Starting September 2026, Google will regulate the sideloading of apps through APK files on certified Android devices. Users will need to pay a fee, agree to terms and conditions, provide government identification, upload evidence of the developer's private signing key, and list all application identifiers. There are three methods for sideloading:
1. Sideloading from verified developers, requiring a verification process.
2. Sideloading from developers with limited distribution accounts, allowing sharing with up to 20 devices without ID or fees.
3. Sideloading from unverified developers, which involves enabling developer mode, confirming the user is not being scammed, restarting the phone, waiting 24 hours, and confirming identity through biometric authentication or device PIN.
These changes aim to enhance security and reduce scams while still allowing some flexibility for developers.
