Answer to: LCD flex wire broken during glass replacementI am going to try something I have heard about have never needed to try it. But I have this s3 parts phone and lcd is good have the flex to the digitizer is busted. No touch. I will be back with results. Update (02/12/2016): Okay I tried the splicing of the flex wire cable. Noooooooooo! Sobyeah buy a new phone. It is possible to replace the good lcd with a bad one and just very gently remove the wire from the busted lcd, same with the busted one in the old lcd. Replace the working lcd with the old and slip the non busted wire back into place. Use little glue and double sided tape. I will post a pictures soon. And this is something you should only do if you are experienced and bored.
