Problem #1: Galaxy S7 bad voice call quality

I have terrible phone call quality. I have called T-Mobile for months, have received a replacement phone, and still have the same issues:

  1. crackling phone quality on both my end, and, on the end of the speaker. They can’t hear me well and I can’t hear them well.
  2. dead air appears during calls (i.e. people are speaking and the sound disappears)
  3. I have a cell tower in my house, to prevent dropped calls, and the calls continue to drop.

I didn’t have any of these issues when I was on the same carrier with the Note 3. — Colleen

Solution: Hi Colleen. An issue like yours can’t be a phone issue since you’ve already received a different unit. It’s still worth checking though if the same issue occurs if you insert your SIM card to another phone. If the issue remains, that’s a confirmation that there may be a network issue that must be addressed by T-Mobile first. We don’t think doing software troubleshooting will do anything either since situations like this can only be resolved by a carrier.  The most that you can do on your end is factory reset. If the issue remains even with clean software, call T-Mobile again and ask for more assistance.

For reference, here are the steps on how to do a factory reset:

  • Turn off your Samsung Galaxy S7 or 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.

Problem #2: Galaxy S7 won’t play videos from SD card

I store all photos and videos on my mounted SD card. I have been having trouble playing back videos recently. Today I copied a video to the device memory. I tried to play the video from the SD card file and the video froze within the first 3 seconds but audio continued. I tried playing the same video with from the device copy of the file and it plays fine without freezing. I tried this with multiple files and they all were the same, issue when playing from SD card but no issue playing from device.

Please help as this is exceptionally frustrating and the work around is just plausible for the long term.

Also, it seems as though everytime I access files on the memory card it’s exceptionally slow to load the directories etc. Thanks so much in advance for any help you can provide. — Craig

Solution: Hi Craig. We can’t see you mention using a different SD card so you must do that first. This is an obvious troubleshooting step which you should have done before contacting us. Keep in mind that any SD card can go out of order for a lot of reasons. An SD card can get corrupted anytime, or files go corrupt for other reasons. If the SD card you’re using is a recycled one, that is, it’s been in other devices before for some time, you can safely assume that age and wear and tear may have taken their toll.

If the issue lies on the current SD card, this problem should not occur if you use a different one. If the same problem happens even if you keep the file in the a different SD card though, the cause may be phone related. Try to wipe the phone’s cache partition first and try to play videos again. Here’s how it’s done:

Minor firmware and hardware glitches can be fixed by deleting the system cache. In fact, we technicians always recommend doing it before performing any of the reset procedures:

  • Turn off your Samsung Galaxy S7 or 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 cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ 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.

If there’s no apparent change after a cache partition wipe, the next logical step is booting your phone in safe mode. Enabling safe mode is an efficient method to see if a problem is due to a third party application. Here’s how it’s done:

  • Turn your Galaxy S7 Edge off.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7 Edge’ 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.

If nothing works still, consider doing a factory reset. Kindly refer to the steps above.

Remember, the issue can only either be the SD card or your phone. Make sure that you isolate which one is the cause of the issue first.

Problem #3: Galaxy S7 Wi-Fi is not working

My Wi-Fi wasn’t working. it keeps not letting pic shoe up I turn wifi off and on. It will work for a bit then do it again slow and say no Internet even though it says I’m always connected. It also keeps sending me tons of Facebook and email notifications. At one time, even when seen it not the time it should be acting like wifi just picked up when phone I’d on sleep mode.

Also, I feel like when go to phone when it wake up and still on wi-fi it won’t work good, it’s slow and act like there is no Wi-Fi. I have never had bluetooth and I only have 2 apps I downloaded. It is a new phone and I factory reset it twice. Got it month only ago. Talked to Verizon 3 times now they can’t figure it out. They’re saying i don’t want a new one in case does the same with wifi not working properly.

please help me. I did it all safe mode and all nothing. Did new updates there is no new one since the July update. I’m at lost for words since 800 dollar phone and unhappy and stuck with it. I’m furious. — Samsung user

Solution: Hi Samsung user. Before you contemplate on having the phone replaced, you must do an important troubleshooting step first, which is to connect your phone to another Wi-Fi network. We haven’t seen you mention it in your problem description above. The purpose of this troubleshooting step is to know if your phone only encounters said problems when you are connected to your own Wi-Fi. There’s a chance that your own Wi-Fi network is problematic. In other words, the issue may not entirely be due to a faulty phone but rather one that lies within the Wi-Fi network itself. Needless to say, you have to make sure that you Wi-Fi network is reliable and does not have intermittent internet connection. Remember, even if Wi-Fi connection status says “connected,” that doesn’t mean that the internet connection on your device is okay. The “connected” status is just an indication that your S7 is talking to the local router but not beyond it, which is the internet. For all you know, the router itself is not communicating to your internet service provider, or may be doing it poorly, causing internet connection to be spotty at times.

