Galaxy A90 won’t send MMS fix #3: Force close messaging app

Sometimes, app problems may occur if a system or app has been left running for a long time. It’s recommended that you close all running apps from time to time to lessen the chances of bugs from developing. To see if your Galaxy A90 MMS issue is caused by a minor bug, you can force quit the app. Here’s how:

  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the Instagram app. It should be here if you managed to run it previously. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.

Another way to force close an app is this:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the messaging app.
  6. Tap Force Stop.

Galaxy A90 won’t send MMS fix #4: Delete old conversations

Both incoming and outgoing MMS or texts use the same inbox in your messaging app. If the inbox is full, you won’t be able to send or receive texts or MMS. If you text a lot everyday, it’s possible that the inbox may have run out of space. Try to delete some old messages, especially those that contain a lot of attachments to see if this fixes the problem.

To delete a message in Samsung Messages app:

  1. Open Samsung Messages.
  2. Tap the message you want to delete.
  3. Tap More settings at the upper right (three dots).
  4. Tap Delete message.
  5. If presented with options to select which conversations to delete, tap All at the upper left.
  6. Then, tap the Delete icon at the bottom.
  7. Tap Delete to confirm.

Galaxy A90 won’t send MMS fix #5: Reset network settings

Apps that require internet connection to work may sometimes become buggy if the device has incorrect network configuration. Try to reset the network settings and see if this works:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset > Reset network settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

Galaxy A90 won’t send MMS fix #6: Perform soft reset

Sometimes, bugs may develop if a device is left running for a long time. To refresh the system and get rid of temporary bugs, try to simulate the effects of a “battery pull” procedure and see how it goes. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your A90 using this method at least once a week to lessen the chances of bugs.

For some Galaxy A90, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Galaxy A90 won’t send MMS fix #7: Clear messaging app cache

At times, an app’s cache may affect performance and cause problems. To ensure that the cache of the messaging app is in top shape, try clearing it and see what happens.

  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the appropriate app.
  6. Tap Storage.
  7. Tap Clear cache button.
  8. Restart the device and check for the problem.

Galaxy A90 won’t send MMS fix #8: Clear app data

A follow up to the previous step is clearing an app’s data. If nothing happens after clearing the temporary cache of the messaging app, make sure to follow it up by clearing its data.

  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Samsung Pay app.
  6. Tap Storage.
  7. Tap Clear data button.
  8. Restart the device and check for the problem.

If you’re using a third party messaging app, we suggest that you try to reinstall it instead. Below are the steps to delete or uninstall an app

  1. From a Home screen, swipe up or down from the center of the display to access the apps screen.
  2. Open Settings app.
  3. Tap Apps.
  4. Ensure All is selected (upper-left).  If necessary, tap the Dropdown icon (upper-left) then select All.

In some cases, new updates may cause problems instead of fixing them. Try to uninstall the latest update for an app to see if it helps. Here’s how:

  1. From a Home screen, swipe up or down from the center of the display to access the apps screen.
  2. Open Settings app.
  3. Tap Apps.
  4. Ensure All is selected (upper-left).  If necessary, tap the Dropdown icon (upper-left) then select All.

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile Networks.
  4. Tap Access Point Names.
  5. Select the correct APN.
  6. Configure values as necessary.

Make sure to get the correct APN from your carrier ahead of time.

Galaxy A90 won’t send MMS fix #10: Refresh system cache

If your Galaxy A90 stopped sending MMS after updating Android, it’s possible that there may be a problem with the system cache. This is a set of temporary files used by Android to load apps quickly. If this cache gets corrupted or outdated, a device may suddenly lag, freeze, or show signs of slow performance. At other times, uncommon glitches may occur as well as overall performance of the system may also be affected. To ensure that your A90 has good system cache, we suggest that you clear it once every few months. Here’s how to do it:

  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 cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Galaxy A90 won’t send MMS fix #11: Send MMS on Safe Mode

If MMS on your Galaxy A90 won’t send after an app has been installed, you may have a third party app problem. To check, restart the device to safe mode. Safe mode won’t allow third party apps to run and only preinstalled (those that originally came with the software) can work. So, if your issue won’t happen on safe mode, that’s clear indication of a bad app in the system. To boot the device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.
  6. Try sending MMS and check for the problem.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your A90 is still problematic, repeat steps 1-4.

Galaxy A90 won’t send MMS fix #12: Factory reset

Should none of the solutions above has worked so far, consider wiping the phone with factory reset. Factory reset will wipe the software and bring all setting to their working, factory state. If the reason for the issue is software in nature, factory reset might help. Below are the two ways to factory reset your A90 :

Method 1: How to hard reset on Samsung Galaxy A90 via Settings Menu

This is the easiest way to wipe your Galaxy A90 . All you have to do is to go under Settings menu and follow the steps below. We recommend this method if you have no trouble going under Settings.

Method 2: How to hard reset on Samsung Galaxy A90 using hardware buttons

If your case is that the phone is not booting up, or it boots but Settings menu is inaccessible, this method can be helpful. First, you need to boot the device to Recovery Mode. Once you successfully access Recovery, that’s the time that you begin proper master reset procedure. It may take some tries for you before you can access Recovery so be patient and simply try again.

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up button and the Bixby button at the same time.
  5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
