Galaxy S7 wifi issues

Laptop can’t connect to the internet when using Galaxy S7 mobile hotspot, other connection issues

Hello Android community! Welcome to another #GalaxyS7 troubleshooting post for the day. We discuss some of the common wifi and connectivity experiences reported by some users so hopefully you’ll find this 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.

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: Laptop can’t connect to the internet when using Galaxy S7 mobile hotspot

My Samsung Galaxy S7 can connect to my laptop via mobile hotspot but i can’t get internet. It says connected no internet on the laptop. Have tried the basics but no easy answer. My wife’s S6 connects no worries.        — Johnpuglia

Solution: Hi Johnpuglia. The fact that your wife’s mobile (S6) can connect to your S7’s mobile hotspot and access the internet normally means that the problem is in the laptop, and not in your phone. The computer may not be configured properly that’s why even if it says it’s connected to the hotspot, which means it’s connected in a local network, it is not able to connect to the bigger outside network which is the internet. It also indicates that you should focus your troubleshooting in your laptop rather than in your Galaxy S7. Our blog supports smartphones only but you can try some of the basics in laptop wireless troubleshooting below. They are only for Windows computers. If you have a Mac, contact Apple support for more in-depth troubleshooting.

  1. Open Control Panel.
  2. Click on Network and Sharing Center.
  3. Click on Change adapter settings.
  4. Look for the Wi-Fi adapter (should usually say Wi-Fi).
  5. Right click on Wi-Fi adapter and click Properties.
  6. Click Configure.
  7. Click Advanced tab.
  8. In the Property section, scroll down and look for Wireless Mode.
  9. Click on Wireless Mode.
  10. Depending on the wireless mode capability of your laptop, there should be at least one option in the Value section. If you have a few options in Value section, make sure to try each of them to see which one will work. As a general rule, you want to select the option that’s compatible with common wireless standards such as 802.11n or 802.11g. For example, if you have an option that says 802.11a/b/g/n, then try that first.
  11. Once you’ve selected the preferred value, don’t forget to hit OK to confirm the selection.
  12. Check if your laptop can now connect to your mobile hotspot.
  13. Do steps 1 to 11 again if a certain Wireless Mode value won’t work.

Remember, the problem is not in your Galaxy S7 nor with your internet service. If the laptop continue to fail to connect, contact the laptop maker, or find a PC troubleshooting site that may help you.

Problem 2:  Galaxy S7 can’t answer “unavailable” calls

Hello! Recently, starting about this January, my phone is not letting me answer calls deemed “Unavailable.” I have checked that I am not blocking them. The phone rings, and shows options to answer, but does not let me answer and considers them “missed” calls. I need to be able to answer these. I have reviewed apps that might interfere and don’t see an issue. Is there anything else I can do? Thanks! — Kelly

Solution: Hi Kelly. Try restarting your phone to safe mode then simulate the issue again. When in safe mode, third party apps that may interfere with your calls will be disabled. If your calls will work just fine, then you’ll know one of the apps is to blame. We don’t know if you regularly receive calls but we suggest that you wait for them while the phone is in safe mode to test our theory out. This means that you’ll have to let your phone run in safe mode until the call you’re having problems with arrives. To boot to safe mode, follow 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.

If nothing changes and the issue reappears even when safe mode is enabled, do a factory reset and replicate the problem again. Be sure that you don’t install anything until you receive the same type of calls again. Doing a factory reset should be the last step that you can do in this case. If nothing works still, contact your carrier so they can provide firsthand assistance.

Problem 3: Apps in HP laptop won’t work when connected to Galaxy S7

Hi. I am currently using Samsung S7 edge. My issue is that my HP will indicate a presence of Internet connectivity but there are times where my apps still can’t work due to absence of Internet connectivity and I have to restart my phone. So I don’t know if it is a network issue or a problem with my phone. — JQ

Solution: Hi JQ. We don’t think we understand your connectivity setup here. Are you trying to connect your HP computer to your Galaxy S7 mobile hotspot? If yes, refer to our suggestion for Johnpuglia above. Make sure that the problem is not due to poor mobile data connection in your S7. If your S7 is receiving spotty mobile data connection, that can be the reason why internet connection to other connected devices is unreliable. In this case, you must work with your carrier so they can help you troubleshoot your mobile data connection first. Otherwise, the issue must be laptop specific, which means that you’ll have to troubleshoot it instead of your mobile.

