Problem #1: Galaxy Note 4 slow performance issue after installing Android Marshmallow

Despite a soft reset followed by a full factory reset, my Note 4 went on a go slow just lagging and switching off then freezing after the 6.0.1 update. I finally rooted with TWRP and used emotion ROM but the problem still exists. It lags at times as I type this and cannot multi task. It goes to black screen which when pressing the power button does nothing so eventually I have to remove battery. Always trying cache clean but no success. Will try new battery next but otherwise a new phone if problem cannot be sorted. — Frank

Solution: Hi Frank. We haven’t tried updating our own Note 4 to Android Marshmallow so we don’t have first hand experience how performance goes with this new operating system. We don’t receive a lot of cases similar to yours so we assume that Galaxy Note 4’s hardware can handle the more advanced Android Marshmallow at this time. Keep in mind that Samsung designed the Note 4 to run older Android versions and not Marshmallow so we can expect some minor performance glitches from time to time. We understand that your issue not minor at all so this may be an isolated case due a particular nuance in your phone’s hardware. If you want to continue using this phone normally, we suggest that you try flashing the stock Android Lollipop version at this time. Given the fact that there’s no way to know what may be causing the problem, this is the only effective solution that we can think of at this time.

Problem #2: Cannot delete MMS message in Galaxy Note 4

I have a Note 4 that has some kind of glitch with an MMS message. I assume since it is from an email address of an old company I used to deal with, and is an icon of an envelope with a movie reel in the corner. I go into my recent call list, select all calls and messages and delete. All other messages delete except this one. Has been there for over a year and it’s aggravating me. I’ve tried clearing cache and data from messaging apps, deleted the company from my call list. Deleted all of my SMS backups. I’m beyond frustrated. I don’t want to have to do a factory reset on my phone. When I upgraded my phone to the Note 7, it wasn’t there. Only on my Note 4. But now I’m beginning to wonder if this MMS can cause any harm to my phone or any of my information. Any help would be greatly appreciated. — Jess92c

Solution: Hi Jess92c. We don’t think we get the full picture of the issue here but if you’re having trouble deleting an MMS even after wiping the messaging app’s cache and data that stores it, then a software glitch may be causing it remain stuck. In this case, we strongly suggest that you factory reset the phone to bring all software settings and pre-installed apps back to stock.

There’s a chance that this may also be due to a message being stored in a cloud and not in your phone at all. Try checking possible linked account that keeps this message and see if it’s sync to a cloud service so you can delete it from there.

Problem #3: Galaxy Note 4 starts turning on and off after it got accidentally dropped

Note 4 EDGE Restarting issue. Mobile fell down from a height of 3 feet but was protected with cover (BOOK COVER closed) turned off…. i was trying to on it but didn’t turn on…. then i take out the battery, put it in again but didn’t turn on… connect it to charger for a while. Screen turns on and starts charging… then i turn it on from power button. It turns on and working all ok but after a while it starts turning of and on off and on… now after 24 hours, it is rebooting on the main screen (no physical damage on body and on screen as it was in its protective cover). —Kamil.zahid

Solution: Hi Kamil.zahid. If this problem started after the accidental dropping incident and was not there before it, then there’s no point looking for software tweaks to fix it. Your phone must have suffered a permanent hardware damage and there’s no amount of software troubleshooting that you can do to fix it. The shock that follows after the phone hit the surface must have dislodged, or broken some components inside. Even the most expensive screen cover can’t protect your device from devastating effects of unnecessary shocks. Putting a gadget inside a protective cover cannot fully neutralize the side effects of a bad fall so if the phone was working normally fine before and suddenly showed this issue after it got dropped, you can assume the hardware got damaged really bad.

The only thing that you can try on your end is to do a factory reset (if it’s possible given the phone keeps rebooting on its own) and see if it changes anything (we doubt it though). If the issue remains, send it in for repair or replacement.

Below are the steps on how to master 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 Vol 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 Vol 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 #4: Galaxy Note 4 can’t power back on

Hi. My dad has a Samsung Galaxy Note 4 and he has been having a lot of problems with this particular phone. He’s had it replaced multiple times because it would cut out on phone calls, and then it stopped holding in charge, and with the one he has currently shut off on Friday and hasn’t been able to turn back on.

I’ve tried pulling out the battery and draining the charge by holding the power button, and I’ve tried checking the cord and it seems to work fine but the phone still won’t turn on. And my dad is concerned that he won’t be able to get any of his phones information back, like his contacts and notes he made in his calendar.

Is there any way he could recover that info if it doesn’t turn back on? I’d appreciate any help you could give me. Thank you 🙂 — Anna

Solution: Hi Anna. Unfortunately, there’s no way to recover anything off the phone if it won’t turn on. Your main task therefore is to see if you can start the phone to alternate boot modes so you can do some follow up troubleshooting. There are three alternate boot modes and each of them can be accessed by doing a certain hardware buttons combination. Not all of them will allow you to recover information though. For example, if the phone will only respond to a hardware button combination that allows it to boot to Download or Odin mode, the only available solution for you is to flash the software. Flashing overwrites current software on the phone, effectively wiping user data information such as photos, videos, notes, and contacts saved locally. If these files were never backed up somewhere like in his Google cloud account, flashing will erase them all.

