Trust me no one will help you on this kind of a job as for all the experts who know how to cleanly do micro soldering jobs, its not worth it That's what I got back as an answer to my exact problem, I tried doing it my self but when I was half way on putting on a new filter it just flew off my tweezers and never found again so I gave up It's sad that there is no one who actually is willing to help on doing these repairs as they become pro. They would reply to you with ' we think it's a rabbit hole repair and go buy a new phone' Thanks to them for such a wonderful advice and killing the whole purpose and idea of fixing things :-/
As Calvin said, The connectors are comparatively longer than 6 or 5 series, Many of the times the 3rd party replacements don't align good and you don't hear the click sound on snap in. Straighten the connectors again and try to feel the positioning with your finger don't push it hard you will know by the feel when it's ready to go in and snap it in if you don't hear an audible click check again but if you hear a low click you are good. Press the connector with some force now and you should be good. Sal
