Whenever Google releases a new version of Android for its Nexus devices, it doesn’t roll out to everyone at once. It may take several days before your device receives the update, but you don’t have to wait.
Note that this only works if an OTA (over-the-air) update is actually available – for example, if you’ve got a Nexus 4 running Android 4.2.1 and you haven’t yet received a notification to update to Android 4.2.2. This won’t help if you’re using an Android device that isn’t receiving updates.
Receiving Updates Normally
Android regularly checks for new system updates for your specific device. When a new version is released, you should receive a notification within a few days. This notification appears like any other notification in the notification tray – tap it to install the new version.
However, you won’t necessarily see this notification immediately, even though you may have read about a new update being rolled our to your device.
You can have Android check for a new version by opening the Settings screen. Scroll down and tap About phone or About tablet at the bottom of the list.
Tap System updates and you’ll see when Android last checked for an update. To check for an update immediately, tap Check now.
Ideally, this will find the new system update and prompt you to restart and install it. However, this won’t always work.
In the case of our Nexus 4, it’s been 3 days since Android 4.2.2 was released and Android still isn’t finding the new version.
Force Android to Find the Update
If we waited a few more days, Android would eventually locate the new version and prompt us to update. Google does a gradual roll-out of updates, and it’s clear that our device isn’t at the front of the list.
However, there is a trick we can use to bump ourselves to the front of the list and force Android to find the update.
First, open the Settings screen and tap Apps. Swipe to the left to access the All section, then scroll down, locate the Google Services Framework application, and tap it.
Tap Force stop, and then tap Clear data.
Go back into the System Update screen. Android will say that it last checked for updates in 1969. (This specific time is the Unix epoch, when Unix time started. Unix systems store their times as seconds since 00:00:00 UTC on January 1, 1970.)
Tap the Check Now button and Android should find the update. You can now tap the Restart & install button to install it immediately.
There has been some controversy over whether this trick actually works. We have used this trick on our Nexus 7 multiple times, and we used it to update our Nexus 4 to the latest version while writing this article.
It may not work for non-Nexus devices receiving OTA updates directly from carriers – we haven’t tried that, although some people have reported success.
