Galaxy S7 gets SMS fail message after sending, SMS are received in incorrect order, other issues

Hello Android community! Some #GalaxyS7 users have reported a weird texting problem — that they receive message sending failed error when sending text even though the messages were actually sent. At this time, we are not sure if this is an issue with one specific Android version, or it’s a coding issue with carrier-branded firmware. We’ll update this post once we’ll get a definitive solution for it.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 keeps showing error after sending SMS

After a recent software update, I can send text messages and I’ll show that it’s sending and after a couple minutes I’ll receive a text message saying error code add vcnt error code but the text will actually go to whoever I send it to. it only does it but I can send picture fine. I have tried several techniques on rebooting and calling technicians and they’re stating that the problem will fix itself eventually.  Verizon. — Clifford

Solution: Hi Clifford. Try wiping the cache and data of your messaging app to see if it’s being caused by an unknown bug in the said app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to Apps. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, find the messaging app you’re using and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more.
  5. These are all clickable items. You’ll want to click on Storage.
  6. Try clearing the cache first.  If the problem stays, do the steps 1-5 then tap Clear Data.

Clear Data will erase your messages. If you want to save some messages, be sure to back them up first using Samsung Smart Switch.

If the problem remains after wiping the messaging app’s cache and data, consider using another app. The current may have some coding issues after an update.

You can also try to wipe the phone via factory reset to ensure that there’s no existing operating system glitch causing it. 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.
  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 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 messaging app you’re having a problem with is from your carrier, make sure that you report the trouble to them so they can do something about it.

Problem 2: Galaxy S7 messaging app no notifications when conversation thread is open

Hi. I just upgraded from the Samsung S5 to S7 & both phones unfortunately have the same problem (I was hoping the upgrade would have fixed it). The problem is when I am in a text message conversation with someone & I leave the message page open, I do not get a notification if they have messaged me back. In order to get a notification I have to always back out of the text conversation & back into my main text message page (where I go to find a person I want to text). Any suggestions on how I can fix this? — Bex

Solution: Hi Bex. This is NOT a bug or issue. We also observe this behavior in our own S7 and in other older Galaxy S models. When receiving incoming message, the status bar will briefly show a new message notification icon on top but no notification sound or vibration will occur as long as you are actively browsing the current conversation thread. This is how it’s designed. There’s no fix for it.

If you don’t like this messaging app behavior, consider using other third party apps.

Problem 3: Galaxy S7 gets SMS fail message after sending

Performed auto update this past weekend and now every text message I send gets a fail message. I’m getting responses to text messages so I know folks are getting them, but if I don’t hear back from someone, then I’m just not sure. I tried the soft reset. No go. I’ve restarted, powered down & restarted, cleared my cache, etc. Nothing has worked. PLEASE FIX THIS! — Kim.mcgowen

Solution: Hi Kim. Your issue looks similar to Clifford’s above so kindly follow our suggestions for him.

If you are positive that this issue started after a software update, you can also try wiping the cache partition first before doing erasing the messaging app’s cache and data and factory reset. To do that, 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.
  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 doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 4: Galaxy S7 saying failure to send SMS

Since the last software update my text messages are saying failure to send every time I send a text message. But the people I’m sending the text message to are still receiving my text message. But if I send a picture message with a text along with it it does not say failure to send. I have a Galaxy S7 I did put my phone in Safe Mode and the problem is still occurring. I completely rebooted the phone and the problem is still occurring. I deleted all the cache in the app also.        — Jackie

Solution: Hi Jackie. As this is the third case in this post that shows similar symptoms, it’s possible that this is not a carrier-specific problem but rather a bug in a specific to an Android version. If our suggestions above won’t help you fix the problem, the only thing that you can do is to wait until Google or Samsung figure this out. We will continue to monitor this issue as well. If there’s a known working solution to it, we’ll definitely publish them right away.

Problem 5: Galaxy S7 SMS are received in incorrect order

Hi there. I no longer receive my text message in chronological order. Same with my recent calls. Same with pictures I take in my album. I do play with dates for some games I play online but always put it back in the current date after I’m done playing. How can I fix my chronological issues? Thanks. — Nat

Solution: Hi Nat. The only known solution for your issue is by changing the system Date and time to the correct one. If you’ve already did that, it’s possible that those stuff that don’t follow the normal chronological order were created when your phone was set to incorrect date and time. In other words, the time stamp for those files were already incorrect in the first place. Naturally, once you set the correct date and time again, those files with incorrect time and date stamps will be ordered well behind or forward, causing the mess you’re in right now. You can’t undo the given date and time of a file as they are system generated so you either have to take it or leave it.

Two things:

  1. Avoid creating files (like photos, videos), or receiving SMS when the phone does not have the correct date and time.
  2. Avoid changing date and time at all.

If you can’t do any of them or both, then just live with how your stuff are ordered.
