How to transfer files from a Galaxy S7 to Mac using Samsung Smart Switch [tutorial], other issues

Hello Android community! Today we address a question that some Android users may be having: how to move files from their #GalaxyS7 device to a Mac. Although there’s just a small fraction Galaxy owners who may want to transfer data to their Mac, we also realize that there’s no readily available literature that provides a direct answer on what needs to be done. This is why we dedicate a third of this post to providing the steps to do this procedure successfully. We also answer two other issues that some others users may encounter. We hope you’ll find our solutions helpful.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem 1: How to transfer files from a Galaxy S7 to Mac

Hi. I have a Galaxy S7 Edge with a 32GB micro SD card. The card is almost full and thus I would like to backup the contents of the card to my Mac and then transfer those back onto a new, larger micro SD card. However, when attempting to connect over USB (the cable supplied originally with the S7 Edge), the Mac is unable to connect. “Android File Transfer” tells me “Could not connect to device” and “Try reconnecting or restarting your device.”This persists after reconnection of the USB cable, and after power cycling the S7 device. I’ve also confirmed that when I pull down the ‘window shade’ on the S7, there is an update stating “Android System” and it’s set to “File Transfer.”

Note I’ve tried other settings and those aren’t working either. I’ve also tried ‘Coolmuster Android Assistant for Mac’ and that doesn’t seem to work either. Several google searches leave me still without any solution to this problem. I’m hoping you may have some insight? I would really appreciate any suggestions you might have. — Chris.Ambrozic

Solution: Hi Chris. Computers like PCs or Macs generally are equipped with a suite of USB software called drivers to allow them to recognize connections from another device like an Android smartphone. In most cases, these USB drivers are developed by the operating system manufacturers such as Microsoft for Windows-based PCs and Apple for Macs. These drivers, just like any software or operating system sometimes need updates. So, if your Mac has not been updated lately and there’s a pending update for its Mac OS, make sure to install it first before attempting to connect your S7 to it again. If your Mac already runs that latest available update at this time, you can do further troubleshooting by following the steps below.

How to use Smart Switch for to transfer files from Samsung to Mac OS

The easiest way to ensure that your Mac recognizes your Galaxy S7 is by using the Samsung Smart Switch application. It’s an official app from Samsung designed to allow you to seamlessly transfer data between your Samsung device and your computer.

Step 1: Verify if your Mac is compatible with Smart Switch application

Your Mac needs to meet some minimum requirements in order for Smart Switch app to work. Below are the minimum requirements:

  • Operating System: Mac OS X® 10.6 or later.
  • CPU: Intel Core 2 Duo 2.0 GHz or higher.
  • RAM: 1GB or higher.
  • Screen resolution: 1280 x 800.
  • Android file transfer application installed on your computer.

Step 2: Ensure that you have Android File Transfer application installed in your Mac

You mentioned Android File Transfer application so we assume that’s it’s already installed. However, we want you to uninstall, then reinstall it just in case.

To reinstall Android File Transfer application, follow these steps:

  1. After uninstalling Android File Transfer application, download the app again by following this link.
  2. Open androidfiletransfer.dmg.
  3. Drag Android File Transfer to Applications folder.

Step 3: Use Smart Switch to transfer files from your Samsung Galaxy S7 to Mac

If your Mac meets all the requirements above, you can then install the Smart Switch application. Once you’ve finished installing Smart Switch, follow the steps below in order to transfer your files to your Mac:

  1. Connect your Galaxy S7 device to your Mac via USB cable.
  2. Open Smart Switch application in your Mac.
  3. If it says that your phone is locked, simply unlock the screen of your Galaxy S7.
  4. Wait for Smart Switch to recognize that the phone has been unlocked. This can take a few moments.
  5. Click on the name of your phone (Samsung Galaxy S7).
  6. Click on the memory where your files are located.
  7. A screen should open showing you the folders in the selected storage device. Choose Card to open folders in the SD card.
  8. If you want to move a folder or file to your Mac, simply highlight it then drag it to the folder location you want.

Step 4: Wipe your Mac and reinstall clean Mac OS

If your Mac remains problematic and won’t allow you to install Smart Switch for some reason, or if Smart Switch won’t work as expected after installing it, consider wiping your computer and reinstalling a clean version of its operating system.

Problem 2: Galaxy S7 edge keeps freezing, stops responding when in normal mode

Hey! My Samsung S7 edge suddenly started to freeze. Once it froze, it didn’t respond to anything. Not even the “power button + volume down button” or “power button + volume up + home button.”I went to the closest technician, and they backed up my data, restored firmware and gave my phone back. Once i got home, deleted almost every app on the phone, since i thought it was somehow related to the crashing. The phone somehow still acted strange by crashing and freezing, but the “volume down + power button” did the trick. Today it froze, so i booted it in safe mode. Everything was okay for 10 minutes, but then when i decided to power it up back to normal, it restarted and froze again, unresponsibly to anything. Is there anything i can do with it? Because the local technician said that they can do another firmware restore, but since i still have the problem after it it feels unnecessary. Best regards! — Mantas Gusmantas

Solution: Hi Mantas. If the phone was working normally when it was running in safe mode, then a bad third party app is most probably to blame. Observing the phone for 10 minutes though is not long enough to allow you to confirm that. Try restarting the device again to safe mode for at least 24 hours. In this mode, only pre-installed apps should be running so if the phone runs perfectly fine throughout the observation period, you can bet a third party app is to blame.

To know which app is causing the trouble, you’ll need to use the method of elimination. Here’s how:

  1. Uninstall a third party app. Remove the most recently installed app first. If you can still remember what app you install right  before the phone started to freezing up, remove that app first.
  2. After you uninstall an app, check if the problem is still present by using the phone as usual for up to 10 minutes. If it works fine without the hiccup, then the newly uninstalled app is probably the one causing it.
  3. If the problem returns, uninstall another third party app.
  4. Repeat step number 2.
  5. Do Steps 1-3 until you’ve identified the source of the bug.

