The reason why anyone would want to get their hands on a Nexus device is for the unadulterated Android experience, not to mention the bragging rights of being able to get the latest Android updates ahead of everyone else. Unfortunately it seems that rule only applies if you were to buy it from Google themselves.
With the Nexus 6, Google has decided to make it more widely available on carriers, unlike the Nexus 5. However if you were to buy it from a carrier at a subsidy, it also means that your updates could be delayed. This is according to a recent update in their Android release policy as spotted by the folks at Android Police.
The policy has recently been updated where Google has added the sentence that says, “Based on your carrier, it may take longer than two weeks after release to get an update.” Updates via carriers are notorious for taking a longer time. This is because carriers usually have to approve the update before rolling it out to their customers.
This is versus phones bought outside of carriers where users will only need to wait for their OEM to push it out. However we should note that this only applies to OTA updates and users who wish to download the update directly from Google or their OEM are welcome to do so. If this sounds like a hassle to you, then perhaps buying it outright from Google or a third-party retailer might be a better way to go.