Problem 4: Galaxy S7 wifi showing lock symbol after an update, not charging fully to 100%

Hello sir. I am facing some issues after updating my S7 edge G935FD dual SIM to latest July patch. After updating, my wifi works with much lag and a lock sign appears on wifi symbol and after sometime data again continues but then again this , a lock sign over wifi. When i get in settings>connection>wifi it shows internet may not available when there is lock sign on wifi symbol.

The second thing is that battery stops charging sometimes at a percentage less than 100% and it remained there for many hours. but when i eject and replug the charger it again resumes charging. Can this be because of updates? Should i reset? — Killerhassan19

Solution: Hi Killerhassan19. Updates are basically changes to existing system and sometimes, these changes may not work as designed. It does not necessarily mean that updates are there to cause problems. In the contrary, updates are most of the time released to fix known bugs. But since Android and apps are constantly evolving, there will always be many moving parts that Google or developers cannot anticipate. If you’re positive that the issues started after you installed an update, these are the things that you can try:

Wipe the cache partition

  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 updates

  1. Open Play Store app.
  2. Tap Options (three horizontal lines in the top left).
  3. Tap My apps & games.
  4. Tap UPDATE ALL.

Perform a factory reset

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  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.

Problem 5: Can’t connect Galaxy S7 to TV via HDMI

I’m trying to connect my Samsung Galaxy S7 to my TV in order to stream Hulu from my phone to my TV. I need to do it wired because I have no WiFi and my TV does not support screen mirroring. I bought a universal 11 pin MHL cord in which I hooked up all connectors correctly (HDMI to TV, usb to power source and micro usb to phone) but nothing happens aside from my phone being charged. Am I using the wrong cable? Samsung technical help said that not all TV’s are MHL compatible…is that right? Could I use a regular HDMI cord with a micro usb adapter to connect my phone??? — Cassady

Solution: Hi Cassady. Samsung has stopped wired connections to TVs starting with the Galaxy S6 so you’re out of luck. There’s just no way that you can make your phone stream contents directly to your TV via HDMI. We know this isn’t a great idea from Samsung but this is what we have right now. If you really want to stream contents from your phone to your TV, you must go wireless by using supported accessories such as HomeSync and an AllShare Cast dongle, or Chromecast.

Problem 6: Galaxy S7 wifi keeps disconnecting, won’t connect to wifi

I am from Brunei and I have had my S7 for a year now. A few months ago when i started to connect my wifi (I rarely use wifi before) and my connections started to stop working. Even Bluetooth and hotspot. I’ve tried the suggestions people posted on website like, restart, changing to airplane mode, dialing *0010# (something like that) and it’s still the same! I’m getting fed up now with my phone!

Also i have just update the software today and it’s still the same. Your country list does not have Brunei so i chose Malaysia as the closest to us. — Jaz

Solution: Hi Jaz. Try doing a factory reset and see what happens from there. If wifi will continue to drop or won’t connect at all, your phone’s networking chip that handles connectivity tasks including wifi must be malfunctioning. Contact Samsung or your carrier for support.

How to troubleshoot Samsung Galaxy S7 Wi-Fi connectivity issues & other Internet related problems

The new #Samsung Galaxy S7 (#GalaxyS7) has a Wi-Fi bug. It’s a minor one but nevertheless annoying. It affects the syncing capability of the phone especially Gmail. Samsung already acknowledged it and even started rolling out minor updates to fix it and in the U.S., #Verizon followed suit. For sure, other carriers and service providers will roll out updates sooner than later.

Galaxy-S7-Wi-Fi-problems

It is a Wi-Fi bug and if you get Internet service through mobile data, you won’t be able to experience this annoyance. If, however, you have Internet-related issues while using data, then that’s a different story but I will also address that one here.

