Galaxy S7 keeps showing “Unfortunately, Settings has stopped” then freezes

Problem: Hi guys. I have an issue with my S7. There’s an error that keeps popping up randomly and when it does show up, the phone freezes for a minute or two and when I tap the OK button on that small window that pops up, I can use my phone again until it shows up again and cause the freezing. The error is “Unfortunately, Settings has stopped” which I think started after the Nougat update I downloaded and installed a couple of days ago. Can you help me please?

Troubleshooting: The error message “Unfortunately, Settings has stopped,” while it basically tells us about an app that crashed, shouldn’t be taken lightly. And basing on what our readers told us that his phone freezes whenever this error shows up, there’s a chance that the phone is suffering from a serious firmware issue that affects the overall performance.

The Settings apps is a very important app in your phone as it embraces all other apps and features and their respective settings. It’s responsible in holding information about your preferences and implementing it whenever you use a certain app, service or feature. When it crashes, most likely all other apps will be affected as well and that might be the reason why the phone is freezing when the error shows up. That being said, here’s what I suggest you do in a bid to fix the problem and get rid of the error message:

Step 1: Reboot your phone in safe mode and continue using it

The purpose is to observe if the error still shows up even with all third-party apps temporarily disabled. Since Settings embraces all apps, there’s a chance that the problem is triggered by a third-party app you installed or sideloaded. Booting in safe mode will temporarily disable those apps and if the problem is indeed caused by a third-party, then the error won’t show up in safe mode. This is how you boot your Galaxy S7 in safe mode:

  1. Press and hold the Power key.
  2. When Samsung Galaxy S7 logo appears, release the Power key and immediately hold the volume down key.
  3. Continue holding the Volume Down key until it finishes its rebooting.
  4. When “Safe mode” appears on the screen immediately release the Volume Down key.

If the error won’t show up when in this mode, then it’s confirmed one of the third-party apps, or even more, is causing the problem. You need to find that app and uninstall it while the phone is still in safe mode, however, it’s easier said than done as it’s not actually that easy to determine if a specific app is causing the problem. So, while in safe mode, try to use third-party apps you usually use just to try to trigger the issue. This may take several minutes depending on the number of apps you installed on your phone.

If it’s easier and quicker for you to just backup your files and data and then do the reset, then I suggest that’s what you do to save you from a lot of trouble. This is how you reset your phone through the Settings menu…

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

However, if the error still shows up even in safe mode, then it might be an issue with the firmware.

Step 2: Delete the system caches so they’ll be replaced

Since the problem started after an update, it’s possible some system caches got corrupted and if so, all you need to do is to wipe the cache partition and this is how you do it:

  1. Turn off the phone.
  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.

This will delete the caches but none of your files and data will be lost so you don’t have to make a backup if it’s too much of a hassle for you. If the error still shows up after this, however, then you need to do the next step.

Step 3: Perform the Master reset on your Galaxy S7

At this point in your troubleshooting, you need to make a backup of your files and data you don’t want to lose and then do the reset. You’ve already done the basic troubleshooting to no avail that’s why it’s time to just go with the reset.

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

If the error still shows up after this, visit a tech and then have the problem taken care of.

How to fix Galaxy S7 freeze and reboots issue

Problem: I turn my Galaxy S7 off then turn it back on. It takes a minute to come back on. When it does it freezes for a few seconds then shuts itself off again and takes at least 2 minutes to come back on. Whats causing this?

Solution: Even though Galaxy S7 can be considered as one of the best and fastest devices in the market today, it’s not a guarantee that you won’t face several issues such as freezing and lagging. One of the possibilities that the device are having these problems is because the firmware may be crashing. On the other hand, if the battery is defective and could not provide the required power to the system that is one of the factors that the device will restart without a warning. Here are the procedures that will help you fix the issue.

Step 1: Connect the device to the charger

To verify if the battery is defective or not, connect the device to its charger. After you connected it leave for 15-20 minutes and see if the charging icon shows on the screen. If not, try to use another charger and USB cable and see if the device is responding. If so, then the battery is fine and most likely it is a firmware related issue. For further troubleshooting, follow the next procedures.

Step 2:Perform force reboot on your phone

One of the most effective ways to fix issues like this is by restarting your phone. Through force reboot all unclosed apps and other processes that runs in the system that caused the issue to occur will be closed. To do this, just press and hold the Power and Volume Down keys at the same time for 10-15 seconds until the device reboots. After the procedure, observe closely if problem still happening, if so, you can perform the next step.

Step 3: Boot in Safe mode to isolate the problem

Since, we are not sure what really caused the device to freeze and reboot, this method will help you identify if one your downloaded applications triggered it. While in Safe mode try to observe if the issue is happening. If not, then obviously it is an app that caused it. You can uninstall those suspected apps until the problem is fix. To reboot in safe mode, follow these steps:

  1. Press and hold the Power key.
  2. When Samsung Galaxy S7 logo appears, release the Power key and immediately hold the volume down key.
  3. Continue holding the Volume Down key until it finishes its rebooting.
  4. When “Safe mode” appears on the screen immediately release the Volume Down key.

Step 4: Wipe the cache partition of the device

By deleting the cache partition you are bringing back the cache directory of the device to its factory default. But unlike in factory reset the device will only delete all files stored in the cache partition so that the device can create newer files that could run smoothly in the system. Follow the steps on how to wipe the cache partition above. However, after wiping the cache partition and the issue is still the same you can perform the next step.

Step 5: Perform Master reset procedure in your phone

Well, if all procedures you performed doesn’t fix the issue your last resort is to reset your device. The purpose of resetting your phone is to delete all files and data in your device and also to bring back it’s firmware to default settings. But before doing so, try to backup all your important files because all of it will be deleted. To master reset, follow 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.
  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. 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.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
