Are you talking about the pull down menu? Top menu is the one you get with top edge swipe and pull down menu is the blueish menu you get with top to bottom swipe inside the screen.
You can train by swiping from the top edge but not lifting your finger. If the menu shows up, then you are in the middle and if it starts showing the home view, then you are about to close the app. You can cancel the action by moving your finger back up.
Give it a week or two and you get pretty used to the SFOS swipes.
That is probably a can of worms that Jolla don’t want to open. I think there is some kind of patch or app to alter how some of the inside of screen swipes works in AAS.
JP2601 locks down the phone if you double press the Power Button and the phone isn’t locked already. The phone should vibrate and next time you try to open it, you need to either enter the PIN or provide fingerprint.
You might find similar workarounds to some of the issues from custom Android ROM-forums and adapt those, but this forum is the best for the SFOS specific solutions.
It is a good practice, but after you spend a while here you learn kinda who is who of the most active users and you can gauge your trust to their solutions based on that. You can also always ask people to explain what the commands do, or use search engines to find man pages etc.
For these specific commands, you can read Banking apps on Sailfish OS - #123 by myjolla_ph and maybe next 20-30 messages (there are some posts not related to these commands in between the relevant messages) to see it isn’t any malicious script k1dd13 1337 h4x0r stuff and even some of the Jolla staff has commented on it
Basically OP Mobiili made a change about year and half ago that prevents the app from starting in AAS, unless you change the process trace setting from the default setting to less restrictive. The first command saves that setting to a file that makes the change persistent between boots and the second command enables the setting now. Alternatively for the second command you can just reboot the phone.
