Hi guys. Feel free to flame me if this is addressed somewhere, I used search and couldn't find anything. My coworker has an LG Vortex. In our shop, we had bad cell service so our boss had a signal repeater put in. Now at&t (all the rest of us are on) works great, full service. This guys LG Vortex on Verizon network shows good service (3-4 bars, I don't have the technical signal strength) and texting and internet work fine, However, for some reason when ever he receives or makes a call it's crackly and usually get dropped. He noticed it to start right after the signal repeater got set up. Any ideas on what to try to fix it, or at least what might be the problem?
