How to fix Samsung Galaxy Note 4 that won’t turn on [Troubleshooting Guide]

Your Samsung Galaxy Note 4 is one of the most powerful and most elegant pieces of technology available in the market today but it becomes totally useless if it won’t turn on or power up. Electricity is literally the lifeline of every electronic device and if the accessory that holds that power isn’t functioning the way it should, then you just wasted several hundred dollars.

Galaxy-Note-4-Wont-Turn-On

In this post, I will guide you through troubleshooting a Galaxy Note 4 that won’t turn on. The purpose of troubleshooting is to find out what the problem really is and develop a strategy how to fix it once discovered. Considering the fact we’re dealing with an expensive device, we will take the safest route to troubleshoot it. It means that we won’t guide you through doing something risky that might even make things worse than they are now.

The troubleshooting procedure I use in this post is the guide that we technicians follow to make sure the problem won’t get worse in case we need intervention from the manufacturer’s engineers. Just remember, this post doesn’t guarantee your problem will be fixed but give you an idea what the real issue is so that you can explain to a tech what happens. Information is needed for issues to be fixed especially hardware-related problems.

If, however, you have other concerns with your phone, visit our Galaxy Note 4 Troubleshooting page as it contains a lot of problems we already addressed before. Try the solutions we provided first and if they didn’t work for you, then email us at [email protected]. This service is for free so you won’t be charged. However, we ask you to provide all necessary details about your problem and your phone so we know where to start our search for solution.

So now, let’s proceed to troubleshoot your Galaxy Note 4 that won’t turn on. Here are the steps…

  1. Perform the soft reset
  2. Plug the phone to charge
  3. Plug the phone to a computer (optional)
  4. Try a different USB cable
  5. Try booting the phone in safe mode
  6. Boot the phone in recovery mode

Step 1: Perform the soft reset

This procedure is effective for minor firmware- and hardware-related glitches and it’s safe. None of your data will be deleted if you did this. The procedure is actually very basic as it is mainly a reboot with a twist. Here’s how you do it…

  1. Remove the battery from your Galaxy Note 4.
  2. Press and hold the Power key for a minute once the battery is out.
  3. Place the battery back in once the time elapsed.
  4. Attempt to turn the phone on.

Again, if the problem was caused by a minor firmware or hardware glitch, the device should power up now. Otherwise, there’s something more serious going on with your phone.

The soft reset actually just drains stored electricity from components especially capacitors and that refreshes the phone’s memory. But as I said earlier, it’s safe and none of your data will be touched.

Step 2: Plug the phone to charge

Before proceeding, let us rule out the possibility that it’s just a drained battery problem by plugging the phone in to charge. Of course, use the original charger and USB cable when charging the phone normally.

This procedure can actually tell right on if there’s a problem with the device’s hardware. If the usual charging indicators like the LED or the charging icon on the screen won’t show up, then we can almost assume it’s a hardware issue. If they show up, then there’s still hope you can fix this problem without visiting a tech.

Whether those charging signs show or not, let the phone charge for at least 10 minutes and then attempt to turn the phone on. If it still refused to power back up, then proceed to the next step.

Step 3: Plug the phone to a computer (optional)

This procedure is optional because you only do this if the phone refused to charge or didn’t display the usual charging signs when you plugged it in to the wall outlet. It rules out the possibility that there’s a problem with the outlet preventing the phone to charge.

While computers don’t give out as much current as the charger, it would still be enough to make the phone respond. If it didn’t, then proceed to the next step.

Step 4: Try a different USB cable

Assuming you tried charging the phone through the outlet and computer and it refused to charge, it’s time you rule out the possibility that it’s a damaged USB cable that’s preventing the charge and that the problem might be just a drained battery issue.

Try a different USB cable to know if the device is still capable of charging because if not, then at this point in time, you should already consider having the phone checked by a technician.

Step 5: Try booting the phone in safe mode

Remember, the main issue here is that the phone won’t turn on. It means it won’t respond if you pressed the Power key; the screen won’t light up and the device remains dead and unusable. So, our main focus here is to bring the phone back to life.

Assuming some of the apps you downloaded caused the problem, booting in safe mode will actually make the phone respond. So try this procedure to find out if the phone could power up.

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  4. Safe mode will be displayed at the lower left corner; you may release the Volume Down key now.

If the phone still refused to power on, then, proceed to the last step.

Final Step: Boot the phone in recovery mode

This procedure will attempt to boot the phone up to its barebones. It means that the device will be booted up without loading the usual Android GUI. This is the final step so if it failed, then there’s nothing much you can do about the device but to let the technician sort things out for you.

You don’t need to do anything if the phone booted up in recovery mode successfully. All we wanted to know if it still capable of powering all its components up. Here’s how you boot in recovery…

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.

At this point, you’ve done all the basic troubleshooting procedures. If your phone powered back up, then that’s good news. Otherwise, send the phone in for repair.

How to fix Galaxy Note 4 blank display, screen flickering, unresponsive touchscreen

Among the most common screen-related issues Galaxy Note 4 owners experienced are the blank or black display, screen flickering issues and unresponsive touchscreen. Of course, these problems have a few variations and causes. We received emails from our readers describing relating to the aforementioned issues. In fact, I cited a few below and included instructions how to troubleshoot or work around them.

For Galaxy Note 4 owners, who may be facing different issues, visit our Note 4 troubleshooting page as we indexed all problems we already published before. It is more likely we have already provided solutions to your problems. However, if those solutions don’t work for you, feel free to email us at [email protected] and we will help you fix your problems.

