This morning it seems that I received a call (red led on), but when I tried to wake up the terminal, the screen remained black, I had to turn off then on again, this is the second time it happens to me.
How to undo one or two upgrades, then apply them again, I had problems during the upgrade to version 3.3.014.

If you're worried that the update didn't install correctly, you could apply the update again via command line (system downgrades aren't recommended). You need to activate developper mode in settings and set a login password.

Open the command line interface (Terminal) and enter: (this will start the update process)

devel-su (*your password*) 
ssu re 3.3.0.16 
version --dup

Then reboot the device.

Before updating also make sure no apps from OpenRepos (if you're using it) are risking the Update to fail. See: https://together.jolla.com/question/222221/release-notes-330-rokua/#222221-notification-concerning-apps-from-open-repos

If you have questions about that, please ask :)

I found a workaround.
When I move on the city, I put the phone in a case hanging on my belt.
This is when (after 20 or 30 minutes and there is messages, telegram with Alien Dalvik, not read) I take it out of the case and press the button to activate it:

- The LED changes from blue to green and flashes (as usual)
- The screen remains black.

I have detected that if I leave the terminal and wait for the LED to turn blue again, if I try to activate it again, this time it activates normally.
