[Fix out]T-Mobile/Sprint Samsung Galaxy S20, S10, Note 10 & Note 9 Internal Error (407) permanent bugfix in the works, official workaround inside

New updates are being added at the bottom of this story…….

Original story (published on July 16, 2020) follows:

Samsung’s mobile software has evolved a lot over the years. With the introduction of One UI, many tech enthusiasts agree that it’s easily one of the best Android skins if not the best. Unfortunately, no matter how good the software is, bugs and issues often pop-up out of the blue.

Although if a bug is found, Samsung often fixes it as soon as possible. Recently, we covered the display resolution issues after installing One UI 2.1. And now it seems the company has another issue to deal with.

Certain Samsung Galaxy smartphones appear to have a bug which results in an Internal Error (407) message appearing after every hour. The Galaxy S20 series, S10 series, Note 10 series, and Note 9 are known to be affected.

In order to address the problem, Sprint, now part T-Mobile, released a statement regarding the problem with a temporary workaround. Here’s the official statement from the carrier:

Some users with Unlocked International and Domestic devices are reporting their handsets repeatedly show update errors. Behaviors may involve:

  • OMADM-The profile update could not be completed
  • Error-The profile update could not be completed. Please try again later. If the problem persists, you may need to contact Customer Service. Error: Internal Error (407)

  • In case you are noticing a similar problem on your Samsung smartphone, then you can try the official workaround. Keep in mind that these steps are not a permanent fix. Therefore, you may experience the error once again. In that case, you will have to repeat the process.

    Temporary solution by Sprint

    These error notices do not impact functionality; Voice and Data should still work. However, the errors are a nuisance and repeat hourly. If all other triage has not resolved the behavior, then advise impacted users of 3 temporary workarounds below. Samsung, T-Mobile, and Sprint are actively working on a permanent fix.

    1. Remove SIM from the SIM tray and re-insert SIM. 407 error message disappears in the notification bar. If reboot the device, the message re-appears.
    2. Go to Settings > Apps > System Apps > OMADM > Force Stop. 407 error message disappears in the notification bar. If reboot the device, the message re-appears.
    3. Go to Settings > Apps > System Apps > OMADM > Storage > Clear Data. 407 error message disappears in the notification bar. If reboot the device, the message re-appears.

    Fortunately, you will not have to resort to using the temporary workaround for long. As mentioned in the temporary solution, Samsung and T-Mobile/Sprint are working on a permanent fix for the Internal Error (407) message on affected Samsung Galaxy units. However, there is no ETA mentioned. Hence, we will have to wait and see how long it takes for the fix to roll out.

    Samsung is also working on releasing Android 10 to eligible phones. You can check out our Samsung Android 10 update tracker to know when it arrives on your device.

    Update 1 (October 06)

    It seems that this problem was addressed by Sprint for Galaxy Note 9 users via an OTA update bearing build number ETG2. At present, it’s unclear whether either carrier fixed the issue for other affected devices.
