- iPhone (iPhone 8 and later): Press and quickly release the volume up button, then press and quickly release the volume down button, then press and hold the side button (power button) until the Apple logo appears.
- iPhone (iPhone 7/7 Plus): Press and hold the side button (power button) and the volume down button simultaneously until the Apple logo appears.
- iPhone (iPhone 6s and earlier): Press and hold the home button and the side button (power button) simultaneously until the Apple logo appears.
If the phone restarts, great! Back up your data immediately. If not, continue with the following methods.
Connecting via USB Debugging (If Enabled)
If USB debugging was enabled on your phone before the black screen issue, you have a much better chance of accessing your data.
What is USB Debugging?
USB debugging allows your computer to communicate directly with your Android phone at a system level. It’s primarily used for developers to test and debug apps, but it can also be helpful in data recovery situations.
Using ADB (Android Debug Bridge)
ADB is a command-line tool that allows you to communicate with an Android device. Here’s how to use it:
- Download and install ADB on your computer: You can find ADB as part of the Android SDK Platform Tools. Search online for “Android SDK Platform Tools download” and follow the instructions for your operating system.
- Extract the downloaded ZIP file to a folder on your computer.
- Open a command prompt or terminal window in the folder where you extracted the ADB files.
- Connect your phone to your computer using a USB cable.
- Type the following command and press Enter:
adb devices- If your phone is recognized, you’ll see its serial number listed. If not, ensure you have the correct USB drivers installed for your phone model. You can usually find these on the manufacturer’s website.
- Data Recovery: If ADB recognizes your device, you can use various ADB commands to retrieve data. For example, to copy all files from your phone’s internal storage to a folder on your computer, you could use a command like:
adb pull /sdcard/ C:\PhoneBackup(replace “C:\PhoneBackup” with the desired folder on your computer). Note: This command will take a significant amount of time depending on the amount of data. - Attempting a Reboot: You can also try rebooting your phone using the command:
adb reboot
Installing USB Drivers
Your computer needs the correct USB drivers to communicate with your phone. If ADB doesn’t recognize your device, download and install the drivers from your phone manufacturer’s website. Search for “[Your Phone Model] USB drivers” on Google.
Connecting in Recovery Mode
Recovery mode is a separate boot environment that allows you to perform tasks like factory resetting your phone or installing software updates.
Accessing Recovery Mode
The method for entering recovery mode varies depending on your phone model. Common methods include:
- Android (General): Power off the phone. Then, press and hold the power button and volume up button simultaneously until the recovery mode menu appears.
- Samsung: Power off the phone. Then, press and hold the power button, volume up button, and home button (if your phone has one) simultaneously until the recovery mode menu appears. If your phone doesn’t have a home button, try the Bixby button instead.
- Other Android Devices: Search online for “[Your Phone Model] recovery mode” to find the specific instructions for your device.
Using ADB Sideload (If Available)
Some recovery modes offer an “ADB Sideload” option. This allows you to install a ZIP file (like a software update) from your computer. While it might not directly retrieve your data, it could potentially fix a software issue causing the black screen.
- In recovery mode, navigate to the “ADB Sideload” option using the volume buttons and select it with the power button.
- On your computer, open a command prompt or terminal window in the folder where you extracted the ADB files.
- Type the following command and press Enter:
adb sideload [filename.zip](replace “[filename.zip]” with the path to the ZIP file you want to install). You’ll need a compatible ZIP file, like a stock ROM for your phone model. Search online for “[Your Phone Model] stock ROM” to find a suitable file. - Follow the on-screen instructions.
Factory Reset (Last Resort)
A factory reset will erase all data on your phone. This should only be considered as a last resort if you cannot retrieve your data any other way. In recovery mode, navigate to the “Wipe data/factory reset” option using the volume buttons and select it with the power button.
Warning: This will delete all your data.
Using Data Recovery Software
Several data recovery software programs claim to be able to retrieve data from a phone with a black screen. These programs often require root access, which can be difficult to obtain on a phone with a non-responsive screen. Examples include Dr.Fone, Tenorshare UltData for Android, and iMyFone D-Back. Research these options carefully and read reviews before purchasing.
Considerations When Using Data Recovery Software
- Compatibility: Ensure the software is compatible with your phone model and operating system.
- Root Access: Some software requires root access, which can void your phone’s warranty.
