Galaxy s7 overheating

Why is my Samsung Galaxy S7 getting hot [Troubleshooting Guide & Potential Solutions]

  • Read and understand why a premium smartphone like the #Samsung Galaxy S7 (#GalaxyS7) heats up to the point of overheating while being charged.
  • Learn how to troubleshoot or what you have to do whenever this issue occurs to your.

You may have already seen the news about Galaxy Note 7 units that exploded, got fried or caused fire. Those cases occurred during and after charging that’s why we can’t blame other smartphone owners to be worried when their devices heat up while charging. Recently, we did receive a lot of requests for support from Samsung Galaxy S7 owners who are complaining about their devices that are heating up when plugged in.

So, in this post, I will tackle this very issue for the sake of our readers who are worrying about serious charging-related issues. Remember that while smartphones are very small and seem harmless, there were already a lot of cases wherein owners got hurt because of them. And oh, have you already seen a Jeep burned down due to a smartphone? Yeah, those things happen too. My point is, it’s imperative you take this case seriously since your safety and that of your family is at stake here.

Read on to understand why your Galaxy S7 is heating up while being charged and know what to do in case it happens to you. If you have other issues with your device, however, make sure you drop by our troubleshooting page for we have already addressed hundreds of problems sent by our readers. Odds are that we have already answered your problem before so take time finding issues that are similar with yours on our website. If you can’t find any or if our solutions don’t work and you need further assistance, feel free to contact us by filling up our Android issues questionnaire.

What to do when your Galaxy S7 gets unusually hot when charging

A smartphone that gets so hot while charging shouldn’t be taken lightly because it might be a sign of a serious hardware issue. It is imperative that you, as the owner, will take time troubleshooting your phone and here’s what I suggest you do:

Step 1: Verify it’s not caused by physical damage

This is the first thing you should do since you immediately tell if your phone suffered physical trauma due to drops or anything that could give a devastating impact on your device. An impact that may leave your phone to not work properly should leave a mark so try to check if there are scratches, breaks or anything that indicates it has come in contact with something hard.

Step 2: Check your phone for possible liquid damage

Short circuits often lead to overheating and other serious hardware issues that’s why it is imperative you verify your device isn’t suffering from any of that due to liquid damage. While the Galaxy S7 is water-resistant, it doesn’t guarantee that water cannot find its way into it. In fact, we already receive a lot of complaints from our readers about their S7 devices that stopped working after being used under water.

Remove the SD card and SIM card tray and look into the port to see if the little white sticker (Liquid Damage Indicator) turned red, pink or purple because if it did, then it’s water damage that caused the problem.

Step 3: Try to charge your phone while it’s in Safe Mode

Some apps you downloaded may have been running in the background, which also helps out in draining the battery quicker. The faster the battery drains, the hotter the phone becomes if used continuously and when you plug it in to charge, the device will heat up all the more.

Charging your phone up in safe mode won’t fix the problem but will isolate the issue immediately. If it doesn’t heat up when charging in safe mode, then third-party apps have something to do with the problem. You need to find the apps and uninstall them one by one until you can find the culprit, otherwise, you have to continue troubleshooting. Here’s how you boot your phone in safe mode:

  1. Press and hold the Power button.
  2. When Samsung Galaxy Logo appears on the screen, release the Power button and immediately hold the Volume Down key.
  3. Continue to hold the Volume Down key until the device finishes its rebooting.
  4. Now, if “Safe Mode” appears on the bottom left corner of the screen then, you can release the Volume Down key.

Should your Galaxy S7 still heat up while charging even in safe mode, then try to do the next step to see if it makes a difference.

Step 4: Connect your phone to a computer to see if it also heats up

Most of desktop and laptop computers give out half an Ampere of electric current even if they too produce 5 Volts of electricity. Your Galaxy S7’s original charger gives out 2 Amperes and works between 5 and 9 Volts, which depends of you’re using the fast charging feature. Between the computer and the charger, the latter may cause the phone to heat up more than the former. So, if your phone is still heating up when connected to a computer or a laptop, then we can almost be certain that there’s really something wrong with your device. In which case, proceed with the next step.

