I have been using my android (Samsung galaxy A7) and whenever I connect it to the lap, it showed me a pop up "Allow the data transfer". all of a sudden it stopped. The phone is charging. I tried with 2 cables. Device driver updated in laptop. USB option Media Transfer Protocol.

Another thing I noticed is the OTG pendrive too doesnt get detected on the phone.

    That sounds like a broken USB connector in the device, making data connection impossible. – Izzy Jul 21 '18 at 19:11
