Or, you may need to transfer chats, text messages, retrieve deleted text messages from your Android phones using third party apps. In such scenarios, the Android operating system does not give permission to do so, unless you turn on the USB Debugging mode.
Here, one important thing to keep in mind, is that, USB debugging is actually used to bridging a connection between the Android device to the Android Software Developer kit using USB connectivity. So, you should not fidget with these settings unless you are particular about your requirements.
Use it to copy your data between your computer and your device, install apps on your device without notification and read log data. Enabling developer mode, or enabling USB debugging leaves your Android device in a vulnerable state.
It provides access to a user to root the device, flash a factory image, use Android debugging bridge ADB and perform functions that involve risk. So, why Android has left the device open to such options? This is because, these are advanced developer options.
People who are Android developers have a strong command over such things and they need these stuffs for their regular operations. To use the USB debugging feature, you have to manually enable the Developer options. But, if you are a normal user who knows nothing about Android development, you might get lost amid such settings and jeopardize your handset in a spree to experiment. So, it is advisable to curb your excitement of using these settings. As mentioned earlier, USB debugging leaves your phone in a vulnerable state.
With USB debugging turned on, if you connect your device to any PC, it will get connected and can even transfer data automatically without even providing any notification for the same. Your child can connect the device to any computer and unintentionally create havoc.

This is way faster than manually sideloading APK files every time. A common reason for non-developers to enable USB debugging is to root their phones. Rooting varies by device and changes over time, but most methods involve some program that you run from your desktop.
Once you enable USB debugging and connect your phone, you can use a tool to send the root instructions to your device without even touching it. Installing a custom ROM involves a similar process. Using these, you can install APK files stored on your PC onto your phone, move files back and forth, and view device logs for debugging errors.
ADB commands and Fastboot can also save your bricked device even when you can't turn it on normally. Most notable was taking a screenshot over USB, which was just as annoying as it sounds. This was before taking a screenshot on Android had a standard command and was easy. Now, you just need to hold your device's button combination usually Power and Volume Down to grab a screenshot, rendering this method obsolete. In theory, with USB Debugging enabled, plugging your phone into a public charging port could open it up to risk.
If someone had access to the port, they could potentially steal information off your device or push malicious apps to it. This is why Android displays a confirmation prompt, so you don't connect to a PC you don't trust. However, an unsuspecting user could accept the prompt without realizing what it's for.
Additionally, leaving USB Debugging enabled makes your device open to attack if you were to lose it. Someone who knew what they were doing could connect your device to their computer and issue commands to it via ADB, without knowing your PIN or other lock screen security. That's scary, and a good reason you should have Android Device Manager set up so you can factory reset your Android device remotely. It's fine to leave on for a few days while you're working on something, but there's no need to have it enabled when you're not regularly using it.
The risks outweigh the benefits in that case. In case you've enabled USB debugging and it's not working, chances are that your USB cable or some configuration option is to blame. See what to do when your Android phone won't connect to your computer to fix your issue. Make sure that you've properly installed and updated the Android SDK on your computer, as well.
This is buried deep in a separate menu so you're unlikely to come across it naturally, but it's still useful to know the differences. This tool allows your phone to read the contents of the screen out loud, helping users with visual disabilities to navigate around their device. It sends information about the contents of your screen to your device's logs. The purpose of this feature is to help developers design their apps for accessibility, and knowing what exactly TalkBack is reporting to users is important for this.
