How to fix Galaxy Tab S4 “Not Registered On Network” error

This troubleshooting article gives you the details in fixing “Not Registered On Network” error on Galaxy Tab S4. If you are one of the unfortunate users to have this problem, don’t worry as the solutions are usually within your grasp.

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.

“Not Registered On Network” is one of the common errors that can occur on any smartphone. If your Galaxy tablet is unable to connect to mobile data because of this error, or if it’s having a hard time using any of its network functions because of this bug, learn what you can do below.

Simulate a “battery pull.” Restarting the system should be the first thing to do in this case. Many temporary network bugs are fixed by doing this simple step. If you haven’t tried doing this yet, here’s what you must do:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

This procedure simulates the effects of physically disconnecting the battery. Your device has a non-removable battery pack so this is the alternative to the old way of restarting a frozen or erratic device. This also works at times for many network issues so hopefully this helps. If nothing changes though, proceed to the next steps below.

Check for on-going network issue. If “Not Registered On Network” error happens all of a sudden, it’s possible that it may be the result of a service disruption. If you have other phones on the same network, try to see if they also show a similar error. If multiple phones are unable to connect to your network, what you can do is to simply wait for the problem to be fixed. In some cases, a carrier may intentionally disable their cellular services to comply with security requests from the government. In other cases, an unexpected outage may be to blame. As an end user, there’s nothing much that you can do about that.

Reset network settings. At other times, “Not Registered On Network” bug can be due to a device network settings not properly configured. To ensure that your Galaxy Tablet has all the correct settings, try resetting its network settings with these steps:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your S8 and check for the problem.

Check SIM card. Sometimes, “Not Registered On Network” bug can also be caused by a fault in a SIM card. To check, you can either insert another working SIM card from your carrier, or you can insert your SIM in another compatible phone. Either way should help you check the health of the card, or whether it’s functional or not. Make sure to do the following:

  1. Turn off your phone.
  2. Remove the SIM card carefully.
  3. Wait for at least 10 seconds before turning the phone back on.
  4. Then, re-insert the SIM card and check for the problem.

Observe on Safe Mode. Another possible reason for this error is a bad app. Some poorly coded app may be interfering with Android or its functions. To see if network settings is affected by a third party app, run the phone to safe mode. In Safe Mode, no third party apps will be allowed to run. So, if there’s no “Not Registered On Network” error while your Note9 is on safe mode, that’s a sign that a bad app must be the cause. Here’s how to restart your phone 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.

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 device is still problematic, repeat steps 1-4.

Reset app preferences. In some cases, apps may encounter problems if one or a number of default or core system apps and services are disabled. To ensure that all your apps have access to defaults apps, do the steps below:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S9 and check for the problem.

Factory reset. Should nothing change at this time, consider wiping the phone to return all software settings to their defaults. Make sure to back your personal data up ahead of time. Follow the steps below to factory 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.

Contact network operator. This is the final troubleshooting step for you. Not all network troubles is device-related. A fairly good number of them also comes from carrier or network side. Be sure to report the problem to them if none of the things we suggest in this post help.

How to fix Galaxy Tab S4 slow wifi issue

Dealing with slow wifi is one of the most frustrating issues to fix. In this troubleshooting article, we show you the ways to fix slow wifi problem on Galaxy Tab S4.

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.

How to fix Galaxy Tab S4 slow wifi issue

Below are the troubleshooting steps to do to fix your Galaxy Tab S4 slow wifi issue

Restart the device. This is one of the basic troubleshooting steps that you need to do in this case. Sometimes, wifi problems are due to temporary bugs. To fix these types of bugs, all you need to do is to clear the RAM and refresh the system in general. To do that, follow these steps:

  1. Press and hold the volume down button and don’t release it.
  2. Then, press and hold the power key while holding down the volume button.
  3. Keep both keys held down for 10 seconds or more.
  4. Let the phone restart.
  5. Check for the problem.

Confirm wifi is working and not slow. Should restarting your S8 won’t work, the next troubleshooting step is to check whether or not you have a slow internet connection problem, or if the issue lies on the phone itself. To do that, you want to conduct a speed connection check. If you don’t have an app Speedtest by Ookla installed to check your internet  speed, you need to get one from the Play Store first. Then, once you have it, run a speed test three times. If the test results are more or less the same and they are way too low for your subscribed speed, that means there’s a problem with your router or Internet Service Provider side. On the other hand, if the speed test results are good, that is, it is within acceptable speed as far as your internet subscription plan is concerned, then you may have an issue with your phone. To fix it, continue with our suggested solutions below.

Another way to check if the issue lies on the router or your ISP is to check with other devices. If they also get slow connection problems when using your wifi, that’s a tell tale sign of an issue with your router or ISP side.

