Problem #1: Galaxy Note 4 stopped booting up after installing Marshmallow update

It all began after a Marshmallow update in November 2016. The phone was quick, snappy, and with 4 large Krait 2.7GHz cores and plenty of RAM and an Adreno 420, it arguably should have the hardware to run anything an S7 can run. Yet, barely received Marshmallow before Nexus 6’s were already on 7.1.1.

Meanwhile, Samsung had pulled everyone to attempt a Note 7 salvage and then a Note 7 recall, a push to get its VR Gear ready and out from Christmas. Meanwhile they have side issues like smart appliance problems and to save face they devote the only energies left to trying to at least get ONE phone (S7) on Nougat (still not happened as of Jan 10th 2017).

At the same time a minor update or two gets pushed to Note 4s, none updating to anything beyond 6.0.1 and more importantly not fixing the “crash machine” that turned a perfectly working Note 4 into after Marshmallow. We are talking clear cache, full factory resets, new batteries, new SIM cards, pulling SD cards, nothing but pulling battery and praying it will restart. THEN suddenly I read a blog and a girl points out if you run a music player in the background, it will never crash. Guess what? Absolutely right! Run Pandora (need to leave volume on at least 1 or it will pause, closing background running, so leave it on low volume and you could open up 100 apps and runs 10 videos and it would FLY like nothing was ever wrong? Unfortunately you can’t take a call without killing the player and that spells the ends and crash city all over again. Finally, two days from our Pixel XL delivery, the Note 4 now is total blackout, no response to changing, new batteries. Zero signs of life. An attempt to plug into my Mac recognized nothing. I’m about to get out the PC we have (Yoga 2 Pro i7) and see if it can see anything, but there are no signs of life and initial attempts to drain battery from RAM yielded nothing. But it seems our only hope? Can you even FLASH a phone when it shows no response to power or does not recognize by a laptop?

After that, background music player workout I feel it’s 100% software somehow, even if it lay in power management code. I think Samsung has to know it nearly bricked all Note 4s and is spread so thin it won’t admit these phones need patches STAT! Thoughts? I just want to get mine to power on so I can even get my trade in credit! Heck, the phone specs are so good I shouldn’t even NEED a new phone? Am I right on any of this? — Kevin

Solution: Hi Kevin. First of all, if the main concern here is on how to power back your Note 4 on, you must try all the usual dose of software troubleshooting steps for this issue. These steps include:

  1. using a different charger,
  2. using a new battery, and
  3. restarting the phone to different boot modes

If you’ve already tried another charger and battery before contacting us, then the only remaining step you need to do is to see if you can boot the phone to other modes. Keep in mind that booting to safe mode is not a solution in itself, but rather a way to possibly do something about the issue. For example, if your phone only boots to Odin or download mode at this time, there’s a chance that you may be able to solve the issue by flashing a stock firmware. Below are the steps on how to boot your phone to different modes:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • 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.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • 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.

In most cases, if you’ll be unable to power a device back on to any of these modes, it usually means that there’s a hardware malfunction involved. In this case, we suggest that you bring the phone to a Samsung service center for repair or replacement.

Secondly, if you think Samsung updates is the sole cause of this disaster, you should contact them directly. We are not Samsung so there’s little to nothing that we can do in terms of resolution. The only way we can be of help is to publish your situation so other users will become aware of this issue. For our part, we really can’t say that it’s Samsung’s fault, especially if the update is coursed through your carrier’s update system. System updates, in general, can be a package of incremental patches from all parties involved (Samsung, your carrier, Google) so there’s no way we can say that’s it’s a purely a Samsung issue.

Problem #2: Galaxy Note 4 red charging light stays on even when battery is taken out | Galaxy Note 4 keeps freezing and randomly rebooting on its own

Hello, I have been having troubles with my Note 4 over the last several days. The persisting problem is that the phone regularly turns off while charging. Even when I remove the charger and the battery, the red charging light still stays on.

There are several other problems such as the phone tends to freeze and shut off at least a couple times daily. It takes numerous tries to restart the phone (taking out the battery and putting it back in), and I also get the “Downloading… Do not turn off target” error message at least once a day. I have also tried the soft reset numerous times but the problems still persist. What do you think might be the best solution to these problems? Note: The phone is currently up to date with the software, there is an 8GB free of storage. After clearing the cache, the same problems persisted and do not have an SD card.  Thank you. —  Anthony

Solution: Hi Anthony. It’s not normal for a phone’s red LED light to stay on even when the battery and/or charger has been disconnected. The LED itself needs a battery source to work in the first place. Either you:

1.) mistakenly identified a dead red LED light as lit,

2.) or that there’s a hardware issue that causes the phone to continue supplying the LED light with power even if the power source has been disconnected.

