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

Problem 1: LG headset connected to Note 4 won’t play any media

Even though it says media and call are connected on my LG HBS760 headset, it will not play media. I was walking into work listening to an audio book and it just stopped. When I got in and looked at the audible app it still showed that it was playing but I couldn’t hear it. I called my daughter and was able to hear fine. I restarted both devices, disconnected/reconnected BT, unpaired/paired, turned media off and then back on with the device, removed the battery, tried other media apps, and whatever else I could find online and still the media does not sound on my headphones. When I first press play I can hear like muffled crack on my headset but still no sound. Unsure what is going on and why it stopped working out of nowhere. NY phone was secured in my purse and I was heading into work and instantly nothing. Please help me. — Kidztaylor

Solution: Hi Kidztaylor. We don’t know of any instance a headset similar to the one you have decides to pick to block media content from being played. In all cases, the issue is either a total headset failure, or an unknown glitch in the phone  or  with an app. Since the basic approach of unpairing and re-pairing did not work, we suggest that you try the cache partition wipe first. This is to ensure that the system cache is deleted and replaced with a new one. Here’s how it’s done:

  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 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.

System cache is basically a set of temporary files that are used by Android to load apps efficiently. If these temporarily files get corrupted after an update or app installation, it may result to problems. Wiping the system cache won’t result to data loss but gets rebuilt over time so make sure that you continue using the phone as normal. The more the use it, the more efficient the system cache becomes.

If wiping the system cache won’t work in this case though, you then want to try wiping the phone instead. That’s done by performing a factory reset. If you haven’t tried it before contacting us, be sure to do it. It should fix your problem. Follow the steps below:

  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.

If the headset still fails to play any media after wiping your phone with factory reset, connect the headset to another phone to see if it works or not. That’s the only way to see if the problem is headset-related or not. Alternatively, you can do this simple troubleshooting first before doing a cache partition wipe and factor reset on your Note 4.

Problem 2: Galaxy Note 4 keeps rebooting, stuck in boot loop

Hi. I found your site while troubleshooting trying to fix my Samsung Galaxy Note 4 stuck in a boot screen loop. At first I tried deleting the cache like you advised and it worked for about an hour. Now it’s stuck in the boot screen again and no other tricks are working. My question is will I be able to extract pictures in safe mode? I want to do a factory reset but I need the pictures on the phone! Any advice on how to do that? If I wasn’t clear please send a reply and I will gladly offer more Info. Thanks! — Equalmass

Solution: Hi Equalmass. Yes, you should be able to transfer files in safe mode. If the phone won’t boot loop while in safe mode though, that’s an indication that a third party app is causing the problem. Be sure to uninstall apps one by one so you can observe how the works after each uninstall. This will be the only way to identify a problematic third party app.

If your phone will continue to boot loop even when it’s on safe mode, you must then try to wipe the system cache and/or factory reset (steps provided above).

Finally, if nothing will work at all, you should then try to flash the bootloader back to stock. There’s no guarantee that it will work in your case but it should be the last troubleshooting step that you can try in your end. Below are the sample steps on how to do it. Exact steps may be slightly different in your particular phone model so be sure to look for a good guide online. The steps we provide below are only for demonstration purposes:

  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 3: Galaxy Note 4 is dead, won’t power on

Hello. I have a Galaxy Note 4. It has been dying at 25 percent for around months now. Recently, within the last 2 weeks, it has been going very slow, freezing, then rebooting regardless of a full charge. I got a message that said “Downloading, Do not turn off target.” This happened a total of 3 times (at different points in time). I removed many Apps, videos, and pictures from my phone in an attempt to clear up memory. I only had 2 GB of space free. I was able to free up an additional 4 GB, so I have 6 GB free on the phone. It still kept going slow, freezing, and rebooting.

Well, this morning the thing just straight up died. It is on the charger, but is cold as ice. I’ve tried a soft reboot, a hard reboot (holding the power and volume buttons, or power home and volume) but nothing is working. The thing is just dead to the world. I’ve removed the battery and tried to reboot, and still nothing. WTF is up with this thing? My suspicion is that the phone is okay, but the battery is dead. Thoughts? I don’t know what Android Version I am running. — Anthony

Solution: Hi Anthony. If your phone is totally unresponsive and does not turn on when doing different hardware button combinations, there’s very little that you can do about it. To see if it’s a USB cable or charger problem, make sure to use a different, known working cable and charger head. If nothing changes, replace the battery. If the phone remains dead, send it in for repair or replacement.

