Update y'all... It's true according to an article I found on Google, Life's Good(LG)really is leaving the phone business. That's why everyone with their brand phone is getting an error message every few seconds. I went to my Boost Mobile store, and he printed me a sheet with directions for a fix. It did not work. Same exact steps that everyone online Facebook Messenger has suggested me thru.

Another thing LG is getting out of the cell phone business so it might be a good idea to get a different brand such as Motorola, Samsung, Apple etc...
Y'all I have excellent news! I called up my service provider Boost Mobile. Other customers have called the issue in. I'm not the only one. When I asked him "Is other customers having trouble with their phones?" He guessed my problem. I didn't even have to tell him. He said "Is it LG LMS keeps stopping?" I said "Yeah that's the problem." He said "Lots of customers have called that in. Bring it in my store I can fix it."
