Yesterday I installed a new screen on my Blackberry 9630. The new screen works great but the phone now has half the reception it did before I did the screen switch. I reopened the phone to check the connections, especially the antenna wire. What is going on? I live in a wooded area where service is sketchy to begin with.
Sounds to me like maybe you somehow managed to damage your antenna when you installed the screen. The good news is replacements can be had pretty cheaply.
