The once-mysterious “IoT Hidden Menu” hasn’t vanished entirely, but its availability now depends on the brand, the Android flavor, and even your carrier’s firmware. Below is a snapshot of where you can still uncover it in 2025 and why some manufacturers have quietly removed it. If you’re curious about accessing this feature, understanding its presence across devices is key to navigating the iot hidden menu android.
Google Pixel (Android 15)
Pixel phones dropped the menu back in Android 13, and nothing has resurfaced in Android 15. Google’s public stance is that all necessary radio, sensor, and connectivity diagnostics live in the ##4636## testing panel and in the Pixel Repair Tool. Unless you’re on an internal engineering build, the IoT Hidden Menu is effectively gone.
Samsung One UI 7
Samsung shipped the menu as late as One UI 5.1, but One UI 6 quietly disabled most entries, and One UI 7 (Android 15) no longer exposes the dial-code trigger. Knox security teams argued it duplicated diagnostic features that already live in their ServiceMode app and posed needless tampering risk. Engineers can still sideload a debug APK to surface it, but consumer firmware blocks the dial code.
Xiaomi MIUI 16 / HyperOS
HyperOS retains a pared-down IoT section accessible via ##6484## (Xiaomi’s main CIT menu). You’ll still find BLE beacon strength, accelerometer graphs, and Wi-Fi RTT test toggles. Anything that could rewrite calibration blobs, however, is now gated behind an engineering-mode PIN only Xiaomi service centers know.
OnePlus OxygenOS 15
OxygenOS rolled the IoT menu’s useful bits into the “LogKit” app. Dial *#800# and choose Engineering Mode → IoT Test to get sensor-fusion charts, NFC field strength, and UWB ranging data on the OnePlus 13 series. Root isn’t required, but you must enable “Engineer Mode” in developer options.
Motorola Hello UI
Still the friendliest: dial ##2486##, choose IoT, and an almost untouched classic interface pops up—helpful for field technicians who handle Moto’s enterprise scanners. Just don’t flip the “Factory Reset Sensors” switch unless you really know what you’re doing.
Sony Xperia UI (Android 15)
Sony never officially branded it “IoT,” but an equivalent submenu exists inside the Service Menu (dial ##7378423##). The 2025 Xperia 1 VII keeps radio-frequency and sensor tests, yet UWB and mmWave diagnostics have moved to a service-center-only app.
Why It’s Disappearing
Security Hardening: OEMs fear that malicious apps could invoke hidden intents and tweak low-level radios.
Regulatory Compliance: Regions now require locked-down RF calibration parameters.
Simplified Support: Brands want users to run scripted diagnostics through official repair apps rather than poke around obscure menus.
Tips for Access in 2025
Use correct regional firmware: Some carrier builds strip the dial codes entirely.
Enable Developer Options: A few brands hide engineering shortcuts until “USB debugging” is turned on.
Beware SafetyNet/Play Integrity: Dial-code tinkering rarely trips it, but flashing engineering builds or Magisk modules to restore the menu can flag your device as non-certified.
Document changes: If you toggle anything, screenshot original values first—some settings aren’t labeled clearly and can’t be reset without a full firmware flash.
Bottom Line
In 2025, the IoT Hidden Menu survives mainly in Xiaomi, OnePlus, Motorola, and partially in Sony land, while Google and Samsung have folded its features into other diagnostic tools or locked them behind service-center credentials. If you’re shopping for a phone expressly to run in-depth sensor and connectivity tests, verify first whether the specific regional firmware and Android skin still lets you unlock that dial-code doorway.
