How to fix your Samsung Galaxy S8 that’s stuck in bootloop [Troubleshooting Guide]

A bootloop is when the phone cannot continue the boot up process and just before it reaches the home screen, it reboots only to be doing the same thing over and over. Some of the Samsung Galaxy S8 owners have contacted us about this problem saying their devices won’t continue the usual booting up process because they restart after getting past the logo.

So, in this post, I will tackle this problem and suggest things you can do to see if there’s something we can do to make your device continue booting. We will try to rule out possibilities until it’s clear what the cause is or what triggers the issue. We understand that it’s a brand new phone and that it should work flawlessly that’s why we urge you to perform basic troubleshooting so you can go back to the store as soon as you find out the problem is serious.

But before we jump right into our tutorials, if you happen to find this page because you own the same device but are looking for a solution to a different issue, then try to visit our Galaxy S8 troubleshooting page for we have already answered hundreds of issues reported by our readers before. Find ones that are similar with yours and use the solutions we suggested. If they don’t work for you or if you need further assistance, contact us by simply filling up our Android issues questionnaire.

Step-by-step guide to troubleshooting Samsung Galaxy S8 that’s stuck in bootloop

We just have to know or find out if this problem can be fixed without any help from a technician. If, during our troubleshooting, we find out it’s more serious than it seems, then you should immediately go back to the store and have the phone replaced provided the problem wasn’t caused by liquid and/or physical damage. Now, here are the things you can do…

Step 1: Make sure the Power key isn’t stuck or damaged

When the power key is stuck, the device would enter a bootloop wherein it powers on but shortly after the logo shows on the screen, it shuts down only to enter the same vicious cycle. You can actually leave the phone doing this same thing over and over until the battery is all drained.

Fortunately, for stuck power keys, you can fix it by simply pressing it many times and releasing it every time. More often than not, the cause of the stuck Power key is the casing. So, if you have third-party cases you just put on and then this problem started, you should consider checking the Power button as it may have been stuck.

As to damaged power key, it’s included in the hardware so you really don’t have to do anything about it except, of course, bringing the phone to the tech and have it checked. You just have to see if the key still snaps when you press it because if it doesn’t and if it’s not fixed by pressing it many times, then it’s damaged.

Step 2: Attempt to boot your phone in Safe mode

Do this if you are sure that the power key is just fine. After all, you cannot actually enter the mode if it’s stuck as the loop may never be broken. So, after checking the power key and it looks okay, try booting your Galaxy S8 in safe mode to temporarily disable all third-party apps that might have something to do with the problem. This is how you start your phone in 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.

If your phone can successfully enter this mode, then we’re halfway to solving the problem as we’ve already made the device boot up successfully. So, the next thing you should when in this mode is to find the apps that prevent the phone from booting up successfully. Once found or if you are suspecting something, then you should uninstall them one by one until the phone can boot up successfully in normal mode.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

However, if the phone cannot boot up in safe mode, then move on to the next step.

Step 3: Try to start the phone up in Recovery mode

The Android system recovery is your last resort. Usually, firmware issues won’t affect the capability of an Android device to boot in this mode provided the firmware isn’t modified at some point. So, there’s a big chance you can bring your device to start in this mode. So, try the following steps to see if your S8 is still capable of going into recovery:

  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).

Assuming the phone is capable of booting up in this mode, then you should try wiping the cache partition…

  1. Press the Volume down key several times to highlight “wipe cache partition.”
  2. Press the Power key to select.
  3. Press the Volume down key to highlight “yes” and press the Power key to select.
  4. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  5. Press the Power key to restart the device.

If the problem isn’t fixed by wiping the cache partition, then the next step might help.

Step 4: Perform the Master reset if possible

We are now at a point wherein we need to verify if the phone can still work properly if brought back to its original configuration. You may not be able to backup your personal files and data especially if the phone cannot boot up in safe mode, but a reset is necessary at this point because if it still fails to fix the problem, you need to bring the phone back to the store and have it fixed or replaced. We technicians often resort to resetting the device to protect the privacy of our clients unless they tell us explicitly not to do it for the sake of their files.

It is all up to you if you want to reset your phone or not and if you decide to do it, then 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 data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

After a successful reset or if it didn’t go through, then you should bring the phone back to the store and have it checked. It’s all up to the tech if he recommends it for replacement.

How to fix Samsung Galaxy S8 that’s stuck in infinite boot loops (easy steps)

Phones that cannot completely boot up may have issues with their firmware. At least, that’s the most logical thing to assume considering the fact that the boot sequence is done by the operating system. But then again, there are other possibilities of a more serious hardware problems. In other words, we won’t know for sure why the phone can’t completely boot up. That’s the same thing we have to assume if the phone is stuck in a boot loop wherein the device can power up its hardware, show the logo but fails to reach the home screen as it turns off by itself and powers back on. The cycle will continue until the battery runs out.