Ensure device is not downloading or streaming. If you noticed that the general performance of your wifi network is slow, it’s possible that your tablet or any other connected devices may be hogging the bandwidth. If you are on a limited broadband subscription speed and there are multiple devices downloading or streaming videos at the same time, the overall network speed may suffer. Make sure to turn off all devices that uses your wifi and see if that will make a difference.

Forget wifi connection. Another basic thing to do here is to disconnect the device from your wifi network. Doing so refreshes the connection and potentially clears up any bug that may have developed with the current wifi setup. It may help as it disconnects the device from the router and forces a new connection later on. To forget from a wifi network:

  1. Pull down the status bar from the top.
  2. Press and hold on wifi.
  3. Press and hold on the wifi network you’re connected to right now.
  4. Select Forget network.

Reboot your networking device. Aside from refreshing your Galaxy Tab S4, it’s also necessary in this situation to refresh your network devices such as modem/router, wifi signal booster(if you’re using it), etc. Essentially, the goal is to restart everything. Most of today’s Internet Service Providers or ISPs no longer provide a modem and a router but if you still have both, make sure that do a sequential powercycle. Here’s how to do that:

  1. Turn off the modem.
  2. Turn off the router.
  3. Turn off devices affected by slow connection issue.
  4. Wait for at least 30 seconds.
  5. Afterwards, turn the modem first and wait until it has fully initialized.
  6. Then, turn the router back on and wait until it too has full initialized.
  7. Finally, restart the affected gadgets and see if the connection speed has improved.

If you are only using a router, then simply ignore the step with the modem.

Use static IP. By default, your Galaxy Tab S4 should use dynamic IP or DHCP when connecting to a wifi network. To see if there’s a router bug that may be blocking this feature from working normally, you can switch to static IP instead. This troubleshooting step presumes that you know how to configure and play around with your router configuration. If you have no idea how to configure your router, then simply ignore this step.

If you want to give static IP a try though, here’s how to do it:

  1. Pull down the status bar from the top.
  2. Press and hold on wifi.
  3. Press and hold on the wifi network you’re connected to right now.
  4. Select Manage network settings.
  5. Make sure that Show advanced options is checked.
  6. Under IP settings, select Static.
  7. Once you’ve done that, other fields below will become available so you can configure them. These fields include the IP address, Gateway, Network prefix length, DNS 1, and DNS 2.
  8. Make sure to enter a valid IP address and Gateway IP.

Use third party DNS. In order to connect to the web, there’s a chain of connected devices that must work. Even if your home networking devices and phone are working, it’s possible that there’s another point in your connectivity setup that may not be working. For example, it’s not unheard of sometimes that your carrier’s Domain Name Server or DNS may go down. It’s a type of server that converts the URL you’re typing in the address bar into IP addresses that computers in the web can understand. For example, if you type in Google.com in the address bar, this is not really understandable for computers or servers. It’s the job of DNS to convert the letters into an IP address so that your request will be interpreted as wanting to reach Google.com website. At times, the DNS your ISP uses may encounter an issue causing slow browsing issue. To check if you have a DNS problem, you can try to change the DNS 1 and DNS 2 of your device’s wifi settings, just like when you change from DHCP to static.

To change the DNS servers:

  1. Pull down the status bar from the top.
  2. Press and hold on wifi.
  3. Press and hold on the wifi network you’re connected to right now.
  4. Select Manage network settings.
  5. Make sure that Show advanced options is checked.
  6. Under IP settings, select Static.
  7. Once you’ve done that, other fields below will become available so you can configure them. These fields include the IP address, Gateway, Network prefix length, DNS 1, and DNS 2.
  8. Enter the new DNS servers you want. We suggest that you use Google’s own DNS servers as they more reliable and faster than any other DNS servers out there. For DNS 1, enter 8.8.8.8 while for DNS 2, use 8.8.4.4.

Refresh network configuration. To ensure that all network settings are correct, be sure to also reset network settings on your Galaxy Tab S4. Here’s how to do that:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap RESET SETTINGS button.
  6. Restart your S8 and check for the problem.

Clear cache partition. Some network problems may be caused by bad system cache. To keep your tablet’s cache partition in top shape, make sure to clear the cache partition. Here’s how to do that:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby (Home) 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.

Check wifi on Safe Mode. There may be a third party app causing the problem. To check, boot the phone to safe mode and check how wifi performs. To restart 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.

Remember, safe mode blocks third party apps. If wifi improves significantly while your Galaxy Tab S4 is on safe mode, that means that one of your downloaded apps is hogging the bandwidth. It be a legit app or malware. If you have no idea what that app might be, you can use the process of elimination to identify it. Here’s how to do that:

  1. Boot to safe mode.
  2. Check for the problem. If wifi is not slow at all, proceed to the next steps below.
  3. Uninstall an app. Start with the most recent ones you installed or updated.
  4. After uninstalling an app, restart the phone to normal mode.
  5. Check for the problem. If the issue remains, repeat steps 1-4.

