Google Adds 24-Hour Hold On Installing Unverified Android Apps

Google is rolling out an 'advanced flow' for installing unsigned Android APKs that replaces the simple 'unknown sources' toggle with a multi-step process in Developer Options: users must enable 'Allow Unverified Packages' and endure a 24‑hour security delay after reboot before the setting can be activated (temporarily or permanently). A limited free developer account will permit up to 20 device installations; for more, developers must pay $25 and provide government ID. The changes also apply to third‑party app stores, with the same verification rules, and are set to roll out to more countries in coming months. Google frames this as improved security, but critics worry it will hinder sideloading and could be exploited by scammers who buy verified accounts.