In this post, I will share with you the procedure we’ve been doing to fix this problem but it effectivity depends on how the problem started. This isn’t the first time we encountered this problem so we already know a thing or two that could help bring your phone back to its original state. So, if you’re one of the owners of this phone and are currently bugged by a similar problem, continue reading as this post may be able to help you one way or another.

If however, you are looking for a solution to a different problem, drop by our Galaxy S8 troubleshooting guide for we have already addressed the most common issues with this phone. Find problems that are similar with yours and use the solutions we suggested. If they don’t work for you or if you need more help, then feel free to contact us through our Android issues questionnaire.

How to fix Galaxy S8 stuck in infinite boot loop

As always, boot loops are a result of one or some issues with the firmware. There are even times when the firmware is the problem. But let’s go straight to fixing this problem and this is what you need to do:

The Solution

Boot your phone up in recovery mode and wipe the cache partition. That is if the problem started without apparent reason or after a firmware update…

  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 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 the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

If this doesn’t work, then you should reset your phone. However, you may lose all files and data stored in your phone’s internal storage, but at this point in time, it’s necessary to reset your device.

This is how you reset your S8 that got stuck in boot loop…

  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 data / factory reset.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

The reset is your last resort so if it fails, you must bring the phone to the service center so that a technician can fix it for you. The reset is the best shot you have to fix this problem but if it fails, there’s nothing much you can do.

Problem #1: Galaxy S6 screen turns black but blue LED light is flashing

So I received an S6 from a friend after the screen went black, because her mother decided to just buy a new one instead of trying to fix it. I’ve been trying to fix it for the past 5 hours now, and nothing from the web has really affected it yet. The screen is unresponsive and only the blue light is flashing. The first charger I used made the blue light turn off temporarily, but I switched chargers because no charger indicator lit up either. The second charger has also had no affect but to bring back the blue light. I’ve tried also pressing power button, both volume buttons, and the home every way possible but nothing worked.  I’d really like to have this phone. Can you help? I’m also not sure about the android version, but the black screen only started a couple days ago. — Anonymous

Solution: Hi Anonymous. Looks like you have a hardware issue at hand. As our blog does not provide hardware troubleshooting and solutions, the only suggestion we can give you is the steps on how to boot the phone in alternate modes. If your phone remains unresponsive after trying all the different hardware button combinations, that’s proof that hardware failure is to blame. It can be due to a bad screen assembly or an unknown hardware problem.

In this case, kindly approach a qualified Samsung technician for assistance. These are the steps on how to boot your phone in other modes:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #2: How to recover files from Galaxy S6 with bootloop issue

Good afternoon, My name is Ozz. I am the owner of a Galaxy S6 that is in a boot-loop every 16 seconds. I have data on my phone that i never backed up that holds some sentiment to me such as photos from my son’s birth, photos from my mother and text from my mother that is now deceased. In an attempt to recover the data i sent my phone over to drive savers in California. They are sending my phone back because they could not help me recover the data. According to them, the files were corrupted by the boot loop and their technology could not read or retrieve them from the chip. My phone still has the data in it. However, with the boot loop i am not able to email it, back it into a cloud or perform any black magic in the 16 seconds i have to work with. The loop restarts the phone until the battery runs out. At the moment i cannot find out what is the most recent version on the phones software but i am working on getting that for you. Because this happened in September i believe it was Marshmallow. Is there anything you can do to help me? Any advise or guidance in keeping this phone from being a sentimental paperweight would be much appreciated. Thank you, — Osvaldo

Solution: Hi Osvaldo. There are a number of possible reasons that can result to bootloop issue. In general, these causes can be categorized into two — software and hardware. If it’s a hardware issue, there’s very little to nothing that you can do about it. It can be caused by a bad component like a faulty capacitor or any other hardware part. In this case, you need to submit the phone to Samsung or to any qualified repair shop so a thorough hardware check up can be done.

On the other hand, if the problem is due to bad software, there’s a chance that you may be able to fix it yourself. Bootloop is the usual result of a rooting or flashing procedure gone wrong. Because you never bothered to mention the circumstances that led to the boot loop issue, we can only speculate that you may have tried to modify the official operating system. If this is the case, the best thing that you can do is to reflash a stock firmware. Depending on the current setup of your phone’s software, this may or may not wipe the phone’s internal storage. Unless you can stabilize the phone and check the constant boot loop issue, there’s no other way for you to access your files in that phone. The thing is, the only effective solution for this boot loop issue (assuming that there’s no hardware issue involved) may also wipe the internal memory that holds your files. Needless to say, the chances of getting your files back is very slim.