Step 5: Delete the system cache and try charging your phone again

The system cache can easily get corrupted. When it happens and if the system continues to use it, performance issues may occur or even problems related to charging such as the one we’re tackling here. Caches can be deleted at will without adverse effects as the system will actually create new ones that are perfectly compatible with the new firmware version. In other words, deleting system caches from time to time may even help improve your phone’s performance. But let’s set that aside for now because what is really important at this point in time is for us to know whether your Galaxy S7 would still heat up while charging after we cleared the cache partition and this is how you do it:

  1. Turn off the phone.
  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 cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

After following the steps above and the device is still heating up while charging, then you have no other option but to reset your phone to ultimately try to rule out the possibility that the problem is caused by a firmware issue.

Step 6: Do the Master Reset your Galaxy S7 before sending it to the shop for checkup

If apps that are running in the background can cause the phone to heat up when charging, firmware issues can do more and to rule this possibility out, you need to reset your device by booting up it up into the Recovery Mode again and choose the right option. After the reset, don’t install anything yet, instead try to charge the phone to know if it still heats up and if so, then you have no other option but to send it or bring it to the shop and have it fixed:

  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. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  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. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  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.

If all of these steps failed to fix the problem, you need help from a technician.

Galaxy S7 edge Google Play Store app won’t download or install app updates, other issues

Welcome to our #GalaxyS7 post for the day. We bring you apps-related issues in this one so hopefully 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.

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

Problem 1: Galaxy S7 edge gets hot when charging or using apps

For about a week now, S7 edge has been getting hot. I open and go into emails or play games or facebook etc. or using when charging, it gets hot. Had the phone approximately 1 year. I tried turning off fast charging but still does. Tried soft reboot and no difference. If I lay it down, it cools off. Would having too much saved on my phone cause it? Thanks for your help. DO NOT KNOW ANDROID VERSION ETC. Sorry. —  Bonnie Frank Tigger1566

Solution: Hi Bonnie. If overheating symptom is accompanied by another issue like phone rebooting randomly or slow performance issue, the most likely reason is hardware malfunction. As we have no prior knowledge about your phone, we can’t be more specific what exactly is happening with it at this time. An issue like this can be due to a third party app, an operating system glitch, or bad hardware so below are the things that you can try to narrow down possible causes.

Wipe the cache partition. Your device relies on a good set of system cache to load apps quickly. Sometimes, updates or app installations can corrupt the system cache, which in turn, can lead to all sorts of problems. Make sure that your device is using a good system cache by doing the steps below:

  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 cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ 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.

Install app and Android updates. If you did not set Google Play Store app to automatically download and install app updates, make sure that you regularly check that all your apps are up-to-date. The same is true when it comes to Android operating system. Any outdated app can potentially lead to incompatibility problems so installing updates is part of a user’s responsibility.

Observe the phone in safe mode. Restarting your S7 to safe mode is a relevant troubleshooting step for this case because there’s a chance that a third party app may be behind the problem. If you are fond of installing apps without checking whether they come from a reputable developer, it’s only a matter of time before you’ll encounter major problems. To see if this is actually happening in the system, you can observe how the phone works when it’s on safe mode. Here’s how:

  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.

Now that the phone has been set to safe mode, no third party apps or service will be able to run. Let your phone run for at least 24 hours and see if it continues to overheat. If the problem won’t occur, that means one of the apps is buggy, or causing the device to get warm. To identify which one is problematic, you must uninstall apps one by one so you can observe the phone in between uninstallation.

Wipe the phone by doing factory reset. If any of the steps above fail to fix the overheating problem, you must do a more drastic possible solution called factory reset. As its name suggests, this procedure returns all software settings to their known working defaults. With factory reset, you’re basically wiping the phone clean, removing any changes to the original software state. Since this pristine clean software state has been validated to work properly, it’s a good way to know if the current problem is being caused by something a user has added or changed later on. And of course, since in its default state, the software is bug free and cannot cause overheating issue, factory reset is a good way to know if the main reason for the problem is software related or not. Like in safe mode, be sure to observe the phone for at least 24 hours so you’ll notice a difference. If overheating won’t occur, that means that a software bug or app may be the cause. On the other hand, if the problem continues to occur even after a factory reset and without any apps installed, you can bet you have a hardware malfunction at hand.

