4x MSAA is a rendering technique used in Android devices to reduce jagged edges and improve the overall visual quality of images. MSAA stands for Multisample Anti-Aliasing, which adds more differently-colored pixels to counter the jagged edges and make it seem like a straight line. Enabling 4x MSAA on a high-end Android device can help improve the resolution and result in a better gaming experience. However, one drawback of this MSAA is that it will consume more battery life when enabled. It is completely safe to turn on 4x MSAA on an Android device. To enable 4x MSAA, one needs to go into the Developer Options of the devices Settings menu and toggle it on. It is important to note that enabling 4x MSAA does not reduce lag, which is typically caused by a slow or outdated internet connection, insufficient hardware specifications, or incorrect game settings.