Problem #3: Galaxy S6 Edge Plus can’t exit out of Emergency mode and screen turns black

Hi, I’m hoping you can help me. I have a Samsung S6 Edge Plus which I love… until now.

Problem 1: This morning it got stuck in emergency mode. This had not happened before. I tried to fix it by long pressing the power and then tapping the third option (emergency mode off) and nothing happened. My first thought was that my touch screen was malfunctioning so I powered off/on and restarted the phone a few times. When the phone was powered up, it would ask me to put in my “pattern” to unlock instead of my fingerprint as a result of the power restart. I would attempt to do this but unfortunately when the phone because it was in emergency mode it wouldn’t allow me to draw my pass code pattern with my finger.

Problem 2: So because I started and restarted the power quite a few times, I think I have been locked out somehow. What I mean by locked out is that I no longer see the lock screen. I now see just a black screen. Please help me!! I attempted to fix the problem and inadvertently made it worse. Thanks. — Lauren

Solution: Hi Lauren. There are two ways to exit emergency mode:

  1. The first one is by holding the power button, then tapping the “Emergency mode” option in the screen.
  2. The second option is done by tapping MORE (the three-dot line) in the Emergency mode screen on the upper right hand side of the screen. Once you’re in that section, simply tap the “Turn off Emergency mode” option.

If you can’t turn emergency mode off using any of these options, there may be an unknown operating system glitch causing it. We recommend that you try  booting the phone in Recovery mode first to see if you can make the screen respond positively to it. If you can turn the screen on via Recovery mode, then make sure that you first wipe the cache partition. To do that, follow these steps:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Wiping the cache partition may or may not fix the issue. If the result is negative, the next logical step for you to do is to do a master/factory reset. Simply boot the phone again to recovery mode to do it.

Problem #4: Galaxy S6 fast charging stops working

For some reason, my fast charging plug and cord started not working with wall outlets. I made sure to check more than one. On the second wall outlet, it only charged for a couple of seconds before the phone buzzed at me about being low on charge. I plugged it into my computer, and my phone was recognized. However, it won’t charge when I plug the cable into my laptop. Right now, however, I have it plugged into a portable power unit, and while it’s not making leaps and bounds with charging, it’s at least showing that the phone is charging. With everything else, the charging indicator wouldn’t come up. Would it be best to get a new cord, or is it a problem with the fast charging plug? Or, is it another issue entirely? Thank you in advance for your help! — Michelle

Solution: Hi Michelle. In many cases involving fast charging, it’s almost always either a bad USB charging cable, or a malfunctioning charging port. Try getting a new original charging cable first to see if that will make any difference.

If a new USB cable won’t fix the problem, try to do some basic software troubleshooting such as:

  • wiping the cache partition,
  • booting in safe mode, and
  • factory reset

If these software troubleshooting won’t change anything, that’s proof that the charging port may be bad. In this case, you need to consider phone repair or replacement.

Problem #5: Accidentally dropped and water-damaged Galaxy S6 won’t turn on

My daughter jumped into a swimming pool fully clothed to rescue a child in trouble. Her Samsung Galaxy S6 Edge was in her pocket and got wet. The phone turned off but she turned it on and it worked. She turned it off and dried it out for 2 days in rice. The phone worked and charged up for about 3 months but she dropped it and cracked the screen and now it will not turn on. There are no lights and it will not charge or connect to a PC. It is only 6 months old now.  I have tried the sequence of button presses to hard reset etc but it is completely unresponsive. Someone said it could be repaired with a battery and replacement screen but I need to know if the phone is actually repairable or whether it is likely to still be broken after expensive battery and screen replacement. Many thanks for any help. — Nell

Solution: Hi Nell. Frankly, there’s no way for us to know for certain if the phone that’s been wet and accidentally dropped can still be repaired. When it comes to hardware issues, only the attending technician can give a more or less accurate assessment. Armchair technicians like us can only speculate. In other words, we need to physically check the phone in order to tell if it’s within saving. We strongly suggest that you approach a technician so the device can be assessed properly. Only then can someone give you a full picture on what can be done.

Problem #6: Galaxy S6 Edge Plus contacts keep coming back even after accounts have been removed

Hello. I have a problem with my Samsung Galaxy S6 Edge Plus phone. I am connecting the phone to multiple accounts, my Hotmail account, my Gmail account, and my Samsung account. The problem is with my accounts list. I try to delete some of my contacts. I have the message (delete contact from linked account too?) and i choose YES. However, once i connect my phone to WiFi and for some unknown reason. The deleted contacts keep coming back. I have tried to uninstall my Hotmail account as i suspected it is the culprit. But in vain. Whatever I do deleted contacts keep popping back. I would appreciate any advice you could give me about this issue. Thanks in advance. Kind regards. — Sam

Solution: Hi Sam. The most probable reason why some contacts appear to keep coming back even after deleting some accounts is that there’s still another or some accounts left that are also associated with said contacts. To check, do these steps:

  • connect to your wi-fi network
  • disable master sync (pull down the notification bar and turn off Sync)
  • observe how the phone behaves.

