Welcome to the wonderful world of the OE.
Mine always seemed to do that when connected to the network.
I always hated the OE. Held onto for a long time so I didn't lose my grandfather plan.
A few days ago I could not take it anymore. Was not sure I was going to try another LG phone or not. Had the OV first, great phone. Then tried the OE. What a POS! I had to do something and people seem to really like the Optimus F3.
So I bought an Optimus F3.... It's so nice when a phone works the way it's supposed to. LG has redeemed themselves for the junk OE..
Loving this phone, should have done it sooner.