Problem 3: Galaxy S7 missing Software update option under Settings

So when I try to update my S7 edge it fails to update everytime. And when I go to applications in my setting and look for the software update app it isn’t there so the only way I can access it is when the notification pops up at the top and if I hold down on the notification it brings me to the disable, force stop options and the apps data but I’m not able to press force stop or disable like it said in your article so what do I do? The version it says it is is 2.0.22-0. — Kammy

Solution: Hi Kammy. It’s a bit suspicious that you can’t find the Software update option under Settings app. If this Galaxy S7 edge was provided by your carrier, make sure to contact them to ask if they intentionally removed the Software update option. In a lot carrier-provided S7s we examined, software update should still be available. It definitely is present in international versions and those models that are not locked to carriers.

If your carrier will say that software update option should be present under Settings, then something must have removed it. We’re not aware of any malware that may do such but there’s always a chance that it can happen. We don’t know enough about your phone history to be of help in giving you an accurate answer.

To be on the safe side, you can try to perform a factory reset to see if the Software update option will resurface afterwards. Here’s how to do that:

  1. Create a backup of your important files such as photos, videos, etc.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option Yes — delete all user data using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Galaxy S7 screen stays black but remains responsive, monitor is not working, other issues

Hello Android fans! Today, we answer some questions posed by some members of our community regarding their #GalaxyS7 having screen problems. We also answer a common question by those who crossed to another network — why their phones no longer installs system updates. We hope that our answers will be helpful for those experiencing similar cases.

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.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 screen is unresponsive, keeps freezing

My Galaxy S7 is only 11 months old. Full story: Dropped the phone about 8 months ago, cracked on top edge and back glass but functional and didn’t bother me. It worked fine. About 6 weeks ago, phone wa caught in electric recliner chair and pretty much destroyed the front glass and no readable display. It did work using Bluetooth. I could make phone calls from car. I had the screen, LCD and DIGITIZER and BACK of phone as it was cracked, also replaced at a 3rd party repair shop I had used before for an iPhone screen. The repair seemed great for about 4 weeks. Then the phone started glitching. Part of the screen is unresponsive and froze. and within 2 hours the whole right side of screen was frozen. Multiple reboots ended up with grey static screen on right side and left side seemed to work normally but could not scroll left/right to make it even usable.

I tried everything I could find including multiple Factory reboots and pulling/replacing the SIM card. It is still showing all grey on right. Had the repair place replace the screen a 2nd time – they say it worked for 20 minutes then went back to the same problem. I do not think they replaced digitizer the 2nd time.

Contacted Samsung. There is no local service place near me so I would need to mail it in for review. I highly doubt they will cover under warranty since it was repaired elsewhere . I have read that since factory reboot didn’t fix it this is a hardware issue. What other hardware could be the cause? Thanks much. — Leo Stringer

Solution: Hi Leo. Firstly, your phone has been battered badly and was repaired by a third party shop so sending it to Samsung service center is really not option. They’ll reject your request for repair outright, even if you’ll pay them for it.

Secondly, we don’t think there’s any other issue with the phone but if the repair shop did the screen replacement properly using compatible components, there’s a chance the problem may be the graphics chip. This means that part of the hardware diagnostics should involve checking if the graphics card is still working or not. If it’s not, it may need to be replaced. Otherwise, a full motherboard replacement may be attempted if screen replacement won’t fix your issue at all.

Thirdly, stop wasting your time doing software solutions. There’s no amount of factory resets and software modifications that you can do to fix a physically broken device.

Problem 2: Unlocked Galaxy S7 won’t install software update

I had my Samsung S7 unlocked by a third party; it was done successfully. When we tried to log in using the PINI had set, it wouldn’t verify and kept on asking to enter the PIN. We had to factory reset. It seemed that the tech guy modify my operating system in someway. I kept getting notification that “unauthorized actions has been detected, restart your phone to undo these actions.” Furthermore, when I tried to do a software update I get this message “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center. Nothing works. Please help. Thank you. — Chris

Solution: Hi Chris. By unlocking we assume that you meant changing some network parameters to allow your device to connect to another network. This means that your phone should now be able to send and receive SMS/MMS and be able to send and receive calls using a network other than the one the phone was originally built for. Also known as network unlocking, the procedure does not usually touch the core operating system files of GSM phones to cause drastic changes. The case of CDMA phones though may be a little different and may, in fact, require operating system-level changes. Since you did not provide enough information, we can’t say what exactly is happening but the error message appears to be an indicator that your phone’s software has been modified. Devices with modified software are relatively unsecured, depending on the modifications done so if you’re interested to know about the risks involved, you should talk to the person who did the software modification in the first place.

Also, keep in mind that unlocked devices does not necessarily mean that the software has been completely changed to that of the version of the current carrier you’re using. For example, a Verizon S7 can’t have a T-Mobile software at all. The Verizon software continues to run everytime you use the device although some of its network parameters may have been changed to allow you to use it in T-Mobile network. This also means that you won’t be able to update the software at all since the update files a T-Mobile network will only be available for T-Mobile devices. If you want to run an updated Verizon software, the phone’s software needs to be flashed.

To know more about flashing, do more research about it.

Problem 3: Galaxy S7 screen stays black but remains responsive, monitor is not working

Hi. So i am having an issue with my phone’s screen staying black. it will recognize me touching the screen and everything but it will not light up for me to see anything. i have tried all the reset options and booting it in safe mode and recovery mode and nothing. When i have noticed that when i turn it on it very briefly flashes dark then turns black again. Any ideas? i’m very stumped on this. Thanks. — Bill

Solution: Hi Bill. We think the phone’s monitor has malfunctioned. Your phone’s display assembly is composed of three major components — monitor, digitizer, and flex cable. The monitor is the part that shows images you see on the screen. On top of the monitor is a thin layer of touch sensor called the digitizer that converts finger touches into digital signals. These signals are then transmitted to the motherboard to be processed.

Verify if software glitch is to blame by booting to Recovery Mode

If the phone’s screen remains black but still appears to respond to your touches when you hit the right spot, that’s a clear hint that only the monitor has gone bad. In other words, the digitizer can still receive your input but the monitor is unable to display the appropriate images that should be on the screen. A situation like this is usually the result of physical damage. Only very rarely do we encounter cases wherein a software glitch or an app is to blame for the monitor to fail. And even if there’s a software-related bug causing it to fail anyhow, a master reset should be able to fix it. To do that, follow these steps:

  1. Turn off your Samsung Galaxy S7. if you can’t turn it off normally, wait until the battery is drained so the device shuts down on its own.
  2. Charge the phone for at least 30 minutes.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option Yes — delete all user data using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Remember, you can’t perform a master reset if the phone is ON. You must turn it off first in order for you to boot the device successfully to Recovery Mode.

