Google reported its quarterly earnings this week and, during the company’s earnings call, chief financial officer Patrick Pichette addressed some concerns with the shortages of the Nexus 6. The device launched as a flagship Android 5.0 Lollipop smartphone in 2014 but has been incredibly hard to come by. Each time stock is replenished, it’s quickly sold out again – often within minutes or hours.

“While Nexus 6 was well received as a new phone, we had real issues and were unable to secure sufficient inventory to meet the demand that we had forecasted,” Pichette said. He didn’t explain whether or not that meant that demand is far exceeding earlier models, such as the Nexus 5, which was also in short supply at first, or whether Motorola simply couldn’t build enough. PCWorld rightly suggests that perhaps carriers are muddying up supply; earlier models weren’t sold as widely as the Nexus 6 is.

Pichette didn’t say whether or not Motorola and Google will iron out the kinks in supply or what exactly the hold up really is for the Nexus 6. Hopefully things run a bit smoother in 2015.
