Google’s Nexus 4 has undoubtedly been one of the hottest Android handsets on sale this holiday season, and it’s been selling rapidly since its release back in November. The search giant has even had to apologize for the difficulties LG is facing in keeping up with the impressive demand. Exactly how many Nexus 4 handsets have been sold, however, is somewhat a mystery.

Google never announces its device sales, and LG’s been keeping quiet when it comes to the Nexus 4, too. However, some Android enthusiasts have been keeping track of Nexus 4 serial numbers, and they estimate that around 400,000 units were produced by the end of 2012.

Last Tuesday, a rumor surfaced regarding an exciting new Android handset from Sony that will reportedly offer a 5-inch 1080p display like the HTC Droid DNA. Called the Sony Xperia Yuga, the device is expected to debut in early 2013, but images of its prototype have already surfaced.

Despite its lack of LTE, the Nexus 4 has been hugely popular.

Google’s new Nexus 4 smartphone has been a hugely popular handset since making its debut back in November, but supply issues have somewhat spoiled what should have been a successful launch. When the handset is made available through Google Play, it doesn’t take long for stock to disappear again, and those who do get an order in on time are forced to wait weeks for their device to arrive.

Dan Cobley, managing director of Google U.K. & Ireland, says the “scarce” supplies from LG are “unacceptable.” He’s issued an “unreserved apology” to Nexus 4 customers, but says Google hopes to fulfill “pre-Christmas” delivery promises by sending out a new batch of handsets this week.

Been itching to get the Google Nexus 4 but don’t want to join O2 for some reason? Maybe a contract with Three would be better for you. The carrier has just become only the second in the United Kingdom to offer Google’s latest smartphone, breaking its month-long exclusivity to O2.

Boy, oh boy, just when you thought it couldn’t get any worse Google goes ahead and essentially pulls a bait-and-switch. I’m really not sure what excuse Nexus 4 owners are going to come up with to justify Google’s latest charade but I’m extremely disappointed. What am I making such a fuss about you ask? It’s been discovered that the Nexus 4 does not support USB (for peripherals) despite original documentation clearly stating that it did.
