SystemProperty

This item will be set into ro.config.alarm_alert of build.prop. \

开关机铃声比较特殊；

开关机是否有铃声是由 ro.config.key_switch_on_off控制〃如果这个值为0〃没有铃声；设为1有铃声；此默认值在perso中的isdm_sys_properties.plf进行设置

开关机默认铃声由 ro.config.switch_on和ro.config.switch_off控制〃这两个值在perso中的isdm_sys_properties.plf进行设置

2.4 拨号界面专属拨号按键音设置

同一行中〃使用逐渐升调的按键音。即： a）1、2、3保持升调 b）4、5、6保持升调 c）7、8、9保持升调 d）×、0、#保持升调

同一列中〃保持同一音调的按键音。即： a）1、4、7、×保持同一音调 b）2、5、8、0保持同一音调
