• A real incoming-call screen: a call on a locked phone opens full-screen Answer/Decline, and answering starts audio at once.
• Calls arriving while the app is closed are picked up far more reliably.
• Call History shows the correct time, and redial works.
• Android 13+: the app now asks for notification permission, so chat and missed-call alerts arrive.
• Order, contract and repair lists are paged, and the call-customer buttons dial.
• Steadier background location. All traffic over HTTPS.
