Clearing Confusion on OTG CableI see a lot of answers here being confused about USB OTG which is just basically a standard for file transfer. OTG is not something different hardware standard. OTG here refers to the software suppor for the microUSB 2.0's data transfer support. This is also used for the charging purpose. Most of the brands such as Xiaomi, Huwei, Oppo and Micromax are releasing the adapter that includes USB point that connects the point for connecting the cable on one end and another end with USB OTG point.
This USB cable can be used for both file transfer as well as device charging. Anyone having confusion please check the image URL below on how the adapter's detachable cable looks.
USB OTG & OTG both cables are same.
Samsung, Moto & Sony doesn't offer detachable charger adapter that has USB OTG point. So it cant be used for file transfer.