If you don’t know how to troubleshoot your Wi-Fi, contact your internet service provider (not your cellular provider) and ask them for support. Doing this is important, especially if your S7 works just fine when connected to other Wi-Fi networks.

If you observe the same problems even after connecting to a known, working Wi-Fi network, consider having the phone changed as you may have a bad Wi-Fi radio.

Problem #4: Galaxy S7 Wi-Fi won’t connect and keeps showing proxy server error

Hi guys. I have a Galaxy S7. Got it brand new out of the box about 2 months ago. Early in May this year I changed out my modem/wireless router combination to a Netgear Nighthawk which is also a modem/wireless router combo. All of my devices, the S7 and my iPad and iPod, have had no connection issues w/ the new router at all. it was a seamless change.

About a week ago, almost 3 months later, my S7 started acting up. It shows connected to my wi-fi, as it always has, but it won’t connect to the internet. It keeps giving me proxy server errors, but it is connecting to the wi-fi at my workplace so I know it is still able to connect to a wifi source and connect to the internet.

It may be worth mentioning that my iPad and iPod are experiencing zero problems on my home’s wifi so it’s tough for me to believe it’s my router.

And also, I have made no changes to my router’s settings so everything, to my knowledge, is the same as it was when the S7 was working properly. So far I have tried using different browsers but all give the proxy server errors or say my wi-fi is offline.

If you guys have any ideas or can put me on the right path to a solution I would be very grateful. Thanks in advance for your time and attention. — Richard

Solution: Hi Richard. If you are 100% positive that there are no Wi-Fi changes prior to the phone started acting up, then the issue may be isolated to your S7 only. You may have installed some updates or apps that changed how the operating system handles Wi-Fi functionality. The first thing that you want to try is wipe the cache partition. If that won’t change anything, the next step is to boot the phone in safe mode so all third party apps and services will be prevented from running. This will help you check if one of them is the culprit.

You also want to ensure that the smart network switch is not the problem. If you have it enabled, try to see how Wi-Fi behaves when it’s turned off.

Finally, if nothing appears to work, don’t hesitate to do a factory reset.

All the steps on how to wipe the cache partition, boot in safe mode, and do a factory reset are provided above.

Problem #5: Galaxy S7 is not responding | Galaxy S7 won’t turn on

Hello!

I apologize for contacting you about a question that you have undoubtedly been asked a million times before, but I’m at a loss for what to do. I have an S7, Android phone that for whatever reason won’t turn on. What’s strange is that the problem appears to have started with the camera. I had it open when suddenly the screen stopped working. At first I thought it had been a charge issue, so I plugged it in. When I went to reboot the device it worked for a whole of 5 seconds before I once again decided to use the camera, and I haven’t been able to fully turn the phone on since. At that point the battery was at 18%.

Now normally, when I have these issues I would go to my phone carrier given that my phone is only 7 months old and I’m still covered under warranty. Except. My phone carrier is in Canada, and I’m currently between Germany and Denmark for the next 6 months. I’ve put the phone in a bag of rice on the crazy chance that my water-resistant phone happened upon a water problem. Any suggestions for booting it? Or should I just find a Samsung store and hope for the best? Thanks. — Karlene

Solution: Hi Karlene. Is the phone completely unresponsive, that is, the screen remains black and it doesn’t sound or vibrate when turning it on? If yes, then the problem can be caused by one of these things below:

  • bad charging port
  • faulty battery
  • bad USB cable
  • broken power button
  • software glitch

If you noticed, the first four items in this list are all hardware, which all needs to be checked. Try using another USB cable and charger and leave the phone connected for at least 30 minutes. If the issue remains, try to see if you can boot the phone to other modes like safe mode (steps provided above), recovery mode, or download mode/Odin mode. To boot in recovery mode, follow these steps:

  • Turn off your Samsung Galaxy S7 or 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.

To boot in Odin mode, simply replace the Volume Up with Volume Down keys while doing the rest of the steps like in recovery mode.

If your phone remains unresponsive after trying to boot to any of these modes, there’s nothing much that you can do on your end. You must find a third party repair center so they can check it for hardware errors.

If, on the other hand, the screen remains black but the phone still vibrates or makes a sound, it’s possible that the issue is isolated to the screen only. Screen replacement should fix the problem easily.
