Below are specific topics we’re bringing for you today:

Problem 1: Galaxy Note 4 won’t install updates

Hi. I have just attempted to install latest software update from Samsung but install will not complete 100%. I am getting a screen appear giving me various options Reboot system now, Reboot to bootloader, Apply update from adb, Apply update from sd card, Wipe data/factory reset, Wipe cache partition, Mount/system View recovery logs, Power off. I have already tried wipe cache partition and reboot options and reboot but nothing changes. I am anxious as I do not want to lose personal files. Any ideas Thanks p.s: The phone is a Note 4. — Martin

Solution: Hi Martin. Can you select “Power off” and restart the phone to normal mode? If you can, simply turn the phone off and ignore the update notification once you restart the device.

If you can’t select Power off for some reason, you have no other choice but to do wipe data/factory reset. An issue like this is usually fixed with a factory reset so this is the only option for you right now.

Problem 2: Galaxy Note 4 stopped charging after it was accidentally dropped

Hi. My Galaxy Note 4 phone was just charging no problem at all in the afternoon. This evening, my daughter dropped on the ground and the back battery cover fell and realize tonight the charging no longer work. I tried turning off, pull out and plug again it did not work. I also tried using a portable charger, it was charging for one split second and it’s not charging again. Please kindly assist me with this issue. Many thanks. — Chengkaryan

Solution: Hi Chengkaryan. A charging problem like this is most likely caused by bad hardware, like a possible malfunctioning charging port, so there’s no amount of software tweak that you can do on your end to fix it. Try to use another charger and USB cable to see if that will fix it. If nothing will change and if the phone can still power on, you should try to do a factory reset. This will allow you to eliminate possible software bug that may be causing the problem. Here’s how to do it:

  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.

Now, as we said earlier, the main reason for this problem is bad hardware so if factory reset won’t fix your problem at all, you need to send the phone in so it can be repaired or replaced.

Problem 3: Galaxy Note 4 keeps shutting down on its own, won’t power back on

My Note 4, at first experienced random quits and shut offs. I followed some trouble shooting advice of removing the SD card to see if that would alleviate the problem but it still shut off. Usually I had to take out the battery before attempting to restart but now the phone wont power up at all. Do I need a new phone? I’m trying to hold out for the Note 8 in August. Please help. I can’t determine the OS because the phone will not power up. — Klee4.1.kl

Solution: Hi Klee4.1.kl. The first thing that you want to do right now is to check if you’ll still be able to turn the phone back on to other modes. If you can, there’s a chance that you can still fix the problem with a software solution. Below are the steps on how to turn the phone back on to other modes and the respective follow-up troubleshooting that you can do afterwards.

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 S7 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 S7 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.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If your phone remains dead or won’t boot to any of the boot modes above, the only other step that you can do is to get a new battery. One of the usual reasons for random reboot or complete failure to boot issues is bad battery. If you’re lucky and the issue lies on the battery only, getting a new one should be an easy fix.

If the problem stays even with a new battery though, send it in for repair or replacement.

Problem 4: Galaxy Note 4 can’t share via SMS

Everytime I try to share anything through a text, I get a pop up to choose existing contact or new contact. I choose existing and it freezes. I can’t choose a person or close it or anything. I have to wait for it so pop up with “Contacts isn’t responding, Do you want to close it?” If I hit wait, it stays frozen. If I choose close, it closes and goes back to home screen. So I can share anything through texts! HELP!!!! — Mlfarque

Solution: Hi Mlfarque. To fix the problem, clear the cache and data of both the Contacts app and Messaging app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Note: Hitting the Clear Data button will erase your messages and contacts so make sure to back them up using Smart Switch before proceeding.

Now, if the problem remains after wiping the cache and data of both apps, you must

contact your carrier so they can help you with it.

