Why has my LG G3 stopped sending texts to multiple people in a group?

[AC Question]

Just recently, when I program in more than one person to send a text to, my LG G3 gives me a long send message, then a 'not sent, try again' message, but until I delete the group, it won't send other texts either.

Hi there!

If you downloaded any 3rd party texting apps, that might be why. If so, uninstall them and see if the problem exists with the native text app. If you didn't install any 3rd party. Try these things:

1. Enter Safe Mode and see if that helps.
2. Open text app, goto "More" goto "Settings" goto "More Settings" goto Multimedia messages. Make sure Group is on. if on, turn off then back on.
3. Goto Settings > Application Manager > Scroll Over to ALL > Scroll down to "Messages" then Clear cache.
4. Register for our forums so we can assist you further.