Send the phone in for repair or replacement

The only other step that you can do to fix this issue is by allowing a professional help you. That is, if the nothing changes after attempting to boot the device to Recovery Mode, or if master reset won’t help at all. As mentioned above, monitor failure is almost always a product of physical damage. If you dropped your phone or exposed it to water/elements before noticing the problem, there’s no amount of software tweaks that you can do to fix it. A physically broken component in this situation can only be addressed by repair or replacement. We know you want to think that there must be something that can be done but that’s the reality. 

Some advanced users may attempt to replace the damaged component by themselves. Part replacement is okay as long as you know what to do exactly. You don’t want to attempt it if you don’t have the minimum knowledge and tools to perform the task though. If you think you can handle the screen replacement yourself, do some research and look for a good guide on how to do it. Our blog does not support hardware issues.

Galaxy S7 keeps rebooting by itself, won’t load operating system normally, other issues

As expected, more and more #GalaxyS7 users are now sending us distress signals. We’re not saying that S7 devices have suddenly become problematic. No. What we mean is that at this time, it’s expected that many S7 and S7 edge devices are now beyond their prime of one year, and thus a lot of power- and boot-related problems are starting to show up. As usual, this post aims to address some of these issues. We hope you’ll find it useful.

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.

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.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 freezing issue, screen turns black on its own, battery drains fast

Hi. Love(d) my Galaxy S7, but suddenly for no apparent reason it would freeze, (battery levels from 95% to 45%) and then go to a black screen (think it turns itself off) after about 30 seconds. I try hard boots, soft boots … everything I can think of and still nothing at all. The first time it happened, I was about to take it to the store, but plugged it in just to try once more, and it started charging, with the picture of the big battery showing. Since then, I realize that if I leave it for awhile and let the battery drain to zero (which makes no sense since it looks like it is powered off) I can then recharge and turn it on no problem. If I try to recharge before the battery it drained, it shows nothing. To did a factory reset after the first time, still it happened again.  It has now happened 5 times! I am only lucky I have an older Nexus phone that I can swap the sim card into so I am not without my phone while it drains the battery. Any ideas??? — MaryAnn

Solution: Hi MaryAnn. If factory reset, which is the most drastic troubleshooting that you can do in this case, did not change anything at all, there are only two possible reasons for the problem.

One is the possibility of a bad third party app you keep reinstalling after a factory reset. Poorly coded apps don’t usually provide obvious hints that they’re affecting other apps or services. To check if this is the case, we suggest that you restart the phone to safe mode and observe the phone for at least 24 hours, or until the battery goes down from 100% to 0%. Safe mode will prevent third party apps and services from running so it’s a good way to test our theory out.

If the problem won’t occur while the device is in safe mode, you can bet our suspicion is on target. Here are the steps on how to restart your phone to safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If the issue continues while the phone is on safe mode, then it means bad hardware is to blame. It can be a malfunctioning battery, an error with the power management IC, or other unknown hardware fault. To fix the issue, contact Samsung and let them repair or replace it.

Problem 2: Galaxy S7 keeps rebooting by itself, won’t load operating system normally

I have a Galaxy S7 and all it wants to do is reboot itself over and over again and I’ve done everything in the troubleshooting, that’s posted on line to help fix the issue. Well, my phone will not respond to anything. I’ve done the manufacturer reset, I’ve cleared the cache. it just keeps turning itself off, and then rebooting and then when the Samsung logo pulls up and you hear the music from T-Mobile then it makes a low buzzing sound. It would do this but it would only take maybe an hour or to stop rebooting and everything will be back to normal. now it takes until the phone dies. But now it will die and then I will charge it all the way and turn it back on and then it’s goes back to doing what it was doing before was rebooting itself over and over again. And turn it in and get a new phone cuz it feels like it’s just shot? — Kelly

Solution: Hi Kelly. There are numerous factors that can come at play for an issue like this including a bad third party, poor app/firmware coding, or malfunctioning hardware. We don’t know the full history of your device so we can’t tell you what may be happening at this time. However, if you haven’t tried wiping it off by doing a factory reset yet, we suggest that you do it now. Here are the steps to do that:

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

Keep in mind that factory reset can only do so much. In essence, it’s a software solution and can only fix issues caused by software-related problems. If nothing change after you’ve factory reset the device, or if you can’t finish the entire master reset procedure at all to begin with, you can assume that there’s a hardware malfunction somewhere. In a lot of similar situations, broken power management IC is to blame. This means that you’ll need a trained technician to take a look at the device to fix it. For this reason, you’ll want to contact Samsung for support.

Problem 3: Galaxy S7 edge won’t turn on unless plugged in to charger

My S7 Edge turned off and wont turn back on till full battery drains out. Then I need to plugin the charger & it will show charging. After this I can start the mobile but within minutes it will again make a cracking noise or freeze the screen and switch off. I have tried all the methods, safe mode, recovery mode, master reset but nothing is working. Earlier it use to restart & would work for few hours or a day and then same. It is out of warranty. — Asif Sayed

Solution: Hi Asif. Try to see if reflashing the bootloader will make a difference. Bootloader runs a different code (non-Android) that prepares the system before Android is loaded. Usually, if a bootloader becomes corrupted, it can make the phone get stuck in a bootloop, just like what’s happening with your device right now. Just like other solutions you’ve already tried, it only affects the software aspect of your phone. If it won’t work, or if you won’t be able to complete the flashing procedure at all, that means that the issue is being caused by a bad hardware. For this, you want to have the phone repaired or replaced.

For reference, below are the steps on how to flash a bootloader of a Samsung device, like your Galaxy S7 edge. Exact steps for your particular phone model may be slightly different from the steps below so be sure to do some research. Our guide is for demonstration purposes only.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

What to do if Galaxy S7 freezes after after installing Nougat update, other issues

Hello and welcome to another #GalaxyS7 troubleshooting article. Our focus for today’s post is to address the common freezing issue that sometimes occur after installing an Android update. We hope you’ll get something useful in this post.

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.

