Developer Mode is a hidden menu for testing and debugging — you can turn it off in Settings
Developer Mode is a set of advanced tools built into Android that let programmers test apps and access low-level phone functions. Most people never need it. If you turned it on by accident, or you're concerned about security, you can disable it in about 30 seconds through your phone's Settings app.
The steps are the same across most Android phones, though the exact menu names vary slightly depending on your manufacturer (Samsung, Google Pixel, OnePlus, etc.). The process involves going to Settings, finding the "About Phone" section, tapping a hidden counter, and then toggling Developer Mode off.
Key Takeaways
- Developer Mode is turned on by tapping "Build Number" seven times in Settings > About Phone, and turned off the same way by toggling the switch in Developer Options.
- Having Developer Mode on does not automatically put your phone at risk, but it does expose tools that could be misused if someone gains physical access to your device.
- You can turn Developer Mode off without losing any of your apps, photos, or personal data.
- If you cannot find Developer Options in Settings, your phone may not have Developer Mode enabled, or your Android version may use a different menu structure.
Steps to disable Developer Mode on most Android phones
Open the Settings app on your phone. Scroll down and tap "About Phone" (on some phones this is called "About Device" or "Device Information"). Look for an entry called "Build Number" — this is usually near the bottom of the list.
Tap "Build Number" seven times in quick succession. After the fourth or fifth tap, you will see a message saying something like "You are now X steps away from being a developer." Keep tapping until you see "You are now a developer" or a similar confirmation. This unlocks the Developer Options menu.
Go back to the main Settings screen. Scroll down — you should now see a new menu item called "Developer Options" (sometimes "Developer Settings"). Tap it. Look for a toggle switch at the top of the screen labeled "Developer Mode" or simply "Developer Options." Tap the toggle to turn it off. A confirmation dialog may appear asking if you want to disable it — tap "OK" or "Disable."
Where to find Developer Options on different Android phones
On Google Pixel phones, Developer Options appears in Settings > System > Advanced > Developer Options. On Samsung phones, it is usually Settings > About Phone > Software Information, then tap "Build Number" and return to Settings > Advanced Features > Developer Options. On OnePlus, Motorola, and other brands, the path is typically Settings > About Phone > Build Number, then Settings > System > Developer Options.
If you cannot find "About Phone" in your Settings, try searching for it using the search bar at the top of the Settings app. Type "about" or "build number" and the phone will show you the exact location. This works on Android 10 and newer.
What happens when you turn off Developer Mode
Turning off Developer Mode removes the Developer Options menu from your Settings. It does not delete any apps, photos, messages, or other data on your phone. Your phone will work exactly as it did before you turned Developer Mode on.
If you had enabled USB Debugging (a feature inside Developer Options that lets a computer connect to your phone for testing), that will also be turned off. This is actually safer — USB Debugging allows a connected computer to install apps or access files without your permission, so disabling it reduces that risk.
Why you might want to turn off Developer Mode
Developer Mode itself does not make your phone less secure just by being enabled. However, the tools inside it — like USB Debugging, mock location apps, and root access — can be misused if someone has physical access to your phone. If you share your phone with others, or if you are concerned about someone tampering with it, turning off Developer Mode removes those tools from view.
Some people also turn it off simply because they do not need it and prefer a cleaner Settings menu. There is no performance benefit to having it on or off.
If you cannot find the Developer Options menu
If you followed the steps above and still do not see Developer Options in Settings, it is possible that Developer Mode was never actually turned on. Tap "Build Number" seven more times — you should see the "You are now a developer" message appear. If it does not, your phone may use a different Android version or manufacturer skin that hides this feature.
Another possibility is that your phone has a parental control or device administrator policy that blocks access to Developer Options. If this is the case, you may need to remove the administrator account first. Go to Settings > Security > Device Administrators (or "Admin Apps") and look for any apps you do not recognize. Tap them and select "Deactivate" or "Remove."
Frequently Asked Questions
Does turning off Developer Mode erase my phone?
No. Disabling Developer Mode only removes the Developer Options menu from Settings. All your apps, photos, messages, and personal data remain on your phone. Your phone will restart or refresh briefly, but nothing is deleted.
Can I turn Developer Mode back on later?
Yes. You can turn it back on anytime by going to Settings > About Phone, tapping "Build Number" seven times, and then toggling Developer Options on. The process is the same whether you are turning it on for the first time or turning it back on after disabling it.
Is it dangerous to have Developer Mode on?
Developer Mode itself is not inherently dangerous, but it exposes tools like USB Debugging that could be misused if someone gains physical access to your phone. If your phone is always in your possession and you trust everyone who touches it, the risk is very low. If you share your phone or are concerned about physical security, turning it off is the safer choice.
What is USB Debugging and should I turn it off?
USB Debugging is a tool inside Developer Options that lets a computer connected via USB cable install apps or access files on your phone without your permission. If you turned on Developer Mode by accident, USB Debugging is probably already off. You can check by opening Developer Options and looking for the "USB Debugging" toggle — if it is off, you are fine.
My phone is frozen or slow after turning on Developer Mode. Will turning it off fix it?
Turning off Developer Mode is unlikely to fix a slow or frozen phone, because Developer Mode does not use significant resources. If your phone is slow, the cause is probably something else — too many apps running, low storage space, or a software bug. Restarting your phone often helps more than disabling Developer Mode.
