Release the volume key button. And now check how OTA updates work. This is another problem though it doesn't happen very often. Sometimes too many people update their software at the same time. So the server cannot get that much load. So you may get unexpected time outs or disconnections. Don't worry about it, it will be okay within a few times when the load will release from the server. You should better wait and try your update sometime later. Make sure you have a strong internet connection.

DPCs can own a fully managed device called a device owner or can own a work profile called a profile owner. Table 1 shows how device owners can manage system updates, while profile owners can only report information about system updates. Your DPC can help IT admins check which devices have pending system updates—and perhaps ask the device users to install critical updates promptly.
Device owners and profile owners running in Android 8. Call DevicePolicyManager. If a system update is pending, the method returns information about the update. After calling getPendingSystemUpdate you can inspect the returned SystemUpdateInfo value to find out more about the pending update. The following example shows how you might find out when a pending update was first available to the device:.
When an update becomes available, the Android system notifies device owners about the new update. In Android 8. The system might call this method more than once for a single update so check the update's status before responding. Call getPendingSystemUpdate to find out more about the system update in the callback. The following example shows how you can do this:. When a system has more than one DPC, for example work profiles on fully managed devices, the device owner and profile owner both receive the callback.
A device owner can control when updates are installed by setting a local system update policy for a device. The system update policy can be one of three types:. The system limits each update to one day postponement. Besides postponement, Android might not be able to install an update for other reasons such as no connectivity, insufficient disk space, or low battery. The system resets the day postponement timer if a different update becomes available during the period—giving IT admins a chance to try the combined system updates.
Once 30 days have passed without a new update, the system prompts the user to install all the pending updates. Later, when a new system update becomes available, the day period begins again. You can set update policies in Android 8. To specify when the device should install system updates, create an instance of SystemUpdatePolicy using one of the three types outlined above. The following code sample shows how you might do this.
To see a windowed-policy example, look at the SystemUpdatePolicy documentation. To change when a device installs updates, you can create and set a new policy. To remove a policy from a device, call setSystemUpdatePolicy passing null as the policy argument. After your DPC removes a policy, the device user sees notifications for any available system updates.
Apps can call getSystemUpdatePolicy to get the current policy for the device. To freeze the OS version over critical periods, such as holidays or other busy times, device owners can suspend system updates for up to 90 days.
When a device is within a freeze period it behaves as follows:. The system enforces a mandatory day buffer period following any defined freeze periods to prevent freezing the device indefinitely. Remember, freezing system updates can prevent devices from receiving critical updates. You set freeze periods on an update policy.
You can't set freeze periods without setting a policy. When the device is outside any freeze periods you set, the normal policy behavior automatic, windowed, or postponed applies.
You can set freeze periods in Android 9 API level 28 or higher. A device owner sets a freeze period on a system update policy before setting the policy for the device. The steps are:. Because the freeze period repeats annually, the start and end dates of the period are represented by month and day values.
The start day must begin at least 60 days after the end of any previous freeze period. The following example shows how you might set two freeze periods for an existing system update policy:.
Both the start day and the end day are inclusive. If the start day is greater than the end day such as winterSale in the previous example , the freeze period extends into the following year.
When setting the system update policy for a device, Android repeats these tests and includes any current or past freeze periods for the device. Android throws a SystemUpdatePolicy. ValidationFailedException when any of these tests fails. To get a list of freeze periods previously set on a system update policy object, all installed apps can call SystemUpdatePolicy. Android uses the ISO calendar also called the Gregorian calendar to calculate freeze periods and it ignores leap years.
This means that February 29th is not recognized as a valid date and is treated as if it were February 28th. Because Android checks for a day interval between past freeze periods, you might not be able to set a new freeze period without first clearing the record of past periods. You can confirm that a device is in a freeze period by checking that the user interface for system updates is disabled.
