In addition to iPhone, WhatsApp has now added the album functionality to Android.
As soon as you send more than four photos to the same person, WhatsApp automatically creates an album. By clicking on the album, the receiver can scroll through the photos.
The feature is available in WhatsApp beta version 2.17.234. An update to the regular version of WhatsApp in Google Play will follow.
IPhone users can already use the album feature since the beginning of the month.
