Today’s Problem: Galaxy Note8 sensors (Iris scaner, auto-rotation, heartbeat sensor, GPS, etc) stopped working after Oreo update

My Note8 sensors like iris scanner , auto rotation, heart beat sensor, running, stress and screen mirroring etching aren’t working. Even I tried your tips but it didn’t work. Eventually this problem came after new Android update 8.0 . Please give me solution as soon possible. Thank you for time. — Omesh kumar

Hello, I’m from Bangladesh, my Note 8 sensors are not working. It happens few days after updating oreo security patch april 01 2018. At first my iris scanner was not functioning properly and it showed “iris scanner is not responding now, please try again later”. Biomatrics are not working! Then it starts restarting automatically several times in a day. From last few days auto restart problem has gone. Auto rotation is not working. Another big problem, while talking time display is not going off in other hand pannel and notification setting pannel comes open and making so many problem. For that bluetooth is almost every time starts scaning and call connection also going to be lost by the contact between my ear and red colour phone symbol. I’ve tried to fix those issues by soft resetting, factory resetting without any backup file, even wipe catches partition, from settings to apps permission then default and restarted, from apps cache file also cleared from storage and also safe mode too but no any responses at all!!! Why samsung is not giving us solution? Most of the peoples who bought note 8 are getting pieced off and also saying that why we didn’t took Iphone X ??? At this point what can i do, could you tell me please! I mean is there any solution maker is there? I’m working in Nuclear power plant as a Medical Coordinator for 24/7, for 1 month then 1 month off then again 1 month duty and not permitted to go outside! I need few more days to stay here. So, it is not possible for me to go any samsung service center! I also did software downgrading and with samsung official software only but no any improvement! 2 days later again updated to oreo but still same result. Please help me……….. Thank You. Regards. —  Dr. Md Wahiduzzaman

Solution: If these sensors were working before you installed an Oreo update, you should consider doing these four possible solutions:

  • cache partition wipe
  • app and Android updates
  • check for bad third party apps
  • factory reset

Refresh the system cache

This is one of the first troubleshooting step that one can do when a device encounters problems after an update. Sometimes, updates may corrupt the system cache, which in turn, leads to all sorts of problems. To check if your Note8 has a system cache issue, you should consider wiping the cache partition with these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Keep apps up-to-date

One of the best way to maintain Android’s health in good condition is to ensure that all apps are compatible and updated. Apps don’t work in isolation and they can sometimes cause problems problems with Android or other apps if they become incompatible after an operating system update. If you are adventurous with apps, you should make it a point of making sure that everything that you add to the system is optimized. Some old apps, while can still be installed, may not work properly with new Android versions, or may still need some patching up from their developers. Always keep your apps updated by checking the Play Store. Here’s how:

  1. Open Play Store app.
  2. Tap More settings at the upper right.
  3. Tap My apps & games.
  4. Tap UPDATE ALL button if you have multiple updates.

If you set Play Store to automatically update apps for you, then simply skip this suggestion.

Not all apps can be installed from the Play Store so if you have some from other sources (through APK sideloading), make sure that those apps are fully compatible with the current Android version on your device. Talk to their developers if you’re not sure.

Observe in safe mode

Your Note8’s sensors should work properly all the time. However, they may encounter problems if one of the installed apps is incompatible or may be interfering with Android. To check, try to boot your Note8 to safe mode and see what happens.

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
  7. Let your phone run and check if the sensors work normally. If they do, that means one of your apps is to blame.

To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note8 is still problematic, repeat steps 1-4.
  6. Keep doing the same cycle until you’ve identified the culprit.

Reset all settings to defaults

Should the issue remain, or if there’s no change when your device is on safe mode, factory reset might help. Before wiping the phone, be sure to back your data up to avoid losing them.

To factory reset your Note8:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Reflash previous android version

Update-related issues are sometimes fixed by rolling back the Android version on your phone. The process involves flashing the previous stock Samsung firmware to your Note8 so be sure to do some Google research on how it’s done. This may or may not work depending on what’s causing the issue in the first place. This is a desperate shot though so there’s also a big chance that it may not work, just like what Dr. Md Wahiduzzaman has experienced.

Report the bug to Samsung

For those Note8 owners who are experiencing this problem despite having done all the software solutions above, we strongly suggest that you take your device to your local Samsung dealerships so a ticket can be created for these cases. We are still in the process of gathering information whether or not this issue is isolated to a few devices, or if it’s widespread. So far, we’ve only receive reports about it from some users in Asia. We will update this troubleshooting article once we get word from Samsung, or if we find an effective solution for it.

How to fix a Galaxy Note8 non-working sensors: screen rotation, heartbeat, other sensors not working after an update

Hello and welcome! Today’s troubleshooting article is our response to issues reported by three #GalaxyNote8 users. If you have your own issues after you upgraded Android, this post might help.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix a Galaxy Note8 non-working sensors: screen rotation, heartbeat, other sensors not working after an update

I buy a new note 8 recently i update this and the sensors is crazy, not working. heart good no capture image with heart sensor no screen rotation and more, basically i have a nokia with good system and camera this is very sad because now i thinking maybe i lose 1k of my money for trust on samsung. i use the code *#0*# all values on sensor test is on 0 no work nothing. i don’t know what i can do for solve this. i don’t know if is the phone is damaged or if is tje system update i hope no have the first problem and can solve this in possible update.

