Lock screen music issue

Hello i made a kustom lock screen but there are some issues

how to add the network and battery text like original samsung screen ?
how to add the call and camera button ?
how to show music screen playing on the kustom lock screen ?
how to double tap lock screen to close it ?

There’s probably more than one way to do these. For all text, just use a text element with the corresponding formula. Like $nc(carrier, 0)$ for the operator name, BI for battery/charging data. You can do the call and camera icons with the Touch function on an icon to launch the required app. As for the double-tap, this is not available in the app.

how about to show music playng on lock screen ?
