Hello, I'm new to this site but not new to Samsung.
I currently have a Galaxy A17 which is just over 4 weeks old, first used on 21st August 2025. All was well at first but now I have several USB related issues.
I'm constantly getting notifications "The connected usb device isn't supported" even though I have no usb device connected.
The fast charge no longer functions. I'm using the same power source and cable I used to charge my previous phone and I've tried alternative cables and power sources. I've also lost android auto connectivity in my car.
I know the car connections are OK because I've checked them with an old Galaxy A12 I have lying around.
I'm suspecting there's a usb issue with the phone but I cant find any info on Google. My previous phone, Galaxy A16 was returned to the retailer for a refund because the charging port on that failed after only 8 months.
The A12 I mentioned earlier is still functioning, albeit very slowly, and is now about 5 years old.
Has Samsung quality declined over the last few years, or am I just unlucky?