Below are the steps on how to factory reset your S7:

  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.

Send the phone in. Remember, there’s only so much that you can do when it comes to Android troubleshooting. If your problem remains after doing all the steps above, contact Samsung so you can send the phone to their service center.

Problem 2: Galaxy S7 edge Google Play Store app won’t download or install app updates

Hello Droid guy. I’m having some issues with my Samsung Galaxy S7 Edge, one them being that the Google Play store not downloading, or updating applications. I’ve already tried rebooting and troubleshooting the Play Store and nothing. So I don’t know if it’s something to do with either my Internet connection or with the Play Store. Your help will be greatly appreciated. — Martin Pineda

Solution: Hi Martin. We assume that your S7 was never rooted or running unofficial software. If it’s rooted or uses non-Samsung software, there may be some restrictions specific to the rooting software or ROM that prevents the Play Store from working normally. In that case, you should seek the answer yourself as there’s nothing that we can do to help.

If your phone is running official Samsung firmware at this time, the first thing that you should do is to wipe the data of the Play Store app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the application and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application. Tap Clear Data button.

If restoring Play Store app to its default state won’t work, be sure to also clear the data of Google Services Framework app.

If nothing works still after that, do a factory reset.

Problem 3: Galaxy S7 unlocks screen when receiving SMS

When I receive a text message, it unlocks the phone in my pocket and various activities happen due to the phone being active. (i.e. random outgoing texts and phone calls). How do I stop it from unlocking and activating the phone upon receipt of a text. — Leo Grant

Solution: Hi Leo. We’ve observed this bug in older Android Marshmallow version but we can confirm that it’s been fixed with the new Android Nougat. If you haven’t updated to Nougat at this time, be sure to check if there’s a pending operating system update by going under Settings>Software update.

If there’s no available update that can be provided by your carrier at this time, we suggest that you install Samsung Smart Switch app in your computer and use it to check if you can update your phone.

To install Smart Switch on your computer, follow these steps:

  1. Open the internet browser on your computer and visit the installation page for Smart Switch app.
  2. Click on the appropriate download link.
    1. For PC
    2. For Mac
  3. Click to launch the downloaded .exe file (.dmg on Mac).
  4. Confirm that you accept the terms of the license agreement by clicking the two check boxes.
  5. Click Next.
  6. Complete the installation process by clicking the Finish button. After that, the newly installed Smart Switch app will run automatically.

Problem 4: Galaxy S7 office invites not added automatically to Samsung email app

Hi. Need Little Help, Got Samsung Galaxy S7 last week, now the issue is, when ever I get any meeting invites, I have to add it manually in Calendar. In my old Blackberry, it used to add up automatically. We are using company email & it’s not Google apps, so it’s configured in Samsung App called Emails. Is there any way, we can add the invites automatically. Thanks. — Santosh Chaudhary

Solution: Hi Santosh. Samsung’s Email app does not have an option to automatically associate an invitation from another system or app to the Calendar app. You can, instead, use Google apps and services to streamline stuff. For example, if you are using Google products like Gmail in your office, you can to use Google Calendar app in your S7 so whatever you add in your Google account while in the office, you can readily access them relatively easily in your mobile as well.

If your company email does not support Google products though, the same problem may occur so there’s really nothing much that you can do about it at the moment.

Galaxy S7 edge won’t charge, showing moisture detected error, other power issues

Hello Android fans! We bring you another #GalaxyS7 list of problems that were reported by some members of our community. We cover some power-related problems in this article so we hope that our suggested solutions will help you as well.

