Problem 1: Galaxy Note 4 shuts down on its own even there’s enough battery | Galaxy Note 4 keeps showing Android download page

Hey, my Samsung Note 4 has been shutting off by itself even when it’s got battery life. I would have to take the battery , wait for a few minutes and put it back in then turn it on with it on charge. This is the only way of it turning on. It would not turn on with out the charger even though it would have battery life.

Also when it does turn off by itself it shows some sort of Android download, while I’ve tried to download but it would take days. What do I do ? And what is wrong with it ? Please help. —         Garciannes

Solution: Hi Garciannes. For your first issue, the cause is most probably the battery itself. If you have  been using your Note 4 for at least 2 years now, the battery may have simply lost the ability to hold a charge. In other words, it may not be working like it was before. This is normal, especially as a Lithium-based battery like the only in your phone gets older. We recommend that you try to recalibrate the battery first and see if it fixes the problem. If it doesn’t, go ahead and get a new battery.

Below 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.

For the second issue, it’s cause can vary a lot. In some cases, it can be due to a software glitch, while in others, it can due to an unknown hardware bug. We suggest that you do a factory reset and see how it goes from there. If the problem remains after a factory reset, you can assume bad hardware is to blame. In this case, you should consider getting a phone replacement.

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

  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 Volume Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem 2: Galaxy Note 4 keeps freezing, won’t turn on

Sprint Note 4 SM-N910P Power On Issue Matt Rankin to mailbag 13 minutes ago. Details: I have followed your troubleshooting guide to a T for devices that won’t turn on. Only occasionally doing a soft reset allows my phone to come on. Once it is on it freezes a lot and sometimes randomly reboots to the bootloader. Then I power it off and soft reset it 15 to 20 times and if I’m lucky it will turn on again. Do you recommend I just replace the circuit board with one like this (

Like the note 4 because of the IR blaster for controlling devices like tvs and dvd players and I want to get by on the note 4 until the note 8 comes out this fall. I do a lot of LCD/digitizer repairs for friends and I have decent soldering skills so if there is minor soldering I can do to repair my current motherboard I would be blabergasted. Let me know what you think with your experience. Thanks. — Matt

Solution: Hi Matt. We don’t usually recommend motherboard repair because there’s a long list of possible problems that can happen out of it. With motherboard replacement, you have to ensure that the board and all components in it are working fine, something that can be done quite easily. In fact, it can be very challenging even for a Samsung technician who’s equipped with complete tools to do the checking.

We cannot also confirm if the motherboard listed in that eBay link will work with your device. If you read the “Item specifics” at the bottom part of that page, it says this board is pre-owned, which means that it may be defective, or problematic. There’s no system in place to check if such board is working fully at this time but if you want to accept risk, go ahead and see for yourself.

Problem 3: Galaxy Note 4 randomly reboots, not turning on

I am having serious problems with my Note 4 device. My Note 4 turns off randomly and will not come on until battery is removed. Sometimes I will have to wait 5 mins before phone comes back on and lately it took 2 days to restart. I am constantly having to take battery out and push the power button until it comes back on. I tried to update it and it shut down as well. I bought a new battery and still doing the same thing. I tried the restart button and phone will not come back on. If you can help it will be greatly appreciated. Thanks in advance. — Will

Solution: Hi Will. Random reboot issue can be caused by a number of factors. The cause can be one of the following:

  • a software glitch
  • a problematic app
  • malware
  • malfunctioning battery
  • bad Power button
  • unknown hardware error

The first three items (software glitch, app, or malware) can be fixed by doing a factory reset. If you’ve never tried a factory reset at this time, we strongly suggest that you do it now so you can observe the phone. Make sure not to install apps and updates right after a factory reset so you’ll know if the problem is being caused by an app or not. Should the issue remain after a factory reset, you should start to consider sending the phone in for repair or replacement.

Problem 4: Galaxy Note 4 can’t make voice calls, can’t send and receive SMS

Hi. I’m hoping you can help me. I have had my Note 4 phone for several months now. it is unlocked from Verizon. After fixing some settings I was able to make it work with my T-Mobile family account and have had no problems for months until the other day. When I try to make a phone call I get a recording saying “you are unable to complete this call at this time” and hangs up. When I try to text I get “Free Message: Unable to send message – Message Blocking is active.”

