Operating System and Performance
Running on Symbian 9.1 with UIQ 3.0, the P990 was at the forefront of the smartphone OS ecosystem. Symbian was revered for its multitasking capabilities and efficient use of hardware resources. The device is powered by a Philips Nexperia PNX4008 processor clocked at 208 MHz—a specification that may seem minimal today, but was adequate for basic tasks in its era. Users had access to 64MB of RAM and 128MB of flash memory, with the option to expand storage through a Memory Stick Duo Pro card.
