One of the first things most of us do, when deciding whether to purchase a mobile phone, is take a look at the manufacturers specifications and read a few impartial reviews. Many of us are left flummoxed by confusing and unexplained terminology used, and instead rely on what we presume to be accurate, unbiased opinions. Maybe we have simply heard the hype, seen the adverts, and fallen in love with the concept. But do we really know what we are spending our hard earned cash on? Will it perform the way that we want it to?

Phone memory is becoming crucial, with sophisticated smartphones needing more and more of the precious grey matter, both to perform tasks only our home computers and laptops could handle previously, and to store all of the fixed data and programmes that make the phone what it is.

It is therefore increasingly essential to have as much internal memory as possible on android smartphones, as users are increasingly able to access and download a constantly growing amount of apps (over 200,000 android apps as is stands today). Also, with better cameras and camcorders, plus the ability to download and watch music videos and films (with the inclusion of flash), every Gigabyte of memory counts.



ROM is a portion of android's memory which consists of prerecorded, read only data that cannot be removed. It houses android's operating system, such as Gingerbread 2.3, which contains all essential software without which, the phone would not function. ROM is probably the least important memory component to consider, although the larger the android's ROM, the better, as future operating system updates may be compromised if the ROM is insufficient.


RAM is the memory available for the phone to use when running programmes. Amount of RAM determines how many programmes or apps can be open and running at the same time. The more RAM an android phone has, the more apps can be used consecutively without making the phone too sluggish. It is important to get the best RAM you can if you use your phone for gaming or apps and like to multi-task.

Internal Memory (also known as Flash memory)

Internal memory is the phones built in memory card. Internal memory is not upgradeable and so it is important to invest in the largest amount in the first instance. It is possible to find smartphones with as much as 16 GB internal memory as of today. A growing number of apps are only able to be stored on internal memory due to special permissions they require, such as; alarm clocks, calendars, virus scanners, flash player etc. Internal memory is an android smartphones most valuable memory resource.

External Memory (also known as SD card)

External memory is data stored onto an SD card, accessed by the phones card reader. Android phones accept specified memory cards, which are able to expand the phones memory by as much as; 1 Gb, 2GB, 4 GB, 8 GB, 16 GB or 32 GB, dependent on the phones predefined maximum size. External memory is a place to store all of your media, apps, contact lists etc.