Problem 4: AT&T Galaxy Note 4 can’t finish Android update, won’t factory reset

I bought an AT & T Samsung Galaxy Note 4 from someone on Offer Up. Well I unlocked it from AT & T and it was working until yesterday. It began glitch in and wouldn’t allow me to use anything on the phone unless it was through an AT&T app. So I factory reset it. Now, since yesterday, my phone says it’s updating 59 of 82 apps. I don’t have that many apps on my phone. This morning it still stated the same thing. My phone is way slower and no matter what I do, it still remains the same. My service is through metroPCS. I don’t know if there is a free way to unlock completely, and get rid of AT&T apps and info or not. But please help me. — Desaree

Solution: Hi Desaree. If this is an AT&T phone originally, that is, it was built by Samsung for AT&T, then the most that you can do is to network unlock it. By network unlock we mean changing some phone software settings in order for it to work with a non-AT&T network. Network unlocking though does not mean complete removal of AT&T software from the phone and replacing it with a different one. When your phone is network unlocked, only a small portion of the entire software is reconfigured. The phone is still essentially an AT&T phone, running an  AT&T software. Apps that were pre-installed together with the AT&T software can not be removed at all although you may be able to disable them. The most that you can do in this case is to reflash the device, meaning install an updated AT&T software or a custom software/ROM. You should not flash or install a metroPCS software in an AT&T phone. Doing so is a sure way of bricking your phone.

Now, keep in mind that flashing or installing a new AT&T version on this phone will reconfigure the entire system, which means that you may have to pay a shop again to have it unlocked. This varies by phone models though so make sure to do more research about it. Try to visit websites and forums like XDA-Developers forum to get ideas how to flash your device. Each flashing guide varies by phone model and carrier so make sure that you have a good guide before doing it. Otherwise, you may be bricking your phone for good.

Problem 5: Galaxy Note 4 charging port not working, won’t charge properly

Phone not charging. Performed hard reset, soft reset, changed batteries, changed chargers and cords. All components previously mentioned work to charge (slow and fast charging). my wife’s phone which is exact same model. I wondered if it might be a worn out USB on the phone itself, but everytime I remove the battery and drain capacitor by holding the power button, then insert battery I can plug in the charger and it connects and begins to charge everytime. This happens with the Samsung battery only. Aftermarket battery produces a constant short buzz like it’s trying to start charging but never shows that its charging.

I can also start the phone after it’s begun charging on the Samsung battery, but when I remove the charger and try to reinsert it, it does not charge.

Also, everytime i connect it to my computer, the computer says it doesn’t recognize the USB device. I assume that rules out the bad USB on the phone. I feel like I’ve troubleshot this as far as I can go and hopefully ruled out hardware.

Anyway, any advice you might have as to a software issue would be very helpful. Thanks very much. — Ryan

Solution: Hi Ryan. Firstly, there’s a reason why Samsung discourages users from using  non-Samsung batteries. If the phone appears to charge only when using a Samsung battery is in, that should be more than enough indicator for you that something is not right.

Secondly, Android troubleshooting at an end-user’s level is simple. If you’ve already tried all the basic software troubleshooting steps like cache partition wipe, booting and observing in safe mode, and factory reset, it’s very likely that the issue is due to bad hardware, which is usually beyond an average user’s ability to fix. There’s no direct way to test if a charging port works properly or not unless you dismantle the phone and check this specific hardware with a set of diagnostics tools. If a new battery (from Samsung) won’t fix the current problem, stop looking for answers. Simply bring it to Samsung or to your carrier’s shop so it can be repaired or replaced.

Problem 6: Galaxy Note 4 won’t connect to 4G network

I own a Samsung Galaxy Note 4 and have my service through AT&T but through a StraightTalk Plan. When I first switched from contract to prepaid my phone has the 4G showing and I was able to access the internet from anywhere. Even when I wasn’t connected to WiFi. For about 6 months now I have not had that capability for some reason. I’ve tried calling StraightTalk to see if it has something to do with their Plan but can never get anyone to stay on the line long enough to help me. What would be causing this to happen? Please any information would be greatly appreciated. — Belinda

Solution: Hi Belinda. We’re not familiar with your StraightTalk Plan and what services it covers so if the only different thing you did prior to noticing this issue was to switch from postpaid to prepaid, then we’re afraid the best thing that you can do is to talk to them. If you’ve already tried to selecting 4G network and restarted the phone, then there’s nothing more that you can do. In some rare cases, asking for new SIM card reportedly work in fixing an issue similar to yours so you can also try that if you want.  Kindly work with your carrier for more assistance.

