Problem 1: Galaxy S7 Messaging app contacts format is different, contacts format Surname, First Name

When I press to compose a new message, my contacts to select a recipient are sorted and displayed Surname, Name. My contacts are saved with First name first and Surname second on my device. They also display like that (in Contacts settings, I have Sort by ‘First Name’ and Name Format ‘First, Last’). I can’t find a way to display the recipients in this format when I compose messages. — Kostas

Solution: Hi Kostas. The default format for contacts list is determined by your messaging app’s settings or design. Selecting the Surname, First Name format in Contacts app won’t affect how your messaging app’s format looks like. If there’s no setting under you messaging app to change the contacts format, then we suggest that you try other messaging apps that do. As far as the default Samsung Messages app is concerned, there’s no option to change how contacts appears when composing a message. We are positive though that the standard Samsung app uses the First Name, Surname format. If you are using the stock Messages app but it keeps showing the Surname, First name format, consider wiping its cache and data. This will reset all settings of that app to defaults. Clearing your messaging app’s data will erase all messages. Be sure to back important messages up first to prevent losing them. Here’s how it’s done:

  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, look for the application 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. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 2: Galaxy S7 keeps getting sending failed error when sending SMS

On September 22nd I noticed that my Samsung Galaxy S7 texts were not sending. The little spinning circle would just spin and if i rebooted my phone it would automatically say that the message failed.

Now some of my contacts said they still received the message even though it kept “thinking” or failed, but i never got their texts. I didn’t realize this until my husband and mother both asked me why i didn’t respond. My husband has T-mobile as well but he has an Apple phone and is not having this issue, so i know it’s not with the carrier, so going to them will not help.

I spent the next two days looking for a fix and trying different things.


  • Soft Reboot
  • Hard Reboot
  • Taking out battery and SIM
  • Clearing Data
  • Clearing Cache Partition
  • Clearing Message Data
  • Clearing Google Service Firmware
  • Reconnecting to t-mobile network


I found at one point i could take the WIFI off and it would send some of the messages or let me get some of them. But then it would stop working and i would have to go hunting again. I found this page and have tried many of the suggestions listed. I did find that on this last Hard Reboot, that, as i cleared all data and my husband put some Firmware on it from Odin and then did not really set up anything on the start up, that i could text all day today, until the phone started to automatically do system updates.

I did add Netflix and reconnect to the wifi at this point. That’s when the updates started since my phone only does them when there is WIFI around. I was not able to see the list of Updates that happened at the exact moment it failed so i’m not sure which update it was. But what can i do?

If i don’t have my WiFi i can’t stream or download things without a huge bill from my carrier, I also am stuck with a phone that is pretty much useless now as all my contacts are moms and texting is how we’re able to communicate. Please help, this is very frustrating! — Monica

Solution: Hi Monica. You’ve already did everything that an Android user can do to troubleshoot a device so it’s safe to say that this must be carrier- or coding-related problem. By coding problem we mean that the firmware update you installed must be poorly built and causes this bug. If texting works normally after your husband flashed an older Android version to the phone, then that’s a confirmation of our suspicion. We really can’t say for sure where the problem lies but it’s good if you can let your carrier know about it. If there are more users having the same or similar problem to yours, they’ll most likely act on this problem more quickly.

As far as device troubleshooting is concerned, we don’t think there’s anything more that you can try.

Problem 3: Galaxy S7 incoming messages are out of order

I’m a devoted fan of the Samsung line of smartphones and a friend of mine has a text messaging issue that has me perplexed.

She has the Galaxy S7 and about 6-8 months ago, she left Ontario for a trip to Alberta and when she returned home, her phone developed a glitch. Whenever she texts, her message shows up at the bottom of the chat dialog… thats normal, though when the reply comes in it defaults to the top of the chat dialog soo her messages start from the center down and the replies keep putting themselves at the very top. This issue is crazy, i’ve never seen a glitch work out like that before. — Patrick Bernier

Solution: Hi Patrick. This issue can happen if the phone has incorrect system time, date,and timezone. Be sure to tell your friend to change them to the way it they were before by using the network’s provided time.

Problem 4: Galaxy S7 messaging app not working, “Unfortunately SMS Service has stopped” error

I have a Samsung Galaxy S7. After the 7.0.1 update, I started getting the “Unfortunately SMS Service has stopped” pop-up. At first, when I rebooted, then more frequently, now about every 15 seconds. I use Android Messages app. I tried a bunch of suggested fixes… cache clearing, Messages data/cache clearing… soft reset, etc. Some seemed to work, but only temporarily. As of today, I was no longer able to SEND sms messages. I could receive. I chatted with Verizon and he supposedly reset the message center number and outgoing SMS worked… until I hung up. Then it stopped. At least I got SMS working again by switching to the less-preferred Version Message+. but I still get the error pop-up. I would love a solution that did not involve a full reset. — Bill Davis

Solution: Hi Bill. Well, you really don’t have much choice at this juncture. We don’t know what’s the state of your phone’s software so factory reset is the only thing that you can try at this time to ensure that all software settings are returned to defaults. Only then will you know if that will even fix the problem or not. Most app issues are fixed once a full reset is done though so hopefully everything will turn out just fine.

To factory reset your device, 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 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.
