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 S6 mutes voice calls | Galaxy S6 microphone stops working during calls

Here’s an interesting one. I got my Galaxy S6 back in June and as of October, it started muting the call on my end. I can hear everything they’re saying but they don’t hear me. The call doesn’t drop, it stays connected until one of us hangs up. It was steadily increasing based on longer conversations. I have insurance on it so I sent it away to be repaired. I received a new replacement phone and guess what! It still mutes! A completely different phone (checked the IMEI #). I have cleared the cache partition and ran in safe mode to detect if a 3rd party app was the problem but it didn’t happen while in safe mode. I don’t want to keep it that way, but this is driving me crazy! Any ideas that you haven’t suggested?

P.S. the phone I sent away, I did a hard reset and got the little Android guy dead with an exclamation above it. I couldn’t get it to turn back on for 2 hours and when it did, my security software was still detecting the singularity showing up in the background. — Gboden86

Solution: Hi Gboden86. It looks like you misunderstood what safe mode does. If your calls work normally while your phone is booted to safe mode, that is, muting does not occur, then that’s proof that one of your third party apps is causing the problem. This means that you simply re-installed the cause root cause of the issue on the second phone. Safe mode won’t pinpoint the exact problematic app though so you must manually do it yourself. This is done by uninstalling apps one by one, making sure that you observe how voice calls after each uninstallation. This is the only way to identify the cause of the trouble and if you have plenty of apps, you may have to spend considerable amount of time to be successful.

If you noticed that that problem started after installing a new app, try to remove it first to see if that is the cause.

Alternatively, you can do a reverse process by wiping the phone first via factory reset and observing how the phone behaves after you install an individual app. To factory rest your S6, follow these steps:

Turn off your Samsung Galaxy S6 Edge.
Press and hold the Volume Up, Home and Power keys together.
When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
Wait until the Android Recovery Screen appears after about 30 seconds.
Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #2: Galaxy S6 wireless charging not working

Hi and thank you in advance for any help you can provide. My phone will no longer charge despite the wireless charging units (I have used multiple ones) indicating that the battery is actually charging (lightning bolts and time to full recharge are visible… but the charge stays at 0% for several days now). I have done three soft resets (which has worked in the past) but they are not successful. In addition, my pins inside my phone are damaged, so i cannot charge in the traditional manner. Is there any other things you would recommend?

NOTE: I do not know which Android version I have, nor even how to determine that, so i just picked the first one in your drop down list. Thank you. — Jerome

Solution: Hi Jerome. Try charging the phone when it’s powered off. If the wireless charging problem continues, then it can also be an indication that the phone’s battery is malfunctioning. In this case, you have no other choice but to have the phone repaired or replaced.

Before you submit the device to Samsung or to any other relevant party for repair or replacement request, try to check if you can boot the phone either safe mode or recovery mode. If you can boot to any of these modes, try to check how wireless charging works. If there’s no difference, go ahead with repair or replacement.

Problem #3: Galaxy S6 won’t connect to any wifi network

Hi. my name is Kyle and I have a Galaxy S6 active. The issue that i want to bring up is that my phone is unable to connect to the internet/router. I’ve tried inputting the WEP key in several times, caps and with no caps. I gave up on this tactic, and i thought of using the WPS button on my router, while having the phone ready for pairing to it. It acted like it didn’t see the device, although i have other devices connected to it.

I’ve also tried using other routers from friends’ houses, no luck. Maybe i accidentally have something on that’s preventing me from connecting to any routers.

A few days ago it was working. (I only use phone for wi-fi). Let’s get the main bullshit out of the way so i don’t have to wait on you texting me back with the standerd questions.

No power saving bullshit is on.

Airplain mode anit on,

Bluetooth is off

Mobile hotspot off.

Yes tried turning off phone, with and without down key.

Tried forgetting wifi password, and redoing it (waiting 10 seconds to turn wifi back ok) and no I’m not resetting phone to factory format. — Player1down

Solution: Hi Player1down. If your phone is unable to connect to multiple separate wifi networks, the cause of the problem must be one of the following:

a bad app
an unknown software glitch
an unknown hardware malfunction

To check if an is to blame, you must boot your phone to safe mode. Safe mode blocks third party apps and services from running. If one of the installed apps is the cause, the issue should not occur while wifi is enabled. To boot to safe mode, follow these steps:

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.

If nothing happens when you boot to safe mode, that is, wifi remains problematic and won’t connect, do a factory reset. Here’s how to do it:

Turn off your Samsung Galaxy S6 Edge.
Press and hold the Volume Up, Home and Power keys together.
When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
Wait until the Android Recovery Screen appears after about 30 seconds.
Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

If you don’t want to do a factory rest, have the phone repaired or replaced.