Factory reset. If nothing has worked so far, the last troubleshooting step that you can do on your device is factory reset. If it’s a software bug or an app that’s causing the problem, factory reset should help.

  1. Create a backup of your personal 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.

Check router. If factory reset fails to resolve your wifi issue at this point, you can also try to check your router. There are a number of possible reasons that might affect the speed of your router. If you can, try to factory reset the router before calling your ISP.

Get help from ISP. If you can’t still resolve the issue at this time, especially if you are positive that it’s router problem, the most ideal thing to do is to contact your ISP. Unless you purchased your own router separately, you should let your ISP handle the router troubleshooting to prevent causing more issues.

How to fix Galaxy Tab S4 won’t charge issue

Hello Android fans! This post will tell you what to do if your Galaxy Tab S4 has decided to stop charging for some reason.

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.

How to troubleshoot a Galaxy Tab S4 that won’t charge

If your Galaxy Tab S4 has stopped charging, there may be an app, software bug, or hardware malfunction causing it. To fix the problem, follow our suggestions below.

Forced reboot

Sometimes, Android may fail to load normally due to a temporary bug. To see if the bug can easily be fixed by refreshing the system, you can simulate the effect of disconnecting the battery. Here’s how that’s done:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Use another set of charging accessories

If your Galaxy Tab S4 was previously charging normally but then stopped, there may be an issue with the charging cable or adapter or both. Tiny wires inside the charging cable can break if you’re not careful. This is the usual reason why a USB cable stops working. If possible, try getting an official Samsung cable and adapter and see if that will fix the problem.

Alternatively, you can borrow a new set from someone else, or visit your local Samsung retailer to charge.

Check the port

If you’re positive that you’re using a known, working cable and adapter, the next good thing to do is to check if there’s any visible defect on the charging port. Your Galaxy Tab S4 may stop charging be due to a a number of things:

  • corrosion can set in if you previously exposed your phone to seawater or any other liquid apart from fresh water.
  • careless usage may also damage the port if you don’t properly handle your phone while charging.
  • using unofficial charging accessories may damage the charging system due to incompatibility.
  • presence of dirt or foreign objects in the charging port may jam it or prevent the charging cable from working properly while charging.

If you think the port is dirty or has debris or lint inside, try to use a can of compressed air to blow them out. Avoid sticking anything in the port to minimize the chance of causing permanent hardware damage.

Check for moisture

While your Galaxy Tab S4 can survive occasional splashes and rain, it may not allow you to charge at all if the charging port is wet, or if there’s presence of moisture inside.If your device is showing “Moisture detected” error, that’s an indication that the charging port needs drying up before it can charge again. Moisture detected error has been observed in placed with high humidity. If you are in a location with high humidity, or if you previously wet your phone, you should consider air drying it. In order to prevent damage to the system, Samsung designs its water-resistant devices not to allow charging when there’s moisture in the charging port. To ensure that the charging port is completely dry, try to put the device in a place with room temperature and let it sit there for a few hours. Water naturally evaporates even in room temperature. You can also gently shake the phone to dislodge any possible presence of water in the port. Alternatively, you can place your phone inside a plastic bag and pour rice into it. Leave the phone in there for at least 48 hours to allow rice to absorb the liquid.

If you’ve already dried the phone using home remedies but the problem stays, have it dried professionally.

Charge using a computer

Some users in the past were able to fix charging issues in the past by charging their device thru a computer. If you haven’t tried this trick, be sure to do it. It’s simple and easy to do.

Charge on Safe Mode

If your device still works normally, try to restart it to safe mode before charging it again. This should let you know if an app is preventing it from charging. When on safe mode, no third part app will be allowed to run. So, if your Galaxy Tab S4 charges only on safe mode, that’s a clear sign of an app causing a problem.

To boot your Galaxy Tab S4 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. Charge the phone.

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 Galaxy Tab S4 is still problematic, repeat steps 1-4.

Reset app preferences

Apps can become a problem for a number of reasons but one of the most common cause is due to a disabled default app or service. In order to do a certain task, most apps depend on default Samsung or Android apps. If, for some reason, a necessary default app has been disabled, third party apps that might need it may not work properly. Such a situation can lead to problems. To ensure that all default apps are enabled, try to reset your app preferences with these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap More settings (three-dot) icon at the upper right.
  4. Tap Reset app preferences.

Reset all settings

Another good thing to do in this case is to return software settings of the device to their defaults without doing a factory reset. This is usually effective when dealing with issues due to some misconfiguration. Here’s how:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

Install updates

An often forgotten way to minimize bugs and, at times, fix known problems directly, is installing updates. Be sure to keep the system updated by installing updates for both Android and apps.