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 won’t charge, showing moisture detected error

Dropped my Samsung Galaxy S7 edge in the sea. The phone did not shut down. Took pictures after it dropped in the water too. working fine but just not getting charged. it says device moist. did keep the phone in the bowl of rice last night, tried charging today morning. still the same message i.e., device moist. – Deepriya Kaflay

Solution: Hi Deepriya. If your S7 won’t charge and keeps showing “moisture detected” error, it means that the system is detecting that there are still traces of water or moisture in the charging port. In order to prevent damaging the device, your S7 won’t charge unless the moisture is gone completely. If gently shaking the device won’t get rid of whatever moisture is left in the port, put it inside a bag of rice again, seal the bag, and place it near a heat producing device like the back of a TV or computer. The aim is to apply very low indirect heat around the bag to allow moisture to evaporate or be absorbed by rice. Do not apply direct heat to the phone or to the bag; direct heat will damage the device. Leave the device in that slightly heated bad for 24 to 48 hours.

Alternatively, if money is not an issue, you can bring it to a service center that fix electronics so they can dry the device using a professional tool. This process will take somewhere around 20-30 minutes.

Problem 2: Galaxy S7 not responding, won’t power on

My galaxy S7 is completely dead. When i put it on charge, there’s a battery icon with a lightning bolt that shows up. this icon will not go away unless i unplug the phone. There is no red LED indicator of it charging nor the green ‘dot’ at the bottom of the screen. also no battery percentage.

I have tried 7 different chargers with 3 different plugs, all of which are fully functional with other devices. Only 1 wire and 1 plug are strangely remotely working with the phone. I borrowed the official Samsung charger for a few hours off my friend and i am still getting the same result. i do not want to sell/send the phone to be repaired as they reset the phone. i do not want to lose the very personal information on this device. Also i do not know the ‘android version.’ — Cairns2009

Solution: Hi Cairns2009. Sending your phone in, just like when bringing your only car to a shop, can be an inconvenience. However, there’s really not much that you can do in both cases. If your S7 no longer charges or powers on, that can mean there’s an on-going hardware failure. The causes can range from faulty charging port, bad battery, or a more serious unknown motherboard failure. Identifying the real issue requires that a technician check the phone physically. Unfortunately, you’re also right, repair will most likely result to losing your personal files and customizations. If you want to get to the bottom of the issue though, you should have it repaired.

Problem 3: Galaxy S7 overheating and not responding, won’t turn on or off

Yes i got an issue with my phone like i forgot my password and i couldn’t factory reset and stuff so i gave it to a new by shop and later they did it. It was fine just that i couldn’t upgrade my phone at all. So today after a week suddenly now my phone is over heated badly and now it’s just not switching off or on. — Siddyjojo

Solution: Hi Siddyjojo. So what exactly did the shop did to allow you to use the phone again? If you don’t know, we suggest that you ask them as that might shed light why your phone is behaving the way it is right now.

In the meantime, you can either try to wait until the phone drains the battery completely, or force to restart it by doing a soft reset. To do that, just press and hold the Power and Volume Down buttons for at least 12 seconds. That should restart the device. If that won’t happen, just wait for it to use up all power. Once that happens, charge the phone again and reboot it to Recovery Mode. This will allow you wipe the cache partition and do a factory reset. If the cause of the problem is software-related, factory reset might help. Otherwise, just bring the phone back to the shop that fixed it initially and let them figure out the cause.

For reference, here are the steps on how to boot your S7 to Recovery Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP 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 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. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 4: Galaxy S7 freezing, won’t respond

Ok, so after completing the security/system update my Samsung account was having sync issues. Since i forgot my Samsung account password, i clicked i forgot my password. It brings up the account.Samsung.com starts loading the page. it’s frozen. WILL Not respond at all. — Kcole7812

Solution: Hi Kcole7812. If the phone is not responding at all, make sure that you try a soft reset first by pressing and holding the Power and Volume buttons for 12 seconds. If you can’t restart the phone this way, you can then try to wipe it’s cache partition to refresh the system cache. Here’s how:

  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 cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ 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.

