LG devices on T-Mobile may have experienced a serious hiccup towards the end of the weekend. A backend change caused LG devices to display a persistent error that caused “LG IMS” to crash without ability to connect to cellular services. The following error message above continued to show, even after being dismissed, with little time to perform other actions between error messages.

Unfortunately, LG IMS has stopped.

The good news is that a resolution has been issued. Anyone with an LG device on T-Mobile experiencing this problem should restart their devices to fix the issue. Those who do not restart their devices should see the issue resolved over the next day. This was confirmed by one of TMo Report’s ‘trusted sources’.

The cause of the issue was a change T-Mobile made to its systems that affected the LG devices connected to the carrier. The app that displayed the error, LG IMS, is a system protocol used to handle data and voice connections over LTE. This component of LG’s firmware was briefly broken, causing these devices to become unable to make calls or use their device with the message constantly in the way.
