This is an old problem of SFOS, I had it also for many years… but since the last update to SFOS 3.3.0.16 it is much better than before but not yet fixed completely.

Was your phone plugged to the charger as you tried to switch it off?
Just now I tested to switch off my phone to see what happens. Result is:

If the charger is plugged in, then the phone shuts down and then reboots.
If the charger is disconnected, the phone shuts down and stays off (does not reboot)

As said, this is an old problem and it means not, that there is a major error. You can confidently ignore this, and if you really want to switch off the phone, then unplug the charger.

It happens even if phone is not being charged. I haven’t found any consistency. But when aptoide is installed it seems more frequent.

In my experience it might be related to touching the fingerprint sensor during shutting off. Moreover this is a known issue, see https://together.jolla.com/question/217870/bug-random-reboots-when-turning-off-sony-xperia-10-plus-and-xperia-10-with-sailfish-30114/

It is not caused by touching fingerprint reader. I also thought it is caused by this. It is very annoying and would be nice if there is some workaround or if Jolla aknowledges this issue.

Not an answer, but a workaround to be able to switch off immediately: I’ve noticed switch off succes is 100% when the phone is locked: lock phone => press and keep powerbutton untill the Goodbye! appears.

Unfortunately this doesn’t work for me. This is very annoying. I even reflashed the device but it is still the same. Is there any way to let Jolla know?

Also been happening to me. Jolla should, theoretically, know about it by it being posted here, (but they wouldn’t care about me, since my device is unofficial, so I’m glad you brought it up). I am able to power off by Sony built-in button combination, (hold power and volume up for 8 seconds), but that’s only if the phone is unplugged. Any time there is a cable connected, it always reboots. I will test with the workaround mentioned above…

For me it worked to type init 0 in a terminal window.

This problem happens to me, too.
“shutdown now” in terminal seems to work.

Jolla is aware of this. There is an internal bug about this. The problem hits some devices but not all (like can bee seen in this thread). The reason for the issue seems to be deep in the system. It is not easy to fix in Sailfish but we will try.

But the forced power down should work for all:

  • press both Power and VolUp keys down at the same time
  • keep them down until you feel the vibrator play shortly 3 times (the is one short play before that).