A cache partition wipe is usually followed by a factory reset if the issue persists so don’t hesitate to do that. To factory reset your S7, follow these steps:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Problem 5: Galaxy S7 stops working after failed flashing procedure

I updated my phone by the help of software name (ODIN) . In this software, I got options “Auto restart,” “Remove partitions,” “Clean everything /format.” I checked all the option and I connected my phone with PC by USB cable. I put my phone on update mode by pushing volume down key +home key + and power key. After 20 minutes on the pic screen uptake successful, then my S7edge smartphone get offed and never get on again, even if I put in the charge. doesn’t show any light … Seems completely dead, I tried safe mood, everything possible by pushing keys for different purposes. — Iqbal

Solution: Hi Iqbal. This is exactly one of the main reasons why Samsung does not recommend users tamper with the software. There are a lot of things that can go wrong when modifying the official software and unfortunately, there’s no easy to know where the problem lies. Sometimes, the steps in flashing or updating via Odin can vary depending on your phone model. One wrong step and you’ll end up with a bricked device. We suggest that you contact the source of the flashing guide you’re following right now and let them trace which step caused the problem. We can’t do it for you since we don’t have the complete details.

Galaxy S7 reboots on its own when in an area without cell coverage, other issues

Hello Android community. Welcome to the new #GalaxyS7 article that addresses some common issues for this device.

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 overheating when charging, won’t fast charge

My Samsung Galaxy S7 has not been operating correctly for a couple of months. It is getting hot both when charging and when unhooked and in my bag (the worst). I am also finding it not charging except with a fast charger and will not fully charge starting a couple of days ago. It is connected right now and shows the lightning bolt but is losing charge.

One other issue is that the screen saver comes on and interrupts me as I am trying to log into the phone. This started prior to this problem although I have noticed heat on and off since I had the phone. I have already done the delete of the system cache as you suggested. I am leaving for Mexico in a couple of days and it is critical that my phone works. Thanks! — Misha

Solution: Hi Misha. We are here to provide software solutions to Android problems. We assume that your phone has not been dropped or got wet before as they are usually the two most common reasons for hardware malfunction. The software solutions that you’ll usually find in the internet won’t fix any hardware defect. If the problems you mention above occurred after the phone got water damaged or accidentally dropped, don’t waste your time browsing our blog. Instead, simply bring the phone to Samsung or to an independent service center so the hardware can be checked.

Now, if your phone was never dropped or exposed to elements before, it’s possible that the cause may be software in nature. This means that you might be able to fix the problems without resorting to repair.

Try a different working charger

Since you appear to have a charging problem, the first thing that you want to do is to see if it’s due to a bad charger. If you have a friend with a Galaxy S7, try borrowing his/her fast charger and see if it works in your phone. If the phone still fails to fast charge, there may be a problem with the charging port. In that case, you’ll want to send the phone in so the defective port can be replaced.

Sometimes, a malfunctioning charging port can also cause the bottom part of the phone to get uncomfortably warm when charging. If this is happening in your device, that’s a clear indication of a bad charging port issue.

As a workaround, try using a wireless fast charger that came with the device. This will allow you to charge the phone. The USB port will still remain defective though and you won’t be able to move files via USB cable as long as the said port is not fixed.

Install app and Android updates

Sometimes, updates can fix problems and address glitches. Make sure that you install the latest versions of all your apps and the operating system.

Observe in safe mode

Another good troubleshooting step that you must do when it comes to any Android issue is to see if a third party app is problematic. Since apps are the lifeblood of smartphones, it’s just logical to check if any one of them is messing up with the system, leading to the particular symptoms you’re experiencing. When booted to safe mode, all third party apps will be suspended, allowing only pre-installed apps to run. If the phone works normally and the symptoms are absent at this time, that’s an indication that all of them are being by most probably an app.

To restart your S7 to safe mode, kindly do these steps:

  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.

Wipe the phone with factory reset

A drastic software solution that you do as a final step is factory reset. This procedure will restore all software settings to their defaults so if a glitch that has developed over time is the one causing all these problems, you’ll most likely get rid of it. Factory reset will erase your phone’s user data such as photos, videos, etc. so be sure to create a backup before doing it.

