Four bars me hole!
I'm not sure about you, but I'm sick of my iPhone telling me that it has two fulls bars but still won't connect to a call. Or even worse, when it displays four bars but sounds like I'm calling someone through a plastic sack, in long corridor, with a high ceiling, while driving through a tunnel, at the top of a mountain, in space.
I'm not saying that scenario is likely, but I'm giving you a view into a day in the life of my horrible phone signal. Thankfully Tech Insider has made a video that's given us a handy trick to knowing your actual reception is, so even though you still won't be able to make a call, you'll at least now know to give up and admit defeat.
