Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Google has changed the way sideloading works on Android.You must confirm you're not being coerced into doing so.There's also a 24-hour waiting period before the setting is available.Sideloading apps on Android is the process of installing an app from a downloaded APK file. Think of it like installing an app from an .exe or .msi file on Windows. You download the file, tap on it, and wait for it to install.That process has been around for quite some time. However, Google has, on and off, put the kibosh on it because of security concerns. Those concerns are legitimate. You could download an APK package from some unknown website that contains malware, and the next thing you know, your phone is compromised, your data is stolen, and things go south very quickly.

In a surprising turn of events, Google has opened the process back up, with the caveat of a restart and a waiting period of 24 hours. This news came via a Reddit post, where Google mentioned the name of the process, Advanced Flow. In the description of the process, Google states, "This flow is a one-time process for power users -- but it was designed carefully to prevent those in the midst of a scam attempt from being coerced by high pressure tactics to install malicious software. In these scenarios, scammers exploit fear -- using threats of financial ruin, legal trouble, or harm to a loved one -- to create a sense of extreme urgency." How Advanced Flow works What you'll need: The process is still simple; it just takes a bit longer at first. Essentially, you enable the ability to sideload apps, authenticate via your screen lock, confirm that you aren't being coerced into sideloading apps, restart your phone, wait 24 hours, and then decide if you want to allow installation from unverified developers for seven days or indefinitely. Note: If you go with seven days, you don't have to go through the waiting period when you want to re-enable it. Here are the specifics of the process.

How to sideload Android apps After you've taken care of the above, you'll be able to sideload apps on your Android device. 1. Download an APK file Go to a reputable site and download an APK file. Then, open the Files app and tap the download. 2. Disable Advanced Protection You'll be prompted that your device is protected by Advanced Protection. Tap Settings, and then disable Advanced Protection. 3. Install the app Once you've disabled Advanced Protection, open the Files app, go to Downloads, and tap on the downloaded APK file. You will then be prompted to install the app. 4. Re-enable Advanced Protection This next step is important. After the installation, go back to Advanced Protection (open Settings and search for Advanced Protection) and enable it so you're getting the most protection possible for your device. Be careful I would be remiss if I didn't give you this word of caution: Be very careful about installing APK files from unknown sites. Two reputable sites are APKMirror and F-Droid, but those sites offer XAPK files, which can only be installed via their respective apps. To find pure APK files, you can go to Uptodown (which is also reputable). Even then, when you find an app you want from either site, do a bit of searching to make sure the developer is legit and can be trusted.
