I wish Jolla can do something about the possibility of disable the device lock so dont need to reinstall for Xperia phones

For all Xperias the device lock is now mandatory (due to encryption of /home) and cannot be circumvented since version 3.3.0.16, when flashed with this or higher.
(Afair for the X10 it was then from the beginning?)

So for X and XA2 you need to flash SFOS 3.2.1.20 (or lesser) and then update OTA. This is the only way you can achieve not having device encrypted and not using a device lock code.
