How to Find Hidden Wi-Fi SSID on Android — Step-by-Step Guide
Immediate recommendation: open Settings → Connections (or Network & internet) → choose Add network / Add new connection and type the exact network name, including correct capitalization and any spaces or symbols; select the matching security protocol (WPA2‑PSK or WPA3‑SAE if available), enter the passphrase, then save and connect.
If the network does not appear in the scanner list it means the access point stopped broadcasting its name, so automatic discovery will fail. Use the manual-add flow and set the authentication method explicitly; mismatched security (for example entering WEP when the router uses WPA2) produces repeated authentication errors. For dual-band routers try both the 2.4 GHz and 5 GHz options if the UI offers a band selection.
To confirm the correct network identifier and settings check the router label or its administration page (access via wired link or a device already connected). When manual entry still fails, enable location services and grant the network-scanning permission to the wireless module – some devices block passive scans without that consent. If you prefer a diagnostic approach, run a trusted network-scanner app (grant only the permissions it requires) to read broadcast channels and BSSID/MAC addresses; use those values to verify you are targeting the proper access point.
Security notes: do not attempt packet-capture or cracking to reveal a concealed name or passphrase. Only connect to networks you are authorized to use. If you must use a public or untrusted network, protect traffic with a VPN, keep the device patched, and avoid sensitive transactions until a secure connection is confirmed.
Preflight: Verify Android Version and Permissions
Immediate action: check the device API level – if API level ≥ 33 (OS 13), require android.permission.NEARBY_WIFI_DEVICES; if API level < 33, require android.permission.ACCESS_FINE_LOCATION or android.permission.ACCESS_COARSE_LOCATION plus system location enabled.
- Confirm OS version (visual): Settings → About phone / About device → Software information → Version or Build number.
- Confirm OS version (ADB): adb shell getprop ro.build.version.sdk (returns SDK int), adb shell getprop ro.build.version.release (returns release string).
- Check app runtime permissions (UI): Settings → Apps → [Your app] → Permissions – ensure the correct permission above is listed as Allowed.
- Check app runtime permissions (ADB): adb shell pm check-permission
android.permission.ACCESS_FINE_LOCATION (or android.permission.NEARBY_WIFI_DEVICES); output will indicate granted/denied. - Grant permission via ADB for testing (requires app debuggable): adb shell pm grant
android.permission.ACCESS_FINE_LOCATION (or android.permission.NEARBY_WIFI_DEVICES). - Verify system location toggle: Settings → Location (must be ON for API < 33 scan results when location permission is used).
- If scans must run in background, confirm android.permission.ACCESS_BACKGROUND_LOCATION is requested and granted on API ≥ 29 when applicable.
- Check battery/optimization restrictions: Settings → Apps → [Your app] → Battery → Allow background activity / Unrestricted – otherwise scheduled scans may be blocked.
- Developer options: for troubleshooting, enable “Verbose logging” for wireless, and inspect logcat for scan errors: adb logcat | grep WifiScanner (or relevant tag).
Additional practical checks:
- Target SDK impact: if the app targets a newer SDK, OS permission model enforces the newer runtime rules – confirm targetSdkVersion in the APK manifest.
- Runtime flow: implement requestPermission(…) for the specific permission for the detected API level; verify onPermissionResult that consent was granted before starting scans.
- Network-scanning throttling: OS versions starting at API 28 throttle scan frequency – for reliable results test with screen-on, foreground app, and with battery optimizations disabled.
- If using third-party tools, confirm they declare and request the same permissions; mismatches between declared and requested permissions can cause silent failures.
Open Settings → About phone to note Android version
Open Settings → About phone and record the OS version (numeric release), Security patch level (YYYY-MM-DD), Build number, Kernel version, and Baseband/Radio version.
Tap Software information or Software details if About phone shows only model/status; on some vendors this section is under System → About phone. Tap the version string to reveal the full identifier; some OEMs allow long-press to copy that text.
Capture the data immediately: take a screenshot (Power + Volume Down) or photograph the screen, then save the image to Notes or cloud storage for reference. When posting logs or asking support, paste the exact strings rather than paraphrasing.
Example entries to note exactly: OS: 14, Security patch: 2026-02-05, Build: RP1A.201005.001, Kernel: 5.10.100-perf, Baseband: S9010_XX. These values determine compatibility with apps and driver-level behavior for radios and connection tools.
Optionally note Bootloader and SELinux status shown in About phone or Status; do not change boot or developer settings unless specifically instructed by support or documentation.
