Problem #1: Getting SIM card locked error on Galaxy Note 5

I’m getting this alert that the SIM card has locked and to power cycle my device and if problem persists to contact customer service. So after I click on ok it just shows up on my notification bar as invalid SIM card. I’ve restarted it multiple times and I dialed ##72786# to do the factory reset and the problem is not going away. Please help me. — Jose

Solution: Hi Jose. A SIM card locked error has nothing to do with the phone but rather an issue on your account with your carrier. Troubleshooting your phone won’t get you anywhere. You must contact their customer service so they can give you another SIM card or do some account adjustments on their end.

Problem #2: Galaxy Note 5 keeps getting popups to install Power Sharing, Oculus apps

My Galaxy Note 5 just now started popping wanting to install Gearware and Oculus. I do not have either and it pops up at all the time interrupting what I am doing. Along with that it wants me to turn on something called Powershare. I said no and now fast charge does not work and it pops up every 15 minutes or so. I installed and now things are just as wonky. Power Saving pops up and asked to be turned on even though it is on, fast charge cannot be turned on, phone discharges at an incredible rate. I’ve done a cache wipe several times. — Robert

Solution: Hi Robert. We’ve encountered this issue with old Samsung devices before and at first we thought that it was because of a port malfunction, as was claimed by Samsung. We don’t think that’s the case though. It appears that the Power Sharing app from Samsung is creating a bug that results to charging issues. To go around the problem, the first thing that you should try is to uninstall Power Sharing app as well as Samsung Gear and Oculus apps.

If uninstalling them won’t fix the problem, head over to Application Manager and Force Stop the Samsung account and Samsung push service apps. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If nothing will change after doing the steps above, do a factory reset. Before you reset the phone, make sure that you create a backup of your files.

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. 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.
  6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  7. 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.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

After you reset the phone, try to avoid logging in to your Samsung account.

Problem #3: Galaxy Note 5 getting No service and not registered on network errors

NO service and not registered on network. Tried most of the options offered on blog however I cannot remove the battery from this phone. I don’t think this model allows it and when I try to go in and manually input my network it only pulls up Sprint AT&T and T-Mobile none of those which we are on anymore. — Lauren

Solution: Hi Lauren. These errors can be signs that your phone is not properly configured to work with your carrier’s network. It can also mean that you may have an account-related problem. If you have a SIM card, try inserting it to another compatible phone to see if it works. If it does, that’s proof that you phone is either not compatible with the network you’re trying to connect to, or that your account has issues that need to be addressed.  Make sure to contact your carrier’s technical support team for assistance.

Problem #4: Galaxy Note 5 can’t install a system update

I own a Samsung Galaxy Note 5 which is not able to update itself. It gives me an error of “failed to update device, contact nearest customer service.” I wanted to know whether we have any quick fix Because I’m always on the go and have little time to visit the service centers which are crowded.

Secondly, i don’t want to lose any of my data which is precious to me. Please help me. Thank you. — Omkar

Solution: Hi Omkar. We are assuming that you’re referring to over-the-air update here as you haven’t indicated otherwise. However, if you are having a problem with updating your phone manually (via Odin), that’s a slightly different issue that has a different set of possible solutions.

Now, you won’t be able to update your Galaxy Note 5 for one of the following reasons:

  1. there’s not enough storage space
  2. your phone is unable to reach the update server
  3. the update doesn’t complete due to server-side problems
  4. your carrier detects that your phone runs an unofficial firmware
  5. you have slow internet connection and downloading takes a very long time
  6. your phone runs custom recovery software

There’s not enough storage space. Make sure that your phone is ready to receive the  OTA update by making sure that there’s at least 2GB of internal storage space left. Recent OTA updates are usually just over the 1GB but you need the extra space for the cache later on. You can remove unused apps and transfer photos and other media to an SD card to free up some space.

Your phone is unable to reach the update server. This usually happens if your internet connection is unreliable, or that the update server itself keeps cutting out. If you are on mobile data, try to download the update using wifi instead and vice versa.

The update doesn’t complete due to server-side problems. Update files can sometimes take a long time to be completed because of slow internet connection or server issues. If the update keeps getting interrupted, make sure to narrow down the possible causes first. The first thing that you want to check is the reliability of your internet connection. Consider using wifi if your mobile data is slow or intermittent.

If your connection is okay or fast and doesn’t cut out, it’s possible that the problem is server-related. Try to restart your device and restart the download. If that won’t work, let your carrier know about it.

Your carrier detects that your phone runs an unofficial firmware. Installing an official firmware update over a custom firmware running on a device can brick a device so carriers often do some checks before uploading update files to a device. If the phone is detected to be running a different firmware, the system may stop the file upload to prevent bricking a device.

Your phone runs custom recovery software. If your phone uses custom firmware, it’s very likely that it’s also using an unofficial recovery software, which mostly prevents installation of OTA updates. To fix the problem, try to flash a stock recovery software first before attempting an OTA update.

If you’ve already considered all the items above but your phone continues to fail to install an update, contact your carrier’s customer service or send the phone in.

Create a backup

It’s your responsibility to create a backup of your important files all the time. Phones or storage devices can fail anytime. Be sure to back irreplaceable data up before attempting any update, or before you perform any software changes like an update installation. If you lose files after installing an update, you only have yourself to blame.

Problem #5: Galaxy Note 5 battery drain problem

Had sent to Samsung Service Center 4 times in a month to fix my battery draining super fast. Samsung changed battery twice but still the same. I am about to put this Note 5 in cold storage and use back my Note 3 (which is a hunk), a real great phone. I had tried factory reset few times and running without any apps loading….but still the same. I look forward your recommendation before this become a white elephant ! Thank you. — Simon

Solution: Hi Simon. If factory reset didn’t change anything and the phone has been sent several times to Samsung, that’s a clear indication that hardware is to blame. Don’t waste your time doing any software tweaks. Simply send the phone back in and this time, make sure to demand a replacement.

Problem #6: Galaxy Note 5 keeps freezing, losing battery power fast

I’ve 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. — Writeback

Solution: Hi Writeback. The number of apps installed on your phone can affect how fast your phone’s battery drain. The more apps you install, the more background apps and services are running all the time. Try to drastically cut the number of apps on the phone and observe it for a few days. Uninstall apps you haven’t used in the last 2 weeks. Chances are, you don’t need them and removing them can affect battery consumption.

Another good thing to do in this case is to try running the phone to safe mode to see if a third party app is to blame. Safe mode blocks third party apps and services so if one of the apps is to blame, battery consumption would be back to normal if you boot the phone to safe mode. Here’s how to do that:

  1. Turn off the phone completely.
  2. Press and hold the Power key.
  3. Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  4. The phone will restart but keep the Volume Down button pressed.
  5. Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  6. You may now release the Volume Down button.
  7. Observe the phone for a few days while it’s on safe mode

Sometimes, installing app and/or system updates can fix battery-related issues. Make sure that all your apps are updated and that you install any pending system updates.

You can also check the Battery monitoring tool under Settings to see what apps are consuming battery power the most. If you notice that an app keeps topping the list, you can try to optimize it or simply uninstall it to lessen the pressure on the battery.

Battery drain problem and freezing issues can also be signs of a bad battery or logic board issue so if the problem remains after doing all the steps above or even another round of factory reset, you must consider a phone replacement.
