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.

Ergo, Google has randomly made changes to the process, even blocking it from happening in 2025. 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."
