I live in a 4G LTE area. About a week ago, I stopped being able to make and receive calls from inside my houseon a Droid Mini. I live about a quarter mile from a cell site mounted on a light pole in a strip mall with a authorized Verizon Wireless dealer as one of the tenants. So, I walked to the strip mall along with a borrowed cell phone with service from another carrier. I was able to get a call completion rate of 80% between the two cellphones at the strip mall. Then, I went to other shopping areas about 5 miles from home. In some areas, I got good results. In others, I again could make or receive calls on the Verizon phone. I went through all of the troubleshooting steps here on the Support area of the website, including the factory reset. Nothing helped.
I wanted to buy another small smart phone the size of the Droid Mini, but Verizon has none at present. I lost two other phones because they worked their way out of my pockets. I also had trouble getting them out of my pockets in time. So, I decided to buy a used Droid Mini on ebay claiming to have been used for only a short period. I got it yesterday, and it looked in mint condition. Assembled about a month earlier in 2015 than my own phone. Got it swung over and activated on the Verizon, and still could not make or receive calls from my house. The representative transferred me to a tech, who checked everything he could, and said everything checked out fine. So, I walked back down the the strip mall, and started to get service again at about the same spot as I did on my own phone a week ago.
I am thinking of buying yet another used Droid Mini, but I wonder what the chances are of two phones with exactly the same problem. My landlord (also on Verizon) has not experienced any problems on his floor. Nor do I have any problems with the borrowed phone, potentially eliminating a interferrence or jamming issue.
Text and Internet seem to work sporardically from the house. I would send a batch of test text messages from the Droid Mini to the borrowed phone. Somewould go through right away, while others would stay stuck on "sending" for several minutes, arriving a long times after most messages were received on the borrowed phone.
Any other suggestions besides two bad Droid Minis?
