Why Fingerprint Login is not working on my device?
Devices from LG, Sony, OnePlus, Huawei and other manufacturers will work automatically as soon as they upgraded to Android 6.0.
Technical details: SafeInCloud can only use a hardware fingerprint scanner via a dedicated API (Application Programming Interface). This can be either some custom API (like Samsung provided in their Pass SDK) or a standard API, which appeared only in Android 6.0. LG, Sony, OnePlus, Huawei did not provide a custom API for 3rd party developers, so the only hope is waiting for them to upgrade their devices to Android 6.0 with support of the standard Android Fingerprint API.
