OTG (On The Go) is an addition to normal USB that allows one USB device to control another USB device. Basically OTG allows your phone/tablet to be a client when connected via USB to a computer, but OTG allows that same phone/tablet to be the host when certain USB devices get connected to it (because your phone/tablet is essentially a computer itself).
There are certain devices that DO NOT possess the proper hardware/firmware features necessary to work with VigiDrive and its software. We cannot realistically test all Android devices, but most of them will work without any special efforts. Minimum requirements are: Android OS 3.1 (Honeycomb) or newer, a USB port on the device, and access to the Google PlayStore through the device. Hint: From the Google PlayStore, you can download and run a free app called “USB Host Diagnostics” which will perform several tests on your device and see if it will work.
Check for your phone/tablet compatibility below. More devices will be added to the list with time. (If your device is not listed, please check with your device manufacturer for OTG compatibility.)