If the problem won’t reappear while master sync is off, that’s a confirmation of our hunch. In this case, you need to narrow down what account is causing the trouble by removing them one by one, until you’ve pinpointed the true cause. Better still, simply do a factory reset and only install the accounts that you need.

Problem #7: Galaxy S6 won’t connect to Bluetooth car kit after updating to Marshmallow

After updating my Samsung phone from Lollipop to MM, the device is no longer able to have a connection with my Volvo XC60 2010 Bluetooth car kit. I tried every trick in the book, nothing works. Connection is made shortly between car and phone, but the connection drops before the device syncs, and the connection is not re-established automatically. As said, it worked flawlessly before the update. The carkit bluetooth is fix pin (1234), so maybe blacklisted in my device’s config settings? Samsung tells me it’s the Volvo software not being compatible with MM, which implies I have to buy a new car, or go back to Lollipop. The latter is not possible, Samsung tells me (which I find hard to believe). I need this issue fixed, the MM update (which I didn’t ask for, but was pushed onto my device automatically) should aim to improve the functionality of my device, not disable it’s bluetooth functionality. Or it should provide me with an option to go back if I’m desperately unhappy with the update. Which I am. — AB Morrien

Solution: Hi AB Morrien. Your issue is not different from similar issues from other smartphone users (both iOS and Android). It may look a Samsung issue since the problem occurred right after installing Android Marshmallow but the heart of the issue is really on compatibility. Hard it may be to believe but the cause of your problem is most probably due to an outdated car kit system you’re using. As a networking standard, Bluetooth works at two levels: physical and protocol levels. Since your car kit and phone worked before, the problem must lie at the protocol level, meaning both devices are now having disagreement on how and when to send and receive bits of data. The system update on your Galaxy S6 must have changed some settings or initiated to use new Bluetooth profiles or services that your kit does not yet support.

Bluetooth systems evolve over time and most smartphone manufacturers lead the pack when it comes to implementing the latest Bluetooth protocols available. The same cannot be said of auto makers or car kit systems though. It’s not uncommon to hear reports from users experiencing connectivity or compatibility problems between their phones (iOS or Android) and their car’s car kit after installing the latest update. Bluetooth problems between smartphones and car kit systems can be categorized in general forms:

  • No sound/audio issue
  • Failure to pair properly
  • Intermittent/regular disconnection

We strongly suggest that you contact your car maker to see if they can still update the software of your car kit. As we’ve pointed out before, car and car kit makers are notoriously irresponsible when it comes to updating Bluetooth software but it’s still worth trying. If they cannot provide a software update, your only lies on the chance that the problem is Android-related.

While we think that the problem is on your Bluetooth car kit, that doesn’t mean that your Galaxy S6’s system is perfect. When Android 4.3 was initially released, the update also included support for Bluetooth Smart technology. Unfortunately, that update was found to be buggy as far as Bluetooth connection was concerned because it shuts off Bluetooth feature every time a device discovers a certain number of Smart devices. An update was released with Android 4.4 but then again a separate Bluetooth problem also surfaced when Android 5.0 became available. That said, there’s nothing much that you can do but hope that a new update will fix the issue right now (assuming of course that the problem is on Android side). You may ask if there’s a way to identify where the problem lies. Unfortunately, in a case like this, there’s really no way to know for sure. We know it sucks but that’s the reality with Bluetooth technology.

To see if the problem is due to basic pairing issue, consider resetting the car kit’s software to defaults via factory reset. Consult its manual or do some research on how to do it. Once you’ve factory reset the device, do the same for your Galaxy S6. Then, once both of their software are on default, try pairing them one more time. If that won’t fix the problem still, you either accept the fact that you need to change the car kit to something new, or simply wait until a new Android update is released with an accompanying “fix.”

Problem #1: Galaxy Note 4 won’t power on

It is Lollipop or Marshmallow but I don’t know which.