Problem 1: What to do if Galaxy S7 freezes after after installing Nougat update, keeps freezing in Recovery Mode

Hi. I recently installed an update for Nougat that messed up my S7. It started freezing in a few seconds after reboot. I’ve tried factory reset, but the process was interrupted by this freezing and rebooting thing. Tried cache reset in recovery mode, still nothing. Also tried factory reset inside recovery mode, no avail. What bugs me is that this freezing happens every inside recovery mode: I have just a few seconds to select the options before it freezes. In recovery mode, however, it does not reboot automatically. Tried to flash a new stock ROM with Odin, but the problem persists. Is it a hardware issue? And if it is, how can an update cause this? Thanks. — Candian

Solution: Hi Candian. Updates can sometimes result to a hardware issue if the storage device becomes corrupted for good. This sometimes occur if update is interrupted for some reason. This is a rare occurrence though and Samsung Galaxy S7 storage device can appear healthy even if one intentionally disrupt the update, for instance, by turning off the phone. Permanent hardware damage can happen at random so we hope that this is not your case. Since the phone won’t allow you to complete a factory reset in Recovery Mode, we suggest that you attempt to reflash the bootloader instead. If you can do it successfully, there’s a chance that you’ll be able to boot the phone back to Recovery Mode and perform a factory reset. If it won’t help at all, you should consider calling Samsung so they can take a look at the hardware.

Below are the steps on how to flash a bootloader. It’s basically similar to flashing a firmware with the difference being to change the bootloader software only and not the operating system. Exact steps may be slightly different from our guide below so be sure to check other guides for the correct format.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 2: Galaxy S7 edge won’t turn on

I own a S7 edge. I have been having this issue since 2 weeks ago when i was charging my phone and all of a sudden the always on display went black and screen frozen with red led light on even after i unplugged the charger. I have tried rebooting by using volume down and power button hold as well as volume up + power + home button but the phone is not responding to my command. Initially i was thinking of waiting for the phone to drain out of battery as i think that it was a system crashed but the waiting was too long. I need help.. Please help me!!! Thank you and your help will be much appreciated. — Eugene

Solution: Hi Eugene. You only have a very limited set of troubleshooting that you can do for this issue since the phone does not charge or power on anymore.

Use different set of charging cable and adapter

A good first thing that you must do is to ensure that the charging accessories — USB charging cable and adapter — are not the problem. Make sure that you use a different USB cable and adapter so you’ll know if the main reason for the problem is not due to faulty accessories.

If you tend to charge in a favorite outlet in your house, consider plugging in the adapter to another outlet in the house as well.

Check charging port

One of the easily damaged components in any smartphone is the charging port. Everyone uses it for charging and more moving data and if one is not careful, the pins can be damaged fairly easily. If possible, try to use a magnifying tool to inspect the inside of the port. If a metal contact is bent or out of place, your phone may not charge properly or at all.

Sometimes, lint or dirt may accumulate inside the port as well, blocking the cable from making contact with the metal contacts. This can result to erratic charging. If you see some dirt or foreign object inside, try to use a can of compressed air to dislodge it. Avoid sticking something in the port to prevent damaging the pins.

Boot the phone to different boot modes

If your phone was not misused — dropped, wet, or exposed to elements (water, heat, cold) — and the issue simply occurred out of the blue, you must try to see if you can turn the phone back on to alternate modes. These modes run different codes and does not need Android. If your phone turns on fine when in any or all of these modes, the most likely problem is  Android-related. This gives you a chance to fix the problem by doing a factory reset or flashing.

Below are the steps on how to boot your phone to alternate modes:

Boot in Recovery mode

  1. Turn the phone off. This is important. You won’t be able to boot to Recovery Mode when the phone is off in the first place. If the charging light is lit, or if the phone still makes sound or vibrate notifications, it must be on. You must wait until the phone shuts down on its own if you can’t power it down normally.
  2. Charge the phone for at least 30 minutes.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode

  1. Turn the phone off. This is important. You won’t be able to boot to Recovery Mode when the phone is off in the first place. If the charging light is lit, or if the phone still makes sound or vibrate notifications, it must be on. You must wait until the phone shuts down on its own if you can’t power it down normally.
  2. Charge the phone for at least 30 minutes.
  3. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  4. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  5. Wait until the Download screen appears.
  6. 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.
  7. Use Google to look for a guide on how to do it.

Send it in for repair or replacement

If your phone won’t turn on at all, nor would it boot to any of the modes above, that’s a sign that there must be something wrong with the hardware. You should contact Samsung so it can be repaired or replaced.

Problem 3: Galaxy S7 edge screen is black, won’t turn on

My Samsung S7 edge just blacked out. I’ve tried to push all 4 buttons at the same time as well as different combination of buttons but my screen is still blank and does not turn on or show the galaxy loading logo. When I press the home button occasionally flashes the side touch buttons and also it occasionally shows blush flash at the top. But my screen is still blacked out. It was also put on charge so I know it has full battery. Also I don’t know what my andriod version is and as my phone does switch on I can’t check. — Atika.sundus

Solution: Hi Atika. If the phone still charges fine and appears to power on (as indicated by side touch buttons still working), the problem must be isolated to the screen only. This means that the phone is not dead at all but the screen probably is.

Smartphone screens are usually robust and can continue running for years at a stretch. We seldom encounter Samsung screens going bust on their own. In most cases, screens only stopped working after the phone has sustained physical damage. If your phone was dropped or has become problematic after it got wet, don’t waste your time looking for software solutions. You should instead focus your time and effort in having it checked by a technician. Unnecessary shock and/or water can lead to all sorts of problems and you can’t make them go away by tweaking the software.

However, if nothing of these sort happened and the phone simply loses its ability to display images suddenly, it’s possible that software may be to blame. Consider booting it to safe mode first and see what happens. Safe mode blocks third party apps and services so if the screen returns, a content must be to blame. To boot to safe mode, follow these steps:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. 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.

Factory reset via Recovery Mode

Should nothing change when the phone is in safe mode, or if you can’t boot to safe mode at all, you should then try to see if you can get the phone to boot to Recovery Mode. If the phone goes to Recovery Mode, which means that it works, the most likely reason for the trouble is software-related. Make sure that you do a factory reset.

On the other hand, if the problem stays regardless of the steps you tried, that’s a clear sign that it must have sustained damage for some reason. You should have the hardware checked.

