I have a orange Samsung cell phone. Today I noticed that my cell phone barely had service. It mostly remained at 3 bars. Nothing more and nothing less. What is causing that? And How do you fix it?

That's not really much to go on... do you know the model number? Have you always had 3 bars (out of 4?) for signal strength?

As long as it's always got 3 bars it should always work so what's the problem?

It's probably the area you were in.

Yes, That is probably true! I asked my brother, he has the same phone and his did that also.
