Problem 1: Galaxy S7 edge messaging app “Send” button not working

Hi. I have a Samsung Galaxy S7 EDGE and I frequently am unable to hit the “send” button after i have typed a text message. The button is on the screen but when i touch it, it is completely unresponsive. If i minimize the keyboard the button works and is only unresponsive when the keyboard is displayed on the screen. If i reset the phone it works again for a few hours and then doesn’t work again. I have done a full reboot and wiped the cache but it hasn’t permanently solved the issue. I do not have any new apps or anything that i can think of that would be causing the issue. — Dan

Solution: Hi Dan. An issue like this can be caused by a bug in the messaging/keyboard app or in the operating system. We don’t know what type of cache you cleared but we recommend that you start your troubleshooting by wiping the cache of the messaging app or the keyboard. Here’s how to do that:

  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, click on an application.
  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. You should now clearly see the Clear Cache and Clear Data buttons for the application. Remember, try doing the Clear Cache option first (for both the messaging app and the keyboard app). The keyboard app can be the default Samsung keyboard or something else. If Clear Cache won’t work, try the Clear Data option.

If your problem remains after wiping the cache and data of both apps, consider returning all software settings back to their defaults. Here’s how:

  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.

Bear in mind that factory reset will delete everything including photos, videos, contacts, etc. Make sure that you back them up before doing it.

Problem 2: AT&T Galaxy S7 edge won’t show SMS has been sent after an update

I currently have 2 S7 edge phones through AT&T. Today, one of them started having an issue with one contact only. I send a text from the regular app and then it doesn’t show that I sent a message at all but the person on the other end is getting the message. Am I missing something or is this a glitch in the update? — Tabithadye94

Solution: Hi Tabithadye94. There’s no easy way to know what might be causing this problem but if the only different thing you did before this issue started was to install an update, then that update might have changed things around resulting to what you’re experiencing. If what you mean by update is an app update, try to remove the updated app and see if that will work. However, if what you meant was an Android update, you must do the basic troubleshooting steps for post-update issues namely cache partition wipe and factory reset. Both of these procedures can be done after booting the phone to Recovery Mode, so please do the following:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo 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. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 3: Galaxy S7 can’t send and receive SMS occasionally

Living in NZ for another year. My wife & I replaced iPhones which had no problems with two new S7 purchased in USA. Can occasionally send and receive texts, usually cannot. VERY ANNOYING. Problem worsening to an an every other day issue on both S7 phones. Have downloaded latest updates. Told by tech help this is a common problem with S7. 🙁 Is there a fix that lasts longer than 2 days? Thank you. — MICHAEL P GIROUARD MD

Solution: Hi Michael. We don’t know where that tech support got his/her data about the issue being common in Galaxy S7 devices but we’re in this troubleshooting business for years now and we can say with certainty that it’s not. If you were talking to your carrier’s technical support team, he or she may be deflecting the blame to Samsung to cover issues on their network. The fact is, intermittent SMS and MMS issues are most likely network-related. A phone can either send or receive SMS/MMS or not. There’s no in-between. There may be service interruptions in your area so you  should work with them to identify the problem. Start by minding the signal bars in the affected phones. If both devices regularly receive up to two bars only most of the time, you really can’t expect good texting or voice calling service.

Another possible reason for your trouble is compatibility issue. Your phones are from the United States, which means that their software are optimized to work with a particular carrier in that country. This also means that they’re coded to work with one particular network, which may be different with your New Zealand network. Any change in values or signals may cause changes in your phone’s system in handling SMS traffic, resulting to occasional hiccups. Keep in mind that every carrier, even if they are using the same GSM technology, can cause incompatibility problems that can lead to your situation right now. If this is the case, you’re out of luck. Both Samsung and your carrier can’t help you.

If you want an uninterrupted service, you can sell the phones and get Galaxy S7 devices from your carrier in New Zealand. That way, you’ll know that the software running in the devices are designed to work properly with your New Zealand carrier.

Problem 4: Galaxy S7 not receiving SMS from iPhone users

Hi. I hope you can help. I have a brand new phone and some text messages are not arriving. I think it’s iPhones that I’ve noticed it with. I’ve tried to have them send it regularly, i.e. not iMessage and it still doesn’t come through. Messages sent to myself come through immediately. Thanks so much! — Nathan3814

Solution: Hi Nathan3814. These are the two common reasons why some people may not receive SMS from iPhone users:

  1. SMS are being sent as iMessage
  2. recipient was previously an iOS user and did not deactivate iMessage prior to switching to Android (while using the same number)

If you’re positive that your contacts are not sending you iMessage, then the second item might be true. Make sure that you deactivate or deregister iMessage properly. To do that, visit this page.

If you were:

  • never an iOS user,
  • never switched from iOS to Android
  • never used the same number when switching from iOS to Android

then there must other reasons behind your problem.

Below are the steps that you can do to check for other possible reasons for the problem:

Delete old conversation threads. If you text a lot, chances are your messaging app’s storage has become full. Make sure to erase old messages including the ones from the contacts you’re having problems with.

Ensure that you don’t block some contacts. There are two types of blocking mechanism in your phone. One is a voice calling block and the other is SMS/MMS blocking. Blocking a contact from contacting you via voice calling won’t block their SMS and vice versa. Make sure that the contacts you’re not getting texts from and not blocked in your messaging app. We assume you’re using the native messaging app so here are the steps to check:

  1. Open the messaging app.
  2. Tap More options in the upper right hand side (three-dot icon).
  3. Tap Settings.
  4. Tap Block messages.
  5. Check Block numbers, Block phrases, and Blocked messages.

Clear messaging app’s cache and data. If there are no blocks in place, the next logical step is to clear the messaging app’s cache and data. Refer to the steps above.

Do a factory reset (optional). At this point, we doubt it’s an issue with your device at all but if nothing works, you might as well make sure that you cover all bases by wiping the phone clean. After a factory reset and while there are no third party apps installed, you can check if the problem still happens.

Otherwise, just contact your carrier and ask for direct assistance.

  1. To the user with problem number 2:

    There is, in recent days (the last three to four days, to be exact) something that happened with with a software updates on the S7 models. We have two in our house. We send an SMS and it will sit there and spin and then come back and say it was not delivered or “not sent” when, in reality, it actually has been sent and received on the other end. Many of us have been trying to get Samsung to fix it, or at least acknowledge it but thus far they’ve done neither. It’s across multiple carriers at this point, so it might be worth looking at these threads to see if this is what happening to you, as well.

    (I’ve shortened these with Tiny URL but the first goes to a forum entry and the second goes to a entry.

    Best of Luck