Factory reset

A drastic way to fix most software-related problems is factory reset. You only want to do this solution if none of the suggestions won’t help.

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  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.

Get Samsung support

If nothing has changed after you’ve exhausted all troubleshooting steps above, you should contact Samsung to set up repair or replacement request. As an end user, you can only do so much to troubleshoot an issue like this. You should let a Samsung technician check the hardware to fix the problem.

How to fix a frozen or unresponsive Samsung Galaxy Tab S4

The new Samsung Galaxy Tab S4 is an excellent tablet in its class but it’s not perfect. From time to time, even great phones and tablets can encounter bugs that can freeze the system. If you have an unresponsive Samsung Galaxy Tab S4, this article should 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.

What can cause Galaxy Tab S4 to freeze or become unresponsive

Some of the common causes why an Android device may freeze are the following:

  • temporary system slow down
  • Incompatible or poorly-coded app
  • overheating
  • slow performance
  • hardware malfunction

How to fix a frozen or unresponsive Samsung Galaxy Tab S4

Like most Android problems, there’s no direct way to know what causes Galaxy Tab S4 to freeze or becomes unresponsive. You’ll need to do a series of troubleshooting steps in order to both narrow down the factors and work out a solution.

Forced reboot

One of the common reasons why an Android device is unresponsive is a temporary bug. Such a bug can occur for any reason. If you find your Galaxy Tab S4 suddenly becoming frozen, forcing it to reboot must be the first troubleshooting step that you want to try. In older Samsung Galaxy devices with removable battery packs, disconnecting the battery is usually enough to fix a frozen system. Since the Galaxy Tab S4 has a non-removable battery, all you can do is to simulate the effects of having disconnected the battery by pressing and holding the Power button and the Volume button down at the same time for more than 7 seconds. This will force the device to restart it as if you’ve removed the battery and reinserted it.

Clear cache partition

Sometimes, Samsung Galaxy devices may encounter lag or freezing issues when its system cache is corrupted. To keep the system cache on your Samsung Galaxy Tab S4 in top shape, make sure to regularly clear the cache partition. Doing it once every few months should be fine. Wiping the cache partition after a system update is also recommended to lessen the chances of this cache from getting outdated. To do it:

  1. Power off the device.
  2. Press and hold the Power key, Home key and Up Volume key at the same time.
  3. Release all of the keys when the Android image appears.
  4. Press the Down Volume key to select Wipe cache partition.
  5. Press the Power key.
  6. Once Cache wipe complete appears, press the Power key to select Reboot system now.
  7. The device restarts once the wipe is finished.

Check for bad third party app

Not all apps are created equal. While majority of Android apps are fine, some may not be so. A few may cause problems with other apps or with Android. To see if an app is interfering with Android Operating System, put the phone on Safe Mode and observe it for some time.

To restart to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key.
  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. Release the Volume down key when you see Safe Mode on the device.

Once the phone has booted to safe mode successfully, all downloaded apps will be suspended. This means that only apps that came with the operating system will be allowed to run. So, if your Galaxy Tab S4 works fine on safe mode (make sure that you use it for a few hours) but becomes problematic again once you return it to normal mode, that’s a clear sign of a bad app issue. Use the method of elimination to identify which one is problematic. This is what you must do:

  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 Galaxy Tab S4 is still problematic, repeat steps 1-4.

  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Get Samsung support

In some rare cases, constant freezing or lag can be attributed to hardware malfunction or damage. If your Samsung Galaxy Tab S4 was dropped or exposed to elements prior to noticing the problem, there’s a good chance that bad hardware is the culprit. Let Samsung check the device if it continues to freeze after a factory reset.

Samsung Galaxy Tab S4 won’t charge due to “Battery temperature too low” error

“Battery temperature too low” error usually shows up in devices that’s exposed to very low temperature resulting to charging failure. If you have this error on your Samsung Galaxy Tab S4, learn what to do to address it.

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.

Problem: Samsung Galaxy Tab S4 won’t charge due to “Battery temperature too low” error

Hi. My tablet, Samsung Galaxy Tab S4 is not charging and gives me the error “Battery temperature too low”. With the charger plugged in and turned off (battery is depleted by now) the screen is alternating between the battery charging sign and a triangle with a thermometer sign.

Question: Can this be caused by a faulty pin in the battery connector to the motherboard? or can I rule that out completely and the issue is in the charging assembly/port? Before this happened, the battery couldn’t charge above 1-2% no matter how long I left it plugged in. So I tried to disconnect the battery connector and in the process I damaged a pin. After I patched it back somehow, I turned the tablet on and it showed a 20% charge despite before showing 1-2% for days. I was able to use the tablet (with the damaged connector pin) normally for the 20% charge but now I can’t charge it. Thoughts? Can this be because the battery was dead anyway and this is just a wrong error message?