Problem 5: Galaxy Note 4 keeps turning off after an update

Over the past 3 weeks, possibly after an upgrade, my cell phone turns off intermittently. I have received messages

  1. “Normal Boot MMC Read Failed Error”), and
  2. the “Downloading” do not turn off target “error.

I have replaced the battery with a new original Samsung battery and have already done a hard reset. The problem comes back after a few hours and it us frustrating. Is there anything else I can do? Regards. — Mike

Solution: Hi Mike. Try observing the phone while it’s on safe mode and see what happens. It’s possible that the problem is due to an incompatible or buggy app. If it’s not an app problem, you will most likely end up with a replacement phone because there’s no other way to know what is causing the issue.

If you want to try flashing, we recommend that you do the bootloader first before the firmware. Below are the general steps on how to flash a bootloader. The exact steps may vary on your phone model so try to do some research before doing the actual procedure. The steps below are meant to give you an idea on how flashing is done:

  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 6: Galaxy Note 4 “could not do normal boot …” error

My sister’s phone has been acting up the last couple of days. Lag, turning off by itself. Then today it did up upgrade on her phone. And now there is an error message. Could not do normal boot. ddi mc_ read failed Product name current binary samsung offical system status custom recactivation lock off knox warranty void. Qualcomm secureboot enable CSB AP swev st t1 a1 a1 p1 secure download enabled udc start. And I removed the battery and it won’t do anything. The screen is frozen.         — Rose

Solution: Hi Rose. Please refer to our suggestion for Klee4.1.kl above. Remember, if the phone becomes totally dead, your only option would either be repair or replacement.

Problem 7: Galaxy Note 4 screen won’t turn on when pressing Power or Home button, screen discoloration

Samsung Galaxy Note 4. Problems started a week ago.

  1. Phone screen will not turn on when pressing home button or power button. Took out battery to restart but two full tries for screen to stay on and phone work fine for about 12 hours. This happens every day so I have to take battery out everyday. Phone screen will turn on if I receive a call which seems to wake up screen and works properly for awhile.
  2. Also, started noticing when screen is about to go black due to inactivity, it flicks green and sometimes gray.
  3. Restarted phone, and the Samsung logo was yellow instead of white then it went dead. Had to take battery again to restart.

Phone has all current updates and hasn’t been dropped recently. The unresponsive screen also happen on safe mode. Any ideas to save this phone? It has only been 18 months. Thanks. — Patricia

Solution: Hi Patricia. We witnessed this issue happening on devices with malfunctioning or old battery. At 18 months, your phone’s battery can be considered ripe so if you can, try to get a new battery so you can compare how the device works with it.

You can, of course, do the basic software troubleshooting like the cache partition wipe and factory reset to eliminate possible software causes. If nothing will change after changing the battery and factory reset, you can assume that there’s a more serious hardware problem involved. In that case, consider repair or replacement.

Problem 8: Galaxy Note 4 stuck in boot loop after an update

After an update yesterday, my Samsung Galaxy Note 4 went into a repeating boot cycle. I couldn’t even start it in safe mode. After deciding to perform a factory reset I could finally get it to turn on. But now I’m having huge issues with the internal storage where from a restart it tells me I’ve used 7GB out of 16GB, but within 5 minutes it has gone up to nearly 9GB and i wasn’t even using the phone! Within an hour or so it fills right up to the 16GB causing everything to shut down, forcing me to restart the device. When it starts back up it has gone back down to 7GB and begins building back up again. I have screenshots of this happening over a 5 minute period and also a screenshot of the device details. If any more info is needed feel free to ask and thank you so much for your time. — Ross

Solution: Hi Ross. We think we’ve heard of this issue before on a different device but we couldn’t find the right article. We thought then that it was an isolated case but since you’re now experiencing it as well, this may not be isolated but rather a firmware coding issue. Since a factory reset won’t help in this case, the best option that you can do now is to attempt a manual installation of the previous stock firmware via flashing. We know it’s not an ideal solution but it’s an effective one if you wish to continue to use your phone. If you haven’t heard about flashing, try to do some Google search about it and make sure to use a good guide if you decide to flash your phone.

