How do I get rid of this notification, the otg is off

Your charging port needs cleaning. Blow hard into your charging port to clear out any smudge, debris or dust that may have accumulated over time. Be careful not to blow in spittle or liquid from your mouth.

You may also need to clean with a cotton wool rolled on a needle if first method doesn't work.

Thank me later.

Thanks bro,will try it out
