If you’re a consumer who has an Android phone, then this blog post is for you. You may have been prompted to turn on developer mode in your settings menu and are not sure what that means or why it’s necessary. This article will explain what developer mode does and how to disable it if you don’t want to use this feature.
What is developer mode?
Developer Mode is a setting that allows developers better access to the device when they need to debug their app or test new features before releasing them publicly. It also enables some administrative functions such as testing apps with rooted devices, running custom scripts during installation of an APK file, debugging system UI crashes without having physical access to the phone, enabling USB tethr and wifi debugging, etc. You can read more about developer mode here .
Why you should disable android developer mode
A few years ago, android developer mode was a very useful feature. However, the past few versions of Android have made it less necessary to access many of the features locked down in this menu. Still, there are some reasons why you may want to disable android developer mode on your device.
What can developer mode be used for?
Developer options are mostly useful for application developers as it allows them to use their devices as a testing bed. However, system hackers may also find these features useful if they want to experiment with adb or install other applications from unknown sources. Other users have been known to use Developer Mode’s USB debugging option for rooting their device but that is not a supported feature and will void your warranty should you send in a device containing a modified Bootloader. In fact, if Sony detects an unlocked bootloader on the Xperia Z3 then it will stop working even with an official update! There are ways around this
If you do not wish to develop Android apps, then it is recommended that you disable this setting. Some users have reported problems with their phones after turning on Developer Mode, even wiping the phone clean or flashing a new ROM doesn’t fix these issues. If your phone is running slow, if your battery doesn’t last as long as it used to, or you’re having some other problems after turning on Developer Mode, then follow these steps to disable this setting:
1. Go to settings
2. Scroll down and click “developer options”
3. Turn off the developer mode switch by sliding it to the left
4. Press back on your phone’s main screen, and you’re done!
5. If you want to turn it back on later, follow steps 1-3 again but slide the switch in the opposite direction (to right)
6. enjoy all of those new features!
These issues do not affect all users and there is no solid explanation for why it happens; however, turning off the developer mode seems to resolve many of these problems with little or no negative effects (the features listed above still work). If you want to use these features and you do not know how to program an app, then consider just leaving Developer Mode enabled on your device.
Benefits of turning off developer mode
Developer mode was introduced with Android 5.0 for use during development of an application. Although the settings are hidden by default, this doesn’t mean that Developer Mode is completely useless on a device that hasn’t been used for software development. There are several benefits to disabling Developer Mode on your phone or tablet, especially if you don’t plan on developing apps or using the USB debugging connection at all:
1) You can hide system files and folders from non-root (i.e., regular user) applications. This means any third party applications will not be able to access these sensitive system files/folders including downloads stored in the download folder (UPDATED). The benefit here is that it reduces your risk of having personal data stolen through apps that gain unauthorized access to these files.
2) You can speed up performance. Once you disable Developer Mode, Android no longer runs unnecessary background services for the purpose of monitoring and updating files in the system folder where your downloaded apps are stored at (/system/app). It also prevents those pesky “Can’t find file” messages from constantly being thrown when trying to download or update third party applications from unknown sources.
3) You can save on battery life as it will cause less wake locks (caused by the aforementioned developer mode related background services). Not everyone who uses their phone on a regular basis is going to have their screen constantly lit up throughout the day on a regular basis, but if you do then it’s a good idea to disable Developer Mode.
4) It prevents other people from knowing that you’re using an Android device since the notification light (if present on your phone or tablet) will no longer blink like crazy every time there’s a new message, email, tweet, etc… 5) If you don’t plan on using it to tinker with your device and just need simple file access then it can be useful for certain apps such as Solid Explorer which only supports root mode otherwise. Keep in mind though that accessing external storage via MTP requires root mode so this benefit is limited.
6) Disable automatic checking for updates: This means if you notice that an update has been made to one of your system applications you will still have to check manually instead of receiving the update notification every time you restart your device.
7) You can prevent your device from broadcasting certain WiFi related information. This includes the name of the network that you’re currently connected to which by itself isn’t all that sensitive, but it also causes your phone/tablet’s bluetooth to try and automatically connect to any paired bluetooth devices in range unless manually disconnected beforehand. If this sounds like something you don’t want happening then simply turn off Developer Mode before connecting to a Bluetooth enabled device or accessing an EAS protected corporate network (i.e., school, work, etc…). Now if for some reason you are not allowed to disable Developer Mode on your Android device due to company policy, there is another option available thanks to XDA member Snoop05 who has recently released an app called Disable Dev Mode for Android 5.0/5.1 Lollipop devices (UPDATED). This software mod can be used to achieve the same results as simply disabling Developer Mode on your phone or tablet, but without having to go into recovery mode which is still restricted by many manufacturers even with the latest updates (i.e., don’t expect to install this if you’re on AT&T and running Marshmallow unless of course you plan on rooting first). It also doesn’t require root access so any standard user can use it provided their device is running Android 5.0 or higher for maximum compatibility no matter when the device was manufactured since support goes all the way back to KitKat.
