font-family: PingFangSC-Regular, sans-serif; line-height: 30px;">和往年一样，近期谷歌放出了新系统 Android 12 的首个开发者预览版，Google 工程副总 Dave Burke 曾表示新系统的目标是为用户提供更好的体验和效能。</span></div><div style="border: 0px; outline: 0px;

letter-spacing: 0px;"><span style="color: rgb(42, 42, 42); font-family: PingFangSC-Regular, sans-serif; line-height: 30px;">虽然幅度不大，但通知中心在 Android 12 中的变化还是存在的。首先是通知条目的布局和字体大小的变化，此外右下角还加入了类似「稍后提醒」的按钮，点击后可以选择在特定时间后发送二次提醒。</span></div><div style="border: 0px;

letter-spacing: 0px;"><span style="color: rgb(42, 42, 42); font-family: PingFangSC-Regular, sans-serif; line-height: 30px;">在 Android 12 的设置菜单中可以找到一个新的安全和紧急情况设置，既包括了快速获取紧急信息（联系方式、医疗细节等），还有车祸检测、危机提醒、无线紧急提醒和新的紧急 SOS 功能。</span></div><div style="border: 0px;

font-family: PingFangSC-Regular, sans-serif; line-height: 30px;">苹果在去年的 iOS 14 中加入了隐私指示器功能，一旦检测到应用调用设备的麦克风和摄像头，状态栏便会出现相应的绿点/黄点提示，同时下拉通知中心还会告知用户哪些应用调用了摄像头/麦克风。</span></div><div style="border: 0px; outline: 0px;
