As like computers, Android also have separate reserved memory space which is named as RAM memory. It's used by Android system and apps. In other words, this is the place where system and all other third-party apps perform their work and save cached data. RAM is directly related to your phone performance. The more RAM space will be, the more fast and smooth your phone will work.

Find Android RAM memory size

Sometimes, you may want to find out the RAM memory size of your Android phone. This is what you're looking for here. Right? But before that, you should know about how this RAM works in Android so as to understand the performance of your phone. Here's a complete guide on this topic.

How Android RAM memory works?

RAM stands for Random Access Memory. As name itself speak, this memory is randomly used by phone's system and apps. When you'll use any application (say photo editor or browser), it will save its temporary files (such as images, text or thumbnails) in RAM memory. Each app needs its own space to work.

As soon as the operation is completed, app will automatically leave the RAM space and delete all its cached data. On the other hand, final data is saved in device's storage. For example, again in case of photo editor, the final edited photo will be saved in phone's Internal memory so that it can't be lost.

The RAM is never emptied completely. Every time, some apps are working in background even when you're not using them. This is the reason why you get WhatsApp and Facebook push notifications when your phone is locked. While on the other hand, there are other applications which use RAM and save its cached data in it, but never delete them after use.

That's the reason why Android phone run out of low RAM space. Due to which, it may start hanging, crash apps automatically and slow down the phone's speed and performance. To overcome this problem, you have to remove all cached data manually and force stop all those apps which are working in background.
