The SXFI AMP will work with most phones and laptops that have a USB Type-C connector. If your phone has a USB Micro-B connector, you will need a USB Micro-B OTG adapter to connect the SXFI AMP to it.
Make sure that the adapter is marked “OTG” as the phone needs the signalling from this type of adapter to switch itself into USB host mode.
The following devices exhibit compatibility issues with the SXFI AMP, and are not supported:
Huawei Honor 9 Lite / P8, P20, P20 Pro, and others in series
OPPO R9, R11s, R17
Sony Xperia XA series and XA1 series
Samsung Galaxy S10 series
