Step-by-step guide in troubleshooting Galaxy S7 with “Unfortunately, Phone has stopped” error

This problem doesn’t only occur in the Galaxy S7 as it also occurred to previous Galaxy models. Other Android devices may also encounter this problem only that their built-in phone app may have a different name.

The error message is very annoying as you may not be able to answer calls or make one. It is, therefore, imperative you try to troubleshoot your phone to get rid of the error. But before we jump right into our troubleshooting method, here’s one of the problems sent by our reader.

Problem: Hi guys. My phone is an S7 but it’s showing “Unfortunately, Phone has stopped” whenever I try to make a call. I mean, the phone app opens but when I dial a number, the error shows up and as a result, the call won’t go through. It’s very annoying because it sometimes occur when I receive a call. Can you look into this problem and tell me what I need to do to fix my phone? Thanks.

Troubleshooting: The error message may occur under different circumstances or triggered by different factors. You just need to be observant enough to know what causes the problem because if you have such information, you may be able to fix the problem easily. That said, here’s what I suggest you do about this:

Step 1: Run your Galaxy S7 in Safe mode to know if third-party elements trigger the error

You may have installed an app that conflicts with the phone app or the firmware and that might be the reason why this error comes out. You need to rule this possibility out first because if it’s the case, it would be easier to fix the problem. Here’s how you start your phone in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

While in this mode, try to open the phone app to see if the error still shows up. If the problem is fixed, then you need to find that app that’s causing the problem and uninstall it. You may have to uninstall more than one app and reboot your phone to normal mode a lot of times to confirm if the problem is fixed. Here’s how you uninstall an app from your S7:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

if , however, the error still shows up even in safe mode, it could be just an app issue. Move on to the next step.

Step 2: Clear the cache and data of the Phone app to reset it

It might be just an issue with the app so you need to reset it before going to other troubleshooting procedures. You may lose your call logs but I think that’s fine especially if it can fix the problem. Follow these steps to reset the phone app:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Storage.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

After this, open the phone app to know if the error still shows up and if so, then move on to troubleshoot the firmware.

Step 3: Delete the system caches, some of them may be corrupt

Corrupt system caches may cause various performance issues including the crashing of some  apps. So, in this step, you need to boot your phone in recovery mode and then wipe the cache partition to delete the cache, here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition’.
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If the error still shows up after this, then you have to reset your phone.

Step 4: Backup your files and data and reset your Galaxy S7

At this point in time, it’s necessary to reset your phone as it’s clearly an issue with the firmware. So, backup your files and data, disable Factory Reset Protection and then do the reset. Refer to the steps below to know what to do.