The second situation is obviously not normal so for this to happen alone, that’s already proof of hardware malfunction. In this case, you should have the phone checked by Samsung so the hardware issue can be correctly diagnosed.

For the freezing and random reboot issues, the cause may be one and the same with the one that causes the LED light to turn on even when the battery is not inserted.

In some cases, bad software may also be to blame so before you consider having the phone repaired, you can try some software hacks first.

Update all apps

The first thing that you want to do is to ensure that all your apps are updated. You want to do this in order to minimize bugs from apps. In order to update all apps at once, simply do the following:

  • Open Google Play Store app.
  • Tap the Menu button.
  • Tap My apps and games.
  • Tap UPDATE ALL.

If you are fond of installing apps from third party sources (outside of Google Play Store), make sure that they are also fully updated and secure. Third party apps from other sources may or may not be compatible with the current Android version on your phone so it’s primary duty to ensure that they are.

Observe the phone in safe mode

In some cases, third party apps can be problematic and can lead to all sorts of problems. If you have plenty of apps installed, it’s possible that one of them may be causing the problem. To check, simply boot the phone to safe mode. While safe mode is on, third party apps and services are prevented from running. Make sure that you observe how the phone behaves for at least 24 hours so you’ll notice the difference. If you’ll notice that the freezing and random reboot issues won’t occur, that’s an indication that one of your apps is to blame. The steps on how to boot your Note 4 to safe mode is provided above.

Keep in mind that safe mode won’t tell you the name of the offending app. You must do trial and error in identifying it.

Wipe the phone clean with factory reset

Factory reset will restore all software settings back to their known, working state, effectively deleting whatever glitch that may have developed after unboxing. Because it reverts the software to its initial clean version, it’s a good way to get rid of any app- and operating system-level bugs. It’s also the ultimate software solution that you can try on your end. Like in safe mode, we recommend that you observe the phone for 24 hours without installing anything to see any difference. If the problem lies on the software, factory reset should fix it. If the problem returns after a factory reset (and without installing apps yet), the cause must only be hardware in nature. In this case, you must have the phone repaired or replaced.

Here are the steps on how to factory reset your Note 4:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem #3: Galaxy Note 4 keeps rebooting on its own

My device has been operating just as usually until one day, when I was on the internet, it powered off on its own while it still has plenty of battery. Later, it powered on on its own, but before I could touch the screen, it turned off again. This continued for hours. I tried removing the battery and waited for a few minutes before placing it back. However, once the battery is placed, the process starts again and again. I left it there for around half a day. When i went to check on it, the screen was on and it stopped power off-ing. I thought it was okay, but the next few days, i noticed that whenever I press the sound button, it powers off, then on again. Each time it powers off and on, the screen will show a setting about my SD card. Some settings will also be reset, example, the percentage showing beside the battery will disappear. The sound also automatically turns to the loudest. I only had this phone for about one and a half year. I would appreciate a solution. Thank you. — Eco

Solution: Hi Eco. Like what we tell Anthony above, this issue can be caused by a bad hardware or by a software glitch. So, if you haven’t tried any software troubleshooting at this point, we suggest that you do them first. Start by wiping the cache partition. Sometimes, system updates or app installations can corrupt the system cache. In order to tell the phone to build a new cache, you must first wipe the cache partition, where the system cache is stored. Here’s how to do that:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

If wiping the cache partition won’t make any difference, follow the rest of the software troubleshooting we provide to Anthony above.

Should the issue remains after a factory reset, the next best thing to try is to get another battery, preferably an original Samsung one. There’s a chance that the battery may have simply lost significant capacity to hold a charge, causing the phone to randomly lose power.

If that won’t work either, some other motherboard issue may be to blame. Have the phone repaired or replaced.

Problem #4: Galaxy Note 4 charging erratically | Galaxy Note 4 not charging properly

Samsung Note 4 phone was having problems not charging. Bought a new cord, it worked again, for a few weeks and went back to what it was doing, not charging. I then proceeded to buy a new battery, new fast charge and cord, this has worked for a few weeks and it’s back to the same problem again. It’s starting to get frustrating. What is the actual problem and why does it keep doing this?

