support and Handwriting recognition.

Popularity

P990 was adopted for business and personal use. Quickoffice comes pre-installed with the firmware itself. New features like Business card scanner and Front Camera attracted many consumers.

Problems

• New interface

P990 was the major smartphone device launched after P910. It had the latest UIQ user interface 3, which was completely incompatible with previous device applications, such as those of the P900 and P910, so new applications had to be written. Hence, the device did not have as many applications as older devices had.

• Less RAM

The major issue of P990 was RAM, which was much less (64 MB), of which device used 48 MB in start up (OS) and only 16 MB was available for the user. This caused the phone to work slowly and crash frequently. Running multiple applications simultaneously was not possible due to lack of sufficient RAM. The latest update increased the available RAM, which solved most of the problems.

• Network hang

Network hang is the most prominent problem seen on P990. When the phone is kept idle for a certain time, the signal gets dropped. Only restarting the phone solves this problem. During the network hang, the phone seems perfect, but SMS and calls are dropped.^{[citation needed]}

Latest firmware

Sony Ericsson updated the firmware,^[when?] which made OS reduce its size up to 2 MB and gave the user 17 MB of memory to use. There were improvements seen in the phone after the software update. The phone seems stable after the latest update.^{[citation needed]}

The latest firmware is R6E28 of both Generic World 1 and Generic World 2. Lot of issues were addressed since some branded phones were not allowed to update. It was then possible to change the

of the phone with the use of third-party software like XS++.
