Discover the secret island inside android, that's exactly the island app is about. Want to run a secret Facebook account or want to run a suspicious app? All your photos and app data remain seperate and secure when you run it in island. With hackers creating rat that isn't even detectable by an antivirus, your privacy is at risk. What makes this app really unique is that what you do inside this sandbox is not detectable by apps that are normally installed in your phone.
You can setup a safe work place where all your data is secure and seperate. It will be a good place to secure your mobile wallet.
I always check what kind of permission an app owns and sometimes some apps ask too much permissions that isn't required. That's scary.
The good part is, the Island app comes from the developer who developed the popular greenify app.
As per the developer of Island, Oasis Feng
"Island" is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted. Device-bound data is still accessible (SMS, IMEI and etc).
Isolated app can be frozen on demand for which launcher icon vanish and its background behaviours completely blocked.
Island uses the "managed profile" feature, the base of "Android for Work", to create an isolated sandbox for apps and its data.
App that you want to use has to be cloned in island and can use it just like independent app with different accounts signed in.
Reasons to have island
To run suspicious apps without compromising your valuable data.
Freeze frequently woken apps
Clone it into Island and uninstall the original one outside. Then you can freeze it to fully block its background behaviors. Remember to create launch shortcut for quick de-freezing and launching.
Prevent permission-hungry apps from accessing your private data
Sometimes runtime-permission may not be the solution, especially if the app refuses to work without certain permissions. App clones running in Island cannot access your contacts, call logs and sniff other apps outside. But SMS and location are exceptions since they are bound to device.
Use two accounts of the same app parallel
Clone it into Island and login to other account inside.
Archive rarely used apps
Hide your private apps
It's still in beta version for which you can find more info here
and there is a no root unreleased version in playstore which is a lite version of real app.
