This simple yet effective solution resolves many temporary system crashes:

1. 1 Press and hold both the Volume Down and Power buttons simultaneously
2. 2 Continue holding for up to a full minute (particularly important if you see a pulsing blue light)
3. 3 Release when you feel the device vibrate or see signs of restarting

Many users have successfully resolved the issue with this power cycling method:

1. 1 Allow your device to completely drain its battery until powered off
2. 2 Hold the power button to ensure the battery is fully depleted
3. 3 Connect your Samsung to a charger
4. 4 Let it charge to at least 15-20% before attempting to power on
5. 5 Try powering on your device normally

Access your device’s recovery menu to perform additional troubleshooting:

1. 1 Press and hold Volume Up + Home + Power buttons simultaneously for about 15 seconds
2. 2 Look for the “Installing System Update” message on screen
3. 3 Wait for the recovery menu to appear
4. 4 Select “Reboot system now” to restart your device

Clearing the system cache can resolve many system-related issues:

1. 1 Enter recovery mode using Volume Up + Home + Power buttons
2. 2 Use volume buttons to navigate to “Wipe Cache Partition”
3. 3 Press power button to select and confirm
4. 4 After completion, select “Reboot System Now”

1. 1 Let your battery drain completely
2. 2 Press Volume Up + Home + Power Button simultaneously to enter recovery mode
3. 3 Select “Factory reset” using volume buttons to navigate
4. 4 Confirm and wait for the process to complete

If your device was recently dropped or damaged:

• Check if the screen has physical damage (even if not visible to the naked eye)
• If the pulsing blue light stops when receiving notifications and the phone makes sounds/vibrates normally, it’s likely just a screen issue requiring replacement
• If the blue light continues pulsing indefinitely without response, the storage may have failed

For persistent issues, specialized software can help:

1. 1 Download and install Android system repair software on your computer
2. 2 Connect your Samsung device to the computer
3. 3 Select “Repair Android System” option
4. 4 Follow the on-screen instructions to download firmware and repair your device

Consider visiting a professional repair service if:

• None of the above methods work
• You need to recover important data from the device
• There’s visible physical damage to the device
• You suspect hardware failure (constant blue light without any response)

Can I recover data from my Samsung S6 with black screen and blue light?

Data recovery may be possible if the issue is only screen-related. Professional repair services can often extract data even if the screen isn’t functioning. If the storage has failed (indicated by a continuously pulsing blue light that never stops), data recovery becomes much more difficult or impossible.

How can I tell if my Samsung S6 has a screen issue or a more serious problem?

If the pulsing blue light stops when receiving notifications and the phone makes notification sounds or vibrates normally, it’s likely just a screen issue. If the blue light continues pulsing indefinitely without any response to inputs, the problem may be more serious, such as storage failure.

Will replacing the battery fix the Samsung S6 black screen with blue light issue?

Battery replacement might help if the issue is power-related, but it’s not guaranteed. If both the original and replacement batteries don’t resolve the issue, there may be deeper problems within the phone itself.

How long should I hold the button combinations when trying to force restart my Samsung S6?

For force restart attempts, hold the button combinations (such as Volume Down + Power or Volume Up + Home + Power) for at least 15-20 seconds, and up to a full minute if you see a pulsing blue light.
