Independent Android permission guide—not SBI or YONO banking. The permission allows one source app to request installations; it does not make the APK trustworthy. Verify first and never disable Play Protect to force an install.
Per-source permission
Allow Chrome or Files to install Yono Rummy APK?
Enable only the app that is actually opening the verified file.
Direct answer
Allow the source shown in Android’s prompt. If you tap the APK inside Chrome, the source is Chrome; if you locate it in Files by Google or Samsung My Files, the source is that file manager. Grant access only after the APK passes source, package, signer and checksum checks, complete the install, then switch that source permission off again.
The permission follows the opener, not the filename
Modern Android treats “Install unknown apps” as a per-source setting. A global “unknown sources” tutorial from an older Android version can lead you to the wrong menu. Android asks which app is handing the APK to Package Installer.
- Opened in Chrome
- Settings → Apps → Special app access → Install unknown apps → Chrome.
- Opened in Files
- Select Files by Google, My Files or the file manager named in the prompt.
- Opened from chat
- Do not grant access immediately. Save the file, verify its origin and move to the documented route instead of installing a forwarded copy.
- After installation
- Return to the same menu and turn “Allow from this source” off when you no longer need it.
Safe permission sequence
- Locate the exact file through Chrome Downloads or Files and record its size and modified time.
- Run the safe APK download checklist. A permission prompt is not a source check.
- Open the file once. Read which source Android names in the blocked-install message.
- Open that source’s settings page, enable access temporarily and return to the installer. Do not enable every browser, chat app and file manager.
- Read the requested permissions and installer identity. Stop if the package or signer differs from the verification record.
- After installation, disable the source permission and keep Play Protect active.
If Android still refuses the APK, do not cycle through unrelated source permissions. The cause may be an invalid package, incompatible Android version, signature conflict, work policy or blocked file. Use the exact error message to choose the next diagnostic lane.
Why enabling the wrong app does nothing
Suppose Chrome downloaded the file, but you later open it from Files. Chrome may have download access, yet Files is now the app requesting installation. Android can therefore ask for Files permission. This is expected and is not a reason to grant both permanently. Conversely, a file-manager permission will not authorize an APK launched directly from a browser tab.
Never treat “Allow from this source” as a safety badge. It simply changes whether Package Installer will accept a request from that app. The card-game APK remains unrelated to SBI banking, and no legitimate install step here needs an SBI password, OTP or UPI PIN.
Sources and scope
- Samsung Support: install unknown apps from a selected source.
- Google Android Help: keep Play Protect scanning active for sideloaded apps.
- Android Developers: PackageInstaller result and failure categories.
Menu paths vary by Android skin. Follow the source name in your device prompt and preserve the same verify-before-install rule.
Install permission FAQ
Should I allow both Chrome and Files?
No. Allow only the app that opens the already APK under review, and disable access after the installation is complete.
Does “Allow from this source” prove the APK is safe?
No. It is an Android routing permission. Package, signer, checksum, source and permissions still require separate verification.
