Problem #1: Galaxy Note 4 showing “camera failed” error when shooting video

Hi. My Galaxy Note 4’s camera shows “camera failed” message after i start shooting a video. I dock my phone on a tripod stand and shoot videos almost everyday, Initially when the phone is cool, the video recording starts normally without a glitch. I have to pause the video in the middle and continue the recording many number of times in the recording process as per my requirement. But recently i have noticed that my note 4 gets very hot in the camera area after completion of 5-6 mins of recording with few pauses in the middle. And after a point it shows the message warning camera failed. What could be the problem? — Karan

Solution: Hi Karan. Although all smartphones today are fully capable of recording high resolution videos, they don’t usually have endurance of traditional video recorders. It’s not uncommon for even powerful flagship phones to overheat if used for recording videos for even under 10 minutes at a stretch. It takes a lot of computations for a smartphone’s processors when you’re capturing videos so if you keep getting the warning message that the device has become hot, you should pause or stop the recording to allow the system to cool off.

Getting a camera failure error is a bit extreme though and may suggest an underlying hardware issue. If the issue continues even after it has cooled off for several minutes,  you should consider having your Note 4 replaced as it can mean a camera malfunction.

Problem #2: Galaxy Note 4 shuts down on its own

I have a Samsung Note 4 International unlocked version bought from Sudan about 1 year 8 months ago. Suddenly the phone gets switched off and not rebooting. I took it to the mobile shop. They indicated a software issue and could manage to restart the phone with all the data. However, since then I am having the issue of the phone without notice getting back to the reboot mode and some times after long hours get restarted. What is the solution.  — Afiz

Solution: Hi Afiz. With the phone approaching the two-year threshold, it’s very likely that its battery may simply be dying. Lithium-ion batteries like the one in your phone gradually loses capacity the moment they leave the factory. The rate of this decline may be hastened depending on how you use and take care of your device. A lot of smartphones can start experiencing significant battery performance issues after a year of usage so your troubleshooting should also cover the battery.

For now, the first thing that you want to do is to wipe the cache partition to ensure that the system cache is refreshed. Installation of apps and updates can sometimes corrupt the system cache, which in turn, can result to erratic app behaviors. To wipe the cache partition, follow these steps:

  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 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.

Once you’ve wiped the cache partition, you then want to recalibrate the battery by doing these steps:

  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.

Should the phone continue to reboot on its own, do a factory reset and see if will make a difference. Here’s how:

  1. Create a backup of your important files such as photos, videos, etc.
  2. From the Home screen, tap the Apps icon.
  3. Launch Settings and scroll to ‘User and Backup’ section.
  4. Tap Backup and reset.
  5. If you want, you can tick the checkboxes next to Automatic restore and Back up my data.
  6. Tap Factory data reset.
  7. Touch Reset device.
  8. You may be asked to enter your PIN or Password.
  9. Tap Continue and then Delete all.

Any of these three troubleshooting procedures should fix whatever glitch is causing the problem. Factory reset, in particular, should take care of bugs both in app and software level. If the phone continues to shut down randomly after a full reset and without any apps or updates installed, you can bet had hardware is to blame.

To see if it’s a battery issue, try using a new Samsung battery first. If that won’t fix the issue at all, consider repair or unit replacement.

Problem #3: Galaxy Note 4 bottom half screen not working after repair

I have a Note 4 that I had a cracked outer glass. I successfully separated the glass from the LCD digitizer without it affecting the touch screen or anything else. Tested it and it swiped, worked perfectly and could do anything and everything that the phone should do before putting the glass back onto the LCD using loca glue. Again, I tested it several times throughout the process with no swiping problems but now that I just tested it again before putting it back together, only the top half of the screen responds to touch or swipe…NOT THE BOTTOM HALF OF THE SCREEN. Home and other two buttons are working properly. What am I doing wrong? Any suggestions or solutions I should try? PLEASE HELP?! Thank you. — Phil

Solution: Hi Phil. This blog does not provide hardware troubleshooting and diagnostics so if you want to get to the bottom of the problem, we suggest that you go over your work to see if you damaged something during reassembly. Sometimes, a damaged flex cable can lead to an issue like this so make sure that you check everything before reassembling the unit again. If the same problem occurs afterwards, the digitizer may be damaged for some reason.

