What to do if a Samsung Galaxy S7 does not turn on symptoms and possible causes

Apart from the obvious black screen and no response to commands, there are other symptoms you may encounter when your new phone has this specific problem:

  • The LED indicator is on but the screen is black and does not respond
  • The screen is black, the LED indicator does not light up or even the phone, even though the power button is pressed
  • You can hear notification sounds but the screen is still black
  • The device turns itself off and refuses to be re-ignited

This problem is common to all smartphones. In fact, we have received hundreds of reports from our readers where they have explicitly stated that they have encountered this type of problem using previous Galaxy models.

What to do if a Samsung Galaxy S7 does not turn on: the most common causes

  • Completely empty battery that takes a few minutes to show life when the phone is connected to the charger
  • The Android system has crashed abnormally leaving the phone in this condition, does not respond when the power button is pressed and even if the charger is connected
  • Some downloaded apps continue to crash and also cause the system to crash
  • The power button remained locked or damaged after the phone fell on a hard surface

What to do if a Samsung Galaxy S7 does not turn on

Most often, these types of problems are caused by system crashes. When this happens, the device does not respond either by pressing the power button or connecting it to the charger. This is because firmware plays an important role in starting up the hardware and charging the battery. Therefore, here’s what you need to do in case this problem occurs …

First step: force the restart of the Galaxy S7

Holding down the “Volume Down” and “On” keys simultaneously for 10 seconds, the phone will disconnect the simulated battery. It’s like when you take the battery out of your phone to restore it.

This procedure is wired, so it should safely work. Once again, just press the “Volume Down” and “On” keys simultaneously for 10 seconds. In addition, the forced restart procedure will update the phone’s memory, so any firmware and/or hardware errors that occurred will be resolved immediately.

What happens if the forced restart procedure failed?

Second step: connect the Galaxy S7 to a charging source

Perhaps the reason why the phone is turned off and not turned on again is because the battery has run out. It could also be the reason why the forced restart procedure failed. So, it’s time to plug in the charger and let the device charge for at least 5 minutes before turning it on.

After 5 minutes of charging, try turning on the phone and if it does not work, try the first step again.

Third step: check if the Galaxy S7 can be started in recovery mode

Now, this procedure will tell us if it’s just a firmware problem or a serious hardware problem. In recovery mode, the Android GUI will not load during startup but all the essential components will be started. So, if the phone boots into recovery mode, it means the problem is with the firmware. Otherwise, it’s a hardware problem.

  • Press the “Home” and “Volume up” buttons at the same time, then press and hold the power button.
  • When “Samsung Galaxy S7” is displayed on the screen, release the power button, but continue to hold down the “Home” and “Volume up” keys.
  • When the Android logo is displayed, you can release both keys and wait for 30 to 60 seconds.

If your phone can boot properly in recovery mode, proceed with clearing the cache partition using the volume keys and the power button to select the option, then try to boot normally. However, if the recovery process failed, proceed with the last step.

What happens if the phone has refused to start normally after the recovery mode?

What to do if a Samsung Galaxy S7 does not turn on to start the Galaxy S7 in safe mode

The problem may have been caused by a third-party app that may have crashed abnormally considering that there are still apps with compatibility issues in the Play Store. In this case, you need to start the phone safe mode only to see if this is possible and to exclude the possibility that it is a hardware problem once and for all.

  • Press and hold the power button.
  • As soon as you see “Samsung Galaxy S7” on the screen, release the power button and hold down the “Volume Down” key.
  • Continue to hold down the “Volume Down” button until the device finishes rebooting.
  • You can release it when you see “Safe Mode” in the lower left corner of the screen.

If your phone was successfully started in safe mode, try uninstalling suspicious apps. Alternatively, you can restore factory settings via “Settings” or “General reset” by restarting the phone in recovery mode.

In any case, the problem will be solved. However, if the boot in safe mode did not succeed, the last option is just the last step: ask the technician to fix the problem or replace the phone

At this point, you have done everything possible to try to solve the problem without compromising the security of the phone and voiding the warranty. It’s time to go to the store where you bought it and let the technician check it.