Problem #4: Galaxy S6 won’t turn back on unless put in a freezer

I have a Samsung Galaxy S6. It got an update and apparently had glitches in it per Samsung and AT&T. It has made my phone not function. It will not turn on unless I put it in the freezer for 20 to 30 minutes. I spent months and months researching and found somebody with the same phone in the same problem they said they took it to a technician and the technician was able to get the device to power up by putting it in the freezer. (To get data), I gave it a shot and it worked. So that’s how I have been turning on the phone now. Problem is I want to figure out why I can’t just power up the phone normally anymore. I have hard reset, soft reset and I am back on stock firmware. Once the phone Powers up it seems to work absolutely perfect besides the fact if it turns off or I turn it off it will not power back on without the freezer. Can you please help me I’m totally stumped. — Bouncebackcutt

Solution: Hi Bouncebackcutt. If your phone shuts down on its own and won’t turn back on unless you cool it down by leaving it in a freezer, the reason for it may be overheating. Smartphones, like regular computers, are designed to power down if the internal temperature goes beyond its designed heat threshold to prevent damaging components. An overheating device won’t turn back on unless the internal temperature does back down to normal. If this keeps happening, it means that there’s a deeper hardware problem causing it. One of the motherboard’s transistors may be malfunctioning, or any other component like the battery may not be working properly. Such case cannot be solved by doing software hacks. That’s the reason why soft reset, hard reset, and flashing back stock firmware did not help at all. If the phone is still covered by a warranty, make sure that you have it repaired or replaced. If our hunch is correct, the motherboard may need to be replaced, which means that you are better off with a replacement than repair.

If the phone is no longer in warranty, you’re out of luck as that means that you will have to shoulder the repair or replacement cost.

Problem #5: Galaxy S6 can’t connect to the internet, mobile data not working | Galaxy S6 cellular network not working

Hello. i have a Samsung Galaxy S6 and when i try to use mobile data, it is just not working. I went to Settings>More networks>mobile networks. but only three options pop up on the screen: “mobile Data,” “network mode,” and “network Operators.” I don’t see the “APN” settings. How can i fix this problem becuase without it i cannot use mobile data?

It seems that the problem is because the phone is missing that configuration, so if there is a solution please help me out. I bought this phone in the US and had it unlocked in Ecuador (South America) where i currently live, and the company carrier worked out fine, though i never used mobile data until i decided to give it a try while deployed here in Iraq. i just got a phone card from a local phone company here in Iraq called Zain, and i am trying to use mobile internet to contact family. Thank you so much for your help. — Cristhian

Solution: Hi Christhian. Assuming your phone has indeed been network unlocked, that is, its original software has been modified so it can work with other network carriers, there are other factors that you should consider.

GSM vs CDMA. Smartphones, like the Galaxy S6, are not universally compatible with all networks around the world. Samsung builds phones with the carrier’s network specifications in mind. For example, not all Galaxy S6 phone models are compatible with Verizon network in the United States. When Verizon orders Galaxy S6 units from Samsung, the latter must ensure that delivered units must be compatible with Verizon’s network, which means that the phone must be a CDMA device. The same is true for AT&T phones, only that they must be GSM devices.

GSM phones can be relatively easy to reconfigure so it works in another GSM network. As long as the device has been network unlocked, a GSM phone can work in another network as long as you insert an active SIM on it.

The same is not true however if you have a CDMA phone, like one from Verizon. CDMA devices, like the ones from Verizon, are notoriously difficult to configure. In most cases, you can’t use a CDMA phone to another CDMA network, like using a Verizon phone in a Sprint network. Using a CDMA phone in a GSM network may not work all the time.

Hardware configuration. Another factor to consider is the hardware configuration of your phone. Each phone model, targeted to a certain network operator, has a specific network chip installed to allow it to work only in a certain frequency range. For example, a Verizon Galaxy S6 (128GB model) can only support the following frequencies:

LTE Band 13/4/2 (700/1700/1900 MHz) out of box;

LTE Band 3/5/7 capable (1800/850/700 MHz);

CDMA/1xEVDO Rev. A (800/1900 MHz);

Global – EDGE/GSM (850/900/1800/1900 MHz), HSPA/UMTS(850/900/1900/2100 MHz)

This means that the phone’s hardware is limited to working with the frequencies above. If the operating frequencies of the current carrier in Iraq are incompatible with your phone’s, there’s nothing that you can do about that. This may be the reason why the APN settings on your phone does not appear. Usually, APN settings are automatically configured in phone once an active SIM card has been inserted. If your phone does not recognize the SIM card, or it doesn’t show any network signal, that’s a sign that your phone cannot work with that carrier.

