Just recently I've had a new issue (2 times) with my Verizon S4. Both times happened when at/leaving work. At times I have no service at work....then when I go outside or move to another area inside where there is service I get no sound when making a call either to another phone or voicemail. It'll show that the call connected with timer counting up but I hear nothing....then after a little bit the call disconnects by itself. While it was acting up I tried calling my cell from a landline & it would ring....I answer it & hear nothing on my cell and on the landline I hear no voice coming from my cell. Then if I restart the device everything works fine. Today when it happened I tried turning on airplane mode then turning it off....didn't help. I had to do another restart then ur worked fine. Anyone else experience this lately?