By the way, the next time you fix any issue with the screen, try using a new entire new screen assembly instead of replacing only one of major components like the digitizer to avoid having this issue.

Problem #4: Galaxy Note 4 keeps on rebooting

Hello! I have been having this major reboot loop with my Samsung Note 4 since about the 1-year mark of having it (December 2016.) It seems to mostly do this below 30%, but I have noticed recently that it has done this at random percentages, such as today when it started restarting and then boot-looping every 10% (Hits 50%, loops, turn it back on, hits 40%, repeat.) My father and I called Verizon about it a few months ago, and the solution that helped for about a month was to uninstall and reinstall Pokemon GO because the version I had, since I was a very early player of the game, had some sort of issue that affected mostly the first 100,000 players that downloaded the app. This fixed it for a few months, but then it continued to get worse up until this point where I nearly had to have it on constant charge. The Pokemon GO solution no longer works, but I have not tried factory reset or messing with the battery especially because the battery holds its charge just fine.

Verizon told us it was a hardware problem, and suggested getting a new phone because it can be deadly to the phone. But the way I use to currently fix it when it is looping is to hard stop it by holding down the sleep button and plugging it into a fast/portable charger (of which I now have on me at all times so my phone doesn’t have a heart attack on me.)

If there is anything such as it being an easy software fix like the Pokemon GO solution I spoke of, I would like to know before I get into anything hardware that would cost my family money. I very much appreciate the help! — Electra

Solution: Hi Electra. If you haven’t tried the usual device troubleshooting solutions like the ones we suggest for Afiz above, we strongly recommend that you do them. This will help you tell if the problem is being caused by a software glitch or not. You want to do them right away, especially the factory reset, so you can check the phone’s performance when it’s running factory state software. Be sure not to install apps right after a factory reset so you can let the phone run without any third party app and updates for at least 24 hours. If the problem stays, get a new Samsung battery and see if it will fix the issue.

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

Hello! I’m Rachel and I’m having a major issue with my Note 4 as it wouldn’t charge nor boot up. I’ve read through the article for fixing and I’ve went through all the step yet it still wouldn’t boot up. I decided to email you guys first as I do not wish to waste money on repairs as my Note 4 is quite old already. I think it’s roughly 3 years old.. I really have no idea what is going with my phone as I’m very sure it is not water damage. My phone also has started to act up lately and showing a ‘downloading’ screen. Early today, I received a Whatsapp message so I was about to look at it when I realised that my phone’s power button and home buttons were not responding. So, I took out the battery and then slotted it back in and it never started up again. Hope the little story above can help in figuring out what is wrong with my phone. Please reply ASAP as I need my phone urgently and I hope no factory reset is required as the data in my phone is very precious to me. Thank you!! — Rachel

Solution: Hi Rachel. We don’t know what specific troubleshooting steps you’ve already tried but the first common sense step here should be to use another known working USB cable and charger. There may be an issue with the current charger so it’s a must-do.

If you’re 100% positive that your charger works, the next step that you want to do is to see if the phone can still boot up to other modes. If it does, this can mean the problem may be software in nature. In this case, you want to do the follow up troubleshooting especially those we recommend for Recovery mode. Below are the specific steps on how to boot your phone to 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 your phone boots to any of the boot modes above, there’s a chance that you may be able to fix the problem with a software solution. However, if the phone remains dead and the screen unresponsive, you must send the phone in for repair or replacement.

If you have a friend with another Note 4, try using the battery on that phone and see if it works on your phone. Sometimes, a bad battery is the cause of boot-related problems. If a new battery won’t fix the issue, proceed with repair or replacement.

