Welcome to another #GalaxyNote4 post for this week. We bring you another batch of common Note 4 problems in this one so we hope that you’ll find this material helpful.
If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.
When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.
Below are specific topics we’re bringing for you today:
Problem 1: Galaxy Note 4 freezing and shutting down on its own
Recently, my phone has been lagging and the screen would freeze after I downloaded a few apps. Then one day the phone shut off and wouldn’t turn back on. I did a soft reset and it would work but the problem would happen again. Every time the problem occurs, I do another soft reset and it would work again.
One day, I got an error message that says, “cannot boot in normal mode” along with a bunch of other things. I called tech support who told me to take the battery out and put it back in after 10 seconds and it would work again. The phone still shuts off and won’t turn back on and a soft reset always works but every now and then I get that error message again that says “cannot boot in normal mode.” Again, I reached out to Samsung tech support who told me to take out the battery for 10 seconds and put it back in and it would work.
A few days ago, I uninstalled all the apps that I downloaded prior to all these issues and did a software update. The phone had been working fine ever since but the problems are coming back again. It seems to happen every time I try to charge my phone. This has been going on for over a week now and I want a more permanent solution than taking the battery out all the time. This problem happens even when in safe mode. Any ideas what it could be? I really don’t want to have to buy a new phone. — Mimiexue
Solution: Hi Mimiexue. Try to recalibrate the battery and observe how your phone works for a couple days afterwards. This procedure should force the phone to retrain Android on how to detect battery levels correctly. Sometimes, inaccurate battery readings can cause random shut downs. Here are the steps that you want to do:
- Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
- Turn the phone on again and let it turn itself off.
- Charge the phone without turning it back on.
- Wait until the battery says it fully charged to 100%
- Unplug the charger and turn the phone on.
- If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
- Unplug the charger the turn the phone on again.
- Use the phone until you drain the battery down to 0.
- Repeat the cycle once.
If battery calibration won’t work, do the more drastic factory reset. This should be the last software troubleshooting step that you must do. Factory reset returns all software settings to their defaults, which means that the device should be in a stable condition software-wise. If the problem is caused by a software bug, it should be absent after a factory reset. To get a baseline performance, make sure not to install any app right after a factory reset. Let the phone run for another couple days without any apps. Use it normally by doing texts and calls and let it run. If everything is normal and the phone does not shut down on its own at all, that’s a sign that the cause of the problem is software malfunction or a bad app. To see which of them is true, you must install apps one by one so you can observe how the phone works after some time. This will take time but is the only effective way to identify the cause, especially if it’s an app.
On the other hand, if the issue returns after a factory reset and even without any apps installed, you can bet the problem is due to bad hardware. It can be the battery so try to replace it first. Make sure to calibrate the new replacement battery before using it fully. If the problem persists, send the phone for repair or replacement.
For reference, these 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 Vol 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 Vol 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 2: Galaxy Note 4 fast charging won’t work, won’t charge up to 100%
I have a Samsung Note 4 that I bought in 2014. My phone charged beautifully within hour or less to 100%. Now, whenever I connect my phone to the fast charger, it says it’s fast charging but it charges slow. In fact, I leave it for 2 to 3 hours and the phone only charges up to 85% to 90%. It never goes past 90%. I did complete the soft reset by removing the battery for 10 seconds and restarting the phone. I also did another soft reset by removing the battery and holding the power button for a minute with no luck. I cleared my cache, and cleared any debris from the charging slot with no luck. My charger is in good shape since the day I bought the phone. I have kept it the same way since day one but I don’t know why it’s not charging fast. I have noticed one thing that when I remove the battery and place it back in and then turn my phone back on, my battery level shows as 100% but before that it would continue to show 85 to 90% not going past it. Today, i charged my phone for 4 hours and my battery level is showing at 88% for over 30min. Please help! — Abhishekmahendru
Solution: Hi Abhishekmahendru. Based in our own experience and from reports from others users with a similar problem, the cause is mainly a bad charging port. To check if that’s true in your case, below are the steps that you can try (minus the steps you already mention):
- use a different known working USB cable and fast charger
- Try a wireless charger (Note 4 wireless charging requires additional upgrade so it’s up to you if you want to try it)
- Recalibrate the battery (steps provided above)
- Do a factory reset (steps provided above)
- Change the battery
- Submit the phone for repair or replacement
Problem 3: Galaxy Note 4 is laggy and randomly shuts down itself
For a couple of months every time my phone shuts off, it would not turn back on unless i took battery out and waited about an hour. It would then be super laggy and shut itself off again. I had to install an app called wake lock to stop the screen from going black and shutting off my phone. The partial wake lock helped my phone stay on. My phone is now trying to update. It will say installing update, get to 100% then just shut off and not do anything else. I then have to take battery out, wait a while and put battery back in to power it back on. It then goes into update screen again. Please help. I don’t know how to get it to finish update so i can have phone working again. — Clarelouise1982
Solution: Hi Clarelouise1982. Android troubleshooting is more of a trial-and-error rather than a sure-fire way of identifying the cause so if you’ve already exhausted software solutions, including of course the temporary workaround of installing Wake Lock app, then you must be dealing with a hardware malfunction here. Please check our suggestions for Abhishekmahendru above. If those steps we provide above won’t work in your phone, consider a repair or replacement.
Problem 4: Galaxy Note 4 won’t connect to network after charging port replacement
I recently replaced the charging port on my Samsung Galaxy Note 4 and have since had Network connectivity problem. I have reopened the phone and made sure the signal cord is probably fitted on the small knot on the charging port , as well as one on the motherboard. I have factory reset but the problem is same. My network provider is sky mobile. When Sky SIM is in , network search displays EE, but in my bedroom you can see Vodafone, EE and Sky. When l connect to Sky , it will say not connected to sky. I called sky to help manual setting before resetting phone but nothing has worked. Please help. No money to go for formal repair. — W Laryea
Solution: Hi W Laryea. We have virtually no knowledge of your particular phone and how your repair goes so we can’t say for sure what happened. Since the phone appears to detect multiple networks at one time, this is definitely not an issue about hardware failure. There must be some configuration issue that must be worked out with your carrier to register the phone in their system again. It’s also possible that the phone’s network programming was changed for some reason after the repair so if working with your carrier won’t work, you’re out of luck. Only Samsung can check if the phone’s modem is programmed correctly or not so if you want to get to the bottom of this, you’ll have to ask their support
Problem 5: Galaxy Note 4 won’t install Android update
Hi. I have a Samsung Galaxy Note 4 that I bought in December of 2014 from Walmart and use through the Straight Talk Service. My phone is basically stuck on Android version 4.4.2. When I check for software updates it says, “the latest updates have already been installed” but obviously they haven’t. I have tried specifically calling the Straight Talk tech support and they had absolutely no idea what I was even talking about. They just kept saying, “you need to be under WiFi to update your phone.” But even under WiFi it still says the latest updates are already there. Most of my apps work well, but my phone not being on the latest update doesn’t allow me to have some features from certain apps. Thanks in advance for any help. — Marissa
Solution: Hi Marissa. If you have a computer, try to install Samsung Smart Switch to it and see if you can update your Note 4 after linking it by USB cable. If there’s an available update for your device, Smart Switch should tell you so the moment it detects your phone being connected. If it doesn’t, that means that you’ll be unable to update it via that app.
If you badly want to install a new Android update, you can do so manually via flashing. Keep in mind though that flashing is basically modifying core system files, so if it’s not done properly, you may end up with a bricked phone. Should you want to take the risks involved, go online and find a good guide on how to do it on your particular phone model. Exact steps vary by phone model. This means that a flashing guide for Verizon Note 4 may be a bit different from a guide for Straight Talk Note 4. Be very careful in using the firmware version since using an incorrect one can lead to boot loop problems.
Problem 6: Galaxy Note 4 with new motherboard can’t decrypt SD card
Hi there. I have a Samsung Galaxy Note 4 with an encrypted 64GB SD card. One week ago the device hang and by rebooting it never passed the welcome screen. Samsung told me the motherboard is not working so I replaced it. When inserting the SD card the message appears that the device is preparing the SD card / check for error which is still the current state. Using the SD card with PC, all info is accessible with file extension like jpeg and so on but cannot open because encrypted. I also tried another Samsung phone and same message comes up. After the breakdown the first thing I did was copying the whole SD card to my laptop. Any advise how to get the files from the SD card ? Would be great if yes. Thanks a lot in advance Best regards. — Karl
Solution: Hi Karl. Unfortunately, an encrypted storage medium like an SD card can only be decrypted by the device that coded it previously. Since you had the motherboard replaced, your phone is now basically a “different” phone and can no longer decrypt the card. The same is true even if you use another Note 4 or any other device. The strength of encryption is also its main weakness in this case so you’re out of luck. There’s no way you’ll be able to decrypt the SD card.
Problem 7: Galaxy Note 4 loses battery fast when not connected to a charger
Hi there. My name is Ameerah and I own a Samsung Galaxy Note 4. I’ve had it for just over 3 years now and it hasn’t been giving me problems until now. My phone’s lights of the buttons at the bottom end won’t stop flickering and if I try to use my device (even just unlocking it) it just switches off in a few seconds while I’m using it. Before it did this it would freeze and I would hold the power button for a few seconds and then it would come back on. The battery would end up going from eg. 58% to 23% when it switches back on, and the lights would start flickering again.