The phone was working fine. I was online chatting with a friend while my Note 4 was charging then I locked the screen and started to watch an episode of a show on my television. I check my phone about 10 minutes later and there’s no life in it. I tried to power it on by holding onto the power button. Next I attempted to take out the battery for a minute and then put back in and try to turn it on. After that I looked at a few possible solutions offered here. I’ve tried taking out the battery holding on to the power button for 90 seconds then putting the battery back in and trying to turn on the phone by holding on to the power button, and also then doing the first part over again but this time putting the phone on charge for 20 minutes with the battery in before attempting to turn it on. I don’t know what to do the light that’s usually there to let you know that it’s charging isn’t even there. Thanks for helping or trying to help even if I have to bring it into a shop. ^_^ — Bhupinder

Solution: Hi Bhupinder. If your phone won’t respond to any hardware button combinations at this time, that’s a clear indication that either the battery has died, or a component or set of components are no longer working. Either way, the best thing to do is to have the phone physically checked so it can be repaired.

Problem #2: Fixing Galaxy Note 4 bootloop issue

My phone died. I turned it back on to see If i could check a message with a little bit of juice and it turned for a minute and then turned off. Ever since then it  will not turn on. When I press the power button  it vibrates and says Samsung Galaxy Note 4 for 2 seconds and then it turns off for 4 seconds and it continues to do this cycle and does not stop unless I take the battery out.

When I first connect the charger it shows a charging icon and then immediately goes back into that mode where is says Samsung Galaxy Note 4 for 2 seconds and then turns off over and over again. We got a new battery and that’s not the problem.

I tried the soft reset, the hard reset, the factory reset, the reboot, the recovery mode, it won’t let me get into anything. 

I took it into the store they could not do anything. Please give me a solution or suggestion. Thank you. — Sarah

Solution: Hi Sarah. The issue you’re experiencing right now is what we call a bootloop issue. Most of the time, this issue is caused by faulty software although there are some rare cases wherein hardware is to blame. To fix it, we usually recommend that you boot the phone in recovery mode and do a factory reset. Since you’ve already tried without a positive result, the next best thing to do is to flash a custom or stock firmware. This procedure can be done by booting the phone in download mode first. If you haven’t tried flashing an Android device before, make sure that you use Google to search for online instructions.

Now, if flashing a ROM won’t the issue, that means that there may be a hardware problem behind this trouble. Make sure to contact Samsung or your wireless carrier for a warranty repair or replacement.

Problem #3: Galaxy Note random restart/ won’t power on

Put an SD card into phone to get my photos on to the phone. Since this time my phone turns off all the time. SD card has been removed (and the photos).

When the phone turns off i can’t turn it back on for a number of hours. It currently takes longer and longer.

When i try to turn it on it goes to the Samsung name page,  freezes, turns off, restarts (on its own). Phone becomes very hot when this occurs. Only way to stop it is to take battery out.

Does the same thing even when attempting to turn on in safe mode.

If phone does turn on, will turn off randomly – no pattern found in which apps are open when this occurs.

Soft reset did not work.

Can not yet turn phone back on to try clear cache or other suggestions made. — Janneke

Solution: Hi Janneke. Sounds like your issue is similar to the ones above. Please refer to the suggestions for each case to see which one will work for you.

Problem #4: Galaxy Note 4 sometimes loses app icons and won’t load them

Applications that I downloaded TO the SD card ON this device used to be able to open and work properly. Now, they can’t be opened. In fact, they don’t fully register at all. I say “don’t fully” because when I click on the “ghost icon”, it says ‘application not installed’ and then automatically opens the games’ page in Google Play, and the page offers the choice for me to install it. However, apps that aren’t installed on the phone don’t leave icons behind, the icons are removed too. But these leave behind this weird icon of a transparent android picture with a mini icon of an SD card in the lower right corner.

Not only all that, but once in a blue moon, the Apps WORK and ARE registered AND installed!!

Also, all of these details were of true value BEFORE AND AFTER upgrading to Lollipop.

I’m stumped…

If you need me to send screenshots, let me know.

I would GREATLY APPRECIATE any and all help you can offer.. I’ve been trying to figure it out for a long time.

Thanks again! — Max

Solution: Hi Max. This is a phenomenon that we’ve observed on other Samsung devices that run Android OS other than Lollipop so we know this is not an isolated case. There seems to be no definitive answer as to what causes this situation but we know that a simple restart usually fixes it. If you’ll encounter the problem again, don’t forget to restart the phone to see if it will work as a workaround. If not, try wiping the cache partition.

Following an update, there’s a chance that the cache partition will become disorganized, cluttered, or contain outdated and irrelevant files. While updates like Lollipop are supposed to automatically create a new cache, this does not always happen in reality. One of the main reasons why so many users are complaining about slow performance, lag, freezing, or any other totally unrelated issues after updating to Lollipop (or any other OS) is a corrupted cache partition. We think that this is also the reason for your case. If you haven’t tried clearing the cache before, here are the steps to do it:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight Reboot system now and hit the power key.

