Options for developers are nothing new. They allow tech-savvy users to get even more out of their devices. As the name implies, these are options available to developers to test their apps. As you’d expect, they’re hidden deep inside your phone so ordinary users can’t accidentally configure things they’re not sure about.
Most of the settings for developers are not in plain English, but if you know what you’re doing, they can help you customize your Galaxy S10, S10 and S10e. By enabling developer options, Galaxy S10 users can access features such as GPS swapping and faster animations. They can also allow users to keep their device’s screen on at all times, even while charging, and adjust the animation or DPI to match the size of the screen content.
If you enable developer options on the Galaxy S10, it won’t invalidate or cause any problems with your device’s warranty, because the developer menu is built into the phone. However, using it unknowingly can negatively affect the performance of your device. This is the main reason why smartphone manufacturers hide it from most users.

What is developer mode in Android and why you need it?
There’s an interesting “For Developers” item in the settings of your device. It allows users to configure the system’s behavior, activate some functions, and developers to debug the desired application/game. For example, in this tutorial we will explain how to enable “USB Debug Mode” (see point 4 in the description of the developer menu functions), where the error report is viewed, the factory unlocking of the boot loader is enabled and much more.
Despite the fact that all Android devices have the same settings for developers, device manufacturers may have this option in different sub-items of the Settings menu. Now we’ll break down exactly how and where to enable/disable developer mode on your Android smartphone or tablet, and then we’ll tell you what features and under what circumstances you can use.
How to enable developer mode on Android:
For most Android devices, including Xiaomi: Go to “Settings”. “About phone. Looking for “Build Number”
For Samsung: Go to “Settings”. “About”. Looking for the “Build Number” item
For HTC: Go to “Settings”. “About.”. “Software Information”. “Advanced.”. Look for the “Build Number” item
When you get to “Build Number” with a set of different symbols, you should click on this item 7 times. After performing this action, a pop-up message will appear informing you that “Developer settings are enabled”.
Go back to the main settings menu and find the “For Developers” section.
For clarity, we have attached a video instruction that shows the process of activating the “For Developers” menu.
If you are not able to activate the developer mode on your Android device, try tapping “everything” under About, in rare cases there may be no notifications, so just scroll through the menu, you will very likely find that the developer mode is activated. Otherwise. specify your device model and firmware/ build version in the Комментарии и мнения владельцев and we will help you.
How to activate the “For Developers” item on Android 8 and 9
On Android 8.0 and newer, to enable the developers menu, go to “System” (the last settings menu item). In this section, find the “About the phone” sub-item (also at the very bottom).
By clicking on the “Build number” line 7 times, you will get a notification that you have become a developer.
The “For developers” item will appear in the “System” section of the main settings menu.
Developer mode in MIUI on Xiaomi
In the MIUI firmware on Xiaomi, the menu for developers is activated in a similar way. The item “About phone” is the first in the settings menu. Go there and look for the “MIUI version” option. Quickly tap on it 7 times in a row and the “You have become a developer” notification will appear!”.

After activation of the mode, go to the main settings menu and find “Advanced settings” item (in the “System and device” group). The Developers menu is at the end of the list; it is the third item from the bottom.
How to remove or disable Developer Mode from the Preferences Menu:
It is worth noting that some of the devices do not allow to rotate this operation, but in most cases the item is hidden in one click. Go to the Settings menu, scroll to “For Developers,” enter it, and uncheck the box next to the word “Enabled. The device will automatically return to the previous section and the item “For developers” will disappear.
If for some reason you don’t find the “Enabled” checkbox, you should use the following instructions:
Open “Settings”. “Applications”. “Settings”. Then go to “Storage” and select “Erase data, Clear Cache”. This method is suitable for most smartphones and tablets, so if it helped you, be sure to report it in the Комментарии и мнения владельцев of the article.
Useful functions and options in the menu “For Developers”, which can be useful in some situations.
Don’t turn off the screen. If this option is activated, the screen of your device will never turn off if the charger is connected. This trick will be useful for Android app developers who have to monitor their brainchild for a long time.
You may also need the function for social networks, where there are “live” updates and you do not have time, desire, to constantly press the screen, so that the screen does not turn off. It’s worth being careful for owners of devices with AMOLED displays, as you may experience what’s called a “burn effect” on your screen. the image is imprinted on the display and you can not remove it.
Factory unlock. Unlocking bootloader on your smartphone/tablet allows you to use the custom recovers and other stuff. For example, on a device with locked bootloader there is no possibility to enter Android Repair menu and restore the system to its initial state/install the new OS.
