Why Won't My Galaxy S8 Turn On? How To Fix This Issue

Some readers made reports saying that their Galaxy S8 won't turn on. It is a must to mention here that it is just a minor glitch that can be solved easily in most cases. So, no need to replace the phone. Instead, go through all the possible solutions stated in this article and try implementing each one to see if it solves the issue.

 

Potential Fixes For A Galaxy S8 That Won’t Turn On Or Charge

There are several practical methods to fix this issue, and all of them are listed below.

Solution 1: Hit the power button correctly

While this may sound weird to you, this should be the first step to perform if your Samsung Galaxy S8 won't turn on. If you are pressing the power button improperly, it may cause the device not to turn on. So, to ensure you are not to blame for this issue, try hitting the power button several times and see if the device turns on. If this does not help, move to the second method explained here.

 

Solution 2: Soft reset/Forced reboot

On smartphones equipped with a removable battery, performing a restart or force reboot is very simple and requires the users to pull out the battery, wait for a few seconds then reinsert the battery to turn it back on. 

This, however, does not apply to the Galaxy S8 as it comes packed with a non-removable battery. So, to perform a force reboot or soft reset, press the Volume down and power buttons simultaneously for around 7-10 seconds. 

If there is a minor firmware issue in the device, this process will resolve it, and the Galaxy S8 will typically start. But if the device remains unresponsive, then move to the following method.

Solution 3: Charge your Samsung Galaxy S8

Another reason why your Galaxy S8 won't turn on is because the device is running out of power or no power is left in the device. 

First, put the device to charge for at least five minutes and then check to see if the charging sign is noticed on the screen of your Galaxy S8. Also, remember to use the charger that came packed with the device. Again check to see if the LED light at the top of the display is turning up. 

These two are signs that the device is charging. If these two signs are noticed, then the phone is charging. Let it charge for a few minutes, and then hit the power button to see if your device turns on. If the phone still refuses to turn on, move on to the next method.

Quick Tips

• Try charging your phone with another charger
• Try charging your phone via a computer, wall outlet, a lamp or a wireless charging station. 
• Ensure that the cable is not damaged.
• Remove any phone case, MagSafe or battery-pack accessories.

Solution 4: Boot in safe mode

There might be a culprit app causing this issue, and this can be tested by turning the device into safe mode. To do this, follow the instructions below:

• Ensure your device is Off
• Press and hold the Power and the Volume Down buttons at the same time, to turn the device on. 
• Once the Samsung logo appears on the screen, you can let go of the power button. Ensure you keep holding the Volume Down Button
