Lets say you and I are standing beside each other, your phone shows 4 bars mine shows 3, we can both text and make calls. You and I both have the same phone, mine shows 3 bars and yours shows 4. If they work, what is the big deal. Is it system degradation or is it just two different phones showing different signal strengths. My Jeep Grand Cherokee might get a fraction more or less mileage per gallon than someone else with an identical Jeep Grand Cherokee. As long as they both run, it's moot.Seems like im pulling up a lot less bars than before..and a lot of no bars available...maybe its just me?
