Problem 1: Galaxy Note 4 can’t read 512GB SD card

Can a Samsung Note 4 use a 512GB SD card? I have been trying to transfer several hundred MP3 files to a 512GB SD card. When I format the card with Windows 7 and transfer the MP3 files to it, the computer reads them just fine. When I mount the SD card in the Samsung Galaxy Note 4, it does not show the files and announces that the card needs to be formatted. It does not give me any choices regarding type of format. I suspect the Windows 7 format will work with the Android phone. Is the correct? Can a Samsung Galaxy Note 4 android phone address a 512 gb SD card? — Phillip

Solution: Hi Phillip. A Galaxy Note 4 can only work with a microSD of up to 256GB. Even a Galaxy S8, the latest Samsung flagship, can only read a 256SD card so you’re out of luck. You can keep the card though for more advanced devices in the near future.

Problem 2: Galaxy Note 4 keeps rebooting, volume increases on its own

My phone just one day it wanted to keep turning itself down. And my Bluetooth decided it didn’t want to work either. I have a bluetooth device in my car, and doesn’t work. I tried putting my phone in safe mode, but the problem still occurs. I cannot seem to figure out the problem. I could be using my phone with all volume systems turned all the way up, and then no sound, then it will gradually turn back up.. please send help. It does it while using Spotify and Facebook. — Destiny.n.osborne

Solution: Hi Destiny.n.osborne. The most that you can do when it comes to your issues is to factory reset your Note 4. There may be an app or operating system bug that cause the said problems. If you haven’t tried doing it before, here are the steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off the Galaxy Note 4 completely.
  3. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  4. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  5. When the Android System Recovery shows on the screen, release the Vol Up key.
  6. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  7. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  8. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  9. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.
  10. Check how Bluetooth and volume work afterwards. Make sure not to install any app during this time. If both problems stay, it’s time to send the phone in for repair or replacement.

Problem 3: Galaxy Note 4 becomes very slow, keeps getting TouchWiz has stopped responding error

This morning phone was slow to respond. Finally got message that TouchWiz stopped responding. Phone spontaneously rebooted a few times but would not wake up after lockscreen engaged and display turned off UNLESS I connected it to the car charger. I intentionally powered off. Powered up. It powered itself back off. I found directions for soft reset. Removed battery, held power button for a minute. rebooted. It went through an obvious reset cycle and came to a no-frills black screen with options, including reboot. Chose that using power button. All seemed well until it shut itself off. Now what? I’m unsure of the Android version – it should be on whatever the latest and greatest AT& T has rolled out to me. — Amelia

Solution: Hi Amelia. The first troubleshooting step that you need to do is to clear the cache partition. This is to force the phone to delete the current system cache and replace it with a new one. A corrupted cache can sometimes cause issues so it’s good if you can eliminate it from your list of possible causes. Here’s how to do that:

  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.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

If clearing the cache partition won’t fix the problem, then your next move is to wipe the phone clean with factory reset. Steps are provided above.

There were a few cases in the past where some users were able to fix a problem similar to yours by installing a third party app to minimize wake locks. If the problem remains even after a factory reset, try to use Wake Lock by Darken from Google Play Store.

Problem 4: Galaxy Note 4 won’t boot past Odin mode, stuck in Download mode

Phone keep saying downloading do not remove from target and it also says no command at times. What do I do to fix my phone? I tried factory reset, but when I apply it nothing happens, but the phone turn off completely and I have to take the battery out to restart it every time. and when it do come up the Android guy be on its back and come up to system recovery at times. and I press reboot system, but things are still there same. — Pgrisby36

Solution: Hi Pgrisby36. If nothing happens when you attempt a factory reset, you should try to flash the bootloader. This is a logical next step since your phone appears to boot only to Odin or Download mode. Flashing requires a few things including a computer and an Odin program for the PC. Make sure that you do more research on how to do it. Below are the sample steps on how to flash a bootloader. Exact steps may vary so find a good guide for instructions. The steps below are for demonstration purposes only:

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 5: Galaxy Note 4 has no sound, Youtube won’t play

Hello. I have a SFR Samsung Note 4. It has been causing problems since last year, and I tried everything — reset to factory, the hard reset, bought a new battery, nothing works. Same issue. No sound, don’t know why. Youtube is not loading at all. if you browse the internet, it works to an extent then it freezes and goes black. You can’t make phone calls, it delays in calling, or if I get an incoming call, the screen appears with almost 2 min delay, and once it appears it won’t let me take the call, like literally swipe the green call sign. What else can I do?

I don’t know how to use Odin and install a new operating system on it, but I think this won’t do the job either. Once I had a hard reset of it, it asked for an update, but without or with the update version, still same issues. Can you help me? — Wlf.david

Solution: Hi Wlf.david. Your phone appears to have a general software or hardware issue. We don’t know anything about your device or its history so there’s nothing much that we tell you. Please refer to our suggestions for Amelia above. If nothing will change after doing all of them (cache partition wipe, factory reset, and installation of Wake Lock app), it’s probably high time to replace the device.