Problem #5: Galaxy Note 4 losing battery power and randomly reboot

Hello. I’ve had a look through your forums and couldn’t find a solution to my problem. I’ve had this problem for a while now. The battery on my device drains really fast, and occasionally will turn off without notice. It will then restart but once booted, will restart again on a continuous loop until I remove the battery and then restart whilst plugged in to a charger.

I have multiple batteries with separate battery chargers as I thought this would be the best solution. I have also recently reset my device to factory settings but has continued with the same problems after only installing a few small apps. No games.

Amy help would be much appreciated as I use my phone for work.

Thank you. — David

Solution: Hi David. If you want to get to the bottom of this problem, doing a factory reset is not enough. Because the problem appears to be not related to the battery (as you have been using at least more than one), it can only be caused by a bad hardware, apps, or firmware. You need to narrow the causes down further. Unfortunately, there’s no easy way to do this.

To see if an app is responsible, we recommend that you do another round of factory reset and observe the phone for at least 24 hours without installing any app. If battery consumption will appear normal and/or if the phone won’t restart on its own, that’s your clue to start getting rid of whatever apps you are planning to install.

Alternatively, you can observe the phone for at least a full day after booting in safe mode. While safe mode is enabled, third party apps will be prevented from running so will still tell you if you’ve installed a problematic app.

If there’s no change after doing any of the procedures above, we suggest that you call Samsung for a repair or replacement.

Problem #6: Galaxy Note 4 unable to text and call when using mobile data/weaker LTE signal after update

Hello. I have some experience working with Samsung ROMs and firmware, but i have run into an issue i can quite put my finger on. The problem starts when i update to any baseband above BOE2. I have clean flashed the newest update and the same results occurred. The issue is whenever i try and use mobile data i lose my entire connection (texting, calling, etc). I have troubleshot the issue with my provider and they claim nothing has changed. I contacted Samsung Support and only received an offer to send my phone in to be looked at.

Now i know this issue is not just me since i have found numerous posts on XDA and the like about signal issues after a specific update.

Doing some digging i found that the tower my phone connects to without the issue is different and closer than the tower i connect to after the update. When i do have signal its only about 3 bars LTE where i used to get 5 bars LTE. So it would seem the issue resides within the modems firmware. To fix the issue i am currently clean flashed back to BOE2 and have nonissues what so ever.

Now with that aside, my question i have for you is…Have you come across a solution for this issue? And if not would a 5.1.1 custom ROM work with the BOE2 modem?

Device: SM-N910W8

Modem: BOE2 (MTA) — Chris

Solution: Hi Chris. To answer your question, the answer is no. We haven’t encountered this issue yet until now and we’re not aware of it being discussed in other forums. That’s probably because the issue appears to be carrier-specific, which means that users like you would rather post the question in their carrier’s technical support site rather than ask us.

Anyway, we still consider this problem to be best addressed by your carrier. First of all, the firmware version on your phone comes from them. There’s a chance that it may be poorly coded, or it may have encountered a conflict with a particular app on your phone. The developer team that built the firmware should check that. There’s no way for us to know which is which.

Secondly, the weak LTE signal issue after the update may or may not be linked to the first one. It’s up to your carrier which “cell” in their network your device will be assigned to. The change may or may not be the result of firmware modification. The only thing that you can do right now is let them know about the issues so they can do something about it. We know how frustrating it can be to sometimes talk to customer support representatives (who may only be trained to handle account- or billing-related questions) so make sure that you demand to talk to their technical support team.

Problem #1: Galaxy S4 boot loop issue after flashing custom ROM

I’ve a Samsung Galaxy S4 i9505 running on stock Lollipop 5.0.1. I’ve been trying to flash a custom rom on the phone for some time now, but I get stuck on a boot loop every single time. I have to revert to my stock firmware either through odin on my pc, or just restoring my backup through recovery.

I’ve tried more than 5 different custom roms to no avail. I’ve also tried different flashing methods. First, I used Philz Touch recovery. Then I used the wonderful Flashfire from Chainfire. And then I tried TWRP. It was on TWRP that I came across: “E: Unable to mount EFS folder”. I did a little research and I found out that my EFS folder is empty (or at least, I can’t see anything in the folder, even using Root Explorer). However, my phone is fine. No issues with network or Wi-Fi. My IMEI also seems untouched.