Solution: Lithium-based batteries are like people who perform poorly when exposed to low or high temperature. Too much heat can permanently damage the battery while low temperature can either cause the battery to stop working for some time. If you want your phone to work properly, make sure that you use it where you can usually tolerate heat levels.

“Battery temperature too low” error usually occurs when your phone detects that the core temperature of the battery has dropped below 4°C (39.2°F). If you are in cold place or if the phone is exposed to cold, leave it in room temperature for a few hours and everything should be fine.

However, if there’s no way the phone has been to such cold place before (below 4°C) but it keeps on showing the “Battery temperature too low” error, this may be due to a broken resistor in the USB board assembly. This resistor is called thermistor and its job is to detect the core temperature of your device. It is set to trigger an error such as “Charging paused: Battery temperature too low” message to warn a user that charging can’t proceed due to low temperature. It’s possible that you may have damaged the thermistor when you tried to perform a fix on the device. This is a very tiny resistor in the charging board so you may have overlooked it during repair, or it may had been shorted during or after that procedure. The best way to fix a broken thermistor is to replace it but if you can’t find a replacement spare part, it’s best if you simply replace the entire USB charging port assembly.

Samsung Galaxy Tab S4 can no longer connect to Wifi

The Samsung Galaxy Tab S4 is the company’s most recent Android tablet and it’s packed with really impressive hardware specs. It should work without a hitch but no matter how good the device is, it’s not perfect. There would always come a time wherein issues may occur from time to time. Among the most common issues you may encounter are network problems especially with Wifi.

We have received reports from some of our readers who encountered having issues connecting their new tablets to Wifi networks. I personally encountered problems like this before and I know that it’s not really that serious. In this post, I will share with you the solution I’ve been using in fixing issues like this in the past. So, if you’re one of the owners of this device and are currently having similar problem, continue reading as this post may be able to help you.

Before we move on to our troubleshooting, if you are looking for a solution to a different issue, make sure you drop by our troubleshooting page as we’ve already addressed some of the most common problems reported by our readers. Find issues that are similar with yours and use the solutions we suggested. If you still need our help after that, then feel free to contact us by filling up our Android issues questionnaire.

What to do if Galaxy Tab S4 can’t connect to Wifi

Network-related issues may occur from time to time but it doesn’t mean they’re serious. There are times when they’re caused by some glitches in the system and there are times when some apps interfere with its normal operation. With all that being said, here’s what I suggest you do about it…

Solution 1: Forced Reboot

If this is the first time that your tablet cannot connect to a Wifi network, then try doing the forced reboot as it could be just due to a minor glitch in the system. It will refresh your device’s memory as well as reload all its apps and services. It might be the only thing you need to do and here’s how you do it:

  1. Press and hold the Volume down button first and don’t release it.
  2. Now, press and hold the Power key while holding down the Volume down button.
  3. Keeps both keys held down together for 45 seconds or more.

Once the phone has rebooted successfully, try reconnecting to the same Wifi hotspot to see if the problem got fixed. If it still can’t connect, then try the next solution.

Solution 2: Reboot Network Equipment

The next thing you should do if make sure it’s not a problem with the network. If you’re connecting to your own Wifi network, then it’s better to refresh the connection by rebooting your router or modem. Just unplug your equipment for a minute or two and then plug it back in. Once it’s ready, try having your tablet reconnect to the network and if it still can’t, then try your other devices to connect to the same network.

If your other devices cannot connect to the same network, then it’s a problem with your router or modem. You may have to reset it. However, if they can connect to the network and browse the web, then the problem is with your tablet. Continue your troubleshooting.

Solution 3: Reset Network Settings

There are times when network services may stop working and just need to be refreshed. So, you need to reset network settings to refresh the connection. Here’s how it’s done…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset network 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.

Once completed, the following changes will occur…

  • Stored Wi-Fi networks will be deleted.
  • Paired Bluetooth devices will be deleted.
  • Background data sync settings will be turned on.
  • Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
  • Network selection mode will be set to automatic.

If the problem continues after this, then try the next solution.

Solution 4: Reset All Settings

This will bring back the phone to its original configuration. Most of the time, this will fix any minor problems including network issues. It has the effects of a factory reset only that you don’t need to create a backup of your important files and data as they won’t be deleted. Here’s how it’s done on your Tab S4:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

Solution 5: Master Reset

After you’ve done everything and your Tab S4 still can’t connect to the network, then you need to reset your phone. A reset will fix any firmware related problems as long as the firmware hasn’t been modified in any way. However, make sure that you create a backup of your important files and data as they will be deleted during the problem. Once you’re ready, follow these steps to perform the Master Reset:

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  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.

