About RAM on Android Device

The internal memory of an Android device normally refers to the Random Accessed Memory (RAM) of that device. The RAM of Android phone or Android tablet is relatively unchanged. That is to say, it keeps the capacity when you purchase the device. In general, the capacity of Android internal memory varies from 512MB to 3GB. Among which, 1GB and 2GB are the most common size of the internal memory nowadays.

Nevertheless, the Android device that produced at an early time is built with small RAM. For example, HTC Explorer that released in 2011 has only 512MB RAM; HTC HD2 has 576MB RAM; Samsung Galaxy Y series even has 290MB RAM; and Galaxy Ace has 384MB (accessible 278MB) and Galaxy Mini series also has less than 1GB RAM. Other than these mentioned Android phones, the device with 1GB or 2GB RAM may no longer meet our daily requirement.

Why Increase Internal Memory in Android?

As we know, internal memory of Android device, to a large extent, affects the number of running programs on your phone or tablet. Therefore, when you start many programs in a small internal memory device, you are likely to get the “low space in internal memory” warning. Meanwhile, to run heavy software like games, it may stop or exit the program now and then. Some system programs may not function normal as well, which will dramatically affect the user experience.

What’s more, to purchase another Android phone or tablet is costly. Then, what’s the best way to increase RAM of your Android device at a low cost?
