USB debugging not showing in Developer Options? Here's the fix

The universal sequence

Open Settings → About phone → tap 'Build number' seven times. You'll see a toast counting down. After the seventh tap, Developer Options unlocks.

Samsung (One UI)

Settings → About phone → Software information → tap 'Build number' 7 times. Developer options appears under Settings (root level).

Xiaomi / MIUI / HyperOS

Settings → About phone → tap 'MIUI version' or 'HyperOS version' 7 times. Developer Options is under Settings → Additional settings.

Pixel / stock Android

Settings → About phone → 'Build number' 7 times. Developer Options is under Settings → System.

Still not showing?

If a parental control or MDM profile is enabled, Developer Options may be locked. On work-managed devices, contact your IT admin.

Why the toggle hides in the first place

Android deliberately buries USB debugging behind the seven-tap Build-number gesture so casual users can't enable it by accident — it's a power-user setting that lets a computer take real control of the device. Once Developer options is unlocked it stays unlocked, so you only do the tap dance once per phone. If the whole Developer options menu vanishes after an update, the unlock simply needs redoing; your other settings aren't lost.

Frequently asked questions

I enabled Developer options but USB debugging is greyed out — why? A work profile, MDM policy, or parental-control app is blocking it, or the phone is in a restricted/retail mode. On a personal device, removing the managing profile restores the toggle.

Do I have to re-enable USB debugging after every reboot? No. Once set, it persists across reboots. If it keeps switching off, a security or "auto-revoke permissions" feature is resetting it.

Will turning on Developer options harm my phone? No. Developer options is a standard built-in menu; simply unlocking it changes nothing until you toggle a specific setting like USB debugging.

Where exactly is Build number on my phone? Usually Settings → About phone, but Xiaomi/MIUI puts it under "All specs" and Samsung under "Software information". Tap it seven times to unlock Developer options.
