LG G3 started to get random duplicate texts, sometimes they are days old and randomly show up as a new text. It all seems to be random, it started about a week or so ago, but is a pain. Please tell me how to make it stop!
Back up any text message threads you want to save.
Then go to settings>application manager>all (scroll left to all) and find your messaging app
clear cache, clear data and restart your device
