Microsoft is updating its Windows software for cellphones to accommodate larger devices, and make it easier for motorists to reduce distractions while driving.

It’s the third update to Windows Phone 8 software since the system’s release a year ago. Devices with this update will start appearing in the coming weeks, and older phones will be eligible for a free upgrade, too.

Something that may appeal to motorists — a new Driving Mode will automatically silence incoming calls and texts so that you can focus on the road. You also can configure the feature to automatically send out a reply to say that you’re driving.

It can be activated automatically when the phone is linked wirelessly with a Bluetooth device in the car, such as a headset. — AP