The first part of this troubleshooting guide is to provide you with workarounds so you’ll be able to continue using your phone despite the bug that keeps bugging you. At the later part of this article, I will address some of the Internet-related concerns Galaxy S7 owners reported.

Before anything else, for our readers who may be experiencing other issues, please visit our Galaxy S7 troubleshooting page. We list down every problem we address each week so there’s a chance your concern has already been addressed by our team. Try to find issues that are similar to yours in that page and use the solutions we provided. If, however, you need further assistance, you can always reach us by completing this questionnaire. Please provide as much details as possible so we can give you accurate troubleshooting guides and/or solutions.

Workarounds for the Galaxy S7 Wi-Fi bug

These aren’t solutions but workarounds or temporary remedies so you can continue using your phone despite the symptoms the bug is showing. Again, the bug is minor but very annoying especially if you rely on Wi-Fi to connect to the Internet. So, if you noticed your phone is showing one or two of the signs below, try the workarounds I cited:

Symptoms

  • Gmail not syncing properly
  • Wi-Fi is very slow
  • Wi-Fi keeps disconnecting and reconnecting
  • Connection lost even if the phone isn’t idle
  • Wi-Fi On/Off switch grayed out

Workarounds

  1. The first thing you should do is to restart your phone. The bug is actually triggered when the phone is being used; it doesn’t initiate during boot up. So, basically, the problem will be temporarily fixed when the phone is rebooted.
  2. If you don’t wait a few seconds of booting up, there’s another thing you can do–turn Wi-Fi off and then turn it back on. The connection gets refreshed when the device reconnects and it’s actually one of the most used workarounds for this bug, however, the problem seems to manifest again a lot quicker than when you reboot your phone but anyhow, it helps.
  3. Disable Bluetooth. Some users reported that Bluetooth may be one of the triggers of this bug as the problem often occurs when it is enabled. So, try disabling it and see what happens.
  4. Disable other location services. If you often use GPS and/or other related services, this issue will be a pain because in order for the Wi-Fi to work flawlessly, location services must be disabled. Others also said uninstalling apps that use location services will also temporarily fix the problem.
  5. Check for firmware update and download it if there’s one. Again, a few service providers may have already rolled out updates that may patch this problem, so try to check for it from time to time.

 

We don’t know how widespread the problem is but if you’re one of the unlucky ones, at least, you can do something about it. I hope that this simple guide can help you until help arrives.

Internet Problems with Galaxy S7

Here are some of the Internet-related problems we received from our readers:

Q:I have 2 new Samsung S7 phones. When I turn hotspot on my laptop connects fine to mobile 1 and has access to internet. When I try to connect laptop to mobile 2 hotspot it connects but will not give me internet.   Data is turned on and I have internet access on both phones. My laptop internet trouble shooter tells me it is disabled locally.

A: All we need to do is find out whether the problem is with the phone or your laptop. So, here’s what I need you to do:

  1. Make sure the phone you’re having issues with has internet connection.
  2. Turn on its hotspot.
  3. Now, connect your other phone to it and see if it can get service.
  4. If the internet works on the other phone, it’s most likely an issue with the laptop but it’s more of a compatibility issue than anything else.

But the thing is, either your phone can get internet connection or not, you still need to bring the phone in for checkup. It’s a new phone and if I were you, I would ask for a replacement.

Q:New Samsung galaxy S7, SM-G930F, can’t log into some websites. I put in password etc. and the page resets back to the login page. I use chrome but have tried the native internet too. I’m still using my S6 as the second phone and it logs in no problem.

A: If it can log in to other websites, then there’s no problem with the phone. The issue may be in websites you’re trying to log in to but we really don’t know for sure. It could have been a lot helpful for us if you gave us a hint what websites you were trying to log into. I also think it’s not an issue with either Chrome or the stock browser. Try calling the tech support of the websites and inquire about the problem. May be they were having service maintenance during the time you tried to log in.

Q:My new Galaxy S7 can’t connect to the internet using data. I have subscribed for an unlimited data but can’t use it. I just got the phone and the tech already registered in to their network so I now have text and calls but no internet. How can I fix this?