Galaxy S7 keeps crashing and won’t boot to regular mode, backup via Smart Switch, other issues

Our today’s #GalaxyS7 troubleshooting covers power- and boot-related problems. These problems are some of the common issues that a lot of users encounter so hopefully, this article will not only help those mentioned below but also others who may have similar experiences.

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.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 edge keeps freezing and screen keeps blacking out, creating backup via Smart Switch

I have a Samsung S7 edge & have had it for over a year. A couple of days ago my screen froze then the black screen appeared. It would not respond to anything. It had 3% left of battery life, so I put it on charge. Nothing happened on the screen at all. I Googled & followed your steps of holding the volume down & power button & it worked. I had my phone back for almost a day.

Then the next night it let me know I had 15% battery life then my screen froze with a couple of black lines on the page I was reading, then the screen went black, but the blue LED light would dim then get bright. I followed your advice, but nothing was working. I left the phone alone for a couple of hours, then the blue light went out. We guessed the battery went flat. As we were away, I waited to charge it until we got home. We arrived home & I placed it on charge. The battery symbol appeared & it started charging. It got to 69% so hubby tried the power button & the volume down button & it came on. I entered my password but then it froze. I kept pressing the power & volume buttons then it allowed me to enter my password & my home screen appeared. My biggest fear is I don’t know if all my photos are saved on the memory card & I have really important emails. Hubby was trying to see I had saved my photo’s but it froze again & the screen went black. Is all of this going to erase any of my personal stuff on the phone? Can any of my stuff be saved? Can it be fixed? — Haidi

Solution: Hi Haidi. The random reboot of the system may eventually take a toll on the memory and possibly corrupt it. We have no way of knowing though when this will happen, if at all. The best thing that you can do is to make use of the opportunity, when the phone appears stable enough to allow you to create a backup. We suggest that you use Samsung Smart Switch during the time when your S7 works normally to move your files to your computer. Here’s how:

  1. Install Smart Switch app in your computer.
  2. Open the Smart Switch app on your PC or Mac.
  3. Connect your Android device to your computer via USB cable.
  4. Make sure your phone is unlocked.
  5. On the Smart Switch app click on MORE at the top right.
  6. Click Preferences.
  7. Click Backup items tab. In this tab, you will be able to customize what items to copy and keep as back up. All items are selected by default by if you want to speed up the copying process, you may want to select the important boxes only.
  8. Once you’ve selected what items to include in your backup, click OK. Otherwise, simply click Cancel.
  9. Click Backup.
  10. Tap Allow on your phone if Smart Switch asks for permission.
  11. Once the backup is complete, you get a breakdown of all the data that was successfully backed up. Click OK to finish.

If you don’t have a computer to install Smart Switch to, make sure that you turn on Sync by pulling down the notification bar and tapping the Sync icon. Then, go under Settings>Cloud and accounts and make sure that either Google and/or Samsung account sync options (Backup settings or Auto back up) are enabled to let the phone upload copies of your photos automatically to the cloud. If you have lots of photos, be sure to upload only when you are connected to a strong wifi network with good internet connection speed to avoid incurring data charges. Once you’ve backed your photos up, you can then log in to your Google or Samsung accounts in another device like a computer to access them. Google and Samsung free cloud accounts are limited so if you have several GBs of photos and videos, you may run the risk of running out of cloud storage space. If you want, you can talk to their customer service to add more storage.

For your emails, they should be safe as long as you have copies of them in your email provider’s remote servers. However, if you set your email account to POP/POP3 during setup, your emails must only be kept locally (in your phone’s memory). This means that if the time will come that your phone will become totally dead and hence the memory’s inaccessible, you’ll also lose your emails. To check if your emails are saved in your email provider’s computers, try to log in to its webmail version in a computer. If you’re referring to your work email, be sure to talk to your IT guys to know more about it.

Now, all these freezing and screen blacking out issues can be signs of a bad hardware like a failing battery. To check if that’s the case, we recommend that you factory reset the device and see. Be sure to only do the said reset after you’ve created a backup of your important files.

To factory reset your device, kindly do these steps:

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

Remember, factory reset returns all software settings back to their known working defaults. At this state, no bugs should be present including ones that can affect the battery or other phone functions. If your S7 still continues to act erratically after a factory reset though, that means bad hardware is behind it. In this case, you must contact Samsung for repair or replacement.

Problem 2: Galaxy S7 keeps crashing and won’t boot to regular mode

So I have a Samsung Galaxy S7. One day it crashed and froze on the home screen and overheated and I left it and did a forced reset. After this the device would switch on and get stuck on the loading screen. I loaded it in safe mode, but it continued to crash. Afterwards I backed up my documents and did a factory reset and the problem has continued. It will load first time to the home screen and cut out after a couple of mins and reset but gets stuck in the load screen and gets very hot. It then stays like this until the battery dies again. I am very stuck as to what I can do with it? Do you have any advice? — Daryl

Solution: Hi Daryl. Since factory reset did not do anything at all, the only other software troubleshooting that you can try at this time is to reflash the bootloader. This will return this important piece of code back to its default settings and hopefully allow the phone to boot back up normally. Here’s how it’s done:

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Remember, there’s no universal flashing guide. The exact steps for your particular phone model may be slightly different from the steps above so be sure to check other guides. The steps above are only for demonstration purposes only. Also, flashing requires a computer with the right Odin program to do.

Problem 3: Galaxy S7 won’t turn on

Last month, my phone started to power off in the middle of texting, and phone conversations. I called support tech…they did a diagnostic test, and said battery was good, and it was charged. Also, I took it in to an AT&T store, and was told that battery, and all else seemed good. One day the phone powered off, and never powered on again. I need to retrieve all my files, and data. Please help me. Thanks. — Ryan

Solution: Hi Ryan. Access to your phone’s storage device is only possible when the phone is powered on and the touchscreen is working to allow a second device like a computer to move files. If your phone has become totally dead, you’ll need to find a way to fix that first. Kindly check this link and follow our suggestions for Pinkiegrl17.

Galaxy S7 edge LCD replacement due to flickering screen issue, other issues

Hello Android fans! Welcome back to our new #GalaxyS7 post. Our troubleshooting article today covers screen issues and what to do with them. We hope to enlighten you regarding this type of issue.

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.

