Allow only the current app
If required, grant “install unknown apps” permission only to the browser or file manager you are using, then review the setting afterwards.
Android installation task
Follow the Android decision points in order: confirm the downloaded file, review the installer prompt, allow only the source you are using and check the app after first launch.
Step by step
Android wording varies by phone maker, but the safe decision sequence remains similar.
Use the dedicated IJ7 APK Download page, confirm the browser prompt and wait until mmy.603thad.apk has completed.
Tap the completed file from the browser notification or Android Downloads app.
Confirm the displayed app identity. If Android asks, allow installation only for the browser or file manager currently in use.
Tap Install, open IJ7 once and review the logo, app identity and each permission request.
Cancel if the filename, app identity, destination or requested permissions do not match what you expected. This guide does not recommend disabling Android security protections.
Installation context
If required, grant “install unknown apps” permission only to the browser or file manager you are using, then review the setting afterwards.
If IJ7 is already on the phone, record its version and prepare account recovery before installing another file.
Stop if the installed identity or permissions look unrelated to IJ7 or to the features you intend to use.
Installation questions
Android can block apps installed outside Google Play until you allow the specific browser or file manager as an installation source.
This guide does not recommend disabling device protection. Review any warning and stop if you cannot verify the file identity.
Use the Update guide first. Compare the installed version, app identity and permissions before replacing it.
