Problem #1: Galaxy Note 5 restarts on its own

My phone is shutting down and restarting by itself at random times. I can be charging or not, in a call or not, App open or not. I cannot find a pattern as to when it does it. While typing this it has restarted twice. The cellular signal continues to go up and down as well. One minute I have full bars (while it is sitting on my desk) and the next minute it has nothing. Sometimes restarting the unit will get signal back, other times it makes no difference.  This phone is less than 2 months old and has not been exposed to water or damage of any kind.

I have cleared the cache, completed factory reset, and removed most all Apps.  All of the problems still exist.  can you help or is it toast and time to go back to the factory? Thank you.

I completed a factory reset on the phone and the issues. — Scott

Solution: Hi Scott. A random reboot issue on an Android device can be caused by one out of many factors. The general rule of thumb when dealing with it though is by checking first for possible software causes and if nothing works, assuming that you may have a hardware malfunction at hand.

An average user is usually helpless when it comes to diagnosing and resolving possible hardware problem simply because the procedures are advanced and requires electronics skills and knowledge. Tinkering with hardware also demands experience as well as specialized kits. These are some of the prohibitive reasons why we keep away from providing tips on what to do with hardware issues in this blog.

The only solutions we provide for random reboot issue are limited to software. You’ve done most of them so there’s really nothing much that you can do right now. We think that you have a hardware issue though so you must submit your phone for checkup so repair or replacement can be done.

For educational purposes to other users who may encounter the same problem but with a different cause, we will provide the same solutions here but with the explanation why each one may work.

Wipe the cache partition

Android stores important, temporary system files in a location called cache partition in order to work efficiently. This cache makes loading of apps as well as the general performance of the phone move faster. At times though, the said cache can become corrupted after an app or system update, or even simply due to the normal day to day firmware operation. A bad system cache, needless to say, can lead to performance or some other forms of issues including reboot problems. To maintain a good system cache, a user must regularly refresh the cache partition. This can be done once every few months to keep phone performance in top shape. To clear the cache partition, simply follow these steps:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Boot in safe mode

Some cases of random restart issue are due to bad or poorly coded third party apps. Users, most of the time, install apps without checking if they come from a reputable developer of not. Incompatible apps can result to operating system stability issues which, in turn, can also lead to other issues like random reboot experience for some users. Because there’s no way to know for certain which of your apps may be causing the issue, a method adapted from personal computing platform is used by Samsung, in the form of booting in safe mode, is used. While safe mode is enabled in your device, all third party applications, that is all the apps you’ve installed that are not from Google and Samsung, will be prevented from running. If your phone works normally and random reboot won’t happen while safe mode is on, that’s a confirmation that one of your apps is to blame. Safe mode still allows you to send and receive text messages, make and receive calls, and use pre-installed apps. We recommend that you observe your phone in this mode for at least 48 hours. That gives you enough time to watch how your phone behaves.

In order to boot in safe mode, kindly follow these steps:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.

Uninstall apps

This solution is the logical follow up if you’ve found out that the random reboot issue does not occur when you boot your Note 5 in safe mode. Poor quality apps abound in Google Play Store as well as in other third party app depositories so it’s always an unwritten rule for users to be wary of them. In reality, there’s no easy way to distinguish a bad app from good ones so there’s a chance that you may have installed a bad application right now. Since there’s no precise way to identify which of your apps may be creating a conflict with the system, your only way to move forward is by removing apps until the issue has been eliminated. We know that this is a time consuming process but it’s an effective counter to fix a problem due to a bad app.

Check disabled apps

If you are the type who wants to disable apps and services you don’t recognize, there’s a chance that you may have unintentionally turned off a critical system app. To check, follow these steps:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the Disabled tab.
  • Check the list of all disabled apps and try to turn everything back on.
  • Observe how the phone behaves in the next 24 to 48 hours.

Check for overheating

Overheating and random reboot issue often go hand in hand. An Android device, especially Samsung ones, are designed to automatically shut down if the temperature of certain components in the motherboard reaches a certain level. This behavior is meant to protect the device from further damage from heat. If you noticed your phone becoming uncomfortably warm lately before it eventually shuts down, overheating may be causing it.

Now, overheating in itself is not a problem but rather just an indication that something is wrong with either the hardware or, in some rare cases, software. Again, if you suspect software is to blame, you have to do the things we mention above for potential solution.

Do a factory reset

Finally, if nothing appears to work a master reset, also known as factory reset, may be the only way to go. Please refer to the steps below on how to do it.

Submit phone for repair or replacement

If all the software troubleshooting mentioned above won’t change anything, call Samsung or your carrier so you can request for repair or replacement.

