Check or change your usb data cable

This is keeping coming without connecting the cable also. You still thing it is cable issue ??

Check your charger cable with other phone that whether charger is working or not.....also check ur phone by connecting other charger or cable...if problem persists restart your phone, this might help....if after all this also problem persists better take it to a service centre

But Is ur phone charging

[vsvermasuraj6]

Actually i have little similar but slightly different concern, My phone is keep showing USB connected and disconnected pop up notification. Even I have not attached charging cable into my phone the same notification is popping up everytime, while putting charge my phone it is taking Cable Charging instead of Super fast charging even Fast Charging is already on into Settings.

This is my concern and I am facing this from last 4-5 days but can't find any solution.

It must be due to some kind of bug...report samsung and they will fix in the next update.

The last update i think we got in May or June. Till then I can't face any issue.
From last week I am facing this issue. So I can't think that this is a any kind of bug and can be fixed via Update.