Problem 1: Galaxy S7 edge LCD replacement due to flickering screen issue

S7 edge screen flickers and I want to replace the LCD and digitizer myself but when I look for the replacement I’m confused as to whether to replace outer screen and digitizer or the inner LCD. Is there a difference or what is the correct part to replace to correct the flickering issue? Any help would be greatly appreciated. — Philip W.

Solution: Hi Philip. If you find your phone’s screen flickering, there are a number of possible reasons for it:

  • incompatible apps
  • unknown software glitch
  • a defective monitor/LCD
  • a broken flex cable
  • possible problem with graphics chip
  • unknown motherboard issue

Try software troubleshooting first

In order to identify the cause of the problem, you must follow a set of troubleshooting steps. Ideally, you’re supposed to start by doing software troubleshooting, especially factory reset. If you’ve already done that, or if the screen flickering issue was a product of misuse (accidental drop, physical impact, water damage), you can skip software troubleshooting and should instead let a professional check the hardware. Since you seemed intent on doing the replacement yourself, we assume that you’ve already isolated the issue to a bad screen assembly. If the screen continues to flicker after after replacing a part or the entire assembly, you may have to replace the entire motherboard.

Symptoms of bad screen issue

A Galaxy S7’s screen assembly is composed of three major parts — digitizer, monitor, and flex cable. The digitizer is a thin layer of transparent sensor that converts analog finger touches into digital signals. These converted data are then transmitted to the motherboard by the flex cable

The images you see are made possible by the monitor, or what you call LCD. A broken monitor manifests in a number of ways including discoloration, lines (vertical or horizontal), flickers, or just plain black screen. The same symptoms can be displayed by a malfunctioning flex cable and graphics chip though so if the problem won’t go away replacing the LCD/monitor, you should proceed with flex cable replacement. If that won’t work still, go ahead with motherboard replacement.

Replace screen assembly instead of a part

If possible, we recommend that you simply replace the entire screen assembly instead of doing it piecemeal. If this is your first to replace a screen, there’s a chance that you may end up damaging the digitizer since it’s connected to the top of the monitor. If you think you can manage it though, go ahead with monitor replacement.

Problem 2: Galaxy S7 keeps freezing, reboots randomly

My Galaxy Samsung S7 keeps freezing. When I restart it, it works for like minute or so and freezes again. Or while I am doing something on the phone it just reboots itself and as it turns on. it will reboot again and again and suddenly it just stay on black blank screen with a blue light lit up. When I press Volume Down and Home key along with key simultaneously it comes on. Once it comes the cycle continues all over. I had the phone factory reset and flashed. Still having the same problem. — Luis

Solution: Hi Luis. An issue like yours can have a few causes including an incompatible/malicious app, bad software glitch, malfunctioning battery, or just plain bad motherboard. Like troubleshooting the issue above, you must start with software solutions.

Observe the phone in safe mode

The first thing that you want to do is to check what happens when the device is booted to safe mode. Freezing symptom can be due to low memory caused by a lot of third party apps and services hogging up resources. To put a check on all third party apps, you must attempt to put it in safe mode. We don’t know if it’s possible but it’s worth a try. Here’s how to do it:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. Observe the phone for 24 hours to see if there’s any difference in terms of performance.

Remember, safe mode is not a solution but a way to an end. If your S7 works normally for a full day, without the symptoms you mention above, you should invest time and effort in eliminating problematic apps from the system. Only you can do this so if you have hundreds of apps installed, it may be a long process. Basically, what you need to do is to observe the phone for an hour after uninstalling an app. This will give you enough time to notice a difference. Do the same cycle until you notice that the symptoms are gone.

Reflash the bootloader

Sometimes, flashing the firmware can affect the bootloader as well, causing a device to be stuck in an issue called boot loop. Basically, a boot looping device can’t load Android at all and regularly goes into a loop when booting on. If the cause of such situation is a corrupted bootloader, reflashing the bootloader with the stock version should fix it.

Below are the general steps on how to reflash a bootloader of a Samsung device. Exact steps may vary a little so be sure to consult other guides for your particular model.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Replace the battery

Some freezing and random shut down issues can be one of the symptoms of a bad battery. Should the steps above, especially after reflashing the bootloader won’t work, you’re most likely looking at a hardware problem, with the least being a bad battery. If you can, make sure to replace the battery. However, if the phone is still under warranty, or if you don’t want to tinker with the hardware, have Samsung fix the issue for you.

Problem 3: Galaxy S7 screen won’t turn on, screen remains black

I put my T-Mobile Galaxy S7 on a table to charge. It was working fine. A little later I found my phone on the floor and the screen was stuck on black but notification lights were on and I could hear my phone powering on and hear vibration. I Google how to fix my problem and I found a forum that said to push the Volume Up button, the Power button and home button all at the same time until the little green reboot guy pops up. I never saw him pop up and now my phone wont even power on. — Ashley Pennington

Solution: Hi Ashley. There’s a difference between a phone not turning on issue and screen not turning on issue. Which one are you having? The first means that the phone is totally dead — no light and sound notifications, no vibration, or does not ring at all. The second means that only the screen is not working but the phone still powers on as manifested by sound and light notifications, vibration, or ringing during calls.

If your issue is similar to the second case, try to see if the problem is caused by a software problem. To do that, try to boot the phone to either Recovery Mode or Odin Mode and see if the screen works. If it remains black, or won’t boot to any of the modes at all, consider having the screen replaced.

Below are the steps on how to boot the phone to Recovery Mode or Odin Mode:

Boot in Recovery mode:

  1. Turn off the phone. If you can’t turn it off normally, let the battery drain and wait until the phone shuts down on its own.
  2. Charge the phone for at least 30 minutes.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. 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.
  6. Use Google to look for a guide on how to do it.

How to fix Galaxy S7 random restarts issue, other issues

Random restart problem can happen due to a lot of causes. Today, we address this issue as we’ve received a number of #GalaxyS7 users reporting it. We hope you’ll get something out of this material.

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.

