You can enter the application settings menu by swiping to the right or pressing the burger button 
in the upper left corner.
In the app settings for the IOS system, you have access to the following options:
...
auto ending a call when you press the lock open button;
opening the lock via Bluetooth when you turn on the smartphone screen and the lock is detected;
setting the Bluetooth sensitivity value (from 100 to 50) that stands for the distance (between a phone and a panel reader) at which the lock opening signal will be transmitted and received. We recommend setting a 75 value, as it helps to open only the lock that is close enough to a user phone and avoid all detected locks opening (if a high value is set). The lower value is set, the closer the action radius is;
setting the timeout (from 1 to 10 s) between sending signals for opening the lock (via Bluetooth). So, if you open a lock using UKEY, next time you can open the lock after indicated timeout;
enabling/disabling collapsed banners that change notifications form (they are not full-screen);
...
enabling/disabling the video full-screen option during a call (1st example is video full-screen enabled; in 2nd screen is disabled);
...
Also, in the IOS settings for the app, you can configure the app rights, language and enable/disable CallKit notifications.
...
With enabled CallKit notifications, calls from an app look similar to a simple (system) phone call. If the parameter is disabled, you get a notification as shown on the 2nd screen.
...
In the app settings for the Android system, you have access to such options as:
...
auto ending a call when you press the lock open button;
opening the lock via Bluetooth when you turn on the smartphone screen and the lock is detected;
enabling/disabling hands-free mode that allows opening the lock via Bluetooth when you turn on the smartphone screen (and the lock is detected);
enabling/disabling showing overlay outside of the app. This feature allows calls and notifications over other apps that you are using or when your phone is blocked (with enabled parameter incoming call on your lock screen is look like the 1st example, and 2nd one shows a notification with disabled parameter);
