http://forums.androidcentral.com – Hello, I recently repaired the usb input part of my nexus, it charges perfectly now.. but i think i have dont something to the reception part of the phone, im getting greyed out bars, data turning off and on, it seems like i have to send a message for the reception to turn on. I really dont want to get rid of it, I love my nexus, but having a phone with no reception is pretty pointless. Was wondering if anyone knew where the radio part is on the i9525, so that when i pull it apart i can see if something is touching? Any help would be awesome, Cheers (HowTos)
