Problem #1: Galaxy Note 5 overheating and drains battery fast

My Note 5 is giving me so much pain. Need serious help.

From the very beginning my phone keeps getting very hot and the battery drained very first. For that i googled and found many users of Note 5 having this problem. It causes for wakelock. Android OS and Android system runs 100% of the time. I enable power saving mode, no background process. I do not keep active, battery optimization of all apps and I installed Greenify – nothing happens.

When i saw “show CPU uses” i found – after screen lock too many app running in background but when I unlock apps are killing of. To resolve this issue i connected the phone to a PC but it couldn’t recognised it. First i change the cable. Nothing happened. Then i install latest drivers and Kies. Same result. Then I tried to root without PC. But i don’t find any APK to root. I tried many apps (King root, kingo root, muster root and like 100 app from play store and other websites ) to root but failed.

Then i try ADB and bootloader by Java on PC — still nothing. I also clean the charging port very carefully. By the way, fast charging is not working and takes a long time to complete charge — approximately 5 hours.  So finally i have a note 5 which takes 5 hour to charge and goes 8 hours battery backup. I can’t root it or connect to computer to resolve wakelock issue. Help me please. — Musa

Solution: Hi Musa. Overheating and battery drain problems can have a software or hardware cause. Thus, your first troubleshooting step is to identify which of these two is the true cause. As we’ve always mention in almost every post, if software troubleshooting won’t resolve the issue, a hardware problem may be to blame. Below are the things that you can try.

Wipe the cache partition. During the first boot up, just after you bought the phone, the system will create files for each app and service. These files will be stored in a certain directory only the system could access; the directory is called cache partition. Over time, some of the files get corrupted especially during updates. If the new system tries to use them, conflicts may occur. Hence, you need to delete the obsolete files so that the new system will create new ones but since you don’t have access to those files, you need to use the procedure that Android developers setup for you–wipe cache partition via Recovery Mode.

So, you need to boot the phone up in Recovery Mode first before you can wipe the cache partition. 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 ‘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. If refreshing the cache partition won’t fix the problem, your next step is to check if a third party app is the cause. This can be done by preventing third party apps from running via safe mode. You must restart your phone in a different environment called safe mode to do this. Here’s how:

  • 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 Vol 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.

Factory reset. Should the issue remains, the last step that you can try on your level is the more drastic solution of factory reset. Doing so will erase everything on your phone so make sure you create a back up of your personal data before you proceed. To perform a factory reset, kindly do the following 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 ‘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.

Seek phone repair or replacement. If the three procedures above won’t change anything, it’s time that you consider having your phone physically checked for possible hardware malfunction.

Problem #2: Galaxy Note 5 won’t boot normally after a repair

The phone’s GPS was working about 30 to 40% of the time. It was so frustrating, so I looked everywhere on YouTube to fix it. Finally, I found a YouTube video that shows that the antenna pins inside the phone needs to be bent up to get in contact with the antenna connectors in the middle housing. I opened my phone up successfully without any issues and managed to bend the pins. Thankfully, the process worked and my GPS is now working at full capacity again. However, the phone started freezing and randomly rebooting and even getting stuck on Odin screen with the message “couldn’t normally boot” and saying “Downloading, do not disconnect source”. I don’t know what I did wrong in there, but I really hope I didn’t mess up any hardware in my phone. Please help? — Ahmed

Solution: Hi Ahmed. Did the boot issue happen right after you opened the phone? If yes, then you only have yourself to blame. You may have damaged some components after the repair that causing them to send false signals to the system, preventing a complete boot up sequence. We’ve seen all sorts of issues following a botched repair but the thing is, there’s no way to know for sure what the existing problem is unless a full hardware diagnostics is done. And that is only possible if you have the right tools and training to do the job. Right now, we don’t even know where to start checking. We don’t know what your expectation is contacting us about your problem but we can’t, for obvious reason, know what’s wrong with your phone. If you don’t know how to perform a full systems check on this device, consider calling Samsung so they can attempt a repair. Keep in mind though that they may refuse to touch your device since it’s already been tampered with. In that case, bring the phone to a third party repair shop and let them do the checks.

Problem #3: Galaxy Note 5 not charging and not turning back on

Phone is stuck and won’t power on. Here’s what happened. I got home I knew my battery was probably at 3%. I fell asleep before I plugged it in. when I open my eyes I look towards my phone and happened to catch, I believe the boot logo, but in my head half asleep I said, “oh.” I caught my phone right when it was powering down so I got the charger and plugged it in quick. Then I realized that it kept going through the boot logo black screen boot logo a black screen just over and over and over. So I looked through some forums and I came across something that said to hold the volume down and power button and see if you can get it too boot normally or power down which I tried both.