Below are specific topics we’re bringing for you today:

Problem 1: How to fix Galaxy S7 random restarts issue, restarts on its own when using KnowRoaming SIM abroad

Samsung Galaxy S7 restarts over and over again ONLY when I’m overseas. I’m a flying crew and it happened twice in the span of 20 days. Once when I’m on the plane and once when I was in Jakarta. I tried several solutions but whenever I tried to connect myself to the internet (via WIFI or 4G), the phone just goes into an infinity loop (And at this point my keypad will be unusable for some reason). However when I arrive in my home country, my phone would miraculously be alright again. Note: I’m using a global SIM card called KnowRoaming whenever I’m overseas. — Aiden

Solution: Hi Aiden. Unlike other Android issues, it’s difficult to know what exactly is causing your problem since there’s a long list of possible reasons for it. A good thing to start doing first though is to check if the problem is being caused by the KnowRoaming SIM card. If your phone works normally fine when you’re back in your home country (and presumably using your local carrier’s SIM), it’s very likely that the KnowRoaming SIM card is interfering with the operating system causing it to behave erratically. You’ll most probably spending more effort in knowing this but we are almost positive that it has something to do with your third party SIM. otherwise, you can check the generic troubleshooting steps for standard random reboot issue below.

Install app and Android updates

Updates can contain fixes for known bugs so before you fly out again, be sure that your phone installs all available apps and Android updates. To check if your S7 has pending Android updates:

  1. Launch Settings app.
  2. Tap Software update.
  3. Tap Download updates manually to make the phone search for latest updates. We suggest that you enable Download updates automatically option so let your device receive updates on its own.

Poorly coded third party apps can also affect other apps so in order to minimize problems from them, make sure that they run their latest available versions. Updated apps tend to have fewer issues than outdated ones.

Uninstall or disable apps

The more apps are running at the same time, the more memory (RAM) is being used up. In older devices, the lesser RAM there is, the more that a device tends to become problematic. Some may crash, while others may slow down in terms of general performance. We haven’t noticed these RAM issues in Galaxy S7 devices running Marshmallow and Nougat though. Android is designed to manage RAM on-the-fly by automatically closing some apps if necesarry to free up RAM, but it wouldn’t hurt if you’ll help close some yourself. To do that, simply tap the Recent Apps button (the button at the left side of the Home button) and tap X on the app you want to close.

Better still, you can uninstall or disable apps you don’t regularly use. Remember, the less apps you have in the device, the fewer the chances of bugs from developing. Remove apps you haven’t used in a few weeks, or those new ones you may have installed prior to noticing the problem. One of them may be causing the issue.

Restart the device to safe mode

If you suspect that one of the downloaded apps is to blame, try restarting your phone to safe mode and observe it for a few hours or even days. Safe mode blocks third party apps and services so it’s a good way to confirm your suspicion. If you don’t depend much of your daily activity on third party apps, try to extend the observation as long as possible to see a difference.

Basic phone functions like SMS/MMS, voice calling, wifi, mobile data and all pre-installed apps  should still work so you can still use them while your S7 is in this mode.

Here’s how to restart to safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

Ensure that phone has enough available storage space

Some Android phones can start encountering problems when there’s not enough storage space. As a rule of thumb, always make sure that your phone has more than 10% of total storage space as free to allow apps and the operating system to operate their caches without problems. We understand the Galaxy S7 has a limited internal device storage so try to keep non-system critical data and apps stored in the SD card. Photos, videos, music, and documents are better kept in the SD card to leave the device memory with plenty of space.

Reset the device to their software defaults

One important but drastic troubleshooting that you should do is factory reset. This will return all software settings to their known working state. There may be a process or service that causes the device to reboot on its own. Doing a factory reset should effectively address that problem.

Before you perform a factory reset, make sure to back your files up.

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

Problem 2: Galaxy S7 crashed, showed black screen, won’t turn on at all

For a while, my S7 was boot looping but after a while, it would stop and let me actually use the phone. Lately however, the phone has frozen on a black screen with the blue notification light. After multiple battery drains and me trying to reset it, while failing due to freezes or crashes, my phone is completely dead. The phone looks like it’s turned off with just a black screen, and I’ve tried plugging it into a charger, so that it could charge. Before i would see the charging bar, even though it wouldn’t increase. Now all it shows nothing, and after an hour of being plugged into the wall, it’s cool to the touch. I’ve never missed with the firmware of the phone, other than updates. Any ideas on what to do? Thanks. — Harish

Solution: Hi Harish. We covered a similar issue for an S8 user a few days ago so kindly check this link. The device mentioned in that article is an S8 but the troubleshooting steps can all be applied to your S7 as well. Just remember, software troubleshooting can only address issues caused by a software glitch. If, for example, the main reason why the phone has died is a faulty battery, or motherboard error, there’s no amount of software tweaks that you can do to fix it.

Problem 3: Galaxy S7 keeps freezing and crashing after an update

I just purchased the phone yesterday and not long after getting home, it began freezing and randomly rebooting. The system had just updated, so I assumed it was just struggling a bit (like my S3 and S6 used to). It usually worked itself out on previous devices after a reboot or two. It hasn’t stopped though, I have no idea how to pin point what “seems” to trigger the freeze, I haven’t been able to do much with it since. I attempted a few different tests to troubleshoot from info here on your site, but have had no luck. Factory reset has been achieved, phone still shuts off in safe mode, and Sprint yet to be of any assistance… so i thought i would try my luck else where. No data has been transferred, and no damage to the device. — Miki

Solution: Hi Miki. There’s no common reason why a new phone would fail to turn on or keeps on restarting after an update. There must be an unknown cause why it does not work as expected after an update. Keep in mind that we’re assuming you have a brand new phone here and you were just doing an official over-the-air update. (If you tried to manually install an update via flashing, that’s a totally different issue and you should consider reflashing the previous working version). Since factory reset did not do any difference at all, you should consider returning the device to retailer so it can be replaced.

If you feel confident you can manage to try a software troubleshooting before returning the merchandise, you can attempt to reflash the bootloader. Below are the general steps on how to do that. Exact steps may be a bit different in some respects for your particular phone model so be sure to consult other guides.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Galaxy S7 edge stuck in bootloop after upgrading to Android Nougat, other issues

Hello and welcome to another #GalaxyS7 article that answers some power- or boot-related issues. We also discuss briefly what Samsung warranty covers so we hope you’ll find this another good reference for some Android issues.

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.