My boyfriend and I are both on the same account and he originally had the same issue. However, they were able to fix his problem but because my phone is unlocked well you already know the answer to that. When it first started I was able to have internet just wasn’t able to make or receive calls or texts but now my data doesn’t work at all. I compared my network settings with my boyfriend’s phone and the only difference is that we showed was under Network Mode his was set to WCDMA however my phone does not have that option. The only options I have are: LTE/GSM/UMTS, LTE/CDMA, OR GLOBAL. I hope you can help thank you for you time. — Jessiqn75

Solution: Hi Jessiqn75. T-Mobile network uses GSM technology so any device registered on this network should show GSM or similar. Making your device work with a particular carrier requires more than just changing the network types. We don’t know the status of your device’s software so there’s nothing much that we can tell you where the problem may lie. If you recently changed some settings or installed something before noticing the problem, try to undo them to see if that will make any difference.

For more in-depth troubleshooting, you should work with your carrier’s technical support team in order to know if the issue lies on their end, or if there’s something that needs to be reconfigured in your phone.

Problem 5: Galaxy Note 4 won’t charge, won’t turn on

I had this Note 4 since it came out but last year it has broken down. It used to show the green Android guy when i power on but after leaving it unattended for about 8months when charging, its only able to show the red charging light by the side and the green battery percentage in the middle. It’s unable to turn on to display anything more. It is perhaps due to not using it for a long period of time. — Phoebe

Solution: Hi Phoebe. If the phone no longer turns on at this time, the only troubleshooting that you can do at this time is to replace the old battery with a new one. Doing so will let you know if the issue is battery-related, or if it’s something in the phone itself.

Since the device still indicates that it recognizes the charger (due to red LED), there’s a chance that you may be able to revive the phone by starting it to different boot modes. Below are the steps on what you need to do:

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.

Problem 6: Galaxy Note 4 won’t charge sometimes

I cannot charge my phone from the wall ports at all times however this is possible sometimes. although this is not caused by the charger cord because I’ve tried my charger in other phones and it works perfectly however, my Note 4 will only charge at specific times and if I unplug the charger while it’s charging and then try to plug in the charger again, it won’t work. I’ve tried to charge using a computer and it does work (sometimes again). When I connect the charger after switching my phone off it does show the charging indication and it fades away and doesn’t show the charging led orange light. I have already tried factory resetting my phone and also cleaning the charging port. I’ve read that the problem is with the firmware rather than the hardware. my android version is 6.0.1 and I’ve also read that downgrading the software would bring this a fix, if so can you tell me how to downgrade my phone. if no can u suggest a fix? — Husham

Solution: Hi Husham. We don’t know where you get the idea that it’s a firmware issue but it looks like a hardware malfunction to us. Inconsistency while charging is almost always due to either a charging port issue or a motherboard error. If the problem is firmware-related, your phone’s charging behavior should change after you did a factory reset. For this reason, we suggest that you consider getting your phone’s hardware checked so a technician can assess the status of the hardware, especially the charging port.

Problem 7: Galaxy Note 4 slow performance issue, apps keep crashing

I connected my Galaxy Note 4 to my computer to upload pics. The next day the phone said my SD card was corrupt, and all of my pics were gone. When I explore my files the files show they are there but empty. Took it to AT&T, they formatted the card and then told me all data was lost. I downloaded a recovery app and most of the pics came back, but only certain ones were recovered. pics I had in texts also show up and pics that were long deleted. Everything was fine, working fine. But now my phone is slow, freezes, programs stop running for no reason. When I try to text and choose from contacts it always freezes. My keyboard is slow, and freezes. I’m ready to break this thing! I’ve lost pics, and documents, content disappears from my phone. I’ve tried restarting, removing battery and restart, updated all app and phone software. I’m afraid to save anything to the SD card in case it becomes corrupt again. Any advice or insight would be greatly appreciated. — Jabeiler311

Solution: Hi Jabeiler311. Smartphones, especially relatively older ones, can start showing their age after some time. Keep in mind that smartphones nowadays can become problematic when they start to hit the 2-year mark. Constant usage day in and day out for years can wear the hardware as well as make the software slow down. Together, they can manifest in issues many smartphone users have come to encounter like freezing, random reboots, and severe performance issues. Giving you more detailed, in-depth explanation is beyond the scope of this article but you should accept the fact that older smartphones are more prone to errors than newer ones. We know that’s not really ideal for those who wants to continue using their devices for a few more years but that’s just how things are right now. If your Note 4 has been around (at least two years), it’s possible that the reason for your problem is simply a natural by-product of device aging. To minimize the side effects of wear and tear, consider

  1. doing a factory reset first, then
  2. uninstalling unnecessary apps.