Once you’ve flashed the older firmware, probably Android Marshmallow, contact your carrier and let them know about the issue. We assume that you only update via OTA (over-the-air) but if not, you should talk to the developer of the firmware you’re using or get help from other users who may also be using the same firmware.

Problem 9: How to fix a Galaxy Note 4 that won’t stay on when not connected to a charger

Hello, I had a very big problem with my device that keeps restarting whenever I won’t charge it. It shows green flickers and restarts automatically, this problem frustrates me very much. I bought this phone like 3 years ago and this problem occur one year ago. I tried all of the suggestions in the internet, I “factory reset,” I “clear caches” all of my apps and I even upgrade my phone to “Marshmallow 6.0.1.” The previous version of my phone is like 5.0 plus and once I upgrade to “Marshmallow 6.0.1,” the problem is getting worse. But one thing that prevents my phone from restarting is by charging it. Uggghh, should I charge my phone every time when I use it???

The subscriber said that the technician CHANGE THE MOTHERBOARD??? Really, this is problem of my phone that keeps restarting automatically? I don’t want to cost money!!! And my question is, IS THERE ANY SUGGESTIONS TO FIX MY PROBLEM WITHOUT COSTING MONEY? Suggestions I’ve tried: * Factory reset * Clear caches * Software update. — Nathanael

Solution: Hi Nathanael. Sometimes, random reboot issue, like the one happening on your phone, can be caused by an overheating CPU. Try to slow down the CPU of the device by setting it to Power Saving Mode. Here’s how:

  1. Touch Apps
  2. Tap Settings.
  3. Tap Power saving.
  4. Tap the Power saving mode slider to enable it.

If enabling Power saving mode won’t work, replace the battery. This should help fix the problem. If the issue remains though, it’s probably the time to consider getting a new phone.

Problem 10: Galaxy Note 4 has no signal reception after motherboard replacement

I have a Samsung Galaxy Note 4 LTE. Originally Unlocked. While my phone was under warranty (but now expired) I sent it to Samsung for repair under warranty: The phone USB port was very difficult to engage. They did not fix it stating it was ok; they returned phone without any repair. Recently, inside the USB port the metal contact became loose from its seating place (left side of usb I think it is for DATA). I could not insert USB charger anymore. I got from local phone shop a USB PORT Flexi circuit board Ref: SM 9005, REV 1.1, LTE, also it has the Antenna & Mic on it. But did not work. the phone was heating up when on charge and NO signal. I replaced my old USB port but there is NO reception. the rest of the phone functions properly. When I am outside I get very little reception on & off, but no signal indoors, states emergency calls.

Also, when outside near a transmitter I get full signal. I purchased another USB PORT Flexi circuit board Ref: SM 9005, REV 1.2, SI 1414, LTE, This still has no reception indoors when outside I get very little reception on & off. But the phone is charging properly. My phone is working 100% with my computer, kies 3 and others software, no problems. I replaced a new antenna wire but still no reception. I have tried other SIM cards still NO signal indoors. did factory reset many times. PLEASE CAN YOU ADVICE ME WHAT COULD BE THE PROBLEM. — B.miah

Solution: Hi B.miah. We can only give you an accurate answer if we can physically check the phone ourselves. We also don’t know if the circuit board you’re using is actually working properly. It’s common knowledge that there are a lot of online merchants that sell defective motherboards to unsuspecting buyers. The problem is, there’s no way to know if a purchased unit is working or not. The only time that you’ll know if it’s problematic is when there are problems that show after a repair. If the rest of your phone’s functionalities are working except the signal reception, the most likely problem must lie on the device’s modem. Sometimes, installing an update can fix network problems after repair so make sure that you do that too. If that won’t work, you should consider letting a professional check the device for you.