A: I understand you already got the device provisioned and it already has all basic services except Internet. Well, you need to set your phone to connect to your provider’s network but if the rep already did that, then all you have to do is enable mobile data. Once enabled, you should be able to get internet service, otherwise, it will be the APN that has issues–either it was configured incorrectly or haven’t been configured at all. I suggest, you call your provider again and report this problem. The rep should be able to help you with it.

Q:I have an S7. Yesterday it froze and I had to press and hold the Volume Down and Power keys to reboot it. But once it was ready, I wasn’t getting internet and the Wi-Fi icon was white. When I went to Settings to turn Wi-Fi off, it was greyed out and I can’t do a thing. I already rebooted many times but the problem remained. What should I do?

A: It must be the cache that got corrupted when the system crashed. So, try wiping the cache partition via recovery mode:

  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.

Q:I downloaded a bunch of apps and then there were these pages that kept popping up about some apps that could help me clean my phone of viruses. I don’t want to install those things but they kept popping up so I decided to try one but after the installation, the phone froze and I could no longer connect to the internet. What is the problem?

A: You may have installed some malicious apps so you need to uninstall those. Since you voluntarily installed one, you should be able to remember its name. Now, if you can’t do something on your phone because ads keep popping up, then boot your device in safe mode first and uninstall the app from there:

  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.

Q:My Galaxy S7’s screen blacked out all of the sudden and it took me hours to bring it back on but this time, it started to freeze and lag a lot of times so I knew from that moment on something was wrong. I just continued to use it but it became really slow and the internet connection is really slow as well. Please suggest something I can do to fix this problem. Thanks.

A: Honestly, we don’t know what caused the screen black out. I believe it was a system crash you experienced and it must have been caused by something–it could be an app, a firmware glitch, etc. Since we don’t have a hint what’s causing all this, there’s one thing I want you to do; do the master reset. I’m not sure if you’re still within the replacement period but after the reset and the device still keeps lagging and freezing, you need to have it replaced or, at least, fixed by your provider’s technician. Here’s how you do the master reset on the Galaxy 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.

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.

  1. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. 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.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

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, or you can install our free app from Google Play Store.

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: Galaxy S7 and other Android devices load websites slower using a mobile browser

OK here’s a tough one. I’m a cable guy and also have a degree in computer science.  I was at a customer’s house and i fixed all the cable issues for their modem.  I can run a speed test directly connected with a laptop and get almost 400MB download. Wirelessly with the Speedtest app i can get about 280 or so; they’re paying for 300.  I can browse the web with a browser with lightning speeds with a windows computer, Apple phone and i even brought a computer from home that has a Linux partition on it and they all work fine.

Also, with the Android devices I’ve used it takes almost 4 minutes to load any web page. I’ve tried multiple devices (2 different Galaxy S5 phones, Galaxy Tab S2, Nexus, Galaxy S3, Galaxy S7 and my Note 5). All of these devices are having the same issue. The devices run anywhere between KitKat, Lollipop or Marshmallow. All apps work fine on the devices for speed except the browsers. The browsers I’ve tried are Chrome, Firefox, Flashfox, and the native Google browser.

I’ve tried swapping the gateway to 3 different brands and this issue continues to persist.  I’ve looked closely at the DNS settings and double checked they are correct. I’ve tried typing in the domains direct IP address and the same issue happens. Tried different browsers on several of the devices. I disabled IPv6 on 2 of the routers to check to see if there is a conflict there.

Any ideas would be great to help this family out? I’m completely out of ideas. — Duff

Solution: Hi Duff. This is interesting. No normal mobile browser should take 4 minutes to load a webpage. Even a download speed of less than 10Mbps should not take that long.

Slower page-load time in a mobile browser can be due to a number of reasons including a fault on the server-side. Not all websites are optimized to be viewed in mobiles and a lot of extra information that are not necessarily useful for mobile use may be sent in the process, resulting to longer load time. In order to save effort and money, site developers may not want to build a separate mobile website, which is not really a problem for sites with deep pockets like Google.com or Facebook.com.

If the Android devices you’ve tried still load known fast mobile sites like Google or Facebook longer than a minute, then something must be wrong with these handsets.

Try to see if there’s any common third party app on all of them as that may be causing the slow load time. Or you can try to boot one of the handsets to safe mode to see the difference. Better still,  consider doing a factory reset on one of them and try the mobile browser again without installing any app. This should give you an idea if there’s a third party app that’s causing the slowdown, or if a firmware glitch is to blame.

Problem #2: Galaxy S7 keeps restarting on its own and changing settings and notifications back to default

Gave up an HTC that was old to get an S7. Worked fine the 1st day, except it was restarting every couple hours. When it would restart it would change several settings back to default. Only problem was that it wouldn’t change the same ones every time. Second day ALL the notifications quit. Just shows Sprint in the top right corner. No active apps. No temperature from weather app that was there day before. Turn all the notifications I could find on.. Now the blue light blinks but it doesn’t tell me what i need to look at… Haven’t done a hard reset yet. I am hoping there might be an alternative. Any help will be reqarded with at least 1 or 3 Thank Yous. — Thomas

Solution: Hi Thomas. Did you install anything like an app or update prior to noticing the problem? If you did, make sure that you clear the phone’s system cache first. Outdate or corrupted system cache can lead to all sorts of problems so it’s best to ensure that it’s refreshed.

  • Turn off the phone.
  • Once the phone has completely shut down, press and hold Volume, Home, and Power buttons at the same time.
  • Wait until the Samsung logo appears before releasing the Power button.
  • Once the Android logo shows up, release the two other buttons.
  • Wait for the Recovery menu to appear (may take up to a minute).
  • Go to wipe cache partition option using the Volume buttons, then press Power button to confirm.
  • Wait for the device to wipe the cache partition
  • Once the cache has been deleted, Reboot system now option will then be highlighted.
  • Press Power button again to confirm the reboot.

If nothing will change after wiping the cache partition, your next task is to see if an installed third party app is to blame. You can do so by booting your S7 in safe mode. Here’s how:

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

While Safe Mode is enabled, no third party app or service is permitted to run. If the issue won’t occur, that’s your clue that one of your apps is the culprit. You have to uninstall apps until you have eliminated the source of trouble.

Problem #3: Galaxy S7 Edge charging session takes longer than expected

Hello. My Samsung Galaxy S7 Edge is charging but was taking so long. It took 5 hours to charge it but it’s only been 77%. When I bought the phone, they said I should drain it when first before charging it. Charging should take 3-4 hours. But yesterday, I did drain it but had to open it because I had to do something. While I was editing my files in Microsoft, it took me 6 hours. And it was still 22 % while charging. So I shut the phone down. After 2 hours I pulled the plug. It’s only 22 percent. Then it got down to 11 percent immediately. I drained it by using it. After hours I charged it again. So yeah after 6 hours it’s only been 77 percent. What should I do? Thank you.. God bless you…– Jacky

Solution: Hi Jacky. First of all, the new Galaxy S7 has a fast charging feature that should shorten the charging time. We assume that you’re using the original Samsung charger that came with the phone and that Adaptive fast charging feature is enabled on the device. Samsung claims this feature can charge your device up to 50% in only about 30 minutes. To activate this feature, just go to Apps>Settings>Battery, and then tap the Fast cable charging switch.

Now, in order for fast charging feature to work as expected certain conditions must met that includes the following:

  • The phone or screen must be turned off
  • The Samsung Adapative charger or one that supports Qualcomm Quick Charge 2.0 must be used. If you are using the original charger then that’s the one.
  • The device must not be overheating. Keep in mind that it’s perfectly normal for the phone to get a little warm during charging. However, if it becomes uncomfortably hot, it can automatically shut the fast charging feature down, or the entire charging session entirely. This is a normal operating procedure of the device to prevent damaging itself.
  • Make sure that you are charging inside a room with normal room temperature. If the ambient air temperature goes up, the fast charging feature will turn off automatically.

Sometimes, multiple apps and services running actively and in the background during a charging session can drain power faster than the charger can deposit a charge to the battery. Consider booting the phone in safe mode or simply turn off the phone to achieve faster charging time.

The following best charging practices may also help you:

  • Turn off your device while it is charging.
  • Verify that you are using the Samsung USB/charging cable and Adaptive Fast Charger included with your device, not third-party accessories.
  • Ensure the USB/charging cable is connected securely and is not being blocked by a cover or case.
  • Check whether a battery or charging indicator appears on the device’s display when the USB/charging cable is plugged in.
  • Charge using a wall outlet, not a computer.
  • When the battery is fully charged, disconnect the device from the USB/charging cable.

Problem #4: Galaxy S7 not detecting SIM card error during calls

I really have several issues but my biggest issue is that I frequently get an error message that tells me to reboot my phone because the SIM card is not detected. Lately this happens right in the middle of phone calls.

Also, when I make phone calls my connection speed drops from 4G LTE down to 4G. These might be inter-related maybe not.

Another issue: sometimes when I call someone I do not get a ring tone then I cannot hear the person i called. Usually I have to reboot my phone before I can make a call that will actually allow me to hear the other end of the line. It says dialing but I never hear the dial tone then I can’t hear the other end.

When i record video the playback is horribly distorted. Like not even recognizable. Thanks for your help in advance. — John

Solution: Hi John. All the concerns except the first one about the SIM card not detected error may be firmware-related so it won’t hurt if you can perform a factory reset. Doing so will help you determine if there’s a noticeable difference when you record a video or make a call. If you haven’t done it before, simply follow these steps:

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

The main issue about the SIM card getting disconnected may or may not be hardware-related. If nothing changes after a factory reset, make sure to have the phone checked for potential repair or replacement.

Problem #5: Galaxy S7 Wi-Fi not working properly

Hello Droid Guys! I have a Samsung Galaxy S7 and am having a few problems that I cannot seem to fix. The problems are:

– Phone will not connect to Wi-Fi

– Error message: “Cannot connect to proxy server”

However, apps still update via download even when mobile data is turned off, but apps that need internet do not work. I have tried on multiple Wi-Fi servers so I know it’s not my router. Wi-Fi has worked on this phone with no problems for several months.

What I have tried that has not worked:

– uninstalling and reinstalling Internet browsers

– doing a system reset on my phone

I hope you can help! I really don’t want to buy a whole new phone. Thanks! — Megan

Solution: Hi Megan. Firstly, we presume that what you mean by system reset is factory reset. Our question is, did you check how Wi-Fi worked right after doing a factory reset without first installing your apps back? If you did re-install your apps first after a factory reset before recreating the issue, you may have missed an important opportunity to identify the trouble maker. Consider doing another round of factory reset, then test Wi-Fi functionality right after.

There’s no reason for a new device like your S7 not to work properly unless the Wi-Fi radio itself is broken. Consider having the phone replaced if the problem returns.

Problem #6: Galaxy S7 stuck in Safe Mode after dropping it in water

Hi. I submerged my S7 Edge in a shallow pool of 1.20M for 5 seconds and the camera area fogged up, the sound was distorted and the phone went into safe mode.

Now, all the problems have been resolved – the speakers are working fine, the camera fog has cleared up but I am unable to get it out of safe mode. The option says click to disable safe mode and that the phone will restart but it still restarts in safe mode. Please help! Thanks! — Karan

Solution: Hi Karan. The new Galaxy S7 Edge comes with IP68 certification, which means that you can leave it submerged in 1.5 meters of water for 30 minutes at most. Beyond these figures, water pressure can penetrate the device’s seals and create a mess. And speaking of seals, it’s important that they are properly in place before the handset hit water or else the certification is useless. That the camera fogged up and the speaker may have been affected after the water exposure is an indication that some amount of water may have found their way into some parts of the device as well, perhaps in the contact points of the hardware buttons, causing the phone to boot in safe mode.

As you can see above, booting in safe mode involves pressing the Power and Volume buttons and any of them may have been holding some water at this time.

For an S7, you can normally disable safe mode as well by doing a soft reset by pressing the Power and Volume Up buttons for at least 10-20 seconds. If this simple procedure won’t do anything, consider doing a factory reset instead.

Should everything fail, you can assume that there’s a hardware problem that forces to boot the phone in safe mode only. Have the phone replaced.

Galaxy S7 Edge apps on edge panel not working with Wi-Fi, other issues

S7 Edge

Samsung’s latest flagship phones, the #GalaxyS7 and S7 Edge, are receiving a lot of positive praise from users and critics alike. Although majority of features of the phones are only improvements of their predecessor, it’s hard to ignore the amazing hardware they possess. But just like any other smartphone, the S7 series is not perfect and we are only starting to become aware of the issues some users have encountered with it. Below are some of these issues:

  1. Galaxy S7 not detecting some files after formatting an SD card
  2. Galaxy S7 Edge apps on edge panel not working with Wi-Fi
  3. How to recovery files from a Galaxy S7 with a black screen issue
  4. Unable to re-install a Castle Clash game on a Galaxy S7
  5. Galaxy S7 won’t turn back on after an update

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, or you can install our free app from Google Play Store.

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: Galaxy S7 not detecting some files after formatting an SD card

I recently bought a 128GB SD card (Scandisk) from EBay and it work fine when I insert into it to my phone. However, for some odd reason I thought about doing a merge internal memory into it the SD card memory this week and format the SD card.. I backed my data up prior to doing it and tried to reload everything back. That’s when I started seeing problem.

Most of pictures/files/music wasn’t showing up when i I look under my files from phone…However when I plugged the SD card back into my computer I was able to see some files. Strange. I decided to format the SD card again this time from my computer to see if that makes a difference and it did..

Also, I rename some of files/folders and did a chkdsk /f & /r command fix-up on the SD card itself. So far, I can see some of the files but not all of it..

Any suggestions, should I contact Ebay to get a replacement card…. — Elijah

Solution: Hi Elijah. Sometimes, the generic formatter software for USB devices installed on smartphones and PCs can create weird glitches.

Using a generic SD card formatter also tends to result to less than optimal performance for a memory card. If the problem is not phone-specific, then formatting an SD card differently may resolve the issue. We recommend that you use SD Association’s publicly available formatter instead to try to fix the issue. Simply follow this link to SD Association’s official site.

Problem #2: Galaxy S7 Edge apps on edge panel not working with Wi-Fi

Hello Droidguy. I purchased my Samsung Galaxy S7 Edge a few days back. For the first few days it was all good. I loved it very much.

But since yesterday i have noticed that the stock apps that have come pre-installed on the phone like Facebook, Yahoo Sports and News Updates on the Edge panel don’t seem to work on my home Wi-Fi. They just say there is no network connection. But when i operate with mobile data they seem to work fine. I am able to use all the Google Apps with my home wi-fi except for Facebook and Apps on the Edge panel. Please help me out. — Aditya

Solution: Hi Aditya. We are still in the process of collecting issues from our community and it’s the first time that we encounter this particular problem on the Galaxy S7 Edge. It will take time to know if your issue is a unique one for S7 Edges so in the meantime, we recommend that you do the basic software troubleshooting.

Wipe cache and data on Galaxy S7 Edge

A good way to start is by wiping the cache and data of the apps involved. Here are steps on  how delete the cache and data of an app in Galaxy S7 Edge:

  • Go to Settings menu and tap it.
  • Tap Device.
  • Tap Applications.
  • Go to Application manager.
  • Swipe to Downloaded or All.
  • Select the desired application and tap Clear cache and/or Clear Data.
  • Tap OK.

Refresh the cache partition of Galaxy S7 Edge

If deleting app cache and data won’t result to anything positive, the next step is to wipe the cache partition. Here’s how:

  • Turn off the phone.
  • Press and hold Volume Up, Home, and Power at the same time.
  • When the Samsung logo appears, release Power.
  • Release the other two hardware keys once the Android logo shows up.
  • Wait for access to the Recovery menu (may take up to 60 seconds).
  • Once you’re in Android System Recovery menu, press Volume Down button repeatedly to  highlight wipe cache partition option.
  • Press Power key to confirm.
  • Tap Reboot system now after the phone wipes the cache.
  • Press Power key to confirm and reboot your device.