Below are the steps on how to factory reset your S7:

  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 reboots on its own when in an area without cell coverage

Problem with Samsung Galaxy S7 active. i was working in an area with no cell coverage (signal). I install hughesnet and use an app to complete each job. i would say 85% of the places I go don’t have cell coverage. this has happened multiple times this summer. i just assumed the phone got too hot because it was 100°+. However this time it was around 55°. Phone starts power cycling and wouldn’t let me do anything. it wouldn’t even show keyboard when I tried to use between power cycles. then as soon as I get back in to an area with cell coverage the phone starts working. no problem since. until the next time it happens. whenever that will be. — Kevin

Solution: Hi Kevin. If you suspect that HughesNet Mobile app is associated with the problem you’re having, it’s pretty simple to nail down. Simply uninstall the app and all its associated services and see how your phone works in an area without cell coverage. If it doesn’t reboot on its own, then you bet it’s the HughesNet Mobile app that’s problematic. Alternatively, you can do a complete wipe by doing a factory reset so you can observe how your phone works in an area with no cell signal. If the phone works when there are no third party apps installed including HughesNet Mobile app, you’ll know the problem is being caused by an app, most probably by HughesNet Mobile. To fix the issue, be sure to let the developer of the said know so they can take a look at your particular system and situation.

Problem 3: Galaxy S7 won’t enter Recovery Mode after failed flashing procedure

I was having trouble with 6.0.1 so i flashed Nougat and decided to flash back to 6.0.1. i  always do a master reset before flashing on my phone. Well, while flashing, i noticed that it failed and i noticed on Odin that it failed because it could said that complete operation failed because it could not write. I therefore turned my phone off and tried to restart it but the phone stayed black and i tried to enter into recovery mode, the blue came on saying that i was entering into recovery mode and went black again. — Lamar I

Solution: Hi Lamar. There a lot of variables that can come into play when flashing and some of them can lead to serious problems. Since there’s no way to know what causes the problem you’re having right now, we suggest that you do these things:

  • ensure that you’re using a correct flashing guide for your particular phone model
  • reflash the bootloader

Reflashing the bootloader is similar to flashing the firmware. Below are the generic steps on how to do it. The exact steps may be a bit different for your phone model so be sure to cross check our guide with 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.

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 restarts on its own, won’t stay on

Hello there. I hope you’ll return to me as fast as you can, Let me clarify the problem.

I use Galaxy S7 Edge. I was on a flight so my phone was turned off for quite some time and when I turned it on, it starts to heat up and restart over and over again, like every minute or less or whenever I tried to use it. I wasn’t that alarmed at first as I have experienced the same situation a couple of times before, So when I get to my hotel, I switched it off and  put it on charger. But when I tried to turn it on after fully charging it, instead of going back to normal like before, it stays the same, if not worse.

I am currently admitted in a hospital, alone, in a foreign country I’ve never been in before. I am so frustrated that I can’t even speak to my family or friends as my connections were all via Whatsapp, Viber , Imo etc…which were in my phone. I am currently using my laptop with a life span of 10-20 minutes or less. I can’t even charge my laptop since I didn’t bring an adapter that fits the sockets here. Please please please I’d really appreciate it if you could help me as soon as possible. Thank you.

P.S. I did try to put in in safe mode as you described but it didn’t work. Now it’s restarting like every 10 seconds or so. — Beza

Solution: Hi Beza. Firstly, we don’t intend to make our answers be used for emergencies so hopefully this post reaches you in time. Thedroidguy receives hundreds of requests for assistance everyday so we may not be able to publish posts that includes time-sensitive cases like yours.

Secondly, a problem like yours needs time in order to isolate the root cause. A randomly restarting phone can be the result of a number of possible reasons, each of which needs to be checked. Telling us the symptom only helps us to identify the real problem so much. We need more than the symptom to pinpoint where the problem lies. We understand that our method of correspondence is a one-way street so we don’t have the luxury of asking you back other pertinent questions and the full history of the device.

