How to Check RAM in Vivo X21s

The performance of a mobile phone is determined by many factors. One of them is the size of the working memory. The larger it is, the better the device is suited for multi-tasking. There are several ways to check RAM in Vivo X21s.

Settings menu

The easiest way to do this is to use the tools built into Android. All you have to do is follow the steps below:

1. Open the settings of the phone.
2. Scroll through the list and find the section "About Phone". The size of the RAM is displayed under "RAM".

Depending on the Android version and the respective firmware, the names of the menu items may differ. The "About" section may also have other names, e.g. " About System" etc. If this method does not help you, there is another one:

1. Open the settings menu and select the tab "About phone".
2. Go to the "Software information" section, find the "Build number" line and tap it 5-10 times in a row. If all goes well, a pop-up notification will appear on your phone screen saying "You are already a developer and do not need to perform this action" (or similar).
   
3. Go back to the main settings menu and select "Developer Options".
4. The size of the working memory is displayed next to "Total memory".

Third-party programmes

In the official Google Play Shop for all Android smartphones, there are many utilities that tell you how much RAM you have. In addition, such apps often show the type of flash drive and other useful information.

For our purposes, apps like "DevCheck Device & System Info", "Device Info" and AIDA64 are suitable. Let's use the latter.

1. Go to Google Play and search for AIDA64 in the search bar.
2. Download the app and open it.
3. Click on the "System" tab. The amount of RAM for your Android smartphone is shown in the "RAM" line. A more detailed value is shown next to "Total Memory" and the free memory space is shown under "Available Memory".
   

If for some reason you are unable to install AIDA64, you can try downloading other similar programs listed above.
