The short answer is yes, COD Mobile can run on a device with 3GB of RAM. However, you may experience lag and jitter if your device isn’t powerful enough to handle the game.
We recommend that you have at least 4GB of RAM in order to ensure a smooth gameplay experience. Additionally, you should have a powerful chipset/processor to ensure that the game runs optimally.
The more RAM and power your device has, the better COD Mobile will perform. Ultimately it is up to you to decide if 3GB of RAM is sufficient for your needs. However, we recommend 4GB of RAM as an ideal configuration for COD Mobile.
Secondly, if you have a good processor but don’t have enough RAM, it will be difficult for your device to process data and run applications. This is because the RAM or Random Access Memory acts as a bridge between the processor and the data stored in it. The more RAM your device has, the better results you get from your phone.
In addition, if your phone runs on an older version of Android, then you should opt for more RAM to experience smooth operation. This is because the newer versions of Android are heavier and require higher memory to run properly.
