish OS 3.2 claims to support fingerprint unlocking for the XA2 phones. I've been wondering whether the fingerprint failure was due to installing against the wrong Android version. Now I have no idea.
It would be nice to have the fingerprint reader working, and I wonder whether it's worth re-installing Android 8 Oreo and starting again. But everything else is working so well I'm loathe to do this.
If it should work, then there's something wrong/missing in the installation package or something else has gone bonkers, did some digging based on another thread here https://together.jolla.com/question/193449/sailfish-fpd-wont-start-xperia-x-fingerprint/:
