I have a question there and although I have a Samsung Galaxy S8 and from tomorrow to tomorrow it does not load on my original power adapter with cable but it charges the USB charging socket of my laptop but only with a charging cable, the power adapter is 100% therefore other phones too sorry now I wonder why my phone is only charging to the USB port would be glad about an answer LG😌
If the phone from the USB jack loads everything is fine!
Swap the defective power supply for warranty, if it is still like the phone then, where is the problem?
First read everything, he writes that the network adapter works on other phones
I read. Correct German would have been easier to understand than a jumbled scribble. What else do you want to do, than first to change the power supply and then the phone to warranty? Possibly. Take back both at once and you should back up your data first.
