Troubleshooting your Galaxy Note 5 that keeps freezing

Problem: Hey guys! I have a problem with my Galaxy Note 5. It’s just a couple of months with me and has never been abused; it hasn’t touched water and never fell. As of late, it started freezing regardless of what I’m doing. When it does, I can’t do anything because the phone is unresponsive so I would just have to wait for it to become responsive again. I know how to use my phone, I’m not just as savvy as you guys. Besides, I fear that if I did something, I might mess it up all the more. So, I need your guidance; a step-by-step guide would be so helpful. Thanks in advance! — Karen

Troubleshooting: Hello Karen! Random freezes happen all the time even to powerful smartphones like your Note 5. The device has the muscle to give you superb experience while using it but then you have to consider everything that runs in it needs to use RAM and other resources not to mention that some apps and services are glitchy. That’s the reason why we need to update them as soon as developers roll out updates. The same goes for the firmware. With all that being said, let’s go to our troubleshooting. Please follow the steps below…

Step 1: Make sure it’s not just a minor system glitch

Glitches on both the firmware and hardware happen all the time and more often than not, they’re minor issues and for those, all you gotta do is reboot your phone.

It’s the safest and simplest troubleshooting procedure you can do but it may fix the problem. However, after the phone freezes and it refused to respond to the typical reboot process, you have to do the forced reboot procedure: press and hold the Volume Down and Power keys together for 10 to 15 seconds and the phone should reboot provided there’s enough battery to power it up.

Step 2: Find out if the problem is caused by apps

Assuming the phone turns on normally after the force reboot but the freezing still remains, then let’s go after the apps. At this point, we don’t know for sure what the cause is but let’s try to isolate the problem immediately by booting the device in safe mode. Just before I give you the steps on how to restart your Note 5 into safe mode, let me explain briefly why you have to do this.

Apps are grouped into two general categories–pre-installed and third-party. Pre-installed apps are already in your phone when you got it while the third-party ones are those you downloaded or installed. When in safe mode, all third-party apps will be temporarily disabled leaving pre-installed the only ones running. So, if the problem is caused by one or some of your downloaded apps, the freezes won’t occur when in safe mode, otherwise, you have to find apps you installed that are causing the problem and uninstall them. Now, here’s how you boot your device into the Safe Mode:

  1. Press and hold the Power key.
  2. When ‘Samsung Galaxy Note 5’ appears, immediately release the Power key and then press and hold the Volume Down button.
  3. Continue holding the Volume Down button until the phone finishes the restart.
  4. When you see Safe Mode on the lower left corner of the screen, release the button.  

When the phone is in this state, closely observe how it performs and whether or not the freezes still occur because if so, then we might be looking at a possible firmware issue.

Step 3: Try deleting the system cache especially after a firmware update

Corrupt system caches may also cause this kind of problem and it often occurs after a firmware update. But regardless whether you just updated your Note 5 or not, it’s imperative you do this procedure before you decide to do the reset.

System caches are temporary files created by the system for better performance and to make apps open quicker and smoother. However, during updates, these files get corrupted but the system still continues to use them. In this case, the performance of the phone will be the first one to suffer. The good thing is that caches can be deleted without adverse effects. In fact, it’s even better to delete them from time to time. Here’s how you do it.

  1. Turn off your Galaxy Note 5.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Should the problem persist after the procedure, you have no other choice but to reset your phone.

Step 4: Perform Master Reset on your Galaxy Note 5

This is your last resort. If the problem continues after this, then it’s a sign that the phone is suffering from a minor hardware issue and needs to be checked by a technician. It could also be just an issue with the firmware but it needs to be reinstalled to work properly and doing so on your own will void the warranty so you still need a technician. That being said, follow the steps below and see if the problem gets fixed or you need to send it in for repair.

Before the reset, make sure you backup all your files and data that are saved in your phone’s internal storage as they will be deleted during the process.

  1. Remove your Google account and disengage the screen locks to make sure you won’t trip the Factory Reset Protection (FRP).
  2. Turn off your Samsung Galaxy Note 5.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Troubleshooting your Galaxy Note 5 that slowed down considerably

Problem: One of the reasons why I bought the Note 5 is because I happened to use my brother’s for a couple of days and was amazed at how fast and responsive it was. Long story short, I bought mine but after just a few months, the performance deteriorated. Now, when I open some apps, it will take forever for those apps to open. The same thing happens when I open the Settings menu, it just takes too long to do anything. What can I do to bring my phone back the way it was before? — Jean

Troubleshooting: Hi Jean, the problem you have with your Galaxy S5 is very common to Samsung users. We already received complaints about this issue and we’re able to check what’s the reason why it’s happening. This issue can be given solutions here, just check out and follow the tips that we will provide you. But prior to proceeding to the troubleshooting steps, let’s check if your Samsung Galaxy Note 5 have undergone Marshmallow update. If yes, you’ve undergone with the update. Let’s try to wipe the cache partition. To do this all you need to do is to follow the steps I provided above (step 3).

You may try to update to a newer version of Marshmallow.

  1. Go to Settings.
  2. Choose About Phone.
  3. Software Information.
  4. And check if the latest OS updates is available for your Note 5. If there is an available update, then download it.

If nothing happens, it would be good to manage memory storage to verify if this is the cause of the issue. And if you’re already near full memory, try to delete the unnecessary files or you may try to move those files to cloud-based storage that you can access by the use of internet, transfer files to computer. If it won’t work, try to perform a factory reset.

Remember that a master reset will restore your phone to factory defaults. Meaning you will lose all your personal data stored on the internal memory, this may include contacts, photos, videos, recordings and downloaded apps. So it would be wiser to backup important files before you start performing the reset. And here’s how to do this;

  1. Tap the Apps icon from the Home Screen.
  2. Select Settings.
  3. Choose Backup and reset under User and Backup.
  4. Check the tick boxes next to Automatic restore and Backup my data, as you hope.
  5. Tap Factory Data Reset.
  6. Tap Reset Device.
  7. If prompted, enter your password or PIN and tap Continue.
  8. To complete the process, tap Delete All.

And if you haven’t undergone any OS update but still it is taking you forever to execute commands or even go to settings, let’s try to check and close apps (force stop) running in the background. Since these applications are currently active on your device, this may cause the slow speed that you are experiencing, so it would be a very good idea to stop and even uninstall [or close the] unnecessary apps that you are not going to use and here’s how to do that.

  1. Tap Apps from the Home Screen.
  2. Go to Settings.
  3. Proceed to Applications.
  4. Tap Application Manager.
  5. Swipe the Downloaded screen.
  6. Just select the app that you want to remove or uninstall.
  7. Now, select Uninstall.
  8. And finally, tap OK to confirm.

After performing those things, we recommend you perform a soft reset, or reboot your phone after forcing the closing of apps running in the background. It often helps resolve several issues and this includes slow, freezing, and unresponsive device.

  1. ive been trying to figure out my Note 5 problem for a few months now. I cleared the cache files…even did a factory reset…went into safe mode…but still my phone freezes. Some times it will go months perfectly fine (maybe a freeze here or there) but there are days when the phone will freeze every 1-3 minutes for the entire day and it drains my battery in the process. For some odd reason, it tends to last longer if I plug in my earphones and play music.
    My thoughts: 1)My phone was manufactured in Singapore or Hong Kong (I forgot) but am currently using it in South Korea. I don’t see how this could be a problem but could be something conflicting.
    2) I just bought a crappy phone and just had bad luck