Since you mentioned that your phone had been acting up previously, though it managed to boot back up normally, there’s a big chance you may have a bad hardware. We’re thinking of a possible malfunctioning battery here, which, unfortunately, may require you to send the phone to a shop for repair. Normally, if the problem is caused by a failing battery, the phone won’t be able to stay powered on for a few minutes. To see if that’s the case, we suggest that you try to restart it to other modes — Recovery Mode or Download/Odin Mode.

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP 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 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. 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.

Any of these modes runs on a code separate from Android operating system so if the issue is on the software side (Android glitch), the phone should remain on. However, if your device continues to reboot on its own, or won’t boot successfully to any of these modes at all, that’s a clear sign that you have a possible hardware issue. As mentioned, it can be a battery issue, or any other bad component in the motherboard. A malfunctioning power management IC often shows similar symptoms so if that’s the cause, you’ll most likely end up with an expensive motherboard replacement, or an entire phone replacement.

If your phone becomes stable when booted to Recovery Mode but returns to the same problematic state after booting it again to normal mode, consider wiping the phone with factory reset. The problem is most likely caused by an unknown operating system glitch, or a poorly coded app. Wiping the phone clean and returning all software settings to their defaults should fix the problem.

Problem 2: Galaxy S7 edge battery stopped working, overheating, slow performance, won’t turn on due to bad battery

Hi. I have this Samsung Galaxy S7 edge. It seemed to work fine until a couple of weeks before when it suddenly froze and heat up like hell and restarts with all the LEDs on. After the restart it seemed to work fine until a day or less later, it does this again. Sometimes, it froze after heating up like hell so i perform soft reboot and then it seemed to work fine. Today it did that again and after soft rebooting, it heated up and turned off and since then it’s been a cold brick — doesn’t charge up, doesn’t do anything, no response upon plugging it in to a charger or pressing buttons. It’s just dead. Help. — Ahmadgujjar176

Solution: Hi Ahmadgujjar176. All the symptoms that showed prior to the phone ending up totally dead are consistent with a hardware malfunction, most probably a dead battery. One of the signs that there’s an on-going battery trouble is overheating even when the phone is in normal state. Together with the rest of the symptoms like slow performance and failure to boot up, there’s a big chance that the phone’s battery may have succumbed to a premature death. Unfortunately, this means that a professional will have to open the phone up and replace this part. Sure you can also do it yourself but keep in mind that the job requires basic electronics knowledge and some tools. If you want to replace the battery yourself, try to search Google for some guides that will allow you to do so.

Problem 3: Galaxy S7 won’t load to normal mode, stuck in Odin screen

So i have my Galaxy S7. A few months ago it was working just fine. i was able to get all my pictures and stuff off of it and what not. It sat in my nightstand for a few months after that so the battery did completely die. After i plugged it in for a while and got it to charge again, i keep getting stuck at this screen that says Galaxy S7 custom screen. it has a lock which is in the unlocked position and it is a black and white screen.

i have never rooted a phone or changed any major files so i’m not sure how it could work. And then when the battery completely dies i get this screen.

I have tried to boot into Recovery mode and clear cache and factory data reset. however the data reset don’t really finish. It’ll act like it for about 30 seconds then go right back to that Galaxy S7 custom screen. thank you for any support that you can give me on getting this issue fixed. — Kevin

Solution: Hi Kevin. Looks like your phone has a corrupted bootloader, which is a separate code that runs independently of the operating system. In fact, it runs before Android operating system loads and it’s a necessary software process to ensure that Android won’t encounter any trouble when booting up. With your situation, the bootloader may be at fault. We don’t have the history of your device so we can’t tell you why this is happening. To fix the problem though, you can try to reflash the bootloader back to stock. Below are the  general steps on how to flash a bootloader of any Samsung Galaxy phone. The exact steps may be slightly different for your 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.

Don’t forget, flashing is a risky software modification. Not doing the right steps may complicate things and at worst, cause permanent software damage. Be sure you know what you’re doing before you proceed. If you’re not confident with your Android troubleshooting skills and knowledge, let a more experienced user or professional do the job for you.

