Samsung Galaxy A20 MMS won’t send. Here’s the fix.

We have received quite a lot of complaints from our readers that own the Samsung Galaxy A20 saying that MMS won’t send on their phones. While a picture message is basically a text message with attachment, it needs to be transmitted via mobile data due to the size of the file. Needless to say, your phone must have an enabled mobile data connection. When troubleshooting a problem like this, you need to determine if it’s just because such service is disabled. 

But in this post, we will try to look into more possibilities and then rule them out one after another until we can determine what the problem really is and hopefully be able to fix them. If you’re one of the owners of this phone and are currently having similar problem, then continue reading as we may be able to help you. 

Before anything else, if you have other issues with your device, try to browse through our troubleshooting page as we’ve already addressed several issues with this device.

What to do if MMS won’t send from Galaxy A20

There are a few settings you have to check on your phone to make sure everything is in order but after checking those and your Galaxy A20 still can’t send MMS, then your service provider may have an answer for you. After all, MMS transmission depends on on your phone’s connection to your provider’s network. But here’s what I suggest you do about it…

First solution: Reboot your phone

This is only for devices that were able to send MMS but at some point stopped. A reboot is necessary as it might be a minor issue with the firmware or a glitch in the system. So, hit that power key and reboot your device and if the problem is still not fixed after this, try doing the forced reboot: 

  • Press and hold the volume down and power keys at the same time for 10 seconds or until the phone restarts. 

This method simulates battery disconnect and refreshes  your phone’s memory. It might be the only thing you need to do to fix this problem. So once the phone becomes active after the reboot, try sending an MMS to your own number to know if the problem is fixed. If still no, proceed to the next solution.

Second solution: Toggle mobile data off and on again

If you’ve been sending and receiving MMS for a long time already, then you already know that mobile data is required in order to transmit these kinds of messages. There are times when a glitch occurs in some core functions and in this case, it might be the mobile data function that’s affected. So, go into the Settings menu and then turn mobile data off for a few seconds and turn it back on.

After which, try composing and send an MMS to your own number to know if it goes through and if you can actually receive it. But if MMS won’t send after this, try the next step.

Third solution: Reset Messages app

Another possibility we have to rule out is the fact that maybe the problem is with the messaging app you’re using. In the case of the Galaxy A20, the default messaging app is called Messages so  you need to clear the cache and data of this app and then try sending an MMS again.

  1. From the Home screen, touch and swipe up or down to display all apps.
  2. From the Home screen, navigate: Settings > Apps
  3. Tap App Manager.
  4. Locate then tap Messages.
  5. Tap Storage.
  6. Tap CLEAR CACHE.
  7. Tap Cached data.
  8. Tap CLEAR.

After doing this, try to see if the problem is still happening and if it still does, I suggest that you do the reset.

Fourth solution: Backup your files and data and reset your phone

This is to eliminate all other possibilities because there are times when a firmware glitch causes issues like this. Before you reset your phone, make sure you backup your files and data as they will be deleted. After which, make sure you disable the Factory Reset Protection so that you won’t be locked out after the reset. Follow these steps…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Cloud and accounts.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap on your Google ID email address if multiple accounts are setup. If you have multiple accounts setup, you will need to repeat these steps for each account.
  6. Tap 3 dot icon.
  7. Tap Remove account.
  8. Tap REMOVE ACCOUNT.

Now follow these steps to reset your phone:

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy A20 logo shows, release all three keys.
  4. Your Galaxy A20 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

After the reset and the problem continues, call your service provider. If the representative cannot help you on the phone, bring the phone back to the store. It’s ready now since you’ve already wiped off all your personal files and data.
