Called Samsung today, and they said they were aware of the weak signal issue plaguing the S3. They said at some point Sprint will be releasing a maintenance update. I'm not sure I'm willing to trust Samsung and Sprint to fix this issue, which makes me a little uneasy about keeping my new S3 past the 14 day trial period. I love the device otherwise, but it's current capabilities as a phone are in question. I'm constantly dropping calls in the Denver area because of weak signal strength. Never had any issues in town with my old Epic 4G. What to do?