Problem #6: Galaxy S6 screen stopped working | Galaxy S6 won’t charge

Hello. I just wanted to complain about the S6 and see if you feel the phone is garbage. I had the S5 for 2 years. Flawless phone until the end. Towards the end it would turn off. I think that may have had something to do with space. Now that I have deleted most stuff off it, it is fine. Anyhow, I upgraded to the S6.

I wanted the S7 but couldn’t afford it at the time. 3 weeks after I got the phone, I plugged it in to charge. After a little while I went to check my phone and the LCD screen was bleeding. Within 36 hours, I could not see my screen at all. I have an old account that has a balance on it with Verizon. Because of that old account, they would not honor the warranty. Then they tell me it wouldn’t matter because bleeding screens are not covered. I called Samsung. Their warranty, you have to schedule a tech to come look at your device. It takes up to 11 days. What kind of garbage is that?

So I was forced to file an insurance claim. $150 for a new phone. Now mind you, I did not drop my phone, did not push too hard on the screen and did not get it wet. Even the guy at the store said it looked brand new and should be covered. So, there’s one issue.

Now here I am, 3 weeks later. I cannot charge my phone. Says battery too cold to charge. Are you kidding me?! The phone is not too cold, no lint in the charging port, and I did not get my phone wet. My phone is my lifeline, So I am careful with it. I do not abuse my phones! So here I am again needing to replace a phone. Thank goodness Asurion will honor the warranty. Verizon sure won’t, because of the old bill. I find that slightly ridiculous because my main account is in good standing and paid every month for several years. The one that I am behind on was a case of being too nice and somebody taking advantage of my good graces. Will never do that again.

So, could you please tell me what you think? What is the problem with the S6? I feel that maybe Samsung should take them off the shelves. I thought I loved Samsung, now I’m thinking I should have gone with a different phone. Different brand. Thanks for your quick response. — Erin

Solution: Hi Erin. If we consider the millions of working Galaxy S6 around the world, having some users report defective S6 units can almost be expected. We’ve received sporadic reports of isolated extraordinary cases but none was similar to yours. Based on our own experience with Samsung phones, from the low end ones to flagships like the Galaxy S series and Galaxy Note series, screen problems are some of the least common. Luck, or the lack of it, may be the reason why you have a malfunctioning Galaxy S6. We can confirm that your problem is not true for millions of other Galaxy S6 out there. You may have simply received a lemon. We understand that telling you to get a replacement may be easier said than done but it’s the only reasonable solution that we can suggest. A broken screen cannot be fixed by a software hack obviously so fixing it on your level is out of the question. Sure, there are many S6 problems, majority of them unreported, but the same can be said of other smartphones like iOS devices as well. In general, again considering the millions of S6 phones in service today, the Galaxy S6 is a reliable flagship device. It’s not perfect though so there may be anecdotal reports about isolated problems like the one you experienced. But then again, that’s one of the main reasons why warranty exists in the first place. There’s no perfect manufacturing system and somewhere along the way, a few hundred or thousands out of a million may have a defect when they leave the factory. Have the phone replaced and save yourself from more trouble.

Problem #7: Accidentally dropped Galaxy S6 edge screen won’t turn on | Galaxy S6 won’t power back on

Good day. I have a Samsung Galaxy S6 edge. It has been with me for only a couple of months. It was never dropped in water; however, I dropped it a few times. There is some screen damage but the phone was still in full working condition. I never had any problems with my phone because of the screen. It was still working yesterday afternoon. I was busy on my phone and eventually it just froze and rebooted by itself. I waited for the phone to reboot and when I continued working on it, it froze again but this time not turning of at all. I left it for the night hoping the battery would run flat and turn off. This morning I plugged my phone in to charge and wait a few minutes. I tried switching the phone back on, and it came on. As I swiped the screen so I could enter my phone it froze again. When the screen went black, I heard messages coming through. After a while, I checked my phone but this time it is not doing anything. The notification light keeps on blinking but when I press the home button, it does not switch the screen back on. I tried switching the phone off but nothing happens. I am concerned about this problem. Please can you help? Kind Regards. — Natasha

Solution: Hi Natasha. The only software hack that you can try is to see if the phone will turn on to other modes. If it doesn’t, you really have to seek help from a professional so the hardware can be physically examined. Keep in mind that unnecessary shock from accidental drop can both have short-term and long-term negative effects. In some cases, a dropped smartphone may not work right away while others can keep the appearance of working for some time, depending on the extent of the damage. If you did not do anything drastic on the software before noticing the problem, the cause of the trouble right now may be the long-term effect of that drop. Because diagnosing a hardware problem requires solid electronic knowledge and special tools, make sure that you let a trained technician do the job for you. Before you do that though, make sure that you try to restart the phone to alternate modes.

For reference, there are the steps on how to restart your S6 to different Android boot modes:

Boot in Recovery mode:

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

Boot in Download Mode:

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

Boot in safe mode:

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