Below are specific topics we’re bringing for you today:

Problem 1: Accidentally dropped Galaxy S7 black screen issue, won’t boot up normally

My Galaxy S7 fell and after a while it started acting weird. I tried to reboot and now it reboots alone after maybe a minute but it seems like he doesn’t really reboot. If I open an app and it reboots after he turns up the app is still open in the latest apps. Moreover, keyboard doesn’t work, pressing long on home key to get to Google doesn’t work, and sometimes even the background picture is all black. After one time I open the phone with a pattern the handprint is supposed to work but it doesn’t.. please help. — Adi

Solution: Hi Adi. Your phone was dropped. That’s an obvious reason why your phone is now having all these problems. The drop must be bad that it damaged the motherboard or multiple components at once. We don’t know what exactly do you expect but unfortunately, we have to tell you that there’s nothing much that we can do to fix these problems. The phone is clearly suffering from hardware malfunction so stop looking for software solutions and start finding a way to have it repaired or replaced. There’s no amount of reboots and software modifications that you can do to, say, fix a shattered screen, or motherboard. Unless you have the expertise to diagnose Galaxy S7 hardware issues, repair at your level is definitely out of the question. That more than one unrelated function are currently not working is a clear indication of a possible motherboard malfunction.

If you can access Samsung service center, bring the phone there so a trained technician can assess the hardware and advise you whether it can be repaired, or if the unit needs a replacement. Since dropping your device constitutes user misuse, Samsung will definitely declare the warranty void, even if the phone is currently under warranty at this time. Be sure to prepare a repair fee before sending the phone in.

Of course you can bring the device to an independent service center but we strongly recommend that you try Samsung first since you’ll most likely pay more or less amount to have the phone fixed.

Problem 2: Galaxy S7 edge stuck in bootloop after upgrading to Android Nougat

I have updated my Galaxy S7 edge with the recent Android update, the Nougat 7, after several days, my phone keeps restarting and worst, it wont turn on until the battery is drained. So I downloaded the firmware and flash it with Odin 3, still with Nougat 7 firmware with the correct model.

I think i have done with correct procedures but now, my phone still restarts.. 🙁 so what wouldd be the most right thing to do now before going to a technician? Should i flash it with the old firmware again? Thanks in advance. — Kristinetaberna

Solution: Hi Kristinetaberna. Try to reflash the bootloader using the original firmware file for this model and see if that will fix it. Flashing a bootloader follows a slightly similar process as flashing the firmware. Below are the sample steps (exact steps may be different for your particular phone model):

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the Device Added status and its ID:COM box has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

If flashing the bootloader won’t work, consider flashing the original firmware again. If that also fails, you’re doomed; have the phone replaced.

Problem 3: Three Galaxy S7 devices keep freezing, restarting on their own, replacement Galaxy S7 showing the same problem as the first

My device slows down and freezes to the point where it is unusable and I have to force restart it at least three times a day. I’ve brought my phone into verizon and I’ve even had it replaced (twice) and it still continues to be an issue. Have done the factory reset, cleared cache etc. I have no idea what else to do and any advice would be appreciated. James

Solution: Hi James. If you’re already using your third Galaxy S7 and the issue still remains, that’s a telltale sign that it’s not a device problem. Most probably, it’s how you take care of your device or the quality of apps you install. To see if either of them is the case, do another round of factory reset and let the phone run for a few days without any apps installed or files added (if you’re using an SD card, remove it). With the phone now running a fresh, known working software version, you should be able to know if our suspicion is right. Common sense should tell you that if the phone (after a factory reset and without apps) work normally, but becomes problematic again after you’ve reinstalled apps, you’re actually causing the issue yourself (by not screening your apps more strictly).

Yes, apps can cause problems (If you only know that now, then start thanking us for letting you know). Seriously, you should know that not every app that you can find in Play Store or in other sources are built perfectly. The truth is way different! The problem you’re having now must only be happening because one of the apps you install is problematic. In other words, you only have yourself to blame for it.

To fix the problem, you must invest a great amount of time and effort in identifying the cause. Since we have no idea which of your apps is buggy, you must install each individually, making sure to observe how the phone works after each installation. This can be a tedious process but it’s the only effective method of narrowing down the possible bad app/s.

Keep in mind that it’s possible a virus or malware is responsible for the problem as well. If you don’t have an antivirus app, make sure to install one first before attempting to re-install the rest of your apps. This will help, in some degree, in detecting potential bad apps. Not all antivirus apps can detect viruses though and some apps can disguise themselves as legitimate ones during the installation, but then transforms into malicious forms after some time. This is the main reason why antivirus apps can sometimes be a waste of storage space. Your first line of defense is therefore how you screen your apps. If you tend to install apps left and right, without checking the reputation of their sources or developers, it’s only a matter of time before you’ll compromise your system, or encounter problems like what’s happening now. When it comes to today’s computing, and yes that includes using your smartphone, which is a miniature computer, it’s good to have a suspicious mindset. Just because an app looks legit does not not really mean it is. Do some research and see how other users see the app by checking their reviews. Avoid installing apps outside of the Play Store. Try to stick to official apps as much as possible.

Finally, try to limit the number of apps you install. You don’t need to make your phone an app depository. Like in real life, keep it simple and save yourself some unnecessary trouble. The less apps you have, the less chances you have in encountering problems.

Problem 4: Galaxy S7 warranty issue, S7 Samsung Protection Plus

I read here that warranty won’t cover this issue. My phone is not even a year old, never been dropped, always in cover, so I don’t really get why it doesn’t get covered. Same issue happened 2 days ago and i followed these steps and phone started to work. it worked fine for 2 days and i pluged it in to charge. picked up the phone placed it in my pocket. when i got into the car to play some tunes phone was off. Battery was at 78 when this happened. HELP. — Olle

Solution: Hi Olle. We don’t work for Samsung so we can’t declare what a warranty for a specific device in a specific country covers. However, based on publicly available sources and with our historical interactions with them, there are some things that don’t change. Below is list of things that can void the standard manufacturer warranty for Samsung devices:

  • water damage
  • damage from handling like accidental drops
  • hardware tampering (like allowing non-Samsung certified technician to take the phone apart)
  • software tampering like rooting and flashing

In some cases, Samsung can waive some of the items above if you’re willing to way for an enhanced insurance like Samsung Protection Plus. Be sure to refer to the documentation that came with the device so you’ll know what kind of warranty you have in your phone. Alternatively, you can contact Samsung directly to see if you’ve forgotten the type of warranty you have in your device.
