NOTE:
There are known issues with the trial versions of the new Xperias, including:

• Camera is disabled
• Fingerprint detection does not work on Xperia 10 V; hence removed from the UI
• Battery status doesn’t update (it does by restarting the phone) on Xperia 10 V
• eSIM support is not yet implemented; hence the eSIM slot is disabled
• Avoid using the Flight mode as the phone loses the SIM card
• Restarting the phone may last up to 2 minutes
• Reflashing Sailfish (the 2nd time) does not work with the flashing script. Therefore, the following set of manual commands shall be used - invoke them in your Sailfish directory:
