Problem #1: Galaxy Note 4 random reboot issue

Hi, I have a Note 4 (SM-N910U) and it has been randomly turning off recently. This seemed to happen after the 6.01 Marshmallow update. however I cannot be 100% sure OS is the problem. Basically the device will shut down randomly. This seems to happen more frequently when the battery level is below 50%~60%. However it has happened at 80~90% before. The issue does not happen when I have the device connected to the charger which leads me to believe it is an issue with battery. I have brought two new official replacement batteries from Samsung however the issue still exists. When it’s shutdown the only way to turn it back on is to remove and reinsert battery before turning on using power button. I have also tried factory/software reset a few times without any success. Any help would be greatly appreciated. Thanks! — Andrew

Solution: Hi Andrew. Random reboot issue can be caused by one of many things. These causes include the following:

Incompatible update or app. While rare, we’ve heard of some third party apps and even official updates causing an Android device to reboot without user input. If the issue happened to start after you installed an app or update, consider uninstalling the said app or update and watch how the phone behaves.

Malware or virus. Some malware can force the phone’s processor to run continuously for hours, causing the phone to overheat and eventually reboot. Since malware are spread via apps, make sure that you uninstall suspect apps. You can check what apps or services are running in your device by doing the steps below:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the Running tab.

If you see an app or service you don’t recognize, try to find research about it online so you’ll know if it’s critical to your phone’s system or not. Don’t just uninstall or disable any app or service that you’re not familiar with as it may cause some stability issues.

Rare firmware glitch. Android versions released by carriers are not perfect and can sometimes create conflicts with other apps. Problems that result from this situation includes freezing issues as well as random reboot. Try to do a factory reset and observe the phone for 24 hours to know the difference. Make sure that you don’t install any app during the observation period.

Overheating. Overheating is usually a symptom of something deeper and not the issue in itself. If your phone gets uncomfortably hot lately, chances are there’s a hardware issue at hand, or one of the above factors is happening. Overheating is like the equivalent of pain that we experience when something’s wrong inside our body. It’s more important that we identify the source of the pain rather than deal with the pain itself. In a smartphone scenario, overheating can lead to random reboot. Random reboot in this case is your phone’s way to protect itself from further damage once the internal temperature reaches a certain point. If you experienced overheating on your phone, you must double your effort in identifying the source of the problem.

Malfunctioning battery. A decent Lithium-ion battery like the one on your Note 4 starts to lose capacity the moment it leaves the factory. After several months of usage, you can expect that a smartphone’s battery will degrade significantly in terms of its ability to hold a charge. Depending on how often you charge and discharge the battery, also called a charging cycle, battery issue may also lead to random reboot. We know though that this is not the problem in your case since you’ve already tried a replacement.

Other hardware component failure. There’s no way to know what hardware component may have failed unless a complete circuit check is conducted. Internal components are interconnected and a failure of one can result to problems with others. Since using a new battery and doing a factory reset, which should have addressed potential software issues, did not resolve the problem, you can assume that the phone itself is the problem. Have the phone checked by Samsung so it can be repaired or replaced.

Problem #2: Galaxy Note 4 stuck in Samsung logo screen

Went to sleep with a phone that was working perfectly, then woke up 6 hours later to find my screen totally blank, and the LED slowly flashing through colours. I tried to start my phone and it would get to the Opening Samsung Galaxy Logo screen and then just go blank again. Then i tried it a few more times with the exact same result.

I then pulled out the battery and held in the power button for well over a minute and then tried to start it up again. Same thing again. It would power up and start with the Galaxy opening screen then just go blank.

Then I tried a Recovery re-boot where you hold in the power, home and volume key. This would bring up the Galaxy start page, and the blue “Recovery Booting:” writing in the top left corner. This would then do one of two things; sometimes it would bring up the android “Installing system update” screen which then too would just go blank after 3-5 seconds. (The time would vary) and other times it wouldn’t even do that…

I haven’t tried to recover any of my info / pictures through Samsung Kies yet, but that’s my next move when I find a cable… Have you encountered anything similar? — Bronte

Solution: Hi Bronte. An issue like this happens if a user tries to modify the official firmware/OS, or after an incorrect rooting procedure. There’s no way an Android phone will suddenly decide to stop booting normally unless there’s an attempt to change the boot up behavior, or tampered with the official software. If you installed an app or update prior before you slept that night, consider doing a factory reset to see if it will change anything. This will ensure that you restore all settings back to default. Factory reset should bring the normal behavior of your phone to its factory state. Here’s how it’s done:

  • 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 Volume 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 Volume 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.

If you did try to root your phone or flash a custom ROM or software to your device prior to this issue, try to install the stock firmware again. If that won’t work, consider getting the phone replaced.

Problem #3: Galaxy Note 4 Messaging app becomes very slow after Marshmallow update

Hey! First of all thanks for providing this service!

I recently upgraded to Marshmallow on my Note 4, and over all it’s slow. Slow to unlock, slow to open any app, just over all slow. I can clear cache and what-not to resolve that issue. However, my text message app (factory installed text message app) is very slow to respond to my typing. This doesn’t seem to take place in other apps, just when creating or responding to text messages. I will begin typing my message, it will take about 2-3 seconds to catch up, and when it does catch up, it will autocorrect any words that I may have been typing AND duplicate them.

I don’t believe it to be a keyboard (also the factory installed keyboard) issue, as I would think that the issue would come up in other apps (ex. chrome or opera) however, it doesn’t.

Any sage advice for me? — Stephan

Solution: Hi Stephan. If wiping the cache partition did not fix the problem, a factory reset should. Refer to the steps above for the exact steps. Make sure that you create a backup of your personal data before your proceed.

Also, make sure that you delete old messages to ensure that your messages app inbox is not near capacity.

Problem #4: Galaxy Note 4 battery percentage drops suddenly | Galaxy Note 4 freezes and shuts down on its own

Hi there. I am not sure if you can help but for the past nearly 6 months my phone has been playing up. Every now and then the battery percentage drops quite a bit and if I use certain apps, (usually Snapchat) then the phone freezes and turns off itself and keeps restarting then tells me my battery is dead after a few seconds. Or really app specific it happened the other day when using Facebook and then another time with the camera. But it is really starting to get to me now. I even went out and bought a new battery to see of it helps and it has a tiny bit but not much. I have deleted and re installed Snapchat to see if it helps as that is the app it usually does it with but that didn’t help. Hope you can help. Thanks. — Alistair

Solution: Hi Alistair. This issue may be caused by bad software or app. Try to wipe the cache partition first and observe the phone for a few hours. An outdated or corrupted system cache (which is stored in the cache partition) can result to freezing or performance problems. Refreshing it may help in this case. Follow these steps if you haven’t done it yet:

  • 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 Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Should wiping the cache won’t work, wipe the phone via factory reset.

Problem #5: Galaxy Note 4 not receiving SMS

I recently switches over from my iPhone 6 to the Note 4 a month ago. A couple weeks ago is when the issue started. I would text people, then not hear from them for a couple days. When I texted asking what’s wrong, they said they sent a text to me, but I didn’t receive any texts. My one friend told me I’m the only one of his contacts that sometimes doesn’t get his messages. My mom has also tried texting me three times in row and sometimes I won’t get those messages. It’s really frustrating because I have no idea if someone texted me or not. Please help!

Also, is there a way to receive old messages that I have not received? — Taylor

Solution: Hi Taylor. Are the text messages you’re missing being sent from iPhones? If they are, they can be caused by any of these things:

Messages are being sent as iMessage. If you recycled your iPhone number, that is, simply transferred your SIM card to your Android phone, it’s possible that your friends’ text messages are being sent as iMessage. That means that other iPhone devices are still sending their messages to your number as iMessage. You must deactivate your iMessage first before using your SIM card to your Android phone so you will receive regular text messages. Refer to Apple website for specific details on how to deregister your number from iMessage.

Also, is there a way to receive old messages that I have not received? As far as we know, text messages that are not delivered successfully expire after some time to create space in a carrier’s message center. Call your carrier and check if there’s a way for them to help you.

  1. Random rebooting issue – i suffered a lot last year, I handed in my Gold Note 4 for a refurb, only to realise that a OEM battery was needed.

    I have a replacement and that started rebooting randomly a few weeks ago. I realised I had been charging my phone overnight.

    Got a new battery, and all is fine.

    Reboots occured when using camera or taking pictures, highly frustrating for an instagram user!!!

  2. Android Guy
    My Note 4 started randomly locking up/freezing then rebooting in just the last 2 weeks. I did the soft reset from the settings menu. Problem abated for a time, 12 hours or so, then began again. I then did a hard reset, booting into set up menu and wiping cache and all data. I did that twice, back to back. Problem went away for about 24 hours or so then began again. At the suggestion of 2 iPhone users, I ran 2 different anti malware apps, which found nothing. Sophos and AVG. So now I am left with the remaining options. App related or battery related. I just dont think this is a battery issue. I have changed batteries. I have 2 OEM Samsung batteries and this issue continues with either one. App related. has anybody really determined this is the cause? I am taking today to resolve this problem. I have read numerous post on several forums so far and no one absolutely states that deleting/uninstalling an app solved this problem. I wil continue looking for a solution. One other thing. My Note 4 will lock up when I receive a call. The rings normally, but the screen goes black, no buttons respond to touch. Sometimes it will return to normal function a few minutes later, sometimes it will lock up and require a battery removal to turn back on.
