Hope you don't mind the "dumb" questions--I'm still too new to ask really good questions.
I have two Nexus 5 phones. Some weeks ago, I wanted a Nexus 5, but I was on Verizon. Naturally (I think!), I switched to T-Mobile after receiving my new Nexus. Then the trouble started.
After numerous attempts, I called T-Mobile tech to ask why I could not connect to the service. They decided my phone was defective and sent me a replacement.
Trouble continued. The new phone would not connect either. I happened to move to different location in my house, and suddenly I could connect!! I tried the "broken" phone in this same "new" location, and it connected, too!!
Too many similar problems to detail here. The "no connection" problem had to do with "no T-Mobile signal" at my house, ever though I was technically in their service area.
Within 14 days, I went back to Verizon (with an "old" flip-phone). I kept my two WORKING Nexus 5, hoping Verizon and Goggle might get together one day, and my phones would work on Verizon.
My first Nexus 5--the one T-Mobile determined as defective--upgraded to Lollipop a couple of days ago. The second Nexus 5 still shows 4.4.4 and responds with "phone is up to date."
Anyone have a suggestion as to why one phone received the OTA Lollipop and the other continues to refuse it?
Thank you.
