Poor contact with headphones on a cell phone. How to clear/resolve a similar issue?

Question

Iron

I tried to clean them as soon as possible and impossible ... And still, when you insert the headphones, the music constantly disappears every other time, then the sound fades, etc. (This is with different headphones, i.e. the reason is 99% in the connector itself). If you press hard and down a little while you keep it working)) Or is it the trouble of all Sony Ericsson? I have an old k550i.

Answer 1

To disassemble the phone, inspect the connector, you will either have to restore the soldering of the connector to the board or replace the connector if the contacts are loose or deformed inside. You can come up with a temporary "collective-farm" solution without soldering, I just took the connector from my laptop and filled it with hot glue along with the plug, I'll take it apart and solder it at my leisure.
