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
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.
Unlike the desktop, we cannot increase internal memory (RAM) of Android device by
adding an extra RAM, nor can we expand it like expand ROM by replacing a larger SD
card. 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? Following
will show you how to increase internal memory of device on Android by partitioning
SD card. You can use this way to increase internal memory of any Android phone.

space in RAM thoroughly. Also, you can prevent some software or programs from
running at backstage. However, chances are that you’ll encounter the same issue in
the near future.
In a nutshell, you can increase internal memory using SD card for your Android phone.
The theory is, create two partitions with different file systems on the SD card. One
is FAT32 which is used as storage (ROM), and the other is EXT2, EXT3 or EXT4 that is
used to increase internal memory (RAM). This is simple yet you have to meet several
conditions and prepare some tools at the same time.
Your Android phone or tablet has to be rooted before. This is used to move
built-in programs to new space as well as authorize follow-up operations.
