Call handling
Calls are handled using the Send and End keys as follows:
Send - Answers the incoming call when the phone rings
or there is a waiting call.
- Creates an outgoing call when there is a number
entry window active.
- Puts active call on hold; unholds a held call; swaps
held and active calls.
End - Rejects the incoming call.
- When an active call exists: ends the active call.
- When only a held call exists: ends the held call.
- When both active and held calls exist: ends the
active call, makes the held call active.
A basic rule is that Call handling keys accomplish the same functions whether the
Phone application is on screen or not, so the user need not swap applications for
these operations when using another application. (However, some applications may
override the Send key and use it on a local function: for example, in Messaging, Send
can be used to send a message.)
Volume control
In case the hardware has no dedicated volume keys, the sound volume is adjusted
using the scroll left and scroll right keys. The volume indicator is in the Navi pane.
It is worth noticing that the user must be in the Phone application (or another audio
application) to be able to adjust sound volume if dedicated volume keys do not exist.
The same volume adjustment method is used in other audio applications.
