Samsung Galaxy A53 USB (dust-humidity) error

[SorinFCB7]

Hello!

I have a Samsung Galaxy A53 bought a year and a half ago.

For about 4 days, i have a problem with this phone. Sometimes, after long usage i receive the notification about ("check USB port for dust or humidity"). 

The problem is next: after installing OneUI 6.0 i can swipe this notification and the phone  will work normally (i can charge the phone after swipe notification). If i don't swipe, i can't charge it.

I think this is a system problem or something else, because in 4-5 days everything (dust, humidity) from USB disappeared 100% after so many days. I can also use and charge the phone normally if i swipe de notification.

What can i do in this case?

Another thing important to say: after first 2 days with constant appearing notification, yesterday and today appears only one time. In this time, i used the phone normally, charge it, everything.

Do check the charging port via a torch just in case @SorinFCB7 and perhaps run the diagnostic tool found in your Samsung Members App. 

If I can be of any further help then please don't hesitate. Take care.  😎
