Update gets stuck at "just a moment" after downloading

Hi,
thank you all for the help. Johannes solution did the trick for 1.2.8 and setting the display timeout to 30 minutes made the 1.3.6 update happen. [quote=“Johannes, post:24, topic:16372”]
approach 2 in the help desk article.

Sadly the 1.3.6 Update brought me a new bug. Directly after the update I recognised, that I can not reach the P on the keyboard anymore. This made me install a Screen Touch Test App which showed a 5 mm area on the right site of the screen where the Touch is not working. See the attached pictures:

Is this a common error with the new update or am I the first to report it? I did a quick Forum search but couldn’t find similar errors. Seams to be clearly software/update related as I recognised it first just a few minutes after the update.

Kind regards, Andreas