So, I’m wondering, is it possible that’s the cause of my boot loops? If it is, how can I solve the issue? And if it isn’t, what could be the cause of the boot loops, and how do I solve it? — Emmanuel

Solution: Hi Emmanuel. Any type of software modification can potentially result to boot loop issue but it’s not necessarily due to a corrupted EFS folder. EFS folder contains sensitive information about your phone like configuration and identifying information of its radios, network-critical phone numbers (registered number for a  network-locked phone), IMEI, among others. Some custom ROMs intentionally leave this folder untouched but others may modify it to unlock other functions. The problems that follows after EFS folder corruption usually includes phone being unable to connect to Wi-Fi or mobile data, unable to establish a network or cellular connection, and not being able to read a SIM card. Since you are not experiencing these problems, there must be another reason for the boot loop issue on your device. The thing is, there’s no way for us to know what the specific cause of the problem is. Any of the flashing processes you’ve tried may have compounded the initial bug which may have now spread and resulted to a number of glitches. Again, there’s no way to know exactly what went wrong.

If you cannot stop the boot loop issue after flashing a custom ROM, consider sticking to a stock firmware.

We also recommend that you visit XDA Developers website for more information about the custom ROMs you’ve tried. If you’re lucky, you may be able to contact the developer of the custom ROM you’ve used. Make sure that you mention the issues to them so they can see if there are available workarounds or more in-depth troubleshooting and diagnostics.

Problem #2: Galaxy S4 and apps keep freezing

Hello. So i had issues with SIM card not detected, RESTART phone. I managed that problem by stuffing objects under the phone cover or pressing around the SIM card. It would happen only a few times per month so it wasn’t a huge deal.

Those errors started to get more frequent and then my phone would start freezing and then shutting off. I’d have to take the battery out of the phone and then restart it.

All apps and programs experience the freezing. Snapchat, Whatsapp, Twitter, my standard messaging folder.

The phone is basically unusable right now.

Also, I reformatted the phone. Still the same problems. Thank you. — Alex

Solution: Hi Alex. You must address the identified hardware issue first (possible malfunctioning SIM card slot) before doing other stuff. That factory reset (usually what we call the “ultimate” software fix) did not change anything is an indication that this is not a software problem. The SIM card probably keeps connecting and disconnecting from the system due to a faulty SIM card slot. This cycle of connecting and disconnecting can cause the operating system to crash or the cache to get corrupted. With the operating system constantly having to deal with a malfunctioning hardware, it’s also about time when apps start to show problems.

Again, if factory reset did not fix the apparent app problems you have here, there’s no other software troubleshooting that you can do. Make sure to have the phone checked for hardware errors.

Problem #3: Poweramp widget buttons not working when on Galaxy S4 lock screen

Sorry for my poor English in the video. I was a little confused while taking it (smiley) I’ve purchased Power amp long time ago at it works perfectly on my Samsung Galaxy Note 4. Recently I purchased a Galaxy s4. Very nice phone too. No problems with all the other applications that I use. Just the Poweramp that is doing these strange things in the video. The widget works incorrectly, when I lock the screen and unlock it the buttons became white and not usable. Same for the buttons when I slide the screen down when the phone is unlocked. Sometimes the only way to exit the app is by force stopping it. All the information needed you can find in the video.

Also, when I plug the headphones in the jack the music doesn’t start automatically and doesn’t pause. when unplugged even those options are checked in the settings menu. I will appreciate if I get some help to get rid out of these problems. Thank you in advance (smiley).

Best regards. — Ivo

Solution: Hi Ivo. We appreciate the effort of contacting us and making a video of the problem. Based on your description and the video, there’s no apparent problem on the touchscreen so this must be a bug on the app or widget. We recommend that you try the basic software troubleshooting first like wiping the app’s cache and data, deleting the cache partition, or factory reset. If all of these procedures won’t help, the best party that should be able to help you is the developer team of the app itself. If you paid for their app, you can most likely contact them to get for support. Make sure that you let them see the video so they can easily evaluate their product.

For easy reference, here are the basic software troubleshooting steps that you can try first:

How to delete an app’s cache and data

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Choose the name of the app that has been going rogue.
  • From there, you will see the Clear Cache and Clear Data buttons.

Clear Cache clears out the temporary files of an app that are possibly causing its erratic behavior. It is very safe to do since it retains your app settings.

If clearing the cache fails to solve the problem that you are encountering in an application, the next thing that you have to consider is to clear the data of your app. Accessing the Clear Data button involves steps similar to finding the Clear Cache button.

How to delete S4’s cache partition

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key
  • When the phone vibrates, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select. The phone will automatically restart after the cache is wiped.

How to Factory Reset a Galaxy S4

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Problem #4: Galaxy S4 won’t charge and turn on

Phone is around 2 years old. A few months ago it started switching off if I pressed the back key and I would have to keep pressing it to get it switched back on.

