How To: Rotate to portrait to make calls on N900

December 10, 2009 5 comments

In the very first view preview videos of the Nokia N900, we saw that in contrast to the landscape oriented OS, when the N900 is turned in portrait, it activates call mode.

Now this is particularly helpful since the N900 doesn’t have any hardware call/end keys. At best, you have to press the power button and then click “phone”.

This works when in desktop or multitask view. However, this “rotate to phone mode” isn’t activated by default.

“Launch by turning” is actually pretty slick in theory. See my quibbles of this feature at end of the post.

[Thanks to Z0l in a comment for this tip]

To activate phone mode by turning:

  • Open “Phone” mode.

  • Open Phone Settings: Click the bar at the top that says “Phone

  • Click “Turning Control”

  • Check “Launch by turning

You can set “Display orientation” to either automatic or portrait, so the screen either rotates back to landscape or stays in portrait when in phone mode.

Note, Launch by Turning required turning to portrait mode. If you’re already holding the phone in portrait and haven’t turned it, it will not activate phone mode.


  • This feature should be on by default (especially since that’s how ads portrayed it)
  • There would just be call/end keys (maybe in next Maemo phone, eh?)
  • “Launch by turning” should be much faster. There’s a slight lul of a wait of about 2 seconds. It’s not an accelerometer issue, we know that’s very sensitive/fast.
  • Since no apps take advantage of portrait yet, it might have been nice to activate “Launch by turning” in all apps. e.g. in the middle of watching youtube, need to make a call –> Turn N900 portrait –> Call mode. However new apps and new firmware may give us portrait use so it might be understandable that “launch by turning” only works in desktop/multitask view

Freeware: Coin Toss Touch for the Nokia N97/5800/5530/X6/Samsung i8910 – S60 5th Edition

CT This app is free from the Ovi Store and it simulates, well, a coin toss.

To flick the coin, it uses either the touch screen or the accelerometer. You’ll see a 3D coin resembling a penny twisting around in the “air”. It would have been nice if the speed/height/rotation was affected by the degree initial movement (i.e. strength of flick) but at the moment it doesn’t. A simple touch produces the same spins as a swipe or a wrist flick.


To download, go to the >>Ovi Store<< either from your browser or from the Ovi Store App on your S60V5 phone.
