Troubleshooting Galaxy S6 Edge with “Unfortunately, Contacts has stopped” error

The purpose of this troubleshooting is for us to know what the real problem with your phone is, what triggers the error and what needs to be done to get rid of it for good. So, read on for our troubleshooting steps but before that, here’s one problem that best describes this error and how to shows up…

Problem: Everytime I try to dial a number, an error shows up on my phone saying “Unfortunately, Contacts has stopped.” My phone is a Galaxy S6 Edge and this problem started just recently. I don’t really know what happened with it but I haven’t done anything that may have triggered the problem. I just dialled a number one day and then the error showed up and it kept showing up since then. I’m not really a tech person so I don’t know what to do to fix this. Can you help? Thanks.

Troubleshooting: Perhaps it’s just an issue with the app or it’s possible that the firmware is experiencing some issues as well. We need to troubleshoot the phone to be able to determine what this problem is all about and whether or not we can fix it on our own. That being said, here’s what I suggest you do:

Step 1: Clear the cache and data of the Contacts app

Let’s go after the app that’s mentioned in the error immediately. It’s a built-in app so the only thing we can do is clear its cache and data. This, of course, will reset the app but don’t worry none of your contacts will be erased. However, I would suggest you sync your phone with your Google ID so that your contacts and other personal information will be backed up. After which, try to follow these steps:

  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 Contacts.
  6. Tap Clear cache.
  7. Tap Clear data button, then OK.

If the error still shows up after this, then it’s possible one or some of the third-party apps is causing the problem. We need to confirm this that’s why you have to do the next step as it’s necessary.

Step 2: Reboot your Galaxy S6 Edge in Safe mode

This will temporarily disable all third-party apps and services, so if one of them is causing Contacts to crash, then the error shouldn’t occur in this mode. In which case, you just have to find the app that’s causing the problem and then uninstall it, although you may have to uninstall more than one app  to be able to pinpoint the culprit. Here’s how you boot your phone in safe mode:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. 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.

If, however, the error still shows up even if the phone is in safe mode, then the problem might be with the firmware. Move on to the next step.

Step 3: Delete the system caches so that they’ll be replaced

If the first two steps failed, then it’s time to go after the firmware and the first thing you should do when you reach this far is to delete the system caches so that the phone will be forced to create new ones. You need to boot your phone in recovery mode to be able to do that…

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

It may take a little longer for the phone to reboot but wait for it until it becomes active, then try to see if the error still occurs and if so, you have no other choice but to reset your device.

Step 4: Perform Master reset on your Galaxy S6 Edge

You have no other options left at this point except the reset. While it seems the error is a complicated issue, it’s actually not and reset can most probably fix it. However, you will have to go through the hassles of backing up your files and data and since we’re doing the Master reset, you have to disable anti-theft so you won’t be locked out after the reset. This is how you disable anti-theft on your S6 Edge…

  1. From the Home screen, tap Apps.
  2. Tap Settings.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap the Google ID email address. Repeat for each Google email address.
  6. Tap MORE.
  7. Tap Remove account.
  8. Tap REMOVE ACCOUNT to confirm.

After this, follow these steps to reset your phone…

  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.

If the problem still occurs after this, the firmware needs to be reinstalled so let a tech handle it for you.

Galaxy S6 Edge shows “Unfortunately, Contacts has stopped” when receiving phone calls

Problem: Hello guys. My problem may also pose a challenge for you. First off, my phone is a Galaxy S6 Edge. It always worked perfectly since last year, although I’ve already done a few factory resets since then. My problem occurs when somebody calls my number because the moment I answer the call, the error “Unfortunately, Contacts has stopped” will pop up. But the thing is, the error would only show if the one calling me is in my contacts list because if the number is unknown, the error won’t pop up. Do you guys know how to fix this? Any help will be appreciated.

Troubleshooting: Actually, your problem is very easy to understand–the error shows up when the contact you’re trying to call or calling your number is in the contacts list. We’ve actually seen this problem before and it was kind of popular with the Galaxy S3 and S5. We have just a troubleshooting method you can use to try and fix this and here it is…

  1. Clear the cache and data of the Contacts app –  just like in the first problem, you’re trying to reset the app by clearing its cache and data but don’t worry, none of your contacts will be deleted. However, there’s no harm in backing up your contacts list before you troubleshoot. If you don’t have time though, then it’s fine.
  2. Clear the cache and data of the Contacts Storage service – now, in this procedure, contacts save locally in your phone’s internal storage will be deleted. Therefore, it is recommended you sync your phone with your Google account so that your contacts will be backed up. After which, just follow the same procedure as clearing the cache and data of the Contacts app but this time look for Contacts Storage.
  3. Reboot in safe mode – after clearing the caches and data of the Contacts and Contacts Storage services and the error still shows up, then try to find out if third-party apps have something to do with it. Reboot your phone in safe mode and try to dial a contact from the list or call your number. If the error still pops up in safe mode, then it might be a firmware issue, otherwise, the next thing you should do is find the app that’s causing the problem.
  4. Wipe the cache partition – assuming the error still shows up in safe mode, you should try to wipe the cache partition so the system caches will be replaced. This procedure is as effective as a reset but it doesn’t compromise the safety of your data. It’s a necessary procedure so make sure you do it before the reset.
  5. Reset your Galaxy S6 Edge – if the previous steps failed to get rid of the error, then you have no other choice but to reset your device. However, make sure you backup your files and data as they will all be deleted and can no longer be restored after. I suggest your reset your phone through the Settings menu.

All the procedures here can be found in the first issue except the factory reset. Here’s how you reset your S6 Edge through Settings menu…

  1. From the Home screen, tap Apps.
  2. Tap Settings.
  3. Tap Backup and reset.
  4. If desired, tap the Back up my data slider to ON or OFF.
  5. If desired, tap the Restore slider to ON or OFF.
  6. Tap Factory data reset.
  7. Tap Reset device.
  8. If screen lock is enabled, enter PIN or password.
  9. Tap Continue.
  10. Tap Delete all.

I hope this helps.

Contacts app crashes when making a call on the Galaxy S6 Edge phone

Problem: Hi guys! I am hoping you can help me with my problem or if you’ve already published articles that deals with my concern, kindly point me to the right direction. Anyways, my problem is that every time I make a call to any number, there is an error that tells me about the Contacts app that stopped working. As a result, my call won’t go through. Surprisingly though, the error won’t show up when somebody calls me so it really puzzles me why this problem happens. Please help me.

Troubleshooting: While the problem appears to be so complicated and pose similarities with the first two, yours is actually easier to fix than the others. You see, the error only shows up whenever you make a call but when somebody calls your number, everything is working the way it should, right?

The error mentions the Contacts app being the one that crashes, however, it occurs only when you dial a number. This means the trigger is actually the dialer or the phone app. That said, you can get rid of the error by doing these…

  1. First, clear the cache and data of the Contacts app since it’s the one crashing. After which, try to dial a number again to see if the error still shows up and if so, then move on the next step to finally fix it.
  2. Now, clear the cache and data of the Phone app. Just follow the same steps but choose Phone instead of Contacts. This should reset the app and may correct whatever conflict is created every time you dial.

Well, if the problem still occurs after this, then reset your phone.
