Fix Samsung Galaxy S6 Edge “Updating contact list” error, screen went black issue & related problems

One of the most common yet minor problems with the Samsung Galaxy S6 Edge (#Galaxy #S6Edge) after an update is the “Updating contact list…” error message, which comes out when you launch the Contacts app. While the term used is “updating,” it actually means “syncing” with your online accounts that house some of your contacts.

Now, let’s go back to the issues.


Galaxy S6 Edge “Updating contact list…” issue

Problem: I can not store or access my contacts. When I go to the Contacts Tap—the screen stays with the screen showing “Updating Contacts” with the circle spinning for hours. Nothing comes from it. When I try and store contacts through other means it just does not allow it. Please advise.

Troubleshooting: I know a couple of procedures that can fix this problem and that’s what I’m going to show you:

Turn the Master Sync off

The error is the result of a failed syncing process between your online accounts where you saved your contacts and your device. We don’t know for sure why there’s an error with the sync but one this is for sure, your phone will automatically stop the sync once it detects there’s no active internet connection. If you have contacts from your SIM card or phone memory, they will be populated and that’s the time you can turn the sync back on and it should work.

  1. Pull the notification bar and toggle the sync button off.
  2. Reboot your phone.
  3. Pull up the Contacts app.
  4. It shouldn’t be showing the updating contact list error now.

If this procedure failed, then try the next one.

Clear Cache and Data of Contacts & Contact Storage

So far, this is very effective as it will delete everything that has something to do with the contacts but there’s a catch; you will lose all contacts that are saved in your phone. If you cannot call somebody because the contacts app just won’t display your contacts, then this procedure is worth doing.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap the Contacts (and then Contact Storage).
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

I hope this helps.

Galaxy S6 Edge screen went black and won’t come back on

Problem: My Samsung Galaxy S6 Edge doesn’t want to switch on. It’s only black and have a green light when I charge it. After I remove the charger it has a blue light blinking. I tried everything I read in Google but still not working, still black and even if I connect it to my laptop, I can’t see any file from my phone. It’s working yesterday, my son played with it then watched music but didn’t have sounds. I tried restarting it and when it opened only application starting and loading sign. I got the battery drained and when I tried to charge it, still not opening, still black. Please help me.

Solution: Sounds to me like this is just a minor system crash issue. Press and hold the Volume Down and Power buttons together for 20 seconds to force restart the phone. If the screen remains black, try calling your phone to see if it rings. If it does, then it’s a screen problem and I’m referring to the hardware. You need a technician for that.

Galaxy S6 Edge rings but the screen is black

Problem: My phone is just not turning on. The battery is full. When I dial my number from another phone, I can hear it ring but I can’t get the call. The screen doesn’t display anything and also, I can’t hear any ringing tone. Please help.

Solution: Just like the previous issue, it could be just a system crash, although we could have provided more information if you also provided more info about the problem like when and how it started. I am almost certain this problem didn’t happen just that. There’s gotta be something that could have caused it.

Well, anyway, try to force restart the device. Press and hold the Vol Down and Power buttons together for 20 seconds. If the screen remains blank, try dialing your number to find out if it still rings. If so, then it’s a screen issue. Have a technician take a look at it. Now, about the ringtone, I think the device was set to silent but it’s not really that important, is it?

Galaxy S6 Edge can’t be recognized by computer

Problem: My phone was able to connect/plug & play to my PC one minute and then wouldn’t recognise the next. I thought it was because my husband updated Kies but every other device in this house can be recognised since then except mine?

I’ve read all of your troubleshooting and a lot of forums with a lot of conflicting info to no avail. Please help! Kind regards, Mel.

Solution: If your computer can recognize it however short the time is, then it’s not a driver issue but probably hardware. Try to see if the microUSB or utility port in your phone is loose. If so, that’s the problem but it could easily be fixed or replaced. If it’s not the utility port, then it must be the USB cable; try using a different one that you know works. If the problem still occurs, then it’s time you sought help from a technician.

Galaxy S6 Edge screen has blue line around it

Problem: My screen has a blue screen around it and it takes 3 taps to open or close an app and can’t get to the settings. Also forgot my pass code for my private photo album and was wondering if I can get passed the code or reset it somehow on my own. Thanks for your time!

Solution: It must have something to do with the Accessibility feature, at least, I’m certain that you can set the phone to Single Tap mode by turning it on. About the other issue, make sure Direct Access and Universal Switch are turned off. If the problem remains, then you have no other option but to perform the master reset.

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

Galaxy S6 Edge can’t play MOV videos

Problem: After being in “My files,” then “Download history,” I have the following message to open a mini video (IMG Mov.) that I sent to my email to be able to save in my phone and Google Photos. “Unable to find application to perform this action” but does not say which App do I need! Thank you for your help.

Solution: Videos with .mov file extension aren’t natively supported by Android video player, however, there are several apps that will let you play this kind of file in your phone. Two of the apps I used when I transferred videos from my iPad to my Android are VLC and MX Player. You should try them.

Alternatively, you can convert these files into a universal format like MP4. Still you need to download an app to the job for you. Choose the procedure that best suits your needs.

Galaxy S6 Edge freezes and crashes with red lines on the screen

Problem: This morning I used my phone perfectly fine, then around 2 hours later I saw that it was rebooting. With the classic reboot screen it was covered in red lines. I waited for the phone to kick back on, and it did, with the red lines still there. About a minute later the phone freezes, and crashes, and it continues to constantly reboot and crash.

Solution: I don’t know about the red lines but if your devices recently suffered physical damage, that could be the result. Freezes and crashes are often firmware related but with those lines appearing, it seems like it’s a combination of both. The only thing you can do in this case is master reset.

Warning system error message appears with green coding

Problem: A warning system error message keeps appearing with green writing and coding in the background. I have never seen this on a phone before. I do have a screen shot but can’t seem to upload the picture here. I have only been using the handset a week. Any help would be greatly received. Thanks.

Solution: It could have been very helpful to us if you included a bit more details about the error message like, you know, the actual message or just a part of it. As to the green coding, well, that’s the color of the font developers use especially in dark backgrounds. Also, we could help you better if you told us when and how it started. But try to reboot the phone or force reboot it by pressing and holding the Volume Down and Power buttons for 20 seconds. If it failed, then reset it.
