I have had my s7 for a few weeks and it has the worst cellular reception of any phone I have ever owned in my life.
I have lived in the same place for 17 years and been on the same network for 10 years and have NEVER had a call fail to come through to me and never been unable to make a call - until I got this phone.
The reception where I live is pretty bad - on iphone for instance, I get 1-2 dots downstairs and 3 upstairs.
Noticed a couple of weeks ago that I was getting alerts that I had voicemail. Most of my communication is via whatsapp etc using wifi, hadn't occurred to me to look at the cellular coverage, but when I did, I noticed that half the time, I have no signal at all. If I do get a signal and then pick the phone up, it usually vanishes.
The maximum I can get is 1 bar and even with that, if I call the phone, it goes straight through to VM.
I bought two of these phones at the same time - one to give to my business partner when we meet later this month - so I tried using the second phone - and it is even worse!
In short, have used six different BlackBerries and three different iPhones (plus a cheap credit card size phone) and none of them have ever missed a single call in my house, however, have used two S7s in the same locations and same network and can confirm they are almost unuseable.
Anyone want to buy two nearly new S7s? would suit someone who does not want to be disturbed by people phoning them!