Solution: There’s been sporadic reports from some users for months now about the same exact issue you’re experiencing so this must be a hardware issue. A quick Google search and you’ll notice that other users also report their Note8 sensors stopping. Unfortunately, there’s no official word from Samsung whether this problem only affects a certain batch of Note8s, or if a widespread breakdown.

We don’t think there’s anything that a user can do to fix the issue but we’ll continue to suggest that you do the usual stuff. To troubleshoot the problem on your end, follow our suggestions below.

Check for bad third party app

We’re not aware of any particular third party app that stops sensors in a Galaxy Note8 but checking for one is worth it. To see if one of your apps is preventing the sensors from doing their job, we suggest that you restart the phone to safe mode. In this mode, all of your apps will be suspended and only preinstalled ones will be allowed. If one of your added apps is to blame, safe mode should help in this situation. What you want to do is to restart your Note8 to safe mode then check for the problem.

Here are the steps to restart your device to Safe Mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Check for the problem.

Once the phone has been set to safe mode, run the phone and see if sensors are working. If everything looks good, you have an app issue. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note8 is still problematic, repeat steps 1-4.

Reset all settings

Should nothing change even when device is booted to safe mode, the next step is to restart the phone and try to reset all its settings. This will return all user customizations back to stock. If a bug developed and affects phone settings, doing this troubleshooting step may help.

Below are the steps to reset all settings.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Factory reset

An important troubleshooting step. By wiping the phone and returning its software to defaults, we’ll know if the issue is due to an operating system bug or not. If you have important data that you can’t afford to lose, be sure that they’re copied somewhere.

Once ready, do the steps below to master reset your phone:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Flash stock firmware

If you attempted to root the device or install an unofficial firmware to it, there may be a firmware coding issue that bricked the device. Make sure to reverse whatever you did and return Android to its previous, known working version.

Warranty option

If all the steps above fail to resolve the problem, you should contact your local Samsung dealer so they can check the hardware and advise you whether they can fix it, or if they need to send a replacement. Avoid tampering with the software and hardware at this point so as not to cancel the device’s warranty.

Problem #2: Galaxy Note8 not getting notifications after an update

Samsung Note8. An update occurred a few weeks ago and since then I do not receive notifications of text messages. I do not hear the sound or get the little blurb icon at the top of my phone. Also, beginning after this same update, I hear my text notification sound but it’s not for a text. It’s telling me an app is overpowering my system so I close whatever app it says. I also get notifications using this sound such as from a retailer who has an app on my phone such as Joann Fabrics to tell me about a sale. Slowly but surely I started turning off notifications. Yet some still happen so I’m uninstalling the apps. Until this update, none of these things have been an issue.

Solution: If you are positive that the problem started after a software update, there may be a problem with the system cache. As your first troubleshooting step, you want to clear the cache partition. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Once you’ve cleared the system cache, you then want to make sure that you set all notifications for whatever app properly. To do that, go under Settings > Notifications and ensure that you enable notifications for a selected app.

If you are using a personalization app like Zedge, try erasing from the system and see if that will change anything. Some personalization apps can override default notification settings or interfere with Android so this is worth checking. If you are not sure whether or not you have such app, or if you want to check if a third party app is responsible, try restarting the device to safe mode. Check out our suggestions in Problem #1 on how to use safe mode to identify a bad app.

You can also try to delete the data of BadgeProvider app and see what happens. BadgeProvider app is a core Android app that manages incoming notifications of apps. Sometimes, if this app is glitchy, it can cause problems like the one you’re experiencing. To return it to its factory defaults, follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your Note8 and check for the problem.

Problem #3: How to fix Galaxy Note8 not recognizing SD card issue: SD card not detected after an update

I have a 64GB San Disk micro SD card in my Samsung Note8. I have never had any issues with it until a few weeks ago when it suddenly stopped being recognized by the phone at all. I did not remove the card from the phone or even open the card slot for over a year before this issue started. So I really doubt that the slot is dirty. The memory card is recognized and contains all the files still when I insert it into a PC (I have backed it up) but the PC was “unable to complete” formatting of the card. Any thoughts as to what’s going on here? My phone did recently do a system update.

Solution: Firstly, you want to make sure that you back all contents or anything important up from the SD card to your computer to avoid losing them.

Secondly, we can’t really tell what caused your phone from failing to read the SD card following a software update. Android is a complicated software environment so anything can happen. There may had been some coding changes to how your Note8 reads SD cards. If you want to know whether the issue lies on the phone or on the SD card, you can do a process of elimination. To do that, you want to start with the card itself. Try to reformat it using your phone and see if it works. If you can’t do that, or if the device still won’t recognize it, then you should move to the phone option by returning it to its factory settings. Check out the steps above on how to master reset your phone.

