Hey guys. Welcome to our Samsung Galaxy S7 troubleshooting series and in this post I will address some of the camera-related issues owners encountered including the “Warning: Service Error Occurred. Please restart camera.” error as well as “Unfortunately, Camera has stopped.”

Read on to learn more about these errors and issues so you could understand how they occur and what could possibly fix them. I’ve provided some information on how to troubleshoot them below.

For those who have other issues, visit our troubleshooting page and see if we already addressed issues that are similar to yours. Feel free to use the solutions we suggested and if they won’t work, you may contact us directly by completing our Android issues questionnaire.

Q: “The face camera works sometimes but the back does not work at all. I have tried every method, I even resorted to hard resetting my phone, which I did. But it still didn’t work.

A: The owner also indicated she gets the error “Warning: Service Error Occurred. Please restart camera.” I understand you already did the master reset to no avail. At this point, it seems like it’s a hardware problem, although I really want to know if your third-party apps have something to do with it. That said, try booting your phone in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Now open the camera app and switch back and forth to the front and rear cameras. If the error still occurs, then it must be a hardware problem, otherwise, there’s still a chance reflashing the firmware will fix the issue, although you need a technician to do so.

Q: “The camera switch is not working so I cannot switch to the front camera for selfies.

A: We know that when our readers contact us, they often have issues with their phones. We are serious in what we do and all we ask is information…detailed information. Descriptions like “not working” doesn’t really help as it could mean a lot of things. So, what does “camera switch is not working” mean?

If it means it appears ok but won’t switch between cameras when tapped, then all you got to do is clear the cache and data of the Camera app.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch Camera.
  6. Touch the Force Close button first.
  7. Then, tap Storage.
  8. Tap Clear cache and then Clear data, Delete.

If it means that the switch actually changes the camera but you get an error, then there’s a chance it’s a firmware issue and if it started after an update, wiping the cache partition may do the trick:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If both procedures failed, then a master reset might be necessary, although you have to backup all your data before following these steps:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

Q: “‘Unfortunately, Camera has stopped’ appears when I tap the camera icon and I cannot use the camera. I’ve taken the phone to T-mobile store and they performed both a hard and soft reset to no avail.

A: While this error often refers to the camera app crashing, there’s a chance that it’s also a hardware issue. I understand T-Mobile people already did the reset to no avail but I’m wondering if they tried to restore your settings and apps after the reset. There’s a chance that other apps are also causing the problem. So, I suggest you try booting your phone in safe mode first and open the camera. Then clear the cache and data. If the problem remain, do the master reset yourself as I believe T-Mo’s techs just did the factory reset.
