For two months my s6 had no problem.Like any normal smartphones it would connect to pc and can use for data transfer. Yesterday when i connected my s6 to pc it said just cable charging. I removed and connected the cable several times but no luck .Now when i connect my phone to fast charging adapter which came with the s6 ...it says cable charging and takes 1hour 40 mins...Actually it would take only 1hour 20mins. When i connect otg usb (Strontium Nitro 16gb otg usb) nothing happens .it shows only device storage . Guys plzzz help
