Yt4.be provides a simple offline screen for checking the maintenance build installed on an Android device. The status panel displays the target Android API level and version code. Tap "Check build status" to confirm that the installed build is ready. The check runs entirely on the device and does not download files or connect to any server. The app has no account sign-in, ads, subscriptions, background services, or device permissions, and it does not collect personal data.
Check the installed version, Android target level, and build readiness offline.
