Problem #1: How to recover files from a Galaxy S6 with a defective screen

Screen doesn’t work and I want to get some files off the phone. However, the OS now defaults to Charging Only when you connect a USB cable & since I can’t use the screen, I can’t change it to File Transfer. In an article in October, you said “use Kies to extract whatever data you want”. Samsung doesn’t make Kies anymore and the S6 models don’t support it. Samsung redirects to Samsung Smart Switch instead, but it needs the phone to be in File Transfer mode and I can’t do that because of the screen. The phone is in USB Debugging Mode — I did that from the boot menu — but it hasn’t helped. Please don’t recommend Android Data Recovery because it’s a joke. It doesn’t work for anything above S5 and it also tells me to use my screen to get their connection to work. — Erin

Solution: Hi Erin. It appears you’ve already everything that can be done on a user level. Frankly speaking, there’s nothing more that can be done to resolve your issue. You either need to have the screen replaced first, or accept the fact that your files are gone. There’s no hardware hack to access the phone’s internal storage device just like what they do in movies (none that we know to be legal anyways). Even sophisticated hackers may find the task difficult to start with. Law enforcement agencies may have a way to do it but their tools are not for public consumption. So far, we’re not aware of any tool that’s available for the public that can be utilized to do what you want. There may be third party companies that can do the task but the price may be prohibitive. It’s not everyday that people wants to have their files recovered so effective third party services are expected to cost much. If money is not an issue, use Google to search for reliable services.

Problem #2: Theme changes behavior after Galaxy S6 was updated to new Marshmallow version

After performing a recent software update (not sure which one but I was already on Marshmallow beforehand), my theme is no longer displaying correctly. The theme is meant to put each app icon into a standard sized circle but this is not happening, the app icons are showing in their native form.

All other elements of the theme appear to be working correctly.

I’ve tried uninstalling the theme and reinstalling it with no luck. Have also reset my phone. Also tried downloading a different theme with the same feature and again, all elements of the theme work correctly APART from putting the app icons in the standardized circles.  — Adam

Solution: Hi Adam. We have no idea what theme you’re having a problem with but a good first step for you is to contact the developer of said theme. The developer may have changed something in order for the theme to work with the new Marshmallow version. Getting direct assistance from the developer itself is the only way to go for you.

Problem #3: Galaxy S6 unable to make a call when not in 4G network

Hi. I need your help. I have been having a problem with my phone for months.

I bought it in the UAE and put in different sim cards because i travel a lot and both while roaming or not, when i try to make a call it just says “call end” without ringing.

 i can send texts and receive calls, use 2g/3g/4g data no problem.

 only thing i noticed is when i’m connected to a 4g network, i can call but there are rarely places where i can get 4g so i need to fix this problem asap.

I got new sim cards because the provider thought it’s a sim problem but then it didn’t work again.

Do you have any idea what’s the issue?

I even went to Samsung and they advised me to reset my phone but I’d like to know if there’s any other way or even if reseting would fix the issue?

Best Regards. — Martina

Solution: Hi Martina. First of all, the best party that can help you or anyone with a call-related issue is the carrier. Whether it’s a SIM card issue, a phone issue, or even a software issue, it’s part of their service to ensure that voice calls work as expected. They have handy information that we don’t have so the best that we can do to help is speculate and offer generic troubleshooting and solutions. Call issues involves many factors including network-related ones so they are in the best position to diagnose where the trouble lies.

As far as solutions are concerned though, all we can tell you is to check the phone part. We suggest that you do the basics like wiping the cache partition, booting in safe mode, or doing a factory reset. All these three are aimed at checking if an app or firmware is to blame. They won’t resolve the problem if the issue is on the network to begin with.

For reference, here are the steps on how to do the solutions we mentioned.

How to wipe the cache partition of an S6

Wiping the system cache is useful if the issue is caused by a corrupted phone cache.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.


How to boot an S6 in safe mode

You want to restart the phone in safe mode if you think that one of your apps is to blame. While a solution in itself, it should give an idea whether or not your hunch is correct. If the issue fails to occur while the device is in safe mode, that’s a confirmation that indeed, one of your apps is responsible.

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.


Restore the phone to its default settings

Finally, if the first two procedures won’t help, don’t hesitate to wipe the phone by performing a factory reset. Here’s how:

  • 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.

Again, if nothing works, make sure that you call your wireless carrier again for a resolution.

Problem #4: Galaxy S6 power button is stuck and phone won’t turn on

Hi. I was having a problem on my phone and started to browse the internet hoping I could get a quick fix. I saw your page about Samsung S6 common problems and errors. I wish you could give me some advice on what to do.

What happened was my phone suddenly stopped working. I mean I was just browsing and it suddenly turned off. It was full charged though. i tried pressing the power button but it won’t start. I tried plugging in my charger but nothing happened, like no red light which indicates that it’s charging. I tried pressing again the power button for like 10-20 seconds but still nothing happened. And then while doing so, another problem came in, the power button got stuck. 🙁 tried to plug in my phone to my computer, it still gave me a black screen but I heard a sound like when you plugged in a device. I know I could just go to the service center but I would like to try fixing it first. Any advice will be appreciated. 🙂 — Valerie

Solution: Hi Valerie. That a hardware button is broken should be enough reason to bring the device to a shop. A stuck power button can prevent the phone from turning on or off properly. It may even be the reason why the device no longer boots up at this time. With the said button stuck, you can’t obviously do the basic software troubleshooting since the phone no longer powers on. There’s just no point in waiting at this time. Your best chance at resolution is to have the device physically checked and repaired. Better still, try calling Samsung to see if they can repair it themselves.

Problem #5: Unable to flash firmware via Odin after Galaxy S6 fails to turn on

I am helping a friend with his phone. His S6 stopped booting up normally and after many attempts to fix the problem without flashing, it still does not boot properly. When the phone boots turns on it goes to a screen with the android logo, the top left has “could not do normal boot” and underneath the logo it says “Downloading… Do not turn off target!!” I downloaded odin 3.11, the samsung driver, and the proper firmware. I put the device in download mode and plugged it in to my windows 10 computer, but it will not recognize the device. I have tried deleting the samsung drive and reinstalling it. I have tried using Keis. I have also tried an older version of odin and sumsung driver. No luck. Any help would be appreciated on how to get my computer to recognize my device. Thank you in advance. — Nicholas

Solution: Hi Nicholas. If the phone does not respond to flashing via Odin mode, try wiping the cache partition or doing a factory reset via recovery mode. Any of these two should fix the issue. Kindly refer to the steps provided above.
