How To Turn Off Data Saver Android

Mobile information use is costly and even more so where data plan costs are not affordable by all. Android users need the ability to reduce data use or block it from apps altogether. The Data Saver characteristic in the Android 7.0 release provides this functionality to the user.

The Data Saver characteristic tin exist turned on or off by the user. App developers should use a new API to cheque if Data Saver mode is on. If it is on, the app developers tin handle the situation gracefully past tuning their applications for low- or no-data admission.

Finish users benefit as they will exist able to control which apps can access data in the background and which can access data merely while in the foreground. This ensures desired groundwork data commutation when Data Saver is on per user control.

Implementation

Since the Data Saver is a feature in the platform, device manufacturers gain its functionality by default with the N release. Find the source files in:
packages/apps/Settings/src/com/android/settings/datausage

Settings interface

A default Data Saver settings user interface is supplied in the Android Open up Source Project (AOSP). See the screenshots below for examples.

These screenshots bear witness the Data Saver mode in use.

Apps

Of import: Device implementers should non whitelist apps. Even if they do, users may remove them. Including other apps forces users to decide on which to employ Information Saver.

All app developers must act to implement Data Saver, including OEMs and carriers with preloaded apps. Run across Data Saver on programmer.android.com for app programmer instructions on detecting and monitoring Data Saver states. See the sections below for additional details helpful to partners.

To optimize for Data Saver mode, apps should:

Remove unnecessary images
Utilize lower resolution for remaining images
Apply lower bitrate video
Trigger existing "lite" experiences
Compress information
Respect metered vs. unmetered network status even when Data Saver is off

Conversely, to piece of work well with Data Saver, apps should not:

Autoplay videos
Prefetch content/attachments
Download updates / lawmaking
Inquire to exist whitelisted unless background information is truly part of cadre functionality
Treat whitelisting as a license to employ more than bandwidth

Validation

Implementers tin can ensure their version of the characteristic works as intended by running the following CTS exam:

com.android.cts.net.HostsideRestrictBackgroundNetworkTests

In addition, adb commands can be used to acquit tests manually past kickoff running this command to see all available options:

adb shell cmd netpolicy

For example, this command returns the UIDs of the whitelisted apps:

adb vanquish cmd netpolicy listing restrict-background-whitelist