It stopped charging in December. I got a new battery and charger and it worked again. Happened again 3 weeks ago. I got another new battery and worked again although takes ages to charge. It happened again on Monday. Battery works in different phone, charger works. Phone just won’t go on. It goes to the Samsung Galaxy Screen then just cuts back off as though battery is dead. Tried a different battery and that doesn’t work either. I’ve backed up my pictures but I’ll lose everything else if I can’t get it on. — Roseann

Solution: Hi Roseann. The daily wear and tear for 2 years may have finally taken its toll on some components. The first thing that you can do is to try to see if your phone can be booted to other modes (recovery, download/Odin, safe mode). If the remains unresponsive, you can assume that there’s a hardware failure. Make sure that you have it checked or repaired.

To boot in recovery mode, simply follow these steps:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.

Restarting the phone in download mode is similar to booting in recovery mode. Simply press and hold Power, Home and Volume Down buttons.

Now, safe mode is a special boot environment that allows a user to do some diagnostics. It is in fact a diagnostic environment to see if the phone is having some software issues. It’s a good way to see if your phone will still respond to hardware button combinations. Booting in Safe mode can be done by doing the following:

  • Turn the device off completely.
  • Press and hold the Power button.
  • Once the Samsung Galaxy S4 logo appears on the screen, release the Power button.
  • As soon as you release the Power button, press and hold the Volume Down key.
  • Continue holding the Volume Down key until the phone has completed the reboot process.
  • If you can read ‘Safe Mode‘ at the bottom left corner of the screen, release the Volume Down key.  Otherwise, repeat the process until you can boot the phone to Safe Mode.

Problem #5: Galaxy S4 reboot issue after updating to Lollipop

I have just upgraded my OS from Kit Kat to Lollipop. The installation process went well and the phone seemed to be working fine for about half an hour and then it randomly just switched off without warning and when I try to turn it back on it will show the black Samsung GT screen for 2 seconds then turn off again repeatedly. The only way to get it switch back on for good is to wait for approximately 5 minutes before turning it back on and then it will work well for a few minutes and turn off and then its a repeat of the cycle.

I have tried another battery but it makes no difference. While this is all happening, the phone still charges normally, just won’t turn on when its switched off by itself even whilst charging. Please help. — Shauna

Solution: Hi Shauna. App- and firmware-related problems following an OS upgrade may be fixed by wiping the cache partition and doing a factory reset. Make sure that you do both in that order. If wiping the cache won’t fix the reboot issue, don’t hesitate to do a factory reset. Be sure not to forget to create a backup of your personal data before you proceed.

Problem #6: Galaxy S4 camera not working due to insufficient storage

Good afternoon saw your article – How To Fix Common Samsung Galaxy S4 Problems and Errors- online. It’s very informative. But I was not able to find solution to my problem. I am using a Samsung Galaxy S4 Mini. I just bought it. The phone has internal storage of 32Gb and RAM of 1.5Gb.

The issue am having with it is that whenever am trying to use camera or receive files it will say “The phone storage does not have enough space.” I was surprised and confused. When I checked the “storage” under “settings” it showed “Total internal storage: 32.00GB.”

“Available 31.99GB.” So I don’t know why it is saying not enough space when I still have 31.99GB free in the internal storage. But, I discovered something when I checked under “My Files” it showed “Phone Storage” as “Total Space: 12.15MB” and “Available: 1.7MB.” This shows that truly “The phone storage does not have enough space.” My further check made me to realize that all of my few media are under “My Files” which is a folder inside “RAM”. My problem is that how can I move my files to the “Internal Storage” of 32GB, that is still 31.99GB free. I anticipate your informative response sir. Please try to understand and help me to fix my issue. — Akinola

Solution: Hi Akinola. Let’s make things clearer first. A Galaxy S4 mini can have two memory devices — the primary storage and the secondary storage. The primary storage is the internal Nandroid storage device that comes with the phone. According to official Samsung technical specification page for this device, the primary storage can only have either a maximum capacity of either 8GB or 16 GB. This total internal memory capacity can further be reduced after the operating system and apps are installed. Depending on your carrier’s firmware version, the volume of your personal data (photos, videos, etc) and the number of apps installed, your phone’s current primary storage may no longer be enough to allow the camera to operate.

The “internal storage of 32Gb” you’re talking about must be the secondary storage device you inserted, also known as SD card. We suggest that you try to move the files and some apps from your primary storage to the SD card to allow the camera to work. Keep in mind that some camera features like Burst Shots will only be saved to the primary storage device. If you are fond of taking burst shots, make sure that you have plenty of primary storage device space left.

Now, if you want to use the secondary storage device for photos taken by your phone’s camera, you must first change a setting to do that. Here’s how:

  • Open the Camera app.
  • Tap Settings (the little gear icon)
  • Tap Settings.
  • Tap Settings tab.
  • Tap Storage.
  • Tap Memory card