How to fix a Galaxy Tab S4 if it is unresponsive or won’t turn on

Smartphones sometimes freezes or becomes unresponsive. Not all software bugs can be anticipated by developers to any electronic device can encounter a hiccup. In this post, we bring you solutions and troubleshooting steps that you can do when a Galaxy Tab S4 has become unresponsive, or worse, won’t turn on at all.

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: Galaxy Tab S4 is unresponsive and won’t turn on

Just purchased a new Galaxy Tab S4. I fully charged it yesterday. Today, I turned it on for the very first time. After spending about 10 minutes doing the initial setup (logging into Google and activating the devices security features), I was in the process of downloading apps from the Play Store when the screen, conversely the entire device, just turned off. Pressing the power button does nothing. The battery had been at 97% prior to it turning off. I’ve tried the pressing and holding down of the Power Button and the Volume Down Button for 45 secs. I tried that 3 separate times to no avail. I then tried the holding down of the Volume Down butting first THEN pressing and holding down the Power Button for 45 secs . I’ve tired this 3 times to no avail. Nothing works and I’ve had the device less than 2 days.

Solution: If it’s a brandnew device, the system may have frozen if while it’s updating downloading or updating apps, or when it’s trying to install a software update. This can sometimes occur if a user tries to interfere with the system when it’s trying to configure or set up something. If that’s not the reason for the problem, other factors like bad app, software glitch, or even hardware malfunction can come into play. To troubleshoot it, follow our suggestions below.

Forced reboot

This is the first troubleshooting step that should be done in this situation. Forced reboot is useful in cases wherein a device is frozen and unresponsive. To do it, just press and hold the Power button and the Volume button down simultaneously for more than 7 seconds to restart it.

Charge using a computer

If your Galaxy Tab S4 is still unresponsive after simulating a “battery pull” or forced reboot, the next good thing to do is to connect it to a computer via USB cable to simulate slow charging. Some users found this simple step effective in bringing their Samsung tablets back to life in the past. Make sure that you are using a known working USB cable when doing it. Leave the phone charged through your computer for at least 30 minutes before you attempt to power it back on.

Boot to Safe Mode

If your phone is not totally dead and you are able to power it down, you can also check if rebooting it to safe mode will help. Safe Mode is a separate software environment and is useful for checking third party app issues.

To boot your Galaxy Tab S4 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key.
  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. Release the Volume down key when you see Safe Mode on the device.

While running on safe mode, no downloaded apps will run. If your Tab S4 successfully boots to safe mode, one of the apps must be the culprit. Use the method of elimination to identify which one is problematic. This is what you must do:

  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 Galaxy Tab S4 is still problematic, repeat steps 1-4.

Master reset

If you can, try fixing the problem by booting the device to Recovery Mode so you can wipe it with a master reset. This is a drastic solution that often works if the reason for a problem is a software bug. Make sure to create a backup of your data before wiping the phone.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy logo screen displays, release all of the keys, the press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press the Power key to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press the Power key 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.

Repair

Not all Android issues can be fixed by an end user. If you are unable to boot the device to Recovery Mode, or if nothing changes after doing all the suggestions above, you can assume that the problem might be on the hardware side. To know what specific component may have failed is impossible unless a full hardware diagnostics can be done on the device. In your situation, the best people that can help is Samsung. Be sure to contact them so they can set up repair or replacement appointment for you.

Performance issues can be fixed by basic troubleshooting procedures. So, as long as there are no signs of hardware and liquid damage in your Tab S4, this problem could be fixed. Here’s what you need to do…

Run your table in Safe Mode – this is to temporarily disable all third-party applications and it’s necessary for us to determine if the reboots are caused by those applications because if so, then it would be a lot easier to fix them. You just have to find out which of the apps you downloaded and installed is the culprit and uninstall it. Here’s how to reboot your phone in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key.
  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. Release the Volume down key when you see Safe Mode on the device.

Wipe cache partition – it’s also possible that the cause of the reboots is the corrupt system cache especially if the reboots occur even in safe mode. In this case, you need to run your phone in recovery mode and then wipe the cache partition to delete the system cache and replace it with a new one.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy Tab S2 logo screen displays, release all three keys, then press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press Power button to select.
  7. When the wipe is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

If your tablet still keeps on rebooting after this, then you will have to reset it. Any software related issues can be fixed by a reset.

Perform the Master Reset – this will bring your device back to its default settings and configuration and probably fix the reboots. However, make sure that you make a backup of your important files and data as they will be deleted during the process. Also, make sure you know your Google ID and password as you will be using it to setup your tablet after the reset so that you won’t be locked out of your device. Here’s how the reset is done on your Tab S4…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy logo screen displays, release all of the keys, the press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press the Power key to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press the Power key 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.

