Looks like Instagram is adding one more feature that pits it up against Snapchat. TechCrunch has spotted icons in the Android version of theapp that shows the company is working on calling features: one for traditional audio calls and one for video calls as well. The tech site speculates Instagram might be considering putting this into its Direct Messaging system to put it squarely up against Snapchat. This isn’t the first time this option has been talked about, though. Support for these features have been spotted in testing last month.
