My phone has poor reception. I broke the screen about a month ago, and used a different phone until my new screen came in. it did. and i replaced it, now, i have awful reception. i can basically only get reception outside. any advice? thanks in advance!

Did you replace the screen? Unless you did not properly place the screen in it may have caused the radio antenna problem. The antenna is located in the lower middle section of the device, not directly accessible without opening the phone up. You may have to check to see if something is loose or not connected.
