How to return the micro usb connector to its previous state?

Question

Do it yourself

When I insert a micro usb charger into a smartphone, there is no reaction. If you press hard inward, then only then it starts to charge. Before that, I just pulled the dirt out of the connector with a needle and definitely didn’t touch anything, however, even before that, everything was not all right, I had to slightly tilt the plug in the connector to make everything work.
And this, that he had to be tilted, it is also not clear why it began to happen, he never treated the connector harshly. The connector itself sits firmly inside, does not hang out a bit, only the plug inside can move. I tried to clean the contacts with a needle, dripped wd-40, cleaned with ammonia - it did not help.

Answer 1

Open and look. Maybe a replacement connector.
Cables often die, try a different cable first to isolate the problem.
WD-40 is bullshit. But ammonia - in vain, most likely it will devour the tracks in the device ...

Answer 2

most likely there was a so-called "disconnection". due to loose connector. try to give it for soldering (minimum) or for replacement with track recovery (maximum) of the USB connector on the smart board.