Problem 6: Galaxy Note 4 shuts down when taking a picture, overheats when using flash light app, battery doesn’t charge to 100%

Hey there. I’m all the way from Guyana South America and I’m having a few problems with my phone, Note 4. I bought it second hand “refurbished.” The problems are listed below:


  • The phone doesn’t charge to 100% unless I clear the cache, it usually charges to around 50-70%. Also, I do use an original Samsung fast charger
  • Whenever I use the camera, sometimes to take one or a few pictures the phone shuts down. Also when I play real moto it shuts down.
  • If the phone battery reaches around 15% it shuts down and when I put it to charge it show 0%
  • when I use a flash light it gets extremely hot. I have already replaced the battery, wiped cache partition several times and did one factory reset. I have downloaded a few other apps including CM security which I don’t really trust. — Abdel


Solution: Hi Abdel. The only software troubleshooting that we will suggest for you is battery recalibration. If that won’t fix the issue either, there must be a deeper issue with the hardware that causes all these problems. All four issues appear related and can have a single cause. If a battery recalibration can’t fix it, you must have the phone repaired or replaced.

Here are the steps on how to recalibrate the battery:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Problem 7: Galaxy Note 4 keeps restarting on its own

I have the Samsung Galaxy Note 4 and I’ve gone the few 4 replacements going on the 5th after only having it 2 days with the same problems with all of them. It’s driving me crazy. My phone turns on and off on a daily basis even with a full battery. It will not completely turn on at times. I have tried to reset it multiple times and have taken out the battery to try to get it turn back on. I have also bought a brand new battery and it didn’t help the problem. Any idea how I can fix this problem? I have also updated the phone when they become available. — Munozcbn_1983

Solution: Hi Munozcbn_1983. It’s very unlikely that the same exact problem can occur on at least 4 phones unless you yourself is causing it. The main reason may be due to a bad app that you install after setting up your phone. To check, try to boot the phone to safe mode and observe. Safe mode blocks third party apps and services so if the issue won’t occur while safe mode is enabled, that’s a confirmation of our hunch. Here are the steps on how to restart the phone to safe mode:

  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 Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.
  5. Observe the phone for at least 24 hours.

You can also try to factory reset your device and observe how it works when there are no third party apps installed. Like in safe mode, you must observe the phone for a minimum of 24 hours to see a difference. If the issue is absent, uninstall apps one by one until you identify the culprit.

Problem 8: Galaxy Note 4 keeps restarting after Android 6 update

Hello. I had received an Android 6.0.1 update after which phone started restarting abruptly. Contacted Samsung service center who concluded that motherboard is faulty. But when i asked them to explain how can an update destroy the hardware, they had the only answer that, if they can’t re-flash the Android then it should be concluded as motherboard issue, as they are trained to tell that.

I took the phone back and did a research on Google and found that this problem is profound everywhere in the world and one gentleman had suggested a solution for this. The solution from him was to install an app called as Wakelock and set it to some mode. To my surprise, that worked 100% and phone was back to normal when operating in active condition. But if i try to restart it, the app would be inactive thus until i struggle and switch on the phone and reset the app to the above said mode, the phone doesn’t work properly.

Meanwhile, when i spoke to Samsung customer care, they said that they have released a new update, which solves this issue. So i waited for the update and finally i got this new update and i tried to install it. As soon as i gave install, phone went into boot mode and then it never recovered after that. the phone is dead now. Completely dead. tried all the basic steps, like soft start, safe mode, recovery mode. nothing is working. checked the battery voltage using a Multimeter and its delivering the required voltage. Please solve my problem. — Sharath

Solution: Hi Sharath. Installing a third party app like Wake Lock to fix a certain issue is  never a permanent solution. Unless the main cause of the problem is addressed, you can expect that it will return.

We know nothing much about your phone’s history including the possible reasons that may have led as to why your Note 4 now fails to power back on so it can really be anything at this point. We know that there are a lot of Note 4 users that find their device working fine after installing Android’s latest update, we always expect to receive reports of problematic cases simply because Note 4’s hardware was designed to work with older Android versions. Installing the latest Android iteration to it can put a strain on the hardware, leading to all sorts of problems. There’s never any official Samsung explanation why there a lot of Note 4 devices failing after an update but the general rule, if a broken device can’t be fixed by software troubleshooting, bad hardware must be to blame.

If you haven’t tried it yet, we suggest that you manually install the older yet working Android version for your device. We know this is not ideal but it’s the only effective way to allow users of Note 4 to continue using their devices that suffered problems after installing Marshmallow and/or Nougat.

Problem 9: Galaxy Note 4 screen showing green strip on top, screen remains black and won’t turn on

I had my phone in my bag on a chair and when I went to go get it and my bag was on the floor. There were scratches on the front of it. The screen is totally black but when I 1st tried to turn it on there was a green strip on the very top of the screen that appeared. There is a blue light blinking on top (like my email notification) and the lights at the bottom still work. I have the Samsung Galaxy Note 4. — Brittany-cats

Solution: Hi Brittany-cats. Boot the phone to Recovery or Download mode and check if you can get the screen to work normally. If that green strip on top remains when the device is on Recovery or Odin mode, you’re out of luck. That’s a sign of a damaged screen and you must have the phone repaired or replaced. The same is true if the screen stays black and won’t show anything.

Here are the steps on how to boot the phone to Recovery Mode or Download mode:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.
