Bought my S6 middle of May. Having two major issues. First, at my home, I'm surrounded by 4G towers, yet my signal constantly jumps from 4G 1 bar, to 3G 1 bar, to 1X full bars. This is continual, indoors and out, some hours of the day are worse than others. Multiple calls to Verizon and trouble tickets opened, no solutions yet, any thoughts? 2nd problem, just popped up today, when making a phone call, I cannot access data activity. My dad called and asked me to search out something for him, since I was on my headset I tried to search, phone was in 1x, as soon as a I hung up, phone went into 4G mode. 40 minutes on the phone with Verizon, no resolution. Thoughts?
