Problem #1: Galaxy S7 unable to read encrypted SD card after Marshmallow update

Hey you guys seem fairly knowledgeable so here it goes. I buy the phone when it drops — no problem. About a week later my brother comes up and he has a Samsung 32 Pro Plus SD card. We do a quick test and it’s faster than my 2-year Sandisk 64 Extreme plus. The test is just dragging a movie file back and forth in Windows. It hits like 100 a. He lets me keep the card.

Sometime later, i encrypt the card — still no problems. Sometimes after that, the first OTA update comes. And that’s when all the problem started. Basically, I’m locked out of the encrypted card. The phone that encrypted has forgotten it encrypted it. In short I’ve tried everything except probably a witch doctor.

I’ve refreshed it, Live Chat with Samsung and they have refreshed it. I brought it to a local Best Buy Samsung kiosk and they basically refresh. With that I’m saying I’ve never seen anything like this. It makes it seem like there is an SD slot issue when in fact the card can’t be accessed because its encrypted.

While reinserting the card does offer to decrypt the card, it doesn’t actually do it. And its stuck in no man’s land. While i use a big secret letter to encrypt and decrypt the card, the underlying hash key must have been lost or spun during the OTA. This has all happened a while back in 6.0 days. l have long since put it back in its adapter and in a drawer waiting for some future technology to come along and decrypt it. I’ve also never seen this mention as being a problem ,and don’t know how many people bother to encrypt their cards. Meanwhile Sandisk is dropping the extreme 256 in a couple of days, and the old S7 is starting to show its age Cat 9 vs Cat 12 USB 2.0 vs USB C and UHS1 vs UHS2  🙂 Any help would be most appreciated. — Zeno

Solution: Hi Zeno. Updating from one Android version to another (like moving from Lollipop to Marshmallow) is not supposed to change how the encryption key is handled. In fact, it’s our first time to encounter this issue so it may be caused by something unique to your phone. This unforeseen variable can be anything — a bad app, an unknown operating system glitch, a rare firmware quirk — anything. Since the issue did happen anyway, the only suggestion we can give is proven and effective factory reset. That if you don’t mind losing whatever files you’ve stored in that SD card anyway. While you’re within your right to wait for a more advanced decryption process that might be made available in the near future, we can’t really say it’s happening in the next few years. As far as our knowledge regarding encryption is concerned, current SD card encryption method being used by Samsung is still state-of-the-art and will not going away soon. That said, there’s really nothing much that you can do on your end at this time. There’s still no new decryption method that will help you unlock that SD card. Even Google and Samsung won’t be able to.

Problem #2:  Galaxy S7 keeps showing SMS is not sent

I have had issues with sending texts messages and it will show up grey with an exclamation point and pop up with a message not sent box with options to delete, resend, or edit text. When I asked my mom and my best friend if the messages I sent to both of them when through they both said yes. So even though it’s saying not sent it’s really being sent.

Also it takes my phone or Rogers about 20 minutes when off the LRT train (mostly underground) for me to get reception back to send a message. I can receive texts while I’m waiting for reception but not sending. I have talked with Samsung and Rogers and they both blame the other person. Plus when the big update was pushed thru on Oct 7 it made my phone so hot it blistered my hand (I have the S7) and phone was not working from before 6 am to 6 pm when I took it into the Samsung store. — Heidi

Solution: Hi Heidi. Hi Heidi. The first thing that you want to do here is wipe the cache partition of your phone. This will force the phone to build a new system cache afterwards. Technically, the system cache helps the system load apps faster but sometimes, a corrupted cache can also affect how they perform. Making sure that the system cache is up-and-running is a must. To do that, please follow these steps:

  • Turn off the device.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • 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).
  • Press the Volume down key several times key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ an press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

After wiping the cache partition, your next troubleshooting is deleting the cache and data of the messaging app you’re using. Here’s how to do it:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, look for the messaging app and tap it.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

After wiping the messaging app’s cache and data, observe how it works for a few days to see the difference. If nothing changes, do a factory reset.

Problem #3: SMS are delayed on Galaxy S7

Just yesterday I started noticing my friend’s messages where coming, but they were delayed — I was receiving them hours after they were being sent. It got worse now; I can longer get messages from anyone. I tried with my mom’s phone which is the same one with the same carrier; hers worked fine but mine didn’t.

I have already deleted messages and turned off my phone for at least 3 hours. I also noticed my bleacher report notifications were also delayed (I was getting scores to games 5 hours after it had already been completed). Youtube notifications most of my app seemed to be delayed. — Ronny

Solution: Hi Ronny. Please follow our suggestions for Heidi above. If nothing works, do a factory reset. Make sure that you create a backup of your important files before doing it. Here’s how to factory reset your S7:

Step 1: Turn off your Samsung Galaxy S7 Edge.

