Hello all. I am one of those leeches who show up here whenever they have a question or crisis and then vanish without adding anything positive or useful to general discussion. I have a crisis. Here I am. Feel free to ignore, or help, or help while berating me for being a leech. My Galaxy S3 (Verizon) and my workplace do not get along. I was pretty early with the S3, and began my job in June of 2014. By then, my phone was well-acquainted with that building, as I had been a regular volunteer there since before I got the phone. I was able to do all things phone and smartphone from most places in this steel-with-concrete-floors building at first, but by the time I started my job, things were definitely boggy. Getting on employee rather than public WiFi helped but not much. Long about late July (I think) cell coverage got terrible. I went from a few dead zones to the whole building being a dead zone. Standing in formerly perfect locations now throws my phone into and out of roaming, or I get 'no network' unless I walk all the way outside and stay there to make a call. The IT guy and I have had conversations about this, and he assures me that we have VZ network extenders and that nobody else is having this problem. I hope they aren't. I worked on Christmas Eve. I got there at 10:00 a.m. and turned my phone off at 6:30 p.m. My phone was in my pocket the entire time except for two texts from the boss. Bluetooth was off. Location was off. There were no apps running. I walked in with battery at 94%. I turned the phone off because it was at 17%. This is typical. But it happens only in that building. Nowhere else. Ever. I've done all the troubleshooting I know how to do. I've done troubleshooting I didn't know how to do. The list includes: Phone off and on WiFi off and on Forget WiFi and reacquaint with WiFi Bluetooth and location off New battery (OEM) Another new battery (Anker) Phone reset Take phone out of case Take phone out of pocket Replace phone WiFi antenna Replace phone back housing There was probably more. Nothing has helped. It seems like my phone is killing its battery desperately searching for signal - sometimes text messages don't send, sometimes I miss incoming calls but get the voicemails, sometimes I get the VMs a dozen times as I go in and out of roaming, sometimes I can get texts to send by waving the phone and hopping on one foot. I might be joking about that last. Other people gripe about the bad reception, but nobody has anything like this degree of battery-killing problem. And it's not 'that address' - it's 'that building.' If I'm outdoors, I'm fine. Any ideas? Anything else I should try? I apologize for the long post, but this is nuts. Thanks in advance.
