Why did the phone stop getting a signal?
Recently my phone stopped getting a signal. Having no memory of dropping it, bumping into something with the phone in pocket, or placing it near any liquids, I can't figure out why the phone says "No Service". Accessing Settings>Wireless Controls>Mobile Networks>Network Operators, and selecting "Search Networks" result in finding either AT&T or no carrier at all. However, tapping the bottom right corner of the phone (Front Side) gently, on something such as the inner part of the knee, sometimes enables the phone to acquire a network connection. Strangely, placing a call while the phone is connected to a network will put it back in the "No Service" state after only a few seconds, while texting or simply leaving it be will allow it to remain in service much longer. Is there a solution??
