Samsung Galaxy S7 keeps showing “Unfortunately, Calendar Storage has stopped” error [Troubleshooting Guide]

There is a Calendar app on your #Samsung Galaxy #S7 and there’s also a Calendar Storage service. The former is actually the interface you can use to save events and other calendar entries while the latter is the service responsible in managing your entries. In other words, it’s the one storing those entries, hence then name.

The error message actually tells us about the service that stopped working for some reason. We will try to look into this error to know what caused it. Based on similar issues we addressed before, it could be that the cause of the problem is the Calendar app or it could be another service depending on the app you use when it popped up.

Troubleshooting Galaxy S7 with “Unfortunately, Calendar Storage has stopped” error

The Calendar Storage service always runs in the background and it must work perfectly with the Calendar app as well as other apps that have access to calendar events and entries. One of them may have caused this service to crash or it could be that the firmware itself has some issues. This troubleshooting guide will help us find out what the problem really is and what needs to be done to fix it. But before I give you the steps, here’s one of the messages our readers sent us about this error:

Problem: Hello droid guys. I have a problem with my phone and I hope you can help me with it. First off, my phone is a Samsung Galaxy S7. It’s an upgrade from my old S5 and since I got it last year, I only had a few issues with it and this error is just one of them. The error keeps popping up saying “Unfortunately, Calendar Storage has stopped” and it shows up randomly. I’m not sure what I have to do with it so please guide me. Thanks.

Let’s now jump to our troubleshooting steps..

Step 1: Clear the cache of the Calendar Storage service

This procedure worked for previous Galaxy models that also encountered this error message. It basically just deletes the cache that the firmware created for this service. None of your settings or calendar entries will be deleted so it’s safe…

1. From Home screen, tap App icon.
2. Tap Settings.
3. Tap Applications and Application manager.
4. Swipe to ALL tab.
5. Find and tap Calendar Storage.
6. Touch the Force Close button first.
7. Tap storage.
8. Tap Clear cache, Delete.

After clearing the cache, try to see if the error still pops up and if so, the next step might help.

Step 2: Clear the data of Calendar Storage service

If the clearing of the cache didn’t fix the problem, then it’s time you cleared the data. However, before you do that, make sure you sync your phone with your Google account to backup your calendar entries, then follow these steps:

1. From Home screen, tap App icon.
2. Tap Settings.
3. Tap Applications and Application manager.
4. Swipe to ALL tab.
5. Find and tap Calendar Storage.
6. Touch the Force Close button first.
7. Tap storage.
8. Tap Clear data, Delete.

You may have to sync your phone again to download calendar entries from your account. If the error still shows up after this, then try to see if one of your apps is causing the problem.

Step 3: Reboot your Galaxy S7 in Safe mode

Starting your phone up in Safe mode will temporarily disable all third-party apps and services. One of them maybe causing this problem so we need to run the phone with only built-in apps and services running in the background. If the error is still showing up and it might be an issue with the firmware, otherwise, you just have to find the app that’s causing the problem and then uninstall it. This is how you boot your phone 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.

Step 4: Delete the system cache through the Recovery Mode

System caches often get corrupted during firmware updates so there is a possibility that this problem is due to some corrupt caches that are still being used by the new system. The thing about caches is that they can be deleted without adverse effects on the performance of your device, ironically, deleting them from time to time especially after firmware updates may even improve your phone’s performance as the new system will create new caches that will replace them. Here’s 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.

If the error is still showing up after wiping the cache partition, then the next step might help.

Step 5: Backup your data and files and do the Master Reset

This, of course, will bring your phone back to its factory default settings. For problems like this, a reset is very effective. However, it always has to be the last procedure you should do after trying the first four procedures because of the hassle in backing up your data as well as restoring them after. In your case, it seems like you are left with no other choice but to do this. Here’s how…

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.

That’s all you have to do in order to fix this problem or get rid of this error message.
