Samsung Note 1 losing signal

Hi, I'm a repair tech and I have done well over 1500 repairs from iPhones to tablets to android phone.You name it I've fix them. I've resolved issue for all sorts of devices, Although there is one issue that I haven't quite found the answer too. That device is the Samsung note 1 i717, here is the issue:

Every time I replace i charging port flex the phone looses signal bars to the point that eventually it just won't make calls.

Does anybody know why device would loose signal after such repair?

Every 3 out of 5 charging port flex I repair so the same thing.

If any one knows how to resolve this issue let me know, please..

Saw 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!!!"

You may not be reconnecting the RF cable that goes to the board correctly, or damaging the connector in removal or reinsertion. Look at the pin/socket of the connectors with a magnifier and see if you see damage.

A lot of newbies forget to reconnect this cable at all, but I'll assume you don't do that!
