Android Memory

As time goes along, we tends to load a lot of apps in our Android. At times, you will suddenly gets message "out of memory". Even with the addition of 16GB of sd card, it still keep popping up the same message. What is the problem?

Actually, there are four types of memory that is available in Android.

1. Phone Ram. This is the place where all your apps run.
2. Phone Rom. This is the default place where your apps are stored.
3. SD Card Ram. This is the additional memory where apps are stored and some times use for running.
4. SIM card memory. This is generally used for phone number storage.

Rams are essentially the place where your program is run. Unfortunately, unlike PC and Laptop, this area of memory is not user expandable. Older phones generally have much smaller Phone Ram. This will prevent some apps from running.

Even with plenty of Ram, you will still find "out of memory" message appearing when you try to install apps. This is largely due to the fact that all programs has to be stored in Phone Rom. Despite the fact that in Android 2.2 (Froyo) onward, many apps can be stored in SD Card. However, it still uses some Phone Rom to register its presence. That is to say, every program uses some memory in Phone Rom. New phones has now greatly increased this memory. While older phones generally have much less. The number of app that could be installed is thus limited by this memory. Again this memory is not user expandable.

SD Card memory are generally used to store photos. Many apps uses SD card to store their app data. It is good to install as much memory as possible. Even when the hand phone dies, your data will not be lost. Obviously if your SD Card is damaged, everything goes with it. It is always good to save the data in SD card to computer.

SIM card are generally not use for Apps. It is the place to store phone numbers. However, most phone also stores the phone numbers in Phone Rom. It ends up that you may get 2 same number appearing in phone list. Always try to store phone numbers in SIM card. Should you change the hand phone, your phone number will not be lost. Generally, newly added numbers usually get stored in Phone Rom.

SIM card memory does not have the facility to store other phone number related information than the Phone Rom. You should weight your preference as to what you want to do with the number. If you are the type that stores much more information than just phone numbers, then you should store it in Phone Ram. You should always keep a copy of your client information in PC so that you could transfer the information to new phones.