Problem #2: Galaxy Note 5 installs Marshmallow updates on its own

The Marshmallow software has downloaded itself to my phone three times now. It wiped out all of my personal settings, it took away one of my favorite features of my phone, the unlock effects, my choices, completely gone! I think the update is stupid, and what’s worse is that whoever came up with this idea that’s it’s ok to mess with customers phones and their personal settings and leave us no choice, install now or install later? I didn’t want to install it at all, but you took that choice away from me! I know I’m not the only customer upset about this,  I want my phone back just the way I had it! It was perfect before you ruined it with your so called enhancements to my phone! I want my sparkly bubbles back! — Ginger

Solution: Hi Ginger. If your phone receive updates via over-the-air (OTA), you must talk to your carrier about it. There are two common ways to install Android update — OTA and manual (via Odin mode). OTA update is initiated when you receive an alert that an Android update is available. Then, depending on your device’s settings, your phone may or may not proceed to download and install the update with or without your explicit permission. The availability for the option to permit an OTA update to be installed varies by firmware and carrier. You must call your wireless carrier to know how to enable it, or if it’s even available for your device. Not having this option is NOT our fault or Samsung’s! If losing “favorite features of my phone, the unlock effects, my choices” transforms your digital life into hell, contact your carrier and ask them for a resolution.

Now, you should know an important thing about an Android update. Every time you update from one Android version to another, you can expect to lose your customizations as well as some features you may have come to love. Some Android updates are designed to bring about cosmetic changes so the looks of your phone may significantly change after the installation. If you don’t want to lose settings, make sure not to install Android updates. Again, if your phone does not give you the option to delay Android update, let your carrier know about it.

Problem #3: Galaxy Note 5 has multiple issues

There are several problems:

 

  • Device charges slowly and discharges quickly.
  • It tries to download and install apps from Play Store that I don’t want.
  • It is running very slowly.
  • Tried to do a forced reboot as advised from your troubleshooting tips and that screen is in Japanese or other language like that.
  • It has issues downloading and sending pictures.
  • Last but not least, it constantly says it is out of space and can’t download anything like apps or pictures.

 

This is a 64GB device. I have had for only 2 weeks and have only downloaded 4 or 5 apps. Was doing all of these things before downloading them. The space issue is more frequent now. It is running on StraightTalk and has not downloaded any system updates. Thank you. — Jeff

Solution: Hi Jeff. The first thing that you want to do is factory reset. Here’s how:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Once you’ve restored the device to its factory settings, let it run for 48 hours without installing any apps so you can observe how it works. If the first three issues remain even when the phone is “clean,” you must have a bad phone, or even an expensive knockoff.

If this device was bought outside your region, like from Asia, there’s a chance that you may have a fake Galaxy Note 5.

We can’t also eliminate the fact that it may be a compromised device since it downloads stuff from the Play Store on its own.

As a resolution, consider getting a replacement device if that’s possible. Otherwise, there’s really nothing much that you can do about it.

Problem #4: “Unfortunately Gallery has stopped” error on Galaxy Note 5

I recently opened an eBay store so I’ve been taking a lot of pictures. Late last night I heard the notification sound so I swiped down the status bar (without my glasses on) and I noticed a message saying that I had too many apps running. so I clicked on it and it took me to a screen that said “select apps to close.” there were only 3 on to choose from, so I just assumed that those 3 were the ones causing issues so I selected all them and hit ok. Other than that, I received a pop up saying it was due for an update so I selected for the update to be performed through the night. This morning everything seemed to be working appropriately until I tried to open my gallery. I get a pop up saying “Unfortunately, Gallery has stopped.” I have tried everything to no avail. Please! can you help me? Thanking you in advance. — Shawn

Solution: Hi Shawn. If this error started popping up after installing an Android update, make sure that you wipe the cache partition and perform a factory reset. Kindly refer to the steps above.

Problem #5: Galaxy Note 5 won’t turn on after it was dropped and got wet

I have a Samsung Galaxy Note 5. I can’t turn my phone on at all. I tried all the steps there can possibly be. I tried charging my phone but it won’t even turn on or charge at all. About a month ago, I dropped it on the floor and found it 3 days later after that, and it was raining for the past 3 days. When I found it I tried turning it on and the battery died out. It started acting up. The battery was good until my phone got rained on. I recently found my phone under the passenger side of my dad’s truck. It was probably left in there for about 4 weeks. I tried me turning it on and charging it. Nothing seems to work. I hope y’all can help me. By the way my dad bought it at a pawn shop last year in December. It’s a used phone. I just hope I can get it back on again. — Angelina

Solution: Hi Angelina. Well, what can we say? Dropping an electronic device and exposing it to water are the two worst things a user can do to effectively devastate it. The only hope for you here is to check if the device still responds if you boot it to another mode. You must, of course, leave it connected to a charger first for at least 30 minutes to ensure that the battery is properly charged. After that, try to check if you can start the phone in Recovery mode. Here’s how:

  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.

The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options. If the screen remains black though, you can safely assume that you have a hardware failure. Have the phone replaced or repaired.
