Three-way calling. During a call, tap Add call: the caller is put on hold and the keypad opens for a second number. Once the second person answers, Swap moves between the two, and Merge joins all three of you. After merging, each person has their own Hang up button, so you can drop one and stay on the line with the other. Clearer calls on weak connections. Calls now use a modern voice codec when the other side supports it: about half the data of before, fuller sound, and short dropouts are filled in instead of heard as gaps. A call now carries on when your phone moves between Wi-Fi and mobile data, and call audio is marked as voice so Wi-Fi networks give it priority. Taking a mobile call now puts this call on hold properly, so the caller hears hold music instead of silence. During a call you can move the audio between a Bluetooth headset, the earpiece and the speaker. Tasks can be reworded from the phone: open a task and choose Edit. The task list also shows how many are still to do. Each call sends a short, anonymous quality summary so call problems can be looked into afterwards.
