for about two weeks now I've had terrible service with verizon. dropped calls, static filled calls, beeps and buzzing during calls. I've had limited data during this time as well. phone keeps connecting and then dropping data over and over to the point it's significantly killing the battery. spent the last day and a half only getting a 3G signal. Normally I have full LTE. Something is definitely going on but can't figure out if it is my handset or something else? thoughts?