Alternatively, you can let Samsung fix the issue. Just bring the device to their store and see if someone can help you flash the software.

How to fix a Samsung Galaxy S7 that started heating up with screen turned white [Troubleshooting Guide]

Overheating can often lead to more serious problems no matter what your phone is. Some of our readers contacted us about the issue with their Samsung Galaxy S7 which, according to them, started to heat up to the point that it would be too uncomfortable to touch or hold. There were also others who said that the screen of their device turned white and seemed to have become unresponsive.

In this post, I will tackle the heating up issue on the Galaxy S7 accompanied by white screen. I will be citing one of the issues sent by our reader that best describes the problem. Then, we will take into consideration all possibilities and rule out each of them until we can easily pinpoint what the problem really is and what needs to be done to fix it. So, if you own this phone and are currently bugged by a similar problem, continue reading below as it may help you address the problem you currently have.

But before we jump right into our troubleshooting, if you have other issues with your phone, make sure to drop by our troubleshooting page for we have already addressed hundreds of problems with this device since it was released. Find issues that are similar with yours and use the solutions and/or troubleshooting guides we suggested. If they don’t work or if you need further assistance, feel free to contact us by filling up our Android issues questionnaire.

How to troubleshoot your Galaxy S7 that heats up with its screen turned white

Problem: Hi, It started when S7 Edge sudden heats up, I shut it off for 2hrs to cool it down. When I opened to check what would be the faulty, it’s apparently heats up again. All of a sudden, white screen a appears thinking yet though AOD still displays normally.

Solution: Overheating issue is one of the most common problems that users were complaining about. As a matter of fact, there are number of reasons you need to consider why the device heats up and the screen turns white without apparent reason. If your phone was dropped or has been soaked in the water that would be a clear indicator that it is a hardware problem triggered it. If this is the case, we can’t do anything about it, instead, just bring your device to the nearest shop in your area so that the technician can check it for you.

ut before doing so, we recommend you to do first the basic troubleshooting procedures for it might as well a system glitch or the firmware caused the problem. Here are the methods that you should follow:

Step 1: Perform forced reboot

Since the battery of S7 Edge can’t be removed, this method is very effective and it’s the equivalent of battery-pull procedure to those devices that has a removable battery. Through force reboot the device memory will be back to its original state and closing all apps that runs in the background. Just press and hold the Power and Volume Down keys simultaneously for 10 seconds and wait until the device reboots. However, after the procedure observe if it is still overheating, if so, proceed to the next method.

Step 2: Restart in Safe mode

The purpose of booting your phone in safe mode is to figure it out if the issue you are having is caused by one of the downloaded applications you installed in the firmware. In this method, all third-party apps won’t be loaded and only the pre-installed will run in the system. But remember that the problem won’t be resolved by this procedure, instead, it only gives you an idea if there’s a culprit triggered the issue. Here’s how:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

So, if it boots up while in this state, then find the app triggered it by uninstalling each app you have until the device function normally. But if it still persists while in this state, move to the next procedure.

Step 3: Clear the System Cache Partition

If you haven’t tried deleting the cache partition started from the very first day you bought the device, then it could be the outdated caches is the reason that this is happening now. By deleting all old temporary files in the directory we are letting the device to create newer caches that is compatible and easier for the system to read. But nothing to worry about this method, your personal settings, apps and data won’t be erased.

  1. Turn off the phone.
  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 cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Step 4: Master Reset your device

Remember, you can do the reset on your phone if all procedures you performed were unable to resolve the issue. Unlike to previous methods, this will delete all files and data on your device. But the good thing is, the firmware will be back to its default settings and all bugs, data and apps you downloaded  triggered the problem will be removed. So, before you can do the reset make sure to backup everything. This is how to reset:

  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.

In case you don’t know what your Google ID and password are, then I suggest that before you reset your phone you disable the Factory Reset Protection (FRP) first so that you won’t be locked out.

How to disable FRP on Galaxy S7

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
