Part 3: How to Fix a Samsung Galaxy S3 that won't Turn On

We should mention that this problem is fairly common but there is no single solution to the problem. Even Samsung engineers had to perform some troubleshooting procedures just to figure out what was happening.

There are however a number of troubleshooting procedures you can try on your own. Who knows, you may fix the problem on just the first try. Here's what you can do:

Step 1: Press the power button repeatedly. This is an easy way to determine whether there is indeed a problem with the device.

Step 2: If your device won't turn on no matter how many times you press the power button, remove the battery and then hold the power button down. This is to drain any electricity stored in the components on the phone. Place the battery back in the device and then try powering it on.

Step 3: If the phone stays dead, try booting it in Safe mode. This is to rule out the possibility of an app preventing the phone from booting up. To boot in Safe Mode, follow these steps;

Press and hold the Power button The Samsung Galaxy S3 screen will appear. Release the power button and hold the Volume Down Key

Step 4: If you cannot boot to safe mode boot to recovery mode and then wipe the cache partition. This is the last resort and there is no guarantee that it will fix your device but here's how to do it.

Press and Hold the Volume Up, Home and Power Buttons

Release the Power Button as soon as you feel the phone vibrate but keep holding the other two until the Android System Recover screen appears.

Using the Volume Down button select "wipe cache partition" and then press the Power button to select it. The device will boot automatically.

Step 5: If none of this works you may have a battery problem. If you change the battery and the problem still persists, seek help from a technician. They will be able to determine whether the problem is your power switch and fix it.

Part 4: Tips to Protect your Galaxy S3

If you manage to fix the problem, you will really want to avoid a similar situation in the near future. For this reason, we have come up with a few ways you can protect your device from future problems.

Ensure the apps you download are not corrupt. Some apps may prevent your device from rebooting normally.
Keep your device in a protective case to prevent damage to the power button in case of a fall
Keep your device out of reach of children who may poke and prod eventually damaging the device without your knowledge.
Uninstall any third-party apps that you may think could be causing problems
Regularly clear the system cache on your device. It can magically improve your device's performance not to mention avoid future problems.
Check your device from time to time to ensure it is working correctly.