I’m not an expert but I hit boot normally first and it just kept doing the same thing over and over. so I went through the power key volume down process again and clicked on power down and the screen turned black and didn’t flash the boot logo anymore. so I let it sit for a little bit, then plugged the charger in and instead of flashing the boot logo, now it’s flashing lightning bolt because the phone is dead. it vibrates, turns black, same thing that logo is doing except with the charge screen. What should I do? — Dawn

Solution: Hi Dawn. An important thing that you want to do first is to determine if your phone can boot up in any other mode. You can try safe mode, recovery mode, or Odin mode. Any of them may open a door towards eventual resolution. Of course, before you attempt to boot to any of these, you have to make sure that you leave the phone charged for at least 30 minutes. Alternatively, you can try booting to any of them while the phone is connected to a charger.

To boot your Note 5 in safe mode, follow the steps provided above.

Booting a Note 5 in Recovery or Odin mode is a bit similar. The only difference in booting each of them is the use of the Volume button. In order to boot in Recovery mode, you have to follow the steps below:

  • 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.

To boot in Download mode, follow the same exact steps as provided above but instead of pressing the Volume Up key, press the Volume Down button instead.

Now, each of these modes offers different options to help you. For example, if your phone only allows you to boot in Odin mode, then the only available step for you is to manually flash/install a firmware. If your phone only boots to recovery, then you might be lucky to fix the problem by doing a factory reset.

If your phone remains unresponsive though, don’t hesitate to call Samsung for a replacement.

Problem #4: FoxFi app not working properly on Galaxy Note 5

My Note is very off and we’ll go through the motions of activating the Wi-Fi or mobile hotspot and basically gets stuck. By stuck I mean it’ll show that it is working then when I close or back out of the Wi-Fi activation or hotspot activation, it’ll show that it never happened.

I am using FoxFi for the mobile hotspot because I have the unlimited data still and don’t want to pay 30 bucks for mobile hotspot through Verizon. you have to activate FoxFi to turn on Mobile Hotspot, then go into settings over to mobile hotspot itself. When activating mobile hotspot sometimes it’ll say checking subscription and then it’ll say “no subscription, please contact Verizon.” That’s only if I took too long to get over to the hotspot or it’ll say checking subscription. And then I will go away and it will act like it’s turning on a hotspot but never do it. The Wi-Fi has not been functioning for about a month-and-a-half. Sometimes if I do a soft reboot then it will work but not very often. I have not yet done a full factory reset as I don’t want to lose all my apps and I have to reinstall them but if I have to I will. — J

Solution: Hi J. Looks like the issue may only be isolated to the app you’re using to share your connection as a Wi-Fi hotspot. If your mobile data subscription is okay and there are no billing concerns that you need to settle first to keep it working, then you can leave it out as a possible cause. Your troubleshooting should focus on your phone.

The first thing that you want to do is to wipe FoxFi’s cache and data. Doing so will ensure that you bring the said app’s settings to default. Alternatively, you can simply re-install it and ensure that you have it updated. To delete an app’s cache and data, follow these steps:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Look for the app in question and tap it.
  • Tap Storage.
  • Tap Clear Cache and Clear Data buttons (in this order).

Should re-installation of the app, or the procedure above won’t help, contact the developer of FoxFi and let them know about the issue. The problem may be code-related, making them the only party that can fix it.

Problem #5: Galaxy Note 5 is not responding

-Phone was working fine but low on battery so I put it on the charger

-Came back and found the phone on and warm but screen was black

-Buttons seem responsive as the phone will appear to vibrate and the LED will flash occasionally but screen is completely black

-Tried holding down power button for long time and appeared to do nothing

-Tried holding volume button down and power button, appeared to do nothing.

-Tried holding power, volume up and home until device vibrated. then released power holding the other two buttons, but again nothing ever displayed on the screen

-After this last step, my LED is constantly on and the phone appears unresponsive. — Sean

Solution: Hi Sean. Like what we tell Dawn above, troubleshooting options for a user with a non-responsive phone is very limited. If you can’t boot the device in any other modes, then there’s really nothing much that you can do. Try to follow our suggestions for Dawn above and if nothing works, find a way to have the phone replaced.
