3. Extend and Enhance Your Phone > Manage Your Phone’s Memory

Manage Your Phone’s Memory

Store more pictures and improve the device’s performance with these memory management techniques.

A typical Nokia smartphone has between 100 KB and 12 MB of built-in memory. This memory holds everything from applications and media files to messages and dynamic data created by applications at runtime. Optimizing how this memory is used will let you store more data, run more applications, and improve the general performance of the phone. In this hack, I’ll check out some cool memory management tips.

Use the Memory Card

To expand the memory space available on the device, you can install a flash-based MMC card. The size of an MMC card can vary from 32 MB to 2 GB—depending on your encoding settings, 512 MB and larger cards should be sufficient for hours of movies or digital music (see “Play PC Video Clips on the Phone” [Hack #71] , “Play DVD Movies on the Phone” [Hack #72] , and “Play Digital Music” [Hack #74] for information on how to play video and music on your phone). Most Nokia phones, such as the Nokia 6230, 3650, 6600, and 6620 smartphone, support the standard MMC cards you can buy from any electronics store. Newer Nokia phones, such as the Nokia 6630, 6670, 6681, and 6682 phones, support only a Nokia proprietary MMC format known as Dual Volt Reduced Size MMC (DV-RSMMC). The DV-RSMMC card is slightly smaller than the regular MMC card, but the former is more difficult to find and is more expensive. You should read your owner’s manual or the phone specification on Nokia web sites to find out exactly what MMC card format your phone supports.
