Google Tightens Android Sideloading: Unverified Apps Now Face a 24-Hour Wait

Google has introduced a new verification process for sideloading apps on Android, adding a 24-hour waiting period for apps from unverified developers. This move aims to tighten security and combat malware distribution by tying app creators to real-world identities. The process, set to roll out globally starting September 30, 2026, requires users to complete a series of steps to install unverified apps, which initially include a 24-hour wait.

The feature relies on a background service called Android Developer Verifier, distributed through Google Play Services. Users must perform this setup once on their ecosystem, with a 10-minute grace period if the setting is accidentally disabled. Apps installed via ADB remain exempt from these checks and delays. Google claims this extra step helps prevent social-engineering scams where attackers guide victims through installing malicious apps.

However, legitimate users who install software from pseudonymous developers or modding communities will face the same barriers. While Android will still allow advanced users to sideload apps through methods like ADB, the new verification system gives Google a more significant role in determining how easily unverified software can reach mainstream Android users.