How to fix Samsung Galaxy Tab S4 that’s running so slow or has poor performance

With its impressive hardware specs, you can always expect the Samsung Galaxy Tab S4 to be fast and unresponsive in every aspect. It must perform better than mid-range laptops released a couple of years ago. However, if it starts to run slow or shows poor performance, it could be due to apps or some firmware issues.

Software problems are seldom attributed to hardware issues provided the device hasn’t suffered either physical or liquid damage. So, if this is not the case with your Tab S4, then there’s really something you can do to make it run faster again. In this post, I will walk you through in doing some troubleshooting procedures that could regain the tablet’s performance so continue reading as this may help you one way or another.

But before we actually move on to our troubleshooting, if you have other issues with your phone, then visit our troubleshooting page as we’ve already addressed some of the most common problems with this device. In case you need more help with your problem, fill up our Android issues questionnaire and hit submit to contact us.

What you should do to make Galaxy Tab S4 run fast again?

We just need to find out if there are apps, third-party or pre-installed, that cause the problem. If there are, then the problem will be a lot easier to fix. If it’s also just a problem with the firmware, there are still a couple of procedures you can do to fix it.

Force restart your Tab S4 – before doing any complicated troubleshooting procedures, try to soft reset your tablet to refresh its memory and load all its apps and services. Some glitches may have been causing inconsistencies in the normal operation of the system and the forced restart can fix them. To do this, press and hold the Power and Volume down key for up to 45 seconds. Your device will reboot and observe its performance once it becomes active again. If the problem remained, then move on to the next procedure.

Reboot your phone in safe mode – we will now try to find out if the cause of the problem are some third-party applications. There are apps that can make your device, no matter how fast it is, slow like heavy apps and CPU-intensive games. By running your device in safe mode, you’re only allowing pre-installed applications to run and if the problem is indeed caused by a third-party, then your tablet shouldn’t have any issues while in this mode. In such case, the next thing you should do is find the culprit and uninstall it. Here’s how to reboot your Tab S4 in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key.
  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. Release the Volume down key when you see Safe Mode on the device.

Reset all settings – you would only need to do this if your tablet still runs so poorly even while in safe mode because if that’s the case, then the problem could be with the firmware. The first thing you must do is to see if it has something to do with the tablet’s settings or configuration that’s why you need to do this procedure to bring it back to its default settings.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

If the performance didn’t improve after doing the procedure above, then you will have to do the next couple of procedures to fix a possible firmware problems.

Delete the system cache – if the system cache gets corrupted or becomes obsolete, the first to suffer is the device’s performance and this could be the case here especially if the problem started without apparent reason. You need to wipe the cache partition to delete and replace the system cache with a new one. Here’s how it’s done…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy Tab S4 logo screen displays, release all three keys, then press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press Power button to select.
  7. When the wipe is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Perform the master reset – a reset can always fix performance issues provided that they’re firmware-related problems and not caused by hardware issues. I am confident that a reset will make your Tab S4 run faster again. However, make sure that all your important files and data are backed up because they will be deleted from your tablet’s internal storage. You may save them in the cloud or move them to your SD card or computer. After that, follow these steps to reset your tablet:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy logo screen displays, release all of the keys, the press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press the Power key to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press the Power key 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.

What to do if your Samsung Galaxy Tab S4 has a screen flickering issue

Depending on how the flickering started, it could be a minor issue caused by some apps or glitches in the system or it could be a serious hardware problem. If your new Samsung Galaxy Tab S4 got dropped and then this problem started, then it could be the latter but if it started without apparent reason or cause, there still could be something you could do about it.

Continue reading as I will walk you through in troubleshooting your Galaxy Tab S4 with a flickering screen. We’ll try to determine if it’s a hardware problem or a software-related issue. Remember that it’s a hardware problem, there’s only so much you can do about it. You better let the technician check it for you. But if it’s just a software problem, then you can fix it on your own.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

How to troubleshoot Galaxy Tab S4 with screen flickering issue?

The purpose of this troubleshooting guide is to determine if it’s a hardware or software problem and fix it if it’s the latter. Here’s what you should do regarding this issue…

Reboot your tablet first – before begin, make sure to restart your Tab S4 first because it’s always possible that the problem is just a minor glitch in the system. Some glitches are even caused by apps that are running in the background and doing a reboot will close all of them and thus, fix the issue. If this doesn’t fix the problem, then proceed to the next step.

Run your tablet in safe mode – this is to find out if the cause of the problem are some third-party apps or services. By running your Tab S4 in safe mode, you’re temporarily disabling all third party elements in your device. So if the problem is indeed, caused by one of them, the flickering won’t occur in this mode. If that’s the case, you just need to find the app that’s causing the issue and uninstall it. Here’s how to run your tablet in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key.
  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. Release the Volume down key when you see Safe Mode on the device.

