It can be stressful when your Samsung phone won't turn on, and you have no idea what went wrong. This problem can happen to any Samsung Galaxy model, but in many cases, it doesn't mean your device is permanently damaged. With the right troubleshooting steps, you can often bring your phone back to life within minutes.
In this guide, we'll walk you through the most effective methods to diagnose why your Samsung phone won't turn on and show you the step-by-step solutions to get it working again. No matter which Samsung Galaxy S series, Note, A series, or Z Fold/Flip model you're using, these troubleshooting tips will help you quickly identify the cause and restore your device.
When your Samsung phone won't turn on, it usually indicates a power-related issue, a software crash, or a hardware malfunction. Below are the most common reasons:
Understanding the cause helps you choose the right solution. Now, let's move to the step-by-step fixes.
Follow these solutions in order (from simplest to advanced) to maximize chances of fixing the issue without professional help:
A faulty charging setup is often the hidden culprit when your Samsung phone won't turn on. Start by inspecting the core components of the charging system to rule out basic issues:
* Charging Port Inspection
Turn off the phone (if accessible) and examine the charging port for lint, dust, or debris - these can block the connection between the cable and port. Use a dry, soft-bristled brush (or a toothpick wrapped in clear tape) to gently clean the port; avoid metal tools as they may bend the internal pins.
* Charger & Cable Check
Look for visible damage on the charger adapter (e.g., burn marks, cracked casing) and USB cable (frayed wires, loose connectors). Try wiggling the cable slightly while plugged in, if the charging indicator flickers, the cable or port may be faulty.
* Power Source Test
Plug the charger into a different wall outlet (not a computer USB port, which delivers less power) to ensure the issue isn't with the power source itself. If you have a wireless charger compatible with your Samsung model, try using it; this can bypass port-related problems.
If the battery is completely drained, your Samsung may need several minutes before showing the charging icon.
Try this:
If the battery is heavily depleted, your phone might vibrate or show the power icon only after some time.
Using an incompatible or low-quality charger may prevent your Samsung phone from charging properly, which can cause it not to turn on. Samsung devices require specific charging standards, so make sure you use the right accessories:
* Use Official Samsung Chargers
The original charger and cable are optimized for your device and ensure stable power delivery.
* Check Third-Party Compatibility
If using a third-party charger, confirm it supports Samsung's charging protocols (Adaptive Fast Charging or Super Fast Charging) and matches the required wattage. Avoid cheap, unbranded chargers.
* Try Another Official Charger
Borrow a certified Samsung charger to test. If your phone charges normally, your original charger may be faulty.
A system glitch or temporary crash can make your Samsung phone unresponsive, giving the impression that it won't turn on. A hard restart forces the device to reboot without erasing your data.
Here's the simplest way:
For most Samsung models:
For very old models with a Home or Bixby button:
Press and hold "Power" + "Volume Down" + "Home/Bixby" for about 10 seconds.
Booting your Samsung Galaxy S25 in Safe Mode allows you to get to the root of the problem because it is able to alleviate the threat of a software crash. If you have successfully booted it in the Safe Mode, you don't need to worry anymore.
The following shows you how to boot your device into Safe Mode:
If your Samsung phone won't turn on due to system crashes, firmware corruption, or black screen issues, using a professional Android repair tool can be an effective solution.