Problem #6: Galaxy Note 4 started randomly rebooting on its own after an update

My Samsung Galaxy Note 4 has got into a restart mode…. The problem started happening from the last week… and most probably related to a Firmware Update. I remember to have updated the firmware in the last week…. Here are the details, can you please help.

Android version 6.0.1

Android security patch level April 1, 2017

Baseband version N910GDDS1DQA4

Kernel version 3.10.40-11071924 [email protected] #1 Fri Apr 7 14:15:07 KST 2017 

Build number MMB29M.N910GDTU1DQD2

SE for Android status Enforcing

SEPF_SECMOBILE_6.0.1_0034 Fri Apr 07 14:23:01 2017

Current version: N910GDTU1DQD2/N910GODD1DQC4/N910GDDS1DQA4 — Suju_k

Solution: Hi Suju_k. If you think the problem started after installing an Android update, you should do the following troubleshooting steps in this particular order:

  1. wipe the cache partition
  2. install app updates and make sure all apps are compatible with OS
  3. do a full wipe with factory reset
  4. install all app updates again

The steps on how to do a cache partition wipe and factory reset are provided above.

Should the problem stays after a factory reset, and with all apps already updated, the random restart problem must be caused by bad hardware. Try a new battery and consider repair or replacement if nothing changes.

Problem #7: Galaxy Note 4 won’t work with Bluetooth speaker when playing music

I have Samsung Note 4 SM-N910C. Here is the problem I got. When I connected my phone with Bluetooth speaker, it works only for phones sounds, call and notification. It shows it is connected and in the paired setting both buttons are on (call and audio ). When I play my music apps it also clearly indicate it is playing but no sound is not heard out on the speaker. FYI, I do the factory reset once. Please help me to fix it. Thank you in advance for your helpful support. — Kbglory

Solution: Hi Kbglory. You are dealing with two devices here so your troubleshooting must cover both if you want to get to the bottom of the problem. As far as Note 4 troubleshooting is concerned, the most drastic that you can do is factory reset. This will help clear any possible bug causing the hiccup with another Bluetooth device. If you already did that without any positive result, then it’s very likely that there’s an on-going incompatibility issue at play between the two devices, or that your Bluetooth speaker is malfunctioning. Because there’s only so much that you can do when it comes to Bluetooth troubleshooting on both devices, all you can do right now is to start troubleshooting your speaker and hope that there’s no incompatibility issue involved.

If you have no idea how to troubleshoot your Bluetooth speaker, try to see if the documentation that came with it can help. You can also contact the maker or visit their website to see if there’s something that you can find to fix it. Basically, what you want to do is to perform a factory reset on the speaker to revert all its software settings back to its known, working state.

If the same problem occurs after both devices have been reset, there may be a bug preventing the transmission of audio to the speaker. Such a bug can lie on the phone or on the speaker. Unfortunately, there’s no way to determine which is which so you can try to have the speaker replaced if that’s possible.

Problem #8: Galaxy Note 4 vibrates when charging

Phone will not always charge on regular 240V chargers that I’ve been using always. Chargers charge everything else. Phone will charge on connection with computer of 12V car charger. Phone did get slightly wet but not drenched and has been dried out. Phone works fine in all other respects. When trying to turn on with 240v charger connected the phone vibrates every few seconds. I have done the soft reset several times. — Paul

Solution: Hi Paul. Because the phone charges fine on another charger, that’s a clear indication that the first one (with 240V) is not compatible. Most Samsung chargers have input rating between 5V to 9V (depending on the exact charger you have) although a regular wall charger (not a fast charger) like the one that came with the box for a Note 4 device charges the phone at a steady 5V. We don’t know what you mean by 240V chargers exactly (we don’t think there’s any charger with such input rating) but if it doesn’t work with your Note 4, just avoid using it. Get an official Samsung charger to fix the issue.