The following are the display-related problems from our readers. Click on the link to go to a specific section:

  1. Galaxy Note 4 display remains black or blank
  2. Galaxy Note 4 display flickers after being dropped
  3. Galaxy Note 4 display jumps between apps & flickers
  4. Galaxy Note 4 touchscreen isn’t functioning

Galaxy Note 4 display remains black or blank

Problem: I badly need your help droid guy! My Galaxy Note 4 was left charging last night but when I woke up this morning, the display won’t light up. I thought it turned itself off so I tried turning it on but it didn’t respond. I already spent more than an hour trying to do things I haven’t done before with it (and most of them I don’t really understand) to no avail.

To give you a better idea, the screen remains blank or black and the phone just won’t light up. I tried plugging it in to charge and it was showing the green light; meaning the battery is full. I’m confused but more than that, I don’t know what happened to it let alone fix this problem. I need your expertise on this. Thanks. — Jessa

Troubleshooting: Hello Jessa. There’s a glimmer of hope for you because, at least, your Note 4 still lights up the LED indicator when plugged it. That’s one sign that it may just be a minor glitch with the system.

Actually, I’ve encountered a lot of issues like this before and it’s not just the Note 4 that’s doing this, it’s common across all Android devices. The most effective troubleshooting procedure to address this problem is the soft-reset.

  1. Open the back panel of your phone.
  2. Remove the battery.
  3. While the battery is out, press and hold the Power key for a minute.
  4. Place the battery back in and then the back panel.
  5. Now turn your phone on.

Just in case the phone won’t turn on after the soft reset, try booting it to different modes such as Safe mode and Recovery mode just to find out if it’s still capable of powering itself up. If not, then there’s nothing much we can do about a phone that won’t turn on. Let a technician take a look at it.

Galaxy Note 4 display flickers after being dropped

Problem: Okay, so I was careless one sweet day and I dropped my Galaxy Note 4 on a tiled floor. The back cover was removed and I thought the battery almost came off and the phone was turned off, of course. I thought it was totally damaged already but when I attempted to turn it back on, it did! I was never happier to see my phone back to life again after it slipped my hand and hit the hard bottom but after a couple of minutes, the screen started to flicker and then the flickering disappeared and after a few minutes, it flickered again and again and such is the cycle. I understand the drop may have messed up everything for me but is there anything I can do to fix this? — Jeffrey

Related Problem: Hello! So, last night I looked at my phone to check the time and I noticed there was a message on my phone stating that my phone was overheating and that all the apps would not be able to be used at that moment (mind you, I was at work so my phone was not being used much at all – I checked a few texts and was tracking a delivery package, that’s about it). I have never seen that message so I decided to just turn my phone off to give it time to cool down. Immediately when I did that, my phone started flickering at the top part of my screen with a line going straight through it (kinda like old school tvs, when you would turn them on and off and you could see the power stripe through the tv)

I let my battery completely drain over the course of the rest of the night. When I thought that it was dead I was going to plug it in but first I tried turning it on. and it worked completely fine for a millisecond before it actually died (I turned it on and there was 1% battery remaining). So, I left it to charge. At 85% battery I turned my phone back on and immediately the screen went black and the flickering began again. On occasion I can turn my phone on but the welcome screen is extremely overexposed and it just shuts off again.

This phone is relatively new, only about 3 months old. No water damage. Minimal dropping but it is protected by a case. I currently am running on Lollipop.

Help!! I don’t know what happened! Thanks in advance! — Kathy

Suggestion: Apparently, the impact of the drop messed up the hardware in your device especially the display. There is a possibility that the drop just loosened some connections inside that’s why the screen flickers. The bad news is, there’s nothing we can do about hardware issues. So, I suggest you bring it to a shop and let a technician check it for you. Or, if you are confident enough to open your phone, then proceed at your own risk and check if it’s just a loose connection or the display was damaged.

Galaxy Note 4 display jumps between apps & flickers

Problem: Hi, my daughter was nice enough to drop my Note 4 (in an otterbox) into a bathtub full of water. I got it out, turned off and wiped down very quickly and put it into a bag of rice over night to dry out (with the back, battery, and stylus out). When I tested it out in the morning, the screen flashes between the “active apps” screen and the “select a home page” screen so fast that I can’t actually do anything. I have factory reset it and have pulled it all apart to help it dry out farther but it isn’t helping. — Amanda

Suggestion: Hello Amanda. When it comes to water damage, we really can’t tell as to what extent the damage is or what functions are affected. In your case, however, it seems like the touchscreen and/or the display suffered so much. Again, we don’t know if its current behavior is caused by liquid that may still be present in your phone or it’s the circuit board that was affected. There’s one way to find out, though. Have it checked by a technician so that proper diagnosis will be done. Then you can decide if you will spend money having the phone fixed or just buy a new one.

Galaxy Note 4 touchscreen isn’t functioning

Problem: My Galaxy Note 4 became so hot yesterday that it shut itself off automatically. After it cooled down, I turned it back on and the screen won’t respond to my touches anymore no matter what I do. So, I am interested to know what caused the overheating and if it can still be fixed. — Leonie

Troubleshooting: Hello Leonie. The problem is, we really don’t know what caused the overheating and you haven’t provided all necessary details. But based on your description, it seems to me like it’s a liquid damage that may have caused the overheating and probably affected some chips inside. The best thing for you to do is have a tech take a look at it as it sounds more like a hardware issue.
