X10 Dual SIM reboots instead of switching off

Thank you. This works on my X10. Conclusion for other people who have the same problem: To power off the phone - press and hold the power button till the phone switches off and IGNORE the appearing power button on the screen. Keep button pressed till phone switches off. So the phone will not reboot and remain switched off. But there remains one question: Is it a risk to damage the system this way?

Is it a risk to damage the system this way? Why would it damage the system? Isn't it just HW signal for the kernel to shutdown? At least I used to do this with my Jolla Phone and never had any problems with it.

As a temporary solution this can be good, but Jolla should really look into it. I hope in the next update they'll fix many of the small (and big) issues that affect this phone!

Keeping the power button pressed is the equivalent to pulling the power plug on a Linux PC while shutting it down. If the system at the time of power-off has completed all write operations, you are good, if not, you might break your system. It all depends on how well your system is equiped to handle such an incident. Look at Raspberry Pis, their SD card takes power-offs really bad and tend to get damaged during the process. If you mount your sd card read-only, nothing will be damaged and your system will be fine. How Sailfishos handles this type of hard power-off I don't know, but if I really have to power-off, this is currently my only way possible. Maybe one of the devs could explain how SFOS would manage a "power-outage"

Edit: fixed autocorrects

After updating to SFOS 3.3.0.16 this problem still persists. Many other problems are now solved, Thank you Jolla!

Edit June 18.: After a few reboots because of other reasons, power down by long pressing the power button works now.
