Google's Nexus 6 smartphone is now set to ship at least a week later than originally planned, as the firm struggles to get its flagship Android Lollipop device to market.
V3 contacted Carphone Warehouse to ask why the release was delayed but had received no reply at the time of publication.
Google also did not respond to a request for comment on the reason for the delay.
The Google Play store says that the 32GB model is 'out of stock' while the 64GB model is 'coming soon'.
Another website, called MobileFun, says that stock is expected in two months.
"That looks to be the earliest that we can get the device from our suppliers," the firm said in a statement.
Vodafone states that home delivery will begin from 5 December, while O2 merely says that it is coming soon.
The reasons for the delays are not clear, but it seems possible that Google, or its build partner Motorola, is struggling to ship the phones to key markets, a problem experienced by previous partner LG with the Nexus 4 in 2012.
Another cause of the delay could be that the newest version of Lollipop is causing problems, as many who have updated existing devices have reportedly seen glitches and errors.
Google's pricing for the Nexus 6 is £499 for the 32GB version and £549 for the 64GB version.
The Nexus 6 has a QHD IPS display powered by a 2.7GHz quad-core Qualcomm Snapdragon 805 processor, 3GB RAM, 13MP rear-facing and 2MP front-facing cameras, and a 3,220mAh battery that Google says will last for a full day.
V3 had a hands-on with the device last month and found that, despite some top-end specs and an impressive form factor, the device will face a tough task wooing buyers away from other high-end phones such as the iPhone 6 and Samsung Note 4.