- Success Rate: Data recovery is not guaranteed, and the success rate can vary depending on the severity of the damage and the condition of the phone’s storage.
- Cost: Data recovery software can be expensive.

What are the common causes of a phone displaying a black screen?
A black screen on your phone can stem from various issues. Software glitches, such as a crashed operating system or a frozen app, are frequent culprits. Hardware problems, including a damaged screen, a faulty battery, or a malfunctioning internal component, can also lead to a black screen.
Other potential causes include a drained battery (even if the phone was recently plugged in), a corrupted system update, or physical damage from dropping the device. It’s crucial to rule out the obvious, such as a dead battery, before exploring more complex troubleshooting steps.
Is it possible to recover data from a phone with a black screen?
Data recovery from a phone with a black screen can be challenging but is often possible. The feasibility depends largely on the cause of the black screen and whether the phone’s internal storage is still accessible. If the issue is software-related and the phone can still be recognized by your computer, you might be able to use data recovery software to retrieve your files.
However, if the black screen is due to severe hardware damage to the phone’s storage or motherboard, data recovery becomes significantly more difficult and might require professional help from a specialized data recovery service. These services often have advanced equipment and techniques to access data from severely damaged devices.
What is ADB and how can it help with a black screen phone?
ADB, or Android Debug Bridge, is a command-line tool that allows you to communicate with an Android device from your computer. It’s part of the Android SDK (Software Development Kit) and is primarily used by developers for debugging and testing apps. In the context of a black screen phone, ADB can be useful for attempting to diagnose the issue and potentially recover data or perform certain commands.
For instance, you might be able to use ADB commands to reboot the phone, access system logs to identify the cause of the black screen, or even initiate a data backup if the phone is responsive enough. However, using ADB requires some technical knowledge and familiarity with command-line interfaces.
What is the difference between a hard reset and a soft reset, and which is appropriate for a black screen?
A soft reset is simply restarting your phone. It’s the equivalent of turning your phone off and on again. This process typically doesn’t erase any data and can often resolve minor software glitches or temporary freezes. It’s usually the first troubleshooting step for a malfunctioning phone.
A hard reset, also known as a factory reset, restores your phone to its original factory settings, effectively erasing all data, apps, and settings you’ve added. A hard reset is a more drastic measure usually reserved for situations where the phone is severely malfunctioning, and you’ve exhausted other troubleshooting options. For a black screen, attempting a hard reset is only advisable if you’ve backed up your data or are willing to lose it in an attempt to revive the phone.
How can I mirror my phone’s screen to my PC if the screen is black?
Mirroring a black screen phone to your PC is generally impossible using standard screen mirroring apps or methods. Screen mirroring relies on the phone’s display being functional so that the app can capture and transmit the screen contents. If the screen is completely black, there’s nothing to mirror.
However, if the phone is still technically running and responds to touch (even if you can’t see anything), and you previously had debugging enabled and authorized your computer, you *might* be able to use ADB to mirror the screen through a command-line interface, though this is a complex and advanced procedure. Otherwise, screen mirroring is not a viable solution for a completely black screen.
What are some signs that the black screen is caused by a hardware issue rather than a software issue?
Several indicators point towards a hardware problem causing the black screen. If the phone recently experienced physical trauma, such as being dropped or exposed to water, it’s highly likely that the black screen is due to damaged internal components. Similarly, if the phone consistently displays a black screen even after attempting basic troubleshooting steps like charging or a soft reset, it suggests a hardware malfunction.
Other signs include unusual sounds coming from the phone, such as clicking or buzzing noises, or if the phone becomes excessively hot. Intermittent black screens, where the phone occasionally functions normally before reverting to a black screen, can also indicate a failing hardware component, particularly the screen or the battery.
What should I do if none of the troubleshooting steps work and my phone still shows a black screen?
If you’ve exhausted all basic troubleshooting steps, such as charging the phone, performing a soft reset, attempting to connect to a computer, and trying button combinations, and your phone continues to display a black screen, the next step is to seek professional assistance. This typically involves contacting the phone’s manufacturer or visiting a reputable phone repair shop.
A qualified technician can diagnose the underlying issue, whether it’s a hardware problem or a more complex software malfunction. They have specialized tools and expertise to repair or replace damaged components, potentially restoring your phone to working condition. Be sure to back up all your data to the cloud or to an external device before visiting the repair shop, if at all possible.
