Android Charger incompatiblity

Android 7.0 guideline strongly recommends using USB Power Delivery (USB-PD) method developed by the USB Forum:Android 7 USB implementation guidelines
Type-C devices are STRONGLY RECOMMENDED to not support proprietary charging methods that modify Vbus voltage beyond default levels, or alter sink/source roles as such may result in interoperability issues with the chargers or devices that support the standard USB Power Delivery methods. While this is called out as "STRONGLY RECOMMENDED", in future Android versions we might REQUIRE all type-C devices to support full interoperability with standard type-C chargers.
