Fix: “Unfortunately, LG IMS has stopped.” on Android

LG IMS error might occur mainly due to issues with the phone’s IMS app or corrupt network settings of your phone. The IMS app issues might range from outdated apps to having corrupt cache or storage. The error is generally reported after an OS update.

LG IMS Error

The error starts popping up randomly (up to 10 to 20 times a minute), making it nearly impossible to use. The error is not carrier or country-specific, but most belonged to T-Mobile or Boost. This error is nearly reported on all types/models of LG smartphones.

An LG phone might show IMS error due to many factors:

  • Outdated LG IMS App or the LG Phone’s OS: If the LG IMS app or the LG phone’s OS is outdated, then one’s incompatibility with the other may lead to a continuous pinging of the phone’s IMS modules which will ultimately fail at a point and may stop working.
  • Corrupt Cache/Storage of the IMS App: Your LG phone might show the IMS error if the cache or storage data of the IMS app are corrupt, and due to this corruption, the IMS crashes after each reinitialization.
  • Corrupt APN or Conflicting Network Settings of the Phone: If the phone’s APN settings are corrupt or the network settings (like using IPv6 as the default protocol) are not configured as per the IMS requirements, then that could also cause IMS to stop. This is because whenever the IMS modules are reinitialized after a crash, the corrupt or conflicting network settings cause another crash, hence a continuous loop of the stopped error.
  • Corrupt OS of the LG Phone: Your LG IMS error might occur if the OS of your LG phone is corrupt, and due to this corruption, the IMS modules of the phone constantly crash as these modules cannot access the resources essential for the IMS operation.

1. Enable and Disable Airplane Mode of the LG Phone

Enabling and disabling the airplane mode of your LG phone may re-establish the phone’s Internet connection, thus solving the problem.

Remember that this error message may frequently be bombarded on your screen and make the troubleshooting process impossible.

If the LG IMS stopped error pops out during the process, ignore it and continue with the above steps.
    Force Stop the IMS App on the LG Phone
  9. Now disable the phone’s Airplane Mode and then check if it is clear of the LG IMS error.
  10. If that did not work, enable Airplane Mode on the phone, and afterwards, enable Wi-Fi (keep Airplane Mode enabled).
  11. Ensure that the Wi-Fi calling is enabled (under Settings>> Call) and repeat steps 2 to 9 to check if the IMS problem is solved.
  12. If not, then put your phone in Airplane Mode and remove the SIM card from the phone.
  13. Repeat steps 2 to 9 to check if that clears the IMS error.
  14. If the issue persists, check if clearing the cache/data of the Messages app clears the LG IMS error.

13. Disable RCS Messaging of the LG Phone

RCS (Rich Communication Services) is the communication protocol mobile carriers use to support their customers in sending pictures and videos with normal text (unlike SMS, where only text can be sent). If the RCS module of your phone or carrier is glitched out, then their continuous attempt to access the IMS modules could cause a stoppage of IMS. In this scenario, disabling the RCS Messaging of the LG phone may clear the error.

  1. Launch your Messaging app and open its Settings.

In this context, changing the phone’s connection mode to IPv4 may resolve the problem. 

  1. Put your phone into Airplane Mode and then open the phone’s dialer.
  2. Now dial the following code to enter your phone’s hidden menu (if this code does not work for you, then search the LG website to find the code to access the hidden menu of your LG phone):
    277634#*#
    Open IMS Settings in the Operator’s Hidden Menu
  3. Then head to IMS Settings (you may find it under Modem Settings). The IMS Settings menu will be where you have the option to enable/disable VoLTE.
  4. Once in the IMS Settings, scroll down till the IP Version setting is shown and then change the setting to IPV4v6 (the default value is IPV6V4).
     
  5. Now close the menu and check if the phone’s IMS error is cleared.
  6. If not, check if changing the IP Version to IPV4 resolves the issue.
  7. If the issue persists, check if repeating the above steps after removing the SIM card from the phone solves the problem.

15. Reset the Phone’s Network Settings and All Settings to Defaults

An LG phone might show the IMS error at hand if your phone’s network or settings are corrupt or not configured as per the IMS requirements. In this context, resetting the phone’s network and all default settings may clarify the issue under discussion of the LG phone issue.