Wipe cache partition – it’s also possible that the cause of the flickering are some corrupt system caches. While these are temporary and small files, they can still cause a lot of trouble if they get corrupted or obsolete and the immediate result would be issues with the performance of the device and that also includes screen flickering and other minor hardware problems. By wiping the cache partition of its contents, you’re not just deleting the cache and replacing it with a new set. Here’s how it’s done…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy Tab S2 logo screen displays, release all three keys, then press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press Power button to select.
  7. When the wipe is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Perform the master reset – this is your last resort and if the problem continues after this, then we can say that the problem is really with the hardware, specifically the screen. But before we can say that, your device should be brought back to its default settings and configuration. There’s a lot more things happening when the device is reset so this is potentially a very effective solution against this kind of problem. However, make sure to make a backup of your important files and data as they will be deleted during the process. Here’s how to reset the Galaxy Tab S4:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Samsung Galaxy logo screen displays, release all of the keys, the press and quickly release the Power key
  4. ‘Installing system update’ will show for about 30 – 60 seconds, then a ‘No command’ Android will appear before showing the Android system recovery menu options.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press the Power key to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press the Power key 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.

Once the reset is completed, continue your observation to know if your table still has a flickering screen because if so, then it’s time you brought it back to the store or shop so that a technician can check it up for you.

How to fix Samsung Galaxy Tab S4 that’s stuck on the black screen of death?

The black screen of death may happen to all mobile devices including tablets like the new Samsung Galaxy Tab S4. The most common symptom of this issue is that the screen turns black–hence the name–but aside from that, the device itself is unresponsive and doesn’t turn on no matter how many times press or hold the power key. It won’t even charge if you connect it to its charger and these symptoms would make owners think their device has some kind of a hardware issue.

It is normal to think that the black screen of death is a hardware problem especially if you knew that it suffered from either physical or liquid damage. However, if there were no signs or apparent reason, this could be just another minor issue involving the firmware and in such case,  the problem can easily be fixed. Continue reading below as I will share with you the solution we’ve been using to address problems like this.

Before anything else, if you have other issues with your device, try to browse through our troubleshooting page as we’ve already addressed several issues with this device. Odds are that we’ve already published a post that tackles similar problems. Try finding issues that have similar symptoms with what you currently have and feel free to use the solutions we’ve suggested. If they don’t work for you or if you still need our help, then fill up our questionnaire and hit submit to contact us.

How to troubleshoot Galaxy Tab S4 with black screen of death?

As I said earlier, this kind of problem could be just a minor issue with the firmware because most of the time the black screen of death occurs if the firmware crashes. With that being said, here’s what you should do about it…

Perform the Forced Reboot procedure

It must be the first thing you should do and it could be the only thing you needed to do especially if the problem started without apparent reason. If you’re familiar with the battery pull method to fix older phones that stopped responding, the forced reboot is the counterpart of that procedure only that we do this one on devices with non-removable batteries. To do this, press and hold the Power and Volume down keys for up to 45 seconds. If done correctly, your tablet may turn on and boot up like it normally does that it could be the end of the problem. But if your device still doesn’t respond after the first try, then do it a few more times to make sure you’re doing it right. If it still doesn’t respond after that, then try this instead…

  1. Press and hold the Volume down button first and don’t release it.
  2. Now, press and hold the Power key while holding down the Volume down button.
  3. Keeps both keys held down together for 45 seconds or more.

It’s actually just the same as the first procedure but in this one, we try to press and hold the volume down button before the power key. If you do it like this, it will give you the same result but if you press and hold the power key first, your tablet may continue to be unresponsive. However, after doing this correctly and your device is still not turning on, then it could be because of a drained battery.

Charge your tablet and do the Forced Reboot

Having a depleted battery isn’t really a problem because most of the time your phone would respond when there’s current flowing through its circuits. However, there are times when a drained battery may also cause a firmware crash since some services and hardware components may not be shut down properly. If this is the case with your Galaxy Tab S4, then no matter how many times you perform the forced restart procedure, your device would still not turn on because there’s no battery left to power it up. So, to address this, here’s what you’re doing to do:

  1. Plug the charger to a working wall outlet.
  2. Connect your Galaxy Tab S4 to its charger using the manufacturer-supplied cable.
  3. Regardless whether the tablet shows it’s charging or not, leave it connected to the charger for at least 10 minutes.
  4. After that, press and hold the Volume down button first and don’t release it.
  5. Now, press and hold the Power key while holding down the Volume down button.
  6. Keeps both keys held down together for 45 seconds or more.

If your device boots up after this, then that’s the end of the problem but if not, you should bring it back to the store or shop so that a technician can check it up for you. I hope that this troubleshooting guide can help you one way or another. Thank you for reading!