I have tried many things, example, old battery with new fast charge and cord, nothing. New battery with the old fast charge and new cord, again, nothing. It won’t charge. If I finally get it, it charges for a few seconds or take hours to charge. This is unfair as the phone is only a year old. I had a HTC that lasted 3 years until the screen was completely cracked and was out dated. So I upgraded and have been having this problem with the charge for months now. I’ve never had a problem like this before with any other phone. I need this phone for work. — Ashkatt13

Solution: Hi Ashkatt13. The issue here is not about unfairness but most probably about how you take care of your phone. There’s high likelihood that the problem is phone-related. Most of the time, charging issues start to appear if a user is not careful when plugging or unplugging a charging cable to the charging port. The charging port can get damaged if one of the pins inside gets damaged if one is not careful with the charging cable. Moving the cable from side to side while it’s inserted to the port is one of the most common cause of charging problems. Try checking the inside of the port using a magnifying tool to see the condition of the pins. Sometimes, dust or dirt can find their way into the port as well so you also want to clean the charging port if you can. The best thing to do though is to let a professional do the checking and cleaning for you, especially if you suspect that one of the pins may had been bent.

Problem #5: Galaxy Note 4 slow performance issue | Galaxy Note 4 works very slow

My phone was running slowly and in general acting like it didn’t have enough RAM. It would also restart frequently, often when multiple apps were running at the same time. To fix this, I had planned to do a data wipe/factory reset and reinstall the custom ROM I had, which up until two weeks ago was working fine. The process did not go smoothly. All data was wiped from the phone, including the OS. The phone will boot into download or recovery mode, but every OS I have tried to install would not take. It has bootlooped, bricked, or had kernel panic every time. All the important data is backed up, but at this point it isn’t even a phone. I have the most recent Team Win custom recovery loaded on the phone, but the backup I thought I had is no longer there. What can I do to make sure a new OS installs correctly? At this point it is effectively a car frame without an engine or transmission. — Justin

Solution: Hi Justin. As long as you follow a developer’s exact instructions on how to flash a custom ROM, there shouldn’t be any problem. The usual cause of boot loop after flashing is mainly due to incorrect firmware usage. Keep in mind that that not every firmware is compatible with every phone model. Make sure that you’re using the correct one every time you flash. Do some research about the software first to see if other users have reported problems with it in the past.

We assume that you are aware of the risks of flashing custom software so you must accept whatever happens to your phone since you’ve decided to stay away from official software in the first place. The general rule if you encounter problems after flashing is to contact the developer of the software. Asking us, third party technicians, for solutions after flashing won’t help at all. There are thousands of custom software out there (that’s how interesting Android community is) so that makes it very challenging for even seasoned Android troubleshooters to really know the cause of a particular problem brought about by a certain software. The best that you can do is to contact the developer of the software, or engage other Android users who may have tried the said software before.

The only suggestion we can give you is to bring everything back to stock. Unroot the phone and install the original stock firmware  (probably Lollipop) and see how the phone performs. If the issue persists after unrooting and flashing, the problem shouldn’t be software. Consider having the phone replaced if you can’t bear the slow performance issue.

Problem #6: Galaxy Note 4 won’t restart

My Note 4 “will not restart.” The problem is simple — when I hold the power button and press restart, the phone will power off normally and the moment the screen goes black, the phone will freeze. I will either have to remove the battery or hold down the power and volume down button for the phone to turn on again. This is not a problem until you have to perform a software update, it renders the phone useless as the device wouldn’t restart when the phone requires itself to. The same happens if the phone is off and it’s plugged in for charging. The screen goes blank when I try to turn it on. I’ve already tried a factory reset, Kies (initialized it), Odin (flashed a new firmware), etc., but nothing has worked. Any help will be appreciated Regards. — Ahmed

Solution: Hi Ahmed. There’s no more software hack that we can think for this issue. If flashing a new firmware and factory reset did not fix the issue, there may be an unknown glitch that causes the phone to behave this way. Consider getting a replacement phone should the problem remain.

  1. Hi,

    My Samsung Note 4 is experiencing slowness and it hangs a lot. It had fell from my bed and was completely fine. i am suspecting if, there is any issue with motherboard. The system is updated to 6.01 and everything works fine. Only overall switching between apps is not seamless at all. Should i change the battery? or motherboard? I had also done partition wipe. no change!
    Please let me know possible solution.

    Regards,
    HT

  2. My note 4 has been working perfectly fine up until few days ago it got an automatic system from T-mobile, ever since it has not been the same. It keeps freezing up ad rebooting by itself. What could be the cause of that?
