Problem #1: How to fix Galaxy A7 texting issue: can’t send SMS

Phone will no longer send text messages. I restarted the phone, updated the phone, cleared out some room in the storage, but nothing has worked. I have excellent service where I am and I have had this problem before but it never lasts as long as this time has. I have unlimited data as well. I was hoping I could figure this out without going into a store if possible.

Solution: Unless there’s a problem with your account or with your carrier’s network, the most likely reason can be found within the device. If this is a device issue, it must be something that you did knowingly or unintentionally. Did you try changing some settings before the issue started? Did you install anything? Was there are any different thing that you did at all? Only you can answer these questions so whatever the answer is, we assume you are wise enough to undo what you did.

If you did not do anything at all and the issue started out of the blue, follow these troubleshooting steps to fix it:

Delete old messages

Any messaging app can only keep a finite number of messages. It’s possible that it may have run out of storage space at this time. Be sure to erase some of your old messages or conversation threads to allow new ones (both incoming and outgoing) to be stored properly.

Check the Message Center Number

Another common reason why text messages fail to send is incorrect Message Center Number or MCN. MCN don’t change by itself so either there’s another app or software bug that modified it, or you may have changed it yourself. To check if it’s the correct one, follow these steps:

  1. Get the correct MCN from your carrier or online. Make sure you have the correct one. Even one incorrect digit can cause a problem.
  2. Open Samsung Messages app.
  3. Tap More settings icon at the upper right.
  4. Tap Settings.
  5. Tap More settings.
  6. Tap Text messages.
  7. Tap Message center.
  8. Edit the Message Center Number.

Reinsert SIM card

Some users were able to fix texting problems before by simply disconnecting the SIM card. If you haven’t tried it yet, be sure to do so.

Use another SIM card

If you have another compatible SIM card from another carrier, using to check if you have a device problem can be a good idea. This should help you narrow down the possibility if your device has lost its ability to send a text message or not.

Insert your SIM card to another device

If you suspect that the problem may lie on your account and not the device itself, try using your SIM card in another device. Make sure that the second device is network unlocked and can work with your SIM or network.

Use another text messaging app

If nothing has worked at this point, it can also be a good idea to try another text messaging app. If you don’t have a secondary text messaging app installed,open Play Store and install Google’s

Android Messages app for this purpose. The aim is to check whether or not the problem is related to the current messaging app so you can use any other app if you don’t like Google’s app.

Reset network settings

Resetting your phone’s network settings is the less drastic software tweak that you must do before doing a factory reset. Here’s how it’s done:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your device and check for the problem.

Factory reset

Wiping the phone and returning its software settings to defaults can be a necessary troubleshooting if all the steps above won’t help at all. Do this before calling your carrier.

Factory reset will erase your personal data. Be sure to back them up ahead of time.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Contact your network operator

The most that you can do as far as device troubleshooting is concerned is factory reset. If the issue remains after wiping the phone, the problem must be on the network or account side. You need to get hold of your network operator to fix the trouble.

Problem #2: How to fix a Galaxy A7 that won’t charge or turn on

Hi. I have the Galaxy A7 duos and can’t get it to do anything at all now. Had a message the other day which said app was closing , overheating etc, then it wiped my home screen photo off, can’t get it back. Since then phone won’t charge, start up — dead. The battery has always been fine before and never had any issues with it charging etc, but since that app closure it’s completely had it. Tried all the start up options you’ve already suggested to no avail. Nothing wrong with plug, wall socket, charger etc. I did manage to start a reboot but I don’t think it got round to finishing it off before phone lost all power and won’t charge . Is my only other option tech guys and is it worth the cost or better new phone. Thanks in advance.

Solution: Given the fact that you’ve already tried all that you can do in this situation, yes, the only option for you is repair. Any of these things can be the reason for the problem:

  • broken charging port
  • bad battery
  • screen issue
  • other hardware malfunction

In order to know the cause, a professional needs to examine the hardware. Unless you are a trained Samsung technician, knowing the cause of the problem is really beyond you at this time. If you’re lucky and the issue is caused by a bad battery only, replacing it can be an easy fix. Other than that, you’ll most likely end up getting a new phone rather than having the logic board replaced.

Problem #3: Galaxy A7 won’t read music from SD card

Ever since I got my samsung A7 I’ve had problems with it reading the music i put on my SD card. Initially it wasn’t reading all the files and was making glitching sounds. I’ve since upgraded SD cards and I’m still having issues with the phone not reading all the files. On top of that when I’m streaming through bluetooth in my truck every once in awhile the track skips and I’m starting to lose my mind trying to fix this issue. Any advice would be helpful thanks.

Solution: Sometimes, devices may encounter errors when reading SD cards used in another device. Be sure to format the SD card using the same device to minimize issues.

The second issue regarding some tracks being skipped may be related to the same SD card issue. We suggest that you reformat the SD card using your Galaxy A7 before adding files to it. This of course is only one of the solutions you can try. The real bug may lie somewhere else. We suggest that you try other basic software troubleshooting like clearing the cache partition or factory reset if that won’t help.

In some cases, streaming music from a phone to another Bluetooth device can be caused by signal interference. Try contacting us again should the suggestions above won’t help. Make sure to tell us the troubleshooting steps you’ve tried so we can easily consider other possible factors.