If these procedures won’t change anything, be sure to do a factory reset (steps provided below).

Problem #3: How to recovery files from a Galaxy S7 with a black screen issue

I’ll try to be as detailed as possible though I am not a techy at all. I have a Samsung Galaxy S7 which for no reason has the black screen of death. I tried all the reset suggestions, a number of times, I found online like pressing buttons, but no change. I’ve plugged it into my PC and there seems to be photo files etc.

However I need my contacts and text messages which are not there. I have done loads of searches for solutions and am getting nowhere. I have downloaded a program to transfer the info though the USB needs debugging (whatever that is) which I can’t do with no screen.

I thought about plugging it into my Samsung Smart TV to see if I could debug that way but as I was looking to see which cable I’d need I read articles which seem I don’t think my phone is compatible with HDMI.

I have a new phone now,  a Samsung Galaxy A3 which has a nano SIM and won’t read the SD card of the S7, which has a micro sim.

Is there any advice you could give about accessing my contacts and texts please? Thank you. — Joe

Solution: Hi Joe. If your computer can still read the photos on your phone when you connect it via USB, then there’s a chance that you can still access the contacts and messages using Smart Switch. Simply install Smart Switch to your computer and connect the phone to it via USB. If Smart Switch won’t detect the phone or its contents, then you’re simply out of luck.

Kindly call Samsung to have the screen fixed, or simply get a replacement.

Problem #4: Unable to re-install a Castle Clash game on a Galaxy S7

My son plays on my phone, of course. There is a recent update to a game, Castle Clash, that I tried to update to the new version. It threw up an insufficient storage warning. So I cleared my cache, restarted my phone and still the same problem. And of course you can’t play the game without the update. So I went through my phone and moved some apps to my SD card, which will give me more storage on my phone. Went back to download the app and still gave the same notice. So uninstalled the game and tried to reinstall it and now it’s stuck on installing and won’t let me update or download anything from the Play Store.

Also is there anyway to move apps to my SD card other than just one at a time? — Demethra

Solution: Hi Demethra. The answer your question is no. You need to manually select each app in order to move each one to the SD card.

If you’re having trouble installing an app from the Play Store, your first task is to wipe the cache and data of the Play Store app itself. Kindly follow the instructions above on how to do this. If re-installation will continue to fail after wiping the cache and data of Play Store app, you also want to delete the cache partition (steps provided above).

We can’t see a reason why a new phone like an S7 won’t refuse to re-install a game but if nothing works, make sure that you factory reset it. This will ensure that any firmware bugs that may have developed after the initial set-up and installation of apps are deleted. You also want restore all app and firmware settings on the phone all at once. For reference, simply follow these steps on how to factory reset a Galaxy S7:

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

After a factory reset, try to install the game again to see the difference. If the issue persists, be sure to contact the developer.

Problem #5: Galaxy S7 won’t turn back on after an update

I have a new S7 and recently did a system update that I did NOT want to do but I accidentally hit ‘install now’ when it was in my pocket. Well, my battery was not fully charged and during the update my phone got really hot and once the update finished my phone was on like normal with about 20% battery. But then while I was on the app Instagram it froze and shut off and restarted.

Then while I was looking at my pictures and it froze again and shut off and wouldn’t turn back on using the power button. It also didn’t respond to the charger or being plugged into the computer. Also tried holding power button down and all the different resets when I was on the phone with technical support. Please tell me there is a way to get it up and running again or at least get my photos and videos off because I didn’t have them backed up. Thanks! — Melissa

Solution: Hi Melissa. There’s no way to recover files from a dead phone. The Nandroid chip that stores phone data has to be powered so it can accessed. Unless the phone boots up, your files are good as gone. If your phone won’t respond to other hardware button combinations, the most likely reason for the problem may be hardware in nature. Please bring the phone to a Samsung store so they can check the battery first. If there’s no battery issue, Samsung may have to either do further diagnostics for potential repair or replacement.
