Device Metadata

Netmera SDK automatically collects key metadata from user devices to help you deliver smarter segmentation, real-time personalization, and meaningful analytics. These predefined system attributes serve as foundational building blocks in audience targeting, behavior tracking, and campaign optimization.

Key Advantages

Device metadata plays a foundational role in how Netmera enables data-driven customer engagement. This information allows businesses to:

• Deliver relevant content: By understanding the user's device, operating system, and location, you can adjust your messaging strategy to match the technical context of the recipient.

• Improve segmentation accuracy: System-level data supports the creation of dynamic audiences based on attributes like OS version, app version, device region, or language.

• Enhance analytical depth: These fields help enrich dashboards and reporting by enabling breakdowns by platform, version, manufacturer, and more.

• Support targeted debugging: Understanding which environments are affected during technical issues (e.g., crashes on specific devices or OS versions) speeds up resolution time.

Collected Fields

Field	Description
appV	Application version (e.g., 4.3.3.0)
mdl	Device model code (e.g., T782H)
lang	System language setting (tr_TR, en_US, etc.)
mnf	Device manufacturer (TCL, Apple, Samsung, etc.)
oc	Operator code (MCC + MNC as integer, e.g., 28502 = Operator TR) Note: Deprecated in iOS 15.4+
oper	Mobile operator name (e.g., Operator TR) Note: Deprecated in iOS 15.4+
osV	Operating system version (e.g., Android 11, iOS 16.5)
psV (Android only)	Google Play Services version
rgn	Region/country code (TR, US, DE, etc.)
tzid	Time zone identifier (e.g., Europe/Istanbul)

About oc (operator code) and oper (operator name) Parameters

• iOS: These fields are collected only on iOS versions 13 through 15.3. As of iOS 15.4, Apple has deprecated access to this data due to privacy policy updates.

• Android: These fields are still supported and continue to be collected.

Common Use Cases

Device metadata contributes to several critical use cases across marketing, analytics, and development teams:

1. Version-Based Targeting

Use App Version and Operating System Version to:

• Identify users on outdated versions and prompt them to upgrade.

• Run A/B tests for new features based on OS or app version compatibility.

2. Region and Language-Specific Campaigns

Use Region Code and Device Language to:

• Automatically localize message content according to the user’s language settings.

• Filter or exclude users in unsupported countries or regions.

3. Telecom-Specific Analysis (Android Only)

Use Operator Code and Operator Name to:

• Analyze user distribution by mobile carrier.

• Correlate user engagement or churn with specific telecom providers.

Note: These two fields are only available on Android and iOS versions 13 through 15.3. They are deprecated on iOS 15.4 and later due to Apple’s privacy restrictions.

4. Device-Specific Performance Analysis

Use Device Model and Device Manufacturer to:

• Detect patterns in performance issues or crashes linked to specific devices.

• Adapt in-app experiences or campaign content based on device capabilities (e.g., optimize for low-end vs. high-end devices).