The good thing is, if the phone will respond and boot to a particular boot mode, there’s a chance that you will be able to use it again without resorting to repair or replacement.

For reference, here are the steps on how to boot your Note 4 to three alternate boot modes:

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 the phone remains unresponsive or won’t restart to any of these boot modes, try getting a new Samsung battery first. If that won’t help either, consider repair or replacement.

Problem #5: Galaxy Note 4 can’t find any video in SD card

I have an SD card that I removed from my sports camera to my phone to view the videos I had been taking (a button on the camera is broken and won’t allow me to view video straight from camera or connected to a computer). The months worth of video is missing, could be because the camera is broken and I only thought it was recording, but I know files can go missing on the Android, and weirdly one recent video shows up, but only in Instagram. That one video weirdly being available through the Instragram gives me some hope that maybe thought files are there somewhere. — Meaganbdeneau

Solution: Hi Meaganbdeneau. We’re sorry to burst your bubble here but if your Note 4 or computer can not find anything on the SD card right now, it’s highly likely that those files are gone or were never saved on the card in the first place. In this case, what you see is what you get. We don’t know what things show when you browse the card using your phone but if you can’t find what you’re looking for, they may not be there at all. For example, if you can’t find any working and/or corrupted files in the SD card right now, there’s no way you can miraculously make them appear out of nowhere.

The best thing that you can do right now is to keep the card as is. Do not use it to save something to avoid overwriting sectors that may still contain some bits that can be recovered (if there’s something there). If you insert the SD card to a different device and use it to keep other files, new data may write the sectors currently keeping readable files.

Now, assuming that your broken sports camera did save something in your SD card but those files are now unreadable by your phone or computer, there may still be hope that you can recover them using special file recovery software. If you think those files are worth several hundreds of dollars, you can do some online research to find companies that do file recovery jobs. This task is very expensive though so you are looking at paying a few hundreds of dollars at a minimum. Some companies that handle such tasks may not charge you if they cannot recover anything but others may, even if there’s no positive outcome. Successful file recovery job depends on a lot of factors so there’s little to no guarantee that you can get something out of it. Again, if you think those digital memories are worth hundreds of bucks to recover, use Google to find good companies that can help you do the job.

Problem #6: Galaxy Note 4 won’t boot to Recovery Mode | PC can’t detect Note 4 via Odin mode

Hello. My phone is Samsung Galaxy Note 4. So, i have rooted my phone long time ago and it was working fine. Today, the phone had problems in reading the microSD card. I tried rebooting, taking out the SD card and putting it back in but it didn’t work. That’s not a big problem as I have a backup file. So, all i need is a new microSD card. So, I started to reset the phone to factory settings. After leaving the phone to do its process, there is only a black screen that appeared. I took off the battery and tried to boot it. The Samsung screen appears and then black screen. I tried entering Recovery Mode but it’s not possible. I can only enter Download Mode but neither Samsung Switch nor Odin can detect my phone when it’s connected to cable and is in Download Mode. Any idea? Thank you in advance for your help. — Sivaraj

Solution: Hi Sivaraj. We don’t know the full history of your device so we can’t say for sure what happened. The phone’s inability to read an SD card may or may not be the side effect of this issue. If it doesn’t load to Recovery Mode anymore and no device can talk to it via Odin mode, you must have a bricked device. Sadly, there’s no way to directly check what’s wrong with a device with an issue like this though so you should consider having it repaired or replaced.

Problem #7: Galaxy Note 4 wifi not working

I am emailing you since of all the forums, mostly outdated ones, yours seemed the most user friendly and responsive.

I have found my uncle’s old Samsung Galaxy Note 4. He has sated it’s a P.O.S. since it does not work on wifi. I’ve done a little research online and came upon your forum and email address. The problem is that the wifi will not turn on. I am not tech savvy whatsoever so all that boot firmware talk just confuses me more. I have concluded it to be something along those line or an issue with the application KNOX pre-installed on the phone.

I have connected it to KIES3 and it states that the firmware is the latest version. When I press the wifi button, an error appears: “The device has detected an application attempting unpermitted actions and has stopped loading. To protect your device, it is recommended you reboot.”

I have included 3 pictures, one of the phone’s information and build number. The others are a screenshot of the phone’s security notice when I do press WiFi button and, last I’ve included a screen shot of the information that appears on KIES app when I plug phone into it. Thank you in advance for any and all information you may provide me as well as any useful links or apps that may help overcome these problem and proof my P.O.S uncle wrong. 🙂

Well you can forget that last part, as I emailed the provided and was told you no longer reply to that address. I”ll type in relevant information. Samsung phone was made to work with MetroPCS after being a T-Mobile phone. — Ricardo

Solution: Hi Ricardo. If wifi functionality does not work in your Note 4, that’s probably due to either a problematic third party app, or a software glitch.

To fix the problem, the first troubleshooting step that you want to do is to boot the phone to safe mode. While the phone is in safe mode, all third party apps and services will be blocked. If the cause is due to a bad app installed on the phone, the phone’s wifi functionality should work. Here’s how to boot 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 Vol 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 and see if wifi works.

If there’s no change while the phone is in safe mode, do a master reset. Refer to the steps above on how to do it.
