The Samsung Galaxy S7 is a powerful and feature-rich smartphone that was once a flagship model for the company. However, like all electronic devices, it’s not immune to issues, and one of the most frustrating problems you can encounter is when it refuses to turn on. This can be due to a variety of reasons, ranging from software glitches to hardware failures. In this article, we will delve into the possible causes and provide you with a step-by-step guide on how to fix your Galaxy S7 if it won’t turn on.
Understanding The Possible Causes
Before we dive into the solutions, it’s essential to understand the potential reasons behind your Galaxy S7’s inability to turn on. Hardware and software issues are the two main categories of problems that could be causing this issue. Hardware problems might include a faulty power button, a damaged charging port, or a malfunctioning battery, among others. On the other hand, software issues could range from a corrupted operating system to a bug that’s preventing the device from booting up properly.
Diagnosing The Issue
To fix the problem, you first need to diagnose the issue. Start by checking the basics:
– Ensure that your device’s battery is not completely drained. Sometimes, a device might not turn on if the battery is too low to even display the low battery warning.
– Check the power button for any signs of physical damage or obstructions. Clean around the power button gently if necessary.
– Verify that the charging port is clean and free of debris. Dirt, dust, or water in the charging port can prevent the device from charging or turning on.
Checking for Signs of Life
If your Galaxy S7 still doesn’t turn on after checking the basics, look for any signs that it might be receiving power:
– Plug your device into a charger. If the charging indicator (a small lightning bolt icon or a charging animation) appears on the screen, it means your device is receiving power but has a software issue preventing it from turning on.
– If the screen remains black but the device feels warm after being plugged in for a while, it suggests that the device is charging but not booting up properly.
Troubleshooting Steps
Now that we’ve covered the possible causes and how to diagnose the issue, let’s proceed with some troubleshooting steps to fix your Galaxy S7.
Forcing A Restart
Sometimes, a simple forced restart can resolve the issue, especially if the problem is software-related. To force restart your Galaxy S7:
– Press and hold the Volume down button and the Power button simultaneously for at least 10 seconds.

Bootling Into Safe Mode
Booting your Galaxy S7 into safe mode can help you determine if a third-party app is causing the issue:
– Press and hold the Power button until your device starts booting up.
– Immediately release the Power button and hold the Volume down button.
– Keep holding the Volume down button until your device boots up completely. You will see “Safe mode” displayed on the bottom left corner of the screen if successful.
Boot Loop And Recovery Mode
If your device is stuck in a boot loop or you need to perform a factory reset, you might need to access the recovery mode:
– Turn off your device. If it won’t turn off normally, wait until the battery drains or remove the SIM card and SD card, then press and hold the Volume up, Home, and Power buttons simultaneously for 10-15 seconds.
– Release the Power button when the device vibrates but continue holding the Volume up and Home buttons.
– Use the Volume down button to navigate to “wipe data/factory reset” and press the Power button to select it.
