Out of the box, your Android device simply allows you to install apps from a single source: the Google Play Store. To get software from anywhere else, you take to enable installation from third-party sources and take the risks that come with it.

This leaves security-conscious Android users and developers with a dilemma. Do you take a situation where Google is your sole supplier of apps, or do you open yourself up to content from elsewhere, along with potential threats?

It's a decision simply you tin can make. Here'due south some background that may help.

First, What Am I Talking About?

Maybe I'm moving also fast. Here'southward a quick way to become defenseless up.  Get to Amazon and download Amazon Underground. When y'all click on the APK (Android Parcel), you volition see this warning.

To do annihilation about this, y'all have to become to Settings > Security and flip the toggle next toUnknown sources. This will enable y'all to install apps from sources other than the Play Store.

Now you can install the APK y'all downloaded and proceeds admission to Amazon Underground.

Why Practice Apps Only Come from the Play Store by Default?

The like shooting fish in a barrel answer is to say that this is how Google makes money off Android, which information technology provides equally an open source operating organization for manufacturers and custom ROM makers to do with what they please. Google gets thirty% of the money when you buy something from the Play Shop.

But there's much more to this decision than profit motive. Pumping all software from a single, trusted source is a manner to keep devices secure. Developers create apps and upload them to the Play Store. Google checks them for viruses, malware, and anything else the company would consider malicious. And then information technology allows that app and updates to laissez passer through to users. Out of the box, devices can only become affected past bad apps if the code manages to featherbed Google's safeguards.

With this barrier removed, any software can run on your device. Now the responsibleness is on you to make certain you don't install anything from an unsavory source or accidentally click a link that manages to sneak something onto your organisation.

This situation has proven difficult for many people to grasp, and information technology's what led Windows to be the security nightmare it was known to be for many years. How could users tell a good .exe from a bad i? This ultimately led to the rise of anti-virus software and a computer security industry built around protecting users from online threats. Even with Windows 10, users have to exist proactive about their security.

Limiting downloads to primary app stores is office of the reason the mobile security landscape is a unlike story.

Why Would I Want to Get Apps Elsewhere?

Assuasive software to come up from sources other than Google Play has practical and philosophical benefits. Someone who doesn't have much money to spend on apps may appreciate that Amazon allows users to get unlimited admission to some software via Amazon Underground.

Others may like paying a price of their pick to get collections of games for inexpensive from Humble Bundle. A person who only wants to install free and open source software may prefer to download apps from F-Droid.

As long as the Unknown sources option remains unchecked, y'all tin't get software through whatsoever ways other than the Play Shop. If an app yous similar isn't in that location or gets removed, you're left without access. If you similar Android but don't desire to tie your phone to a Google account, you too are out of luck.

If you know an update is out, but the Play Store hasn't nonetheless pushed information technology to your device, all you can exercise is wait. And even if you desire to get software from the Play Shop just accept to download the APK manually to get around regional restrictions, you lot won't be able to install it without enabling access to unknown sources.

Then there are the privacy implications of getting all of the software yous use on your phone from a single identify. Your Google account has a tape of every app y'all've ever downloaded to your phone and, if you're not new to Android, your phone before that. Your account shows how many devices you own, what they are, and what software is installed on each.

This data is also connected to the same Google account that handles your email, your Hangouts messages, your YouTube viewing history, and the physical location of your phone at all times since you lot've bought it.

If giving Google that much information leaves you feeling uncomfortable, you can limit how much data the company stores. You can as well cut dorsum on how much data your Android device shares in the first place.

Is Allowing Installation from Unknown Sources Actually That Unsafe?

I would be lying if I said allowing software installation from unknown sources doesn't open you up to extra risks — it does. Malware lurks in unofficial app stores that lack the security measures you discover on Google Play.

But for the almost part, dangerous apps are easy to avert. Stick to major app stores or repositories that y'all know you can trust. Don't install APKs unless you tin verify where they came from. Avoid suspicious links the aforementioned way you would on a PC.

The same practices that keep you safe on your reckoner are important to keep in listen on your phone or tablet, especially when apps can come up from anywhere.

Should You Flip That Switch?

That depends on the kind of user you are. People who know how to avoid viruses on Windows should be able to handle themselves on Android just fine. But if you or a family unit fellow member take a hard time understanding what bad software even is, so you're probably better off leaving things as they are.

It's the single easiest thing you lot can do to keep your device safe. Most apps are available on Google Play, fifty-fifty if they may not always be every bit inexpensive every bit they are elsewhere.

That said, that isn't how I use my phone.

Simply that'due south me -- what about you? Do you install apps from unknown sources? What behavior would yous recommend new users adopt? This question affects developers and users alike, then share your opinion in the comments beneath.
