This Android has a very fast moving history of success and developed the mobile operating system from elementary level to very highly advance and sophisticated level of performance. To run latest Android there are some hardware requirements and latest hardware equipment like X86 and MIPS architecture. The Android needs to be having minimum 32MB of RAM but 128 MB is preferable. The first mobile phone using Android HTC Dream had 192 MB RAM and 32 MB flash memory and 200 MHz ARM architecture (ARMv5) processor. The latest Android 5.1 Lollipop at least 512MB of RAM because the minimum requirement of Android of 4.4 is 340 MB. Any device less than 512 MB RAM will not be qualified for Android operating system.