Remember, the more apps are installed, the higher the chance of app-related issues to develop. Try to stick with official apps only and keep app number to a minimum. If that won’t remedy the situation (and trust us, your phone starts to degrade the moment it left the factory), consider getting a replacement.

Problem 8: Galaxy Note 4 can’t make calls or send SMS, | Galaxy Note 4 shuts down when turning on mobile data

Hi. I recently started having problems with my Samsung Galaxy Note 4 SM-N910G. I am unable to send messages (at times it may take a long time to be sent), cannot make calls and whenever I switch on my data, I can’t use it. The Internet says that I’m not connected to any network and most of the time, my phone will switch off once I on the data. Even though the battery level is high (80%+), the phone screen blacks out suddenly and I can’t switch it back on. I will need to take out the battery for a few minutes and then place it back in, before the phone can be on again. This happened several times a day and mostly when I switch on my data. Sometimes I can send messages and make calls, but most of the time I can’t. I’ve already went to the Samsung service counter to ask for help, but the staff was unable to aid me and tell me what the problem was. She merely told me that it may be a software problem and suggested that I repair my phone by resetting it. I did factory reset and restarted my phone, but when I switch on the data again, the phone blacked out. I think it may be a hardware problem and based on the staff, I had to repair it for $587 plus service fees of $30. I’m not sure what to do as I don’t know what the root cause is. Could you help me? — Gian

Solution: Hi Gian. The first thing that you want to do is to ensure that battery has nothing to do with the problem. Try to use another known, working Note 4 battery and replicate the problem. If the issue won’t occur with a new battery, simply replace the old one.

Should the issue remains even with a new Note 4 battery, it’s possible that a more serious hardware issue is causing the trouble. Since you’ve already tried a factory reset before you contacted us, it’s pretty safe to assume that this is not due to a software bug, which also means that it must be hardware related. Since there’s no way for an end user like you to know how to fix a hardware problem, we suggest that you get the phone replaced. Keep in mind that we’re talking about the issue here wherein your phone shuts off by itself if you try to switch mobile data on.

For your voice calls and SMS issues, we recommend that you work with your carrier’s technical support to identify their cause.

Problem 9: Galaxy Note 4 won’t charge properly

Sir / madam. I have a Samsung Note 4. The problem is when I’m charging my phone, if I charge it, it is doing just fine, but if i take out the charger from my phone and put it back again immediately then it won’t charge anymore. That’s why when I plug the charger in one place, I won’t dare transfer it to another place until it’s fully charged otherwise it will stop charging.

The phone will only charge again if I do it again for another hour or more, weird right?

I checked my charger and it’s fine and does the job. So is my battery, I just replaced it with a new one. I tried cleaning the charger pin with an air hose but still the problem persist. Please advise me on what to do. —  Apollo

Solution: Hi Apollo.

As mentioned above, a lot of erratic charging behaviors are often caused by bad hardware. To check if that’s the case, consider doing a factory reset first so you can compare how the phone works afterwards. If the problem stays, then it’s either a charging port issue, or some other hardware malfunction. In either case, you want to have the phone repaired or replaced.

Problem 10: Galaxy Note 4 battery issue, freezing, blacks screen, random reboot issues

Started three days ago. Phone kept freezing up, going to black screen, shutting off on its own, etc. I had to reset the phone twice, then factory reset the phone. Received message with the green Android character saying couldn’t do normal boot; mmc_read failed; Odin mode high speed. This has happened to me several times, never had a problem with the phone before this. I’m concerned. I did what your last article said to do. Take out battery for 10 seconds and put it back in. Seems to be ok right now. But still concerned. Please help me if you can. Thank you. — Monet

Solution: Hi Monet. Looks like you can get help from using a new battery here. The symptoms you mention (freezing, black screen, random reboots) are some of the telltale signs of a dying battery. Make sure to replace the old battery you have and see how it goes. If nothing will change, the problem may be phone-related. In that case, we’re afraid you’ll want to simply get a new one.
