I have had an issue with my Galaxy S5 not ringing with incoming calls which I posted about in the S5 forums. So today, I finally got a second to go to a Verizon Store. So after waiting my turn for 40 minutes, a Store associate finally got to me. So I relay what I know to date. Phone doesn't consistently ring, slide to answer doesn't always show up, SD card corrupted, SD card was pulled (which never happened). So he looks at my phone for 20 seconds. He shows me the GSam screen that he has opened up. "What is this?" he asks. I tell him what it is. He then says that that must be the culprit and I should delete it. So right away, i know he's an idiot. Then he tells me that because the phone can monitor the battery, it is causing a conflict and not working properly. So just to clarify what he is saying, i ask him how a battery monitoring application, which I have had on 3 different android phones now, caused a phone to not ring? He tells me that is what is causing the issue and I should delete it. So after an admittedly insulting laugh, I tell him thanks for the tip. He ends by telling me I have no other options. He adds because my screen is different ( I have APEX launcher and zedge screens) they can't exchange it. I just look at him weird. So he explains further that due to my screens appearance, it is obvious I have altered the phone from how it was from the factory and they cannot exchange it. So now I'm getting angry. I ask him how an application, available from the play store can violate a warranty? How me customizing my phone, something android, by it's very nature, encourages, prohibits me from having a phone that works. So this genius is representing Verizon. Why??? I will try again after I enhance my calm. Thanks for letting me vent a bit.