Problem 7: Galaxy Note 4 charging cable is not working, won’t charge when using USB cable

Hello. My Galaxy Note 4 just suddenly stopped charging. i bought a new charger from Verizon because i lost the original cord that came with the phone. i kept the part that goes into the outlet and you attach a cord to it. so i bought a new USB charging cord from verizon and my phone has been charging great for a couple months now and now for some reason it won’t charge my phone, my battery drains really fast off of the charger, but will charge great if i use a different cord attached to the part that goes into the outlet. could you help me figure this out?

I don’t know how it could be charging just fine, but then when i hook up the cord i bought that was working just fine for two months it al of a sudden doesn’t work. Then when i take the phone of the charger when i charge it with other things the battery drains like crazy.

My phone also started vibrating like crazy then it started to flash the low battery sign at 10 percent every 10 seconds. i performed a reboot and deleted my unwanted pictures and videos. I also installed Ampere and it said my battery was good. is it my battery or just the charging cord? (confusing i know lol). –Jamielee

Solution: Hi Jamielee. Although it’s not common, a bad USB cord causing some charging problems can happen. We don’t know how you take care of this cord or under what type of environment you subject it to but based on your problem description, it’s just a cord problem. If you can see any signs of physical damage on the cord anywhere, then it’s possible that the fine wires inside the plastic covering may be cut or disconnected.

To prevent damaging a USB charging cable, here are some tips:

  1. Don’t pull out the cable by holding at the middle part. Always plug in and plug out the cable by holding the connecting part near the base of the connector.
  2. Minimize bending the cable as much as possible. Be sure to pack the cable properly.
  3. The critical parts of a charging cable are the ones at both tips. Make sure to take care of both ends to extend the life expectancy of the cable.
  4. Do not expose the cable to temperature extremes. Too much heat may melt the wire or weaken the plastic coating. Too much cold may cause the wires to snap as well.
  5. In general, take care of the cable just like how you take care of your phone. If you don’t do that, you can’t expect it last long enough.

In case your charging cable looks perfect and you have been doing the items above all along, then simply replace it.

Problem 8: Galaxy Note 4 screen cracked, won’t turn on

Hi There. I dropped my Samsung Galaxy Note 4 a few months ago and the first layer of screen cracked, but the touch is still working. I had a screen protector put on since. Today when I wasn’t using the phone, the screen went to lock status automatically, then when I touched Home button, the screen went to black with yellow and green lines, no button will work. So I tried to pull the battery out, press Power and Home and Volume Up button to drain the cache battery then put the battery on, press Power button again. the same thing happened. just took a much longer time to show the screen with lines. I had notification before that my phone storage was low, but I haven’t backed up the data yet, so can’t perform a factory reset. Can you please advise what I should do? Thank you. — FU

Solution: Hi FU. If you never had the screen replaced after you dropped the phone before, then this problem may be the result of that. Putting a screen protector in an already damaged screen won’t make it any better. In fact, it can only get worse. If you don’t want to lose data on this phone, bring it a good electronics shop so the phone’s screen can be replaced without wiping the storage device. There’s no magic software troubleshooting or solution that can fix a broken screen.

Problem 9: Galaxy Note 4 stuck in T-Mobile logo screen

I have an Samsung Galaxy Note 4, it is disconnected. It was working fine. My daughter used it for Youtube and one night it died. So i charged it overnight and the next morning i tried turning it on and it turns on but completely? What i mean is that it turns on and it says Samsung Galaxy Note 4. Tthen it changes to a colourful Samsung and from there it turns to a white screen that says T-Mobile 4G LTE and it stays there. It won’t change to the home screen at all. I tried to reboot it and nothing seemed to work. Can i get some help please i need to save all of my daughters baby pics! Thanks in advance. — Nancy

Solution: Hi Nancy. Try to boot the phone to Recovery mode first so you can try to wipe the cache partition. If wiping the cache partition won’t work, then we’re afraid you really have to try a factory reset on this one. We know you don’t want that but it’s the next logical step in this case. To boot to recovery, follow these steps:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo 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.

Although the chances that it’ll help, you can also try to see if you can boot the phone to safe mode. While in this mode, you should be able to create a backup of your files if your phone will stay on long enough. Safe mode will block third party apps and services though so you will only be able to use pre-installed apps. To boot to safe mode, follow these steps:

  1. Press and hold the Power button.
  2. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  3. Continue holding the button until the phone finishes rebooting.
  4. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  5. 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 a factory reset won’t fix the problem at all, send the phone in for repair or replacement.
