Huawei mate 20 lite, headphones are not going to go anymore?

Have restarted the phone 2 times, looked in the aux connection dirt o. Ä.

At my friend's headphones went, and his with me.

Recently, they also worked for me.

Who go by friend?

Conversely, your headset with friend…

I had something with USB mice… I had already explained three for Schott.

There must have been some coke on my socket.

Soak old toothbrush with spirit. Never enter directly into the device. Something shake off that she is still wet but nothing comes directly into the device.

Clean the socket and pray that the contacts will work again.

Of course, also clean the plug.

With a little luck that will be enough.

My mice. Oh wonder. Work again. Luckily I have not thrown it away yet.