How to fix a Galaxy Note8 that has bad sensors after installing an update

Hello Android fans! Today’s troubleshooting article answers a possible emerging issue for the #GalaxyNote8 — sensors not working after an update. We’re still at the early stages of our investigation for this issue but so far, it seems that the problem only affects Note8 devices in a certain region. Continue reading on if you encounter the same trouble as well.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

 

Problem #1: How to fix a Galaxy Note8 that has bad sensors after installing an update

My Galaxy Note 8 CSC: XTC (Philippines) made in Vietnam start error on Iris scanner and all sensor is not work anymore because software update that samsung issue. have been tried all your suggestion on this sites but none of those works. I went to samsung service center, they said it must be the motherboard issues and need to be replaced. but it so nonsense since on the previous software its working perfectly.  the motherboard replacement cost arround $400 which is so expensive. my device is currently out of warranty and its to bad.

Solution: We’ve been getting more and more Note8 users sharing the same experience as yours so this must be a coding issue. We’ve already contacted Samsung about the issue but they haven’t answered our query yet. We think they’re still trying to gather as much information as we are at this time so there’s no official solution for this problem. Based on our own initial investigation, majority of cases are units in Asia and the Middle East. This may be a carrier-specific issue, just like in some Samsung Galaxy issues in the past. There’s also a chance that this problem may only be affecting a particular batch of Galaxy devices.

Factory reset

At this time, there’s no effective way to fix this bug yet so we are left with trying all possible solutions.

In many cases, factory reset is useless but if you haven’t tried it yet, we suggest that you do it right away. Here are the steps to do that:

  1. Create a backup of your data.
  2. Turn off the device. This is important. You won’t be able to reach Recovery Mode if the device is not powered off.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Reflash the stock firmware

We have not received any feedback from Note8 users who may have successfully fixed the issue thru flashing but we’ll continue to recommend it in this case, especially since Samsung is taking a convenient route by suggesting a motherboard replacement. By flashing your phone’s firmware back to its known working version, we hope that you’ll be able to fix the problem.

Flashing is basically a procedure that allows an Android user to manually install Android to his or her phone. This procedure is not recommended by Samsung due to risks involved. Flashing your device incorrectly can damage its software for good so you want to be careful when doing it. Flashing guides for phone models can vary slightly so be sure to do research before doing it. Before using a particular flashing guide for your phone model, be sure to check if a lot of people has tried it and if they encountered errors when following it. If many of them have problems with the guide, that’s probably because it’s fake or erroneous.

Also, make sure to use the correct firmware version for your device. Not doing so is the easiest way to brick your Note8. A good flashing guide should tell you the required tools and files to use.

Problem #2: Galaxy Note8 Photo app keeps popping up after an update, won’t transfer files to computer

Recently, there was an update for my phone and I had to wait a few weeks to get to Wi-Fi to download it. Usually that isn’t an issue, but after my phone updated, I started to notice a number of odd things. My photo app kept popping up a window to say it had stopped working, even when I hadn’t accessed it. That soon resolved into just when I clicked onto a picture or opened my gallery but I didn’t notice any problems until I tried to share a picture through my Facebook app and it completely doesn’t recognize pictures from anywhere. Today, I decided to try and put them onto my computer and now my MTP application says that it has stopped and I can’t even transfer files from my phone to my computer anymore.

Solution: If you’re positive that the issue started right after installing an update, these are the possible solutions that you can do.

Wipe the cache partition

Updates can sometimes corrupt the system cache resulting to all sorts of issues. To ensure that your Note8 has fresh system cache, try clearing the cache partition with these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Install app updates

The next good thing to do in this case is to ensure that all of your apps are updated. Installing a system update does not necessarily mean apps are updated too. Sometimes, incompatibility issues can surface after Android is updated to a more recent version. To lessen the chances of that from happening, make sure that apps are compatible with your operating system as well. To check for app updates via Play Store:

  1. Open Play Store app.
  2. Tap More settings at the upper left (three-line icon).
  3. Select My apps & games and update your apps.

If you have apps installed outside of the Play Store, make sure that they are compatible with Android Oreo. If you are not sure, contact their developers.

Check for possible bad third party app

One of your installed apps may be behind this trouble. To check, you want to restart your Note8 to safe mode. When on safe mode, your phone will not allow third party apps to run. So, if your device works properly on safe mode but not in normal mode, that’s a clear sign that one of the third party apps is causing the problem.

To boot your Note8 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Observe the phone for a few hours and see if the problems remain.

To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note8 is still problematic, repeat steps 1-4.

Use Smart Switch

In case there’s a problem with your computer’s drivers, you can also try to use Samsung Smart Switch to transfer your files. It is an official application built by Samsung and it works seamlessly with both Windows and Macs. Visit this page for steps on how to install Smart Switch to your computer.

Factory reset

Finally, don’t hesitate to factory reset your phone should all our solutions fail. Refer to the steps above on how to factory reset your Note8.
