VMOS Review – Best Samsung Knox Alternative in 2019?


VMOS, an alternative to Samsung Knox is an application available for free on Google Play. VMOS is a virtual machine (VM) based app. You can call VMOS an emulator or apps cloner. We have seen these kinds of technologies in Samsung devices (Samsung Knox). VMOS is much more than Samsung Knox. Well, this is not a comparison, so I’ll move towards what is for you in this article. The article covers VMOS review in 2019. We’ll be going through functionalities and what you can get by installing this app. We will also go through some of the issues I encountered while testing.

What is VMOS

As mentioned, VMOS is apps cloner. It enables a separate OS on your Android device. The newly installed OS behaves differently than the already installed one. The app (emulator) comes with a few services already installed including Google Play, browser, an import apps manager, etc. You can import the already installed apps on your device or install different apps from Play Store.

Storage and installation

The installation space is over 320 MB while it occupies over 1.2 GB of storage after installing completely. Once, it is downloaded from the Play Store, it takes some time to install the internal components. It can take up to 10 minutes for the app to fully install.

Interface and features


The next part of the VMOS review is the interface. The interface is like a new Android device. The installed Android version is Android Lollipop which is reasonably old now. Down the bottom, five app icons. A floating icon which can be placed on the edge is the VMOS settings pop-up. The pop-up includes minimize, tasks manager, restart VMOS, home, and notification options. You can also swipe from the top to open the notification panel. Swiping from the top can sometimes open the built-in notification panel, so you’ll have to be careful there.

As the app has the root access, the app can change device settings including Bluetooth and WIFI. The settings menu comes with the resolution, floating window, virtual button settings, and the system settings options. The system settings, of course, contain the device settings.

Another great feature is installing and importing applications. I have already talked about using dual WhatsApp using third-party apps, but this is something high level with so many customisation options. You can already import the installed apps or go to Google Play to download some other apps to start creating a separate place for work stuff.

Floating window


The floating window is part of the VMOS review because it’s something quite unique. When the emulator is minimised, a floating option displays on the screen. The option opens the pop-up screen of the app. From there, you can open the app, mute the volume, rotate the screen, and pin the pop-up window. With the pin option, the floating window will be visible until you manually close it. Unfortunately, there isn’t an option to power off the OS with that floating window option. Although, you can end the task from the manager to turn off the emulator.


Well, there is always something good and bad. We have already discussed the good features, let’s talk about the negative effects of the app in the final part of the VMOS review.

  1. The app takes an enormous amount of storage and because it is based on VM, the apps you install and the media you add will be saved in the storage.
  2. The app lacks some of the core apps such as the camera.

VMOS did not lag or froze, which indicates that the app is well programmed, but it also depends on the device, remaining storage, and memory.

Why do I need VMOS app?

Well, if you don’t want to carry two devices, you simply can’t afford the second one, or you have a dual sim phone and you want to use a separate OS for the other SIM, then VMOS is the right application for you. You can give it a go and see if works for you.

In conclusion

Here is the end of the VMOS app review. Although Samsung Knox and VMOS have the same features, there are several features which make them different. For non-Samsung users, VMOS can be a great replacement. Anyway, I hope the article helped. Thanks for having a read. Have you tried VMOS yet? Have you tried any of the VM based OS applications?
