I bought my S4 about 6 weeks ago and it has been a great phone. This past weekend I was in a rural area where cell service has historically been marginal. Phones have always worked for voice and text but you can forget about decent internet access.
In this environment my S4 had zero internet service, would not send texts, and quickly lost battery charge. All this while my wife's iPhone 4s worked as always, phone and texts fine and marginal internet. I ran by the local Verizon store this morning to compare my dbm reading with other phones and to discuss the problem with the staff. The dbm reading on my S4 was -106, about the same for like or similar phones in the store. The person I was speaking with suggested the difference could be that the iPhone 4 operates on 3g rather than 4g, as did my prior phone.
So the question is, can 4g be switched off on the S4? A quick look at the menus seems to indicate 'no'. If not, is there any other way to make the S4 reception as good or better than the iPhone 4 in this type of environment? As I find myself in less than perfect cell environments quite often, this could become very important some day.
Thanks,
