Answer to: Samsung Note 1 losing signalSaw this on an Amazon review - Quote: " I disconnected my phone, removed the old connector and installed the new one. I now have a phone that charges and most importantly the data/internet signal is stronger than ever. BEFORE YOU INSTALL THE CONNECTOR, THERE IS A THIN FILM ON THE BACK OF IT THAT HAS TO BE REMOVED IN ORDER FOR YOUR PHONE TO ATTAIN A SIGNAL FOR DIALING OUT AND RECEIVING CALLS. YOUR DATA/INTERNET SIGNAL WILL BE RESTORED ONCE THE FILM IS REMOVED. Reconnect, insert your sims card and RESTART YOUR PHONE AND YOU ARE GOOD TO GO. For those who had problems, I hope this helps, as a matter of fact i am 100% sure it will help...Good Luck!!!"
