I don't have a Samsung cell phone. However, I tend to agree with Jay - the issue may not be the Samsung phone - you may be experiencing the difference between 3G, 4G, and 5G. My cell phone reception is marginal inside my house. I am looking in to getting a cell phone booster for cell phone use in my house. You may want to Google Cell Phone Boosters, and start doing some research - decide whether you can benefit from a booster. |
