Developer Mode is a hidden settings menu that lets you change how Android works under the hood
Developer Mode gives you access to tools meant for people building apps — things like USB debugging, performance monitors, and the ability to install apps from sources other than the Google Play Store. Once you turn it on, it stays on until you manually turn it off. If you enabled it to test something or follow a tutorial, or if someone else turned it on your phone, you can disable it in about 30 seconds.
The steps differ slightly depending on your Android version and phone manufacturer, but the core process is the same: you go into Settings, find Developer Options, and toggle it off. Your apps and data stay exactly as they are — turning it off just hides those advanced tools again.
Key Takeaways
- Developer Mode is turned off by going to Settings, then About Phone, then tapping Build Number seven times, then returning to the main Settings menu to find Developer Options and toggle it off.
- The exact path through Settings varies by phone brand — Samsung, Google Pixel, and other manufacturers organize menus differently, but the Build Number tap sequence works on all of them.
- Turning off Developer Mode does not delete your apps, messages, photos, or any other data on your phone.
- If you cannot find Developer Options in Settings after enabling it, restart your phone and check again — sometimes it takes a moment to appear.
The step-by-step process for most Android phones
Open Settings and scroll down to find About Phone (on some Samsung phones it is called About Device). Tap it to open a menu showing your phone model, Android version, and other system information.
Look for Build Number in that menu. Tap it seven times in a row. After the third or fourth tap, you will see a message saying "You are now X steps away from being a developer" — keep tapping until it says "You are now a developer." This unlocks Developer Options in your main Settings menu.
Go back to the main Settings screen. Scroll all the way down and look for Developer Options (on some phones it appears under System or Advanced). Tap it to open the Developer Options menu. At the very top, you will see a toggle switch labeled Developer Mode or just Developer Options. Tap the toggle to turn it off. The menu will close or dim, and Developer Options will disappear from your Settings menu.
Where to find it on Samsung phones specifically
Samsung phones organize Settings slightly differently. Open Settings, then tap About Phone at the bottom of the menu. Scroll down and tap Build Number seven times. You will see the same "steps away" messages as on other phones.
Return to the main Settings screen. Tap Advanced, then Developer Options. Toggle off the switch at the top. On newer Samsung models, the toggle may be labeled Developer Mode instead of Developer Options, but the action is the same.
Where to find it on Google Pixel phones
Open Settings and scroll to About Phone. Tap Build Number seven times. The "steps away" counter will appear and count down to zero.
Return to Settings and scroll down. You will now see System as an option — tap it. Inside System, tap Developer Options. Toggle off the switch at the top of the menu. The menu will close and Developer Options will no longer appear in your Settings.
What happens after you turn it off
Once you toggle Developer Mode off, the Developer Options menu disappears from Settings. Any settings you changed inside Developer Options — like USB debugging or animation speed — revert to their defaults. Your phone returns to its normal state.
Nothing on your phone is deleted or lost. Your apps, photos, messages, contacts, and all other data remain exactly as they were. The only change is that those advanced tools are hidden again and no longer accessible unless you repeat the Build Number tap sequence to re-enable Developer Mode.
Why you might want to turn it off
Developer Mode can expose your phone to security risks if you are not careful. USB debugging, for example, lets anyone with a computer connected to your phone install apps or access files without your permission. If you enabled Developer Mode to follow a tutorial or test something and no longer need it, turning it off removes that potential vulnerability.
Some people also turn it off straightforward because they do not use those tools and prefer a cleaner Settings menu. There is no performance penalty to leaving it on — it does not slow your phone down — but disabling it is the safer choice if you are not actively using the features.
Troubleshooting if you cannot find Developer Options
If you tapped Build Number seven times but Developer Options does not appear in Settings, restart your phone and try again. Sometimes Android needs a moment to register the change. After the restart, go back to Settings and scroll down — Developer Options should now be visible.
If you are still not seeing it, double-check that you tapped Build Number (not Android Version or another field) and that you tapped it exactly seven times. The counter should have reached zero. On some phones, Developer Options appears under System or Advanced rather than at the top level of Settings, so scroll through all available submenus.
Frequently Asked Questions
Does turning off Developer Mode delete my apps or data?
No. Turning off Developer Mode only hides the advanced settings menu. All your apps, photos, messages, contacts, and other data stay on your phone exactly as they are. You can turn Developer Mode back on at any time without losing anything.
Can I turn Developer Mode back on if I need it again?
Yes. The process is identical: go to About Phone, tap Build Number seven times, then toggle Developer Options back on in Settings. You can turn it on and off as many times as you want.
Is it dangerous to leave Developer Mode on?
It depends on what settings you have changed inside Developer Options. USB debugging is the main risk — it lets someone with physical access to your phone install software without your permission. If you are not using Developer Mode actively, turning it off removes that risk.
Will turning off Developer Mode slow down my phone?
No. Developer Mode does not affect your phone's speed whether it is on or off. Turning it off straightforward hides the menu and resets any advanced settings you changed back to their defaults.
What if I cannot remember where Build Number is?
It is always in About Phone (or About Device on Samsung). If you cannot find About Phone, open Settings and scroll all the way to the bottom — it is usually the last item in the list. Once you are in About Phone, Build Number is near the bottom of that menu.
