Applications implemented for S60 3rd Edition and later should scale to all of the supported resolutions. S60 devices may use one of the following screen resolutions:
NHD Portrait (360x640)
NHD Landscape (640x360)
QVGA Portrait (240x320)
QVGA Landscape (320x240)
The scalability requires developers to take different screen resolutions into account when creating their application designs. The emulator supports this by providing the needed resolutions.
