MP3 player no longer works properly?

I bought this MP3 player a few months ago

https://www.amazon.de/...07JWKQ251/

For a few days this has suddenly been crazy. In the beginning it was recognized again and again when I connected it to my laptop, but recently my MP3 player is no longer displayed

Then it no longer loads properly or an empty bar is now displayed to me, but it continues to run anyway

I'm afraid my MP3 player will give up its ghost soon

What could be the cause of these problems and can they be resolved?

Your fear is justified, but it is guaranteed. Take him back to the store.

But I bought it from Amazon a few months ago. The return period has definitely expired

No, the guarantee should normally be 2 years. At least 1 year.

The return period is a voluntary offer by the retailer if a product does not appeal. If, on the other hand, a defect occurs, it MUST either be replaced or repaired = "statutory warranty".

Details fill books, so please ask Google for them.

But I ordered it with no guarantee. Amazon says that the return window was closed at the beginning of February because it arrived at the beginning of January

Guarantee and warranty are different things.

Guarantee is voluntary. Warranty is stipulated by law. It can't be deselected for new devices.

It is not a "return" but a "guarantee". The difference is that the device can also be OK for "return". In your case, however, the device is broken.

If you find them stupid, contact consumer protection.

First, I would try a reset. To do this, it is usually sufficient to format the memory on the PC.

If the error remains, then: complain!

The warranty is 2 years from purchase.
