Speed Up Your Phone Camera
Relatively newer Nokia phones, especially ones with a mechanical shutter and an autofocus lens (N73, N95 etc), are the most affected in this regard. You must've observed how the screen orientation lazily changes from Portrait to Landscape as soon as you slide open the lens cover to get the camera ready.
However, here's an amazing tip that'll really help speed things up while using your phone camera, making it much snappier than ever before.
The trick is to get the phone in Landscape mode before you're about to use your camera.
Apart from being less taxing for the processor, there also won't be any significant delay between switching screen orientations and the camera will be ready for action in no time! The results speak for themselves. Notice how fast the phone response is when you start the camera from standby/sleep in Landscape mode.
Changing screen orientations isn't much of an issue too, especially with freeware apps like the excellent RotateMe v1.21, available here for the N73 and N80. Once you start RotateMe, simply tap 'Rotate' from Options to switch to Landscape mode (and vice versa).
Another advantage is the fact that Landscape mode isn't a hassle and is quite useable, although initially you'll feel otherwise due to the awkward position you'll be holding your phone in. Furthermore, it's compatible with a plethora of apps and you could, for instance, use it with the excellent free Sega Genesis Emulator, Picodrive, to play a quick game or two of Street Fighter II Turbo or get a much better view of the www while browsing the internet...the possibilities are endless :)
So, next time you're at a party, be sure to have your phone in Landscape mode before you start snapping away!
