How do I prevent device-specific crashes?

Test broadly, capture device context, and use the pattern. Test on a range of real devices including low-end, older, and different-GPU hardware where these crashes live, since they're invisible on your dev machine, this catches many before launch. Capture crashes with device context, model, GPU, OS version, from the field, so when you can't test a device, its crashes still report themselves and you can spot when a crash clusters on specific hardware, which is most of the diagnosis. And use the device pattern as a clue to fix the cause, a crash on one GPU family suggests a graphics issue, on low-memory devices a memory issue, on one OS version an API change, then verify it stops on those devices. Device-specific crashes are invisible on your machine but entirely findable and preventable with field device data.

Why does my game crash on some devices but not others?

Because those devices differ from yours in a way that triggers a crash your hardware doesn't. Common causes are GPU and graphics-driver differences (a rendering path that fails on one GPU family), memory limits (low-memory devices crash where yours has headroom), OS-version differences (an API behaves differently or is missing), and other hardware quirks. Your dev machine is just one configuration, so any crash specific to a different configuration is invisible to you, and most affected players never report it. The way to see and prevent these is capturing crashes with device context from the field: when crashes cluster on a specific device type, GPU, or OS version, the pattern both confirms it's device-specific and usually points at the cause, so you can fix it for the affected hardware.

How do I find what's causing a crash on a specific device?

Capture crashes with rich device context and read the clustering pattern, which usually points at the cause. When you have the device model, GPU, OS version, and memory for each crash, a device-specific crash reveals itself by concentrating on a particular configuration while other players are fine, and the nature of that configuration is the clue: clustering on one GPU family points toward a graphics or driver issue, on low-memory devices toward an out-of-memory problem, on a specific OS version toward an API or platform-behavior change. This turns 'why does it crash on that device' from a blind hunt across your whole codebase into a focused investigation of a specific subsystem on specific hardware. Once you fix it, the device context also lets you verify the crash stops on those devices, confirming the prevention worked.

How to Prevent Device-Specific Crashes

Quick answer: Test on a range of real devices, capture crashes with device context so you can spot clustering on specific hardware, and use the pattern to fix the cause. Device-specific crashes are findable with field data.

Some crashes hit only specific devices, GPUs, or OS versions while everything else runs fine. These device-specific crashes are baffling without device data and preventable with it. Here's how to prevent device-specific crashes.

Test on a Range of Real Devices

Device-specific crashes happen on hardware unlike your dev machine, so they're invisible until you test on a range of real devices, including low-end, older, and different-GPU devices where these crashes live. Testing broadly before launch catches many device-specific crashes that your single dev environment can't reveal.

Bugnet captures crashes with device context, so even pre-launch testing surfaces device-specific issues clearly. Testing on varied real hardware prevents the device-specific crashes you can catch beforehand, the ones that only appear off your high-end machine.

Capture Crashes With Device Context to Spot Clustering

You can't test every device, so capture crashes with device context, model, GPU, OS version, from the field. When a crash clusters on a specific device type while others are fine, you've identified a device-specific crash and where it lives, which is most of the diagnosis.

Bugnet captures device, GPU, and OS context with every crash, so clustering on specific hardware is visible. Capturing device context is what makes device-specific crashes findable at all, since without it a crash hitting one GPU family looks like random noise rather than a clear pattern.

Use the Device Pattern to Fix the Cause

The device pattern is itself the clue: a crash on one GPU family suggests a graphics issue, on low-memory devices a memory issue, on one OS version an API change. So use the pattern to find and fix the device-specific cause, then verify the crash stops on those devices, preventing its recurrence.

Bugnet ranks issues by affected players and shows device breakdowns, so you can prioritize and diagnose device-specific crashes. So prevent device-specific crashes by testing on real devices, capturing device context to spot clustering, and using the pattern to fix the cause, turning baffling crashes into findable, preventable ones.

Test on a range of real devices, capture crashes with device context to spot clustering on specific hardware, and use the pattern to fix the cause. Device-specific crashes are invisible on your machine but findable with field data.
