Wait, so your saying this problem started happening AFTER you did the OTA LG8 Update...or its been happening since you purchased the phone? If its been happening since you purchased the phone, I would strongly advise exchanging it or wreaking hell on earth in a sprint store if they refuse. When you pay $500.00+ for a piece of hardware, there is absolutely no excuse for it not to work for years. I have not experienced this problem with my phone, however, I would strongly advise installing BlazerROM or StrongSteves Blue ROM. It could be that the OTA update you did was a bad flash. Find a stock tar around here, ODIN back to stock, and do the OTA updates again...or install a custom ROM like I advised earlier.
