Cyanogen 13.1 brings new 'Mod' features to the OnePlus One
OnePlus One owners are currently in the process of receiving the update to Cyanogen 13.1. The update includes a number of Microsoft based Mods. For example, with the update Skype calls can start directly from the Cyanogen phone app. If you are in a call with a person using an Android or Cyanogen powered device, you can quickly and easily switch from a cellular voice call to a Skype video call. You can even add more Skype credit to your account directly from Cyanogen's phone app. From the Cyanogen contact card, you can search for a contact and call him/her.
Mods are available on Cyanogen 13 and higher and "are your favorite features right where you expect them." For example, features for your camera are found in the camera app (which is where you'd expect them to be). For more information about Mods, click on the video at the top of this story.
