Device Performance Classification

How Luciq classifies Android devices into performance tiers and how data collection is reduced on constrained devices.

On Android, the SDK automatically classifies devices into performance tiers based on hardware capabilities such as CPU, RAM, and memory class. On lower-tier devices, the SDK reduces data collection to protect app performance and prevent issues like ANRs or out-of-memory errors.

This classification is SDK-wide — it applies to all Luciq products, not just Session Replay. See What Gets Reduced for how each data type is affected.

Device Tiers

Tier	Dashboard Label	Data Collected
LOW	Low-end	~30%
AVERAGE	Mid-range	~60%
HIGH	High-end	100%

How Devices Are Classified

Classification runs once per SDK start, based on the device's hardware capabilities.

A device is classified Low-end if any of the following is true:

Signal	Threshold
Android version	Below 5.1 (Lollipop MR1, API level 22)
CPU cores	2 or fewer
Total RAM	2 GB or less

Otherwise, a device is classified Mid-range if any of the following is true:

Signal	Threshold
Android version	Below 7.0 (Nougat, API level 24)
Per-app memory class	160 MB or less
CPU	Fewer than 8 cores, or combined max CPU frequency ≤ 2055 MHz

Everything else is classified High-end.

These thresholds may be tuned in future SDK versions, and specific device models can be re-classified remotely by Luciq.

Emulators

There is no emulator-specific rule — emulators are classified using the same hardware signals as physical devices:

• A default Android Virtual Device (2 GB RAM) is classified Low-end because its RAM is at the 2 GB threshold.
• An AVD configured with more than 2 GB of RAM and more than 2 vCPUs escapes the Low-end tier and is typically classified Mid-range (emulators generally don't expose readable CPU frequency information, so they don't qualify for High-end).

If you don't want your development, staging, or CI emulators classified as low-end, configure the AVD with at least 3 GB of RAM and 4 vCPUs.

What Gets Reduced

When the SDK reduces data collection on a constrained device, the following are affected:

Data Type	Low-end	Mid-range	High-end
Session Replay	Navigation mode only	Configured mode	Configured mode
Session Profiler	~18 seconds	~36 seconds	Full duration
Network and Console Logs	30% retained	60% retained	Full
Repro Steps	30% retained	60% retained	Full

What You'll See on the Dashboard

When viewing a bug report, crash occurrence, or session from a constrained device:

• A device classification badge appears in the details panel showing the device tier and the percentage of data collected (e.g., "Low-end · 30% data collected").
• If session profiler data, repro steps, or screenshots are unavailable due to data reduction, the dashboard displays a message explaining that data collection was reduced on that device to protect app performance.

Device classification is currently available on Android only. This behavior is automatic and does not require any configuration. If you need classification disabled for a specific app (for example, a staging build), contact Luciq support.