Actually this option doesn’t unlock bootloader, but it gives you “permission” to do so on your device. If you do not plan to perform the above-mentioned manipulations, you should not activate this function.
Running apps. Everyone knows that Windows has a task manager, which shows what processes are running at the moment. This allows you to understand what is working at a particular moment and why the computer is not stable, which consumes most of the resources. You will not find such a feature in the default settings of Android devices, so the function “Running applications” can be very useful.
You will be able to see which applications are running in the background, for how long, and the amount of RAM they consume. You should not try to stop running processes by force, this can lead to unexpected consequences. You do not need to worry, Android has long learned to manage the RAM and its shortage is very rarely felt by users.
USB Debugging Mode. One of few functions that developers need first of all. The main purpose of USB debugging mode is to execute specific actions on your device via commands sent from a PC. For example, by connecting to the Adnroid SDK users will be able to install an application via computer, get the necessary information and even gain ROOT access.
How to enable USB Debugging on Android
To enable the USB debugging mode on your Android device, go to “For Developers” menu, find “USB Debugging” or “USB Debugging” item and enable it!
Of course, no one cancels the usefulness of this parameter, but it is also worth to turn off the USB debugging mode when you are not using it.
Fake location. It is no secret that Android phones and tablets can track by knowing your current location. But few people probably know that Android has a feature that allows you to tell services, apps the fake location of your device. In other words, you need to activate the function and then choose a program for which your device will display the wrong location.
Disable Absolute Level. If you search, you can come across a lot of questions on the web about changing the volume of Bluetooth speakers, headsets, and other devices using your Android smartphone. For unknown reasons it does not always work, the sound becomes louder and then becomes weaker. If you faced a similar problem and would like to get rid of it, then don’t forget to activate the “Disable Absolute Level. Otherwise you should not touch this parameter to continue the normal functioning of the device.
Visual response. When you activate this function, you will see small dots on the screen, allowing you to know exactly where you have pressed. Useful in several cases: for developers, for people who have problems with point movements, and at the moment of recording video from the device screen for better visibility.
In this article we tried to explain what “Developer Mode” is, how to enable, disable it and what useful features you can use without fear of damaging your smartphone/tablet. Of course, there are many other options in the developer settings, but most of them are of no practical value for ordinary users, but are intended primarily for people engaged in software development.
How to enable developer mode on Samsung
Developer mode is a separate menu in the settings of your mobile device that allows you to manage some hidden features of your smartphone. For the sake of security, by default this menu is hidden from the eyes of a common user, but if you want it can be easily activated. How to enable Samsung Developer Mode?
Open the settings of your smartphone and in the section about the phone click on the software information.
Now, quickly click on Firmware Version until it says Developer Mode is enabled at the bottom of the screen.
All that remains is to go back to the initial settings screen and at the bottom of the screen to the Developer Settings section.
The most popular item in the developers menu for most users is Debugging via USB, which is used to unlock, reflash the mobile device, as well as to install third-party software on it directly from a personal computer.
After activating this mode, a new section called “For Developers” appears in the Android settings menu. It opens up new possibilities for the user. Let’s look at some of them, which can be useful even for a simple user:
- Log buffer size. provides the ability to select the amount of clipboard memory;
- GPU acceleration. activates the processing of two-dimensional graphics;
- Show CPU load. displays a screen with information about the current CPU load;
- USB connection. selects the mode of the device when it is connected to the PC via USB;
- USB debugging. enables debug mode when you connect your Android to a PC with a cable.
- Fictitious device location. allows you to make apps “think” that you are in another part of the world.
How to enable Android developer mode
Turning on the developer mode on phones and tablets with Android 6, 7 and earlier versions is the same.
Necessary steps for the “For developers” item to appear in the menu
- Go to settings and at the bottom of the list, open “About phone” or “About tablet”.
- At the end of the list with data about your device find the item “Reset number” (for some phones, such as MEIZU. “MIUI version”).
- Start repeatedly tapping on this item. During this (but not from the first taps) you’ll get notifications that you’re on the right track to enable developer mode (different notifications on different versions of android).
- At the end of the process you will see the message “You are now a developer!”This means that the Android developer mode has been successfully enabled.
Now to enter developer mode settings you can open “Settings”. “For Developers” or “Settings”. “Advanced”. “For Developers” (on Meizu, ZTE and some others). You may need to additionally set the switch of the developer mode to “On”.
Theoretically, on some models of devices with a heavily modified operating system, the method may not work, but I have not seen this yet (it worked successfully with modified settings interfaces on some Chinese phones).
