Just because an app isn’t available from the Google Play Store doesn’t mean it’s not available at all—you can effectively install non-Play Store apps on any Android phone, tablet, or other device by enabling one simple toggle. This practice is called “sideloading.”
Why would you need to do this? After all, most of the applications you want are more than likely in the Google Play Store. But there are occasions when even these “official” apps aren’t available for some reason—maybe they’re restricted in your region, not compatible with your phone, or some other equally as unimportant third thing. In any of those cases, you may want to sideload the app onto your phone. One of my favorite apps, Skitch, was discontinued a few years ago, but the old version still works. So I sideload it. It can also help you get the latest and greatest version of an app if the latest update is rolling out in stages.
Before we get started on how to do it, however, let’s first talk about why this setting is disabled by default, and the security implications you could potentially face by allowing your phone to accept installations outside of the Play Store.
Now, you can select any of the two options (Sideload apps and Developer Mode) to install apps from outside of the Windows Phone Store. These are the simplest method to enable Developer Mode and sideload app on Windows 10 PC as well as Windows 10 for mobile.
Basically, when you allow any application to be installed on your phone, you’re essentially bypassing the security protocols that are enabled in the Play Store—the stuff Google does behind the scenes to make sure all the apps you install from the official channels are safe for you, your phone, and your data. That is, of course, your call—that’s why there’s a toggle to allow other apps to be installed, after all.

But that brings me to another point: if you’re going to install apps outside of the Play Store, make sure they’re from a trusted source like APK Mirror. This is absolutely paramount if you want to make sure your stuff stays safe. There are a lot of malicious people/websites/etc. out there that want nothing more than to hijack your data, so if you’re going to slideload apps, be smart about it. If you pick your sources correctly, you can easily be just as safe installing these apps as the ones from the Play Store.
Lastly, it’s worth noting that Google changed how sideloading apps is handled on Android 8.0, so we’ll break things down into two sections below: one for Android 7.0 and below, and one for Android 8.0.
Like I said earlier, Google changed how sideloaded apps are handled in Oreo. Instead of having one universal setting to simply install unofficial apps across the board, “unknown sources” is now allowed or disallowed on a per app basis. For example, if you want to install things from APK Mirror, you’ll have to allow Chrome to install apps from unknown sources. For those interested, we have a more indepth explanation of the change here.
We’re going to use Chrome as the example here, but the process will be the same for any app you’d like to allow application installs from.
Note: Not all apps have this ability—it’s part of the code, and Android will only offer the option for apps that have the ability to download and install applications.
The option to allow sideloading apps can be found in a couple of different places, but the easiest way to handle it is from a “universal” setting that will show all apps that have this option available to them. Start by pulling down the notification shade and tapping the gear icon.
From there, tap on “Apps & Notifications,” then expand the Advanced menu.
Choose “Special App Access.”
The bottom option here should be “Install Unknown Apps.” Tap this.
All apps that have the option available to download and install applications will be listed here. Again, we’re using Chrome in this example, but you can select the app you’re trying to allow.
Once you open the app’s options, a simple “Allow from this source” toggle needs to be ticked. Turn that on, and you’re done.
I know, that was a bit of a long-winded explanation, but it’s important. In all actuality, the process is super simple. Pull down the notification shade and tap the gear icon.
From there, scroll down and tap on Security.
Scroll down this page until you see “Unknown Sources.” That’s your setting—toggle it to on.
A warning will pop up letting you know what you’re getting into. If you’re cool with that, tap OK.
Now you’re ready to sideload any app you want. All you need to do is find the APK and download it to your device—Chrome will usually offer a warning letting you know that this type of file can be harmful, just tap OK to accept that and start the download.
Once it’s finished, tap on the download notification to install the app. A popup will show up asking if you’d like to install it—just tap “install.” Let it do its thing and you’re done!
READ NEXTSideloading is a term used mostly on the Internet, similar to 'upload' and 'download', but in reference to the process of transferring files between two local devices, in particular between a computer and a mobile device such as a mobile phone, smartphone, PDA, tablet, portable media player or e-reader.
Sideloading typically refers to media file transfer to a mobile device via USB, Bluetooth, WiFi or by writing to a memory card for insertion into the mobile device.
When referring to Androidapps, 'sideloading' typically means installing an application package in APK format onto an Android device. Such packages are usually downloaded from websites other than Google play, usually through a computer. Sideloading of apps is only possible if the user has allowed 'Unknown Sources' in their Security Settings.[1]
When referring to iOS apps, 'sideloading' means installing an app in IPA format onto an Apple Device, usually through the use of a computer program such as Cydia Impactor [1] or Xcode or on the actual device using a Jailbreak method or using a signing service instead of through Apple's App Store. On modern versions of iOS, the sources of the apps must be trusted by both Apple and the user in 'profiles and device management' in settings; except when using jailbreak methods of sideloading apps.
The term 'sideload' was coined in the late 1990s by online storage service idrive.com as an alternative means of transferring and storing computer files virtually instead of physically.[2][3] In 2000 idrive applied for a trademark on the term.[4] Rather than initiating a traditional file 'download' from a website or FTP site to their computer, a user could perform a 'sideload' and have the file transferred directly into their personal storage area on the service. Usage of this feature began to decline as newer hard drives became cheaper and the space on them grew each year into the gigabytes and the trademark application was abandoned.
The advent of portable MP3 players in the late 1990s brought sideloading to the masses, even if the term was not widely adopted. Users would download content to their PCs and sideload it to their players.
Today, sideloading is widespread and virtually every mobile device is capable of sideloading in one or more ways.
Sideloading has several advantages when compared with other ways of delivering content to mobile devices:
Sideloading also has disadvantages:
Sideloading over a USB connection was standardized by OMTP in late 2007.[6] Until this time, mobile phone manufacturers had tended to adopt proprietary USB transfer solutions requiring the use of bundled or third party cables and software.
Transfer performance of USB sideloading varies greatly, depending on the USB version supported, and further still by the actual engineering implementation of the USB controller. USB is available in Low-Speed, Full-Speed, and Hi-Speed levels, with High-Speed USB transferring up to 480 Mbit/s (60 MB/s). However, the majority of mobile phones as of the time of writing of this article are Full-Speed USB. Of the mobile products supporting USB 2.0 Hi-Speed, the actual sideloading performance usually ranges between 1-5 MB/s. However, the popular BlackBerry mobile phones by RIM and the iPods by Apple distance themselves at higher performing speeds of roughly 15.7 MB/s and 9.6 MB/s, respectively.[7]
Bluetooth’s OBEX/OPP profiles allow for file transfer between a PC and a mobile device. Using this option is slightly more complicated than using a USB connection as the two devices have to be paired first. Also, unlike the familiar drag and drop that is usually available via USB, Bluetooth implementation is specific to the Bluetooth transceiver and drivers being used.Files that are sideloaded to mobile devices via Bluetooth are often received as messages, in the same way that SMS texts would be received. While these files can be saved to any storage medium, their initial location is the handset’s internal memory. As such the limitations of the internal memory have to be taken into account before beginning the sideload.
Sideloading via a memory card requires that the user have access to a memory card writer. Audio and video files can be written directly to the memory card and then inserted into the mobile device. This is potentially the quickest way of sideloading several files at once, as long as the user knows where to put the media files.