Step 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.

Step 3: When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

Step 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.

Step 5: Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Step 6: Once highlighted, you may press the Power key to select it.

Step 7: Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Step 8: Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

Step 9: The phone will now reboot longer than usual.

Keep in mind, if the issue persists after a factory reset, the SMS delay may be network related. Contact your carrier for assistance.

Problem #4: How to fix “Unfortunately IMS Service has stopped” error on AT&T Galaxy S7

Hello. I’ve been searching your site for my issue. I just got the Samsung S7 Active yesterday. I did the upgrade late last night. I have been having the “unfortunately IMS Service has stopped” message popping up every 30 seconds. It doesn’t matter if I’m on my phone or if it’s sitting. It has been popping up non-stop since the update. I saw a section on here where a person had said it was popping up only when they were in text message. I tried doing all that was suggested but to no avail. The only thing I can think of is taking it back in to the ATT store. But it’s such a hassle especially since I’ve already personalized it. — Damaris

Solution: Hi Damaris. This error is caused by a bug from one of AT&T’s apps following a Marshmallow update. Make sure that you turn off any AT&T cloud service or any app that offers saving to the cloud. To fix it, do these steps:

  • Go to Settings.
  • Tap Applications.
  • Tap Messages.
  • Tap AT&T Messages Backup & Sync.
  • Tap Stop Backup (link).

Problem #5: Enhanced Feature box keeps popping up on Galaxy S7

The Enhanced Feature pop up popped up on my phone. I activated it and went through with it and a notification was sent to me with a specific code. The enhance feature is activated on my Galaxy S7 and one of my capacitive buttons does not work. My quick launch doesn’t too and notifications don’t show anymore . I’d really like to recieve some help with disabling the enhanced feature ASAP, without having to do a factory reset. If there is no other way, if I back my phone up right now and then wipe the phone, restore the data, would I not have the problem Still? Please get back to me . Thank you. — Sibusiso

Solution: Hi Sibusiso. Try checking if this error is caused by Simple Sharing Feature. To do that, follow these steps:

  • Tap Apps from the Home
  • Tap Gallery to continue.
  • Tap on the image you want to send. You may choose any image to share from the Downloads, Camera or More tab.
  • On the image preview screen, tap the Share icon at the bottom.
  • Tap the Contacts icon to proceed.
  • Select the contacts you want to send the image to from the phone’s All contacts To select a contact, just tap on the checkbox next to the contact (recipient).
  • Tap Done to continue.
  • Verify the recipients are correct, and then tap OK to initiate file sharing via Simple sharing. Please note that additional charges may apply when sharing files via the mobile network. To make sure, please contact your service provider and verify if extra charges are applied when sharing files using your mobile network.
  • Wait until the files are completely uploaded and successfully shared.

If that won’t change anything, try toggling Enhance messaging. here’s how:

  • Go to the Home screen.
  • Touch Apps.
  • Touch Messages.
  • Touch More from the Messages screen.
  • Touch to select Settings from the given options.
  • Touch Enhanced messaging.
  • Touch the ON/OFF switch to turn on (enable) Enhance messaging.

If any or both of these procedures won’t help, you must do a factory reset.

Problem #6: Galaxy S7 fails to power on after charging

Hi. My Samsung Galaxy S7 is less than a month old. It’s been working fine until two nights ago. Overnight, I plugged it in to charge. It does this fancy charge that I don’t need where it only takes 1 hour or less to fully charge the battery (could be part of the problem?). I wake up in the night to check the time and find my phone won’t turn on and has a steady-on green LED indicator. I have to hold the volume and home buttons (which I learned from your site at 2am. sigh) in order to reboot the phone, at which point it works perfectly… Until the following night when I plug it in to charge and the same thing happens. Should I get replacement phone or is there a way to find out what’s causing this? Thank you for your help, Amy

Solution: Hi Amy. Like you, there’s no way for us to know what is the exact cause of your issue. Try doing the basic software troubleshooting first to see if they will help. We suggest that you try booting in safe mode while charging. If this issue is being caused by a third party app, the problem should not happen while safe mode is enabled. To boot in safe mode, follow these steps:

  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Remember to boot in safe mode first before charging the phone. If the same thing happens, wipe the cache partition and/or do a factory reset steps provided above. We think the issue should go away after a factory reset but should it stay, find a way to have it replaced.