I’ve noticed that if I keep my phone in charge, the flickering stops and it works as normal. But I don’t like using it while it’s charging. I was hoping if you could please help me out as to maybe what is causing this issue.
I feel as though it might be the battery and I have read about opening the back and the connection with the battery and so on, but I just wanted to know if it is the battery or something else.
Also this has happened before but not as bad. before I thought it was the RAM being full. I downloaded ‘clean master’ as well as “CM security.” After about a week or so my phone worked perfectly fine. This happened about a year back. But now it’s worse. — Ameerah
Solution: Hi Ameerah. It does look like a battery problem to us. Make sure that you follow our suggestions for others above by recalibrating the battery and doing a factory reset. If those two won’t improve the situation, get a new battery.
Problem 8: Galaxy Note 4 reboots when using some apps
I have a 3-year old Samsung Galaxy Note 4. Sometimes, my phone turns off by itself and it keeps attempting to reboot (it vibrates and displays Samsung text) but does not succeed to reboot until I plug it back for charging. As soon as I plug in for charging it shows 0% battery. Within a second or two it will show the original battery percentage it had before turning off automatically. This happens when I try to use some heavy weight apps like Google maps, Uber and sometimes with Google browser.
There are days when the reboot happens 3-4 times a day and sometimes it does not happen at all specially the days when I don’t use any app, just use it to make calls. My Samsung Galaxy Note 4 was bought from AT&T but I am using it on Cricket Wireless. — FN
Solution: Hi FN. Despite some similarities of your issue with others above, we would like to think that your phone may be having a problem with its power management IC. That’s because the problem appears only at random, and only when you’re using apps that require a lot of computing resources. We still encourage you to do the basic software troubleshooting stuff though such as battery calibration, factory reset, flashing back stock firmware (if you’re running custom ROM), unrooting (if phone is rooted), and battery replacement. If all of these won’t make any difference at all, have the phone replaced.
Problem 9: Galaxy Note 4 stuck in Samsung logo screen, keeps saying battery compartment is open
Hi. I have an Note 4. I have removed the battery, left it out for an hour and tried a complete wipe. As I write this, my phone is flashing the Samsung logo and nothing else. Previous problems include physical problem, the port cover is broken. Have just replaced the Samsung battery with a genuine one (well it says Samsung on it). it comes up with a Touch wiz error and also an error saying to close the battery compartment which I have done, several times. It has been playing up for a while. I am currently in NYC but the phone is a UK phone with a UK SIM card. I will continue to try and do some more hard resets. — Barry
Solution: Hi Barry. There’s only so much an end user like you can do in terms of Android troubleshooting. If you’ve already tried a new battery and factory reset before contacting us, then the problem must be on the hardware side. The only other software trick left for you is to try flashing an older or newer Android version. We doubt that it will change anything but again, as we’ve said, there’s not much that can be done on your end. Software troubleshooting can only fix software problems. There’s no amount of resets that you can do to fix a hardware malfunction.
We can’t tell you what that malfunctioning hardware is unless a thorough hardware diagnostics is done. If you want to get to the bottom of the problem, submit the phone to Samsung so it can be tested. Otherwise, simply consider a phone replacement.
Problem 10: Galaxy Note 4 keeps dropping calls, apps keep freezing, crashing
Respected all. My Note 4 was a perfect machine till last week. All it happened sudden without any pulled activity. During random outgoing calls each day on a Mid-workings hours point 2 – 3 calls were dropped. I blamed on network as usual and moved to some other engagements, some random checks on notifications realized me that my cell is not ringing. I didn’t pay much attention and tried to get back to those missed calls which were missed because of x-y-z reason. All calls were established but without voice at either end. Since that day my all voice functions of Note 4 are retired along with application hanging concern. I consulted with an software expert who has flashed it a couple of times. It works fine with every voice function of the device for next couple of minutes after a fresh ROM. Then again silence. Sorry for the extra briefing. — Meer
Solution: Hi Meer. Since you’re using a non-official ROM, we recommend that you try to find answers from the developer of the software you’re using or from the community that also uses it. The solution to your problems may be ROM specific and we have no idea about it.
The most that we can tell you about this issue is to flash the official Samsung firmware first, and if that won’t work either, to contact your carrier about disconnected calls issue.
If you continue to experience app lock ups even when using stock firmware, you should do a factory reset and observe how pre-installed apps like the built-in Phone app works. If everything works normally when there are no third party apps installed, you can bet one of the apps you install that’s not from Samsung or Google is to blame.
