Galaxy S7 lags, freezes then shows up “Unfortunately, Settings has stopped”

Problem: I hope you guys can help me with my phone. First of all, I just use my phone for text and calls and light browsing with no games at all. I’ve taken care of it since I bought it in June. For some reason, it started to run very slow and the lags occur more often then it developed into freezes. The freezes may take up to a minute before I can use the phone but even so, it’s very slow that it would take forever to open apps. Then recently, there’s an error message that keeps showing up, it says “Unfortunately, Settings has stopped” which is really kind of annoying because it pops up anytime it wants. I don’t know how to fix this problem so if you can help me that would be great. I want my old phone back, no lags, no freezes and definitely no error. Can you help me? And by the way, my phone is a Samsung Galaxy S7. thanks.

Troubleshooting: Lags, freezes and apps force closing are among the most common signs that your phone is suffering from a moderately serious to a complex firmware issue. More often than not, it’s the performance that suffers and it’s really very annoying to deal with this kind of issue. So, in this section, I will walk you through on how to troubleshoot your Galaxy S7 that keeps on lagging, freezing and crashing of apps.

Step 1: Reboot your phone if it’s the first time the problem occurs

While the error message is obviously talking about one of the most important pre-installed apps, there is always a possibility that it’s triggered by a minor system glitch. So, before doing anything, try to reboot your phone first to see if the performance improves or to know if the error still shows up and if so, then proceed to the next step.

Step 2: Restart your phone to run in Safe mode

The Settings app handles a lot of things especially user preferences for both pre-installed and third-party apps. At this point, all we know is that the phone’s performance is very slow and that this error message shows up. We will try to isolate the problem to know if it’s caused by an app and whether or not it’s a pre-installed or third-party one. We can do that by simply restarting your Galaxy S7 in Safe Mode and try accessing the Settings menu to find out if the error still shows up. Here’s how you boot your phone up in safe mode:

  1. Press and hold the Power button.
  2. When Samsung Galaxy Logo appears on the screen, release the Power button and immediately hold the Volume Down key.
  3. Continue to hold the Volume Down key until the device finishes its rebooting.
  4. Now, if “Safe Mode” appears on the bottom left corner of the screen then, you can release the Volume Down key.

While your device is in this state, continue using it to determine if there’s some improvements in its performance and of course, try to see if the error still shows up. If the problem gets fixed in this mode, then all you need to do is find the third-party apps you recently installed especially ones you installed when this problem started. On the other hand, if the error still shows up and the phone’s performance is still not like before, then move on to the next step.

Step 3: Delete the system cache by wiping the cache partition

I have a feeling that this problem started without apparent reason at all so there’s a chance that the phone updated its firmware to the latest version which gives us a reason to believe that some caches may have been corrupted during the process and need to be replaced with new ones

Here’s the thing, the caches are created by the system and we don’t have full access to each cache so we really can’t delete them one by one. However, through the Recovery Mode, we can completely wipe off the entire contents of the cache partition or the directory where caches are saved. This way, the phone will be forced to create new caches that are compatible with the new system. As long as this problem is caused by corrupt caches, the procedure below will this fix 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.

Once the phone has completely rebooted, continue observing it for signs of the same issue and if its performance is still the same, then the next step may fix it.

Step 4: Perform the Master Reset on your Galaxy S7

It is apparent that we’re dealing with a firmware issue here so if the problem remained even after wiping the cache partition, then you have no other choice but to reset your device. However, you need to backup all your data and files first before doing it because they will all be deleted and can no longer be recovered.

  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.

I hope this troubleshooting guide helps.

Error “Unfortunately, Settings has stopped” shows when uninstalling apps

Problem: The error message “Unfortunately, Settings has stopped” keeps showing up every time I try to uninstall an app. You guys said to tell you everything so here it is. My phone, which is a Galaxy S7, slowed down and I know it’s because of the apps I installed. There are so many apps in my phone not to mention that I often play game apps with it. At first, it was just doing fine, it was fast and I actually loved it. Over time, I noticed some lags and freezes so I decided to just get rid of some apps that I don’t use anymore to free up some space. That’s when I found out about the error. I can access the app manager and all but when I hit the uninstall button, the phone would freeze up for a few seconds before the error shows up. I have tried booting my phone in safe mode but the same thing happens when I uninstall an app. I tried to wipe the cache but I cannot reach the screen you’re talking about because the phone just boots up normally if I hit the Power, Volume and Home buttons. What must I do?

Troubleshooting: It could have been very helpful for us to determine what the problem is if you included the name of the apps you tried to uninstall. But that’s okay, let’s try to troubleshoot the problem based on the information you provided. You said that the error message shows up only when you try to uninstall apps and considering you’re trying to get rid of an app, it’s clear enough you’re dealing with a third-party app when the problem occurs. Uninstalling apps shouldn’t be as difficult as this but we can work around this problem. All you need to do is follow the steps below to restart your phone in diagnostic state and once the phone has entered that mode, that’s where you uninstall the apps you want to get rid of.

  1. Press and hold the Power button.
  2. When Samsung Galaxy Logo appears on the screen, release the Power button and immediately hold the Volume Down key.
  3. Continue to hold the Volume Down key until the device finishes its rebooting.
  4. Now, if “Safe Mode” appears on the bottom left corner of the screen then, you can release the Volume Down key.

Now that your phone is in this mode, try to uninstall the apps you were having issues with. We’re doing this to know if the error is triggered by the third-party apps you were trying to uninstall. If, however, the error still occurs then we might be dealing with a firmware issue here and in this case, you need to try to wipe the cache partition like in the first problem and if that fails, then a reset is necessary. However, you may lose your files and other app data so try to back them up before doing the reset.

  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.

After the reset, build your phone up from scratch and sync your accounts to restore your data and game progress.

Galaxy S7 shows “Unfortunately, Settings has stopped” when changing settings

Problem: I hope you can enlighten my mind because I’m getting an error “Unfortunately, Settings has stopped” when I change everything in my phone. I first noticed it about 4 days ago when I tried to clear the data of one of my apps but I thought it was just a simple glitch or temporary problems with some apps. However, when I tried to change any setting in my phone like change the ringtone, set the brightness or anything, the error shows up. It’s really kind of annoying not to mention frustrating because I have high expectations with this phone so if you guys can suggest a solution, that would be very helpful as I’m not really a tech person. Thanks a lot for your help.

Troubleshooting: We’re actually seeing a different variation of the first problem I tackled here. Odds are that the problem may be caused by apps that are crashing or force closing. When an app crashes, there are always conflicts between services that could affect the firmware’s operation. So if the crashes don’t stop, there’s a tendency that core services like Settings and other apps including the firmware will pop up errors to let the user know they stopped working and that something has to be done. Here’s what you need to do:

  • Restart your phone in safe mode and try to change the settings from there. It’s better you try to change the settings when all third-party apps and services are disabled.
  • If the problem still occurs in safe mode, then wipe the cache partition to delete all possible corrupt system caches. Follow the steps I provided in the first problem.
  • Reset your phone if the problem occurs even if the phone is in safe mode and after the wiping the cache partition. Just don’t forget to backup your files and data especially ones that are saved in your phone’s internal storage.
