How do I fix device-specific crashes?

Capture crashes with full device context (device, GPU, OS, memory) so device-specific crashes cluster on the affected hardware, group them and look at the device breakdown to find the configuration pattern (a particular GPU, OS version, or memory tier), and then fix the config-specific code path or guard it by disabling/substituting the problematic path on those devices. Since these crashes don't reproduce on your machine, you fix them from the field data and the device pattern, not by reproducing them.

Why can't I reproduce crashes that happen on certain devices?

Because your dev machine is a single configuration, and the crash is specific to a different GPU, OS version, or memory tier you don't have. Device-specific crashes only trigger on the affected hardware, so you can't reproduce them locally no matter how you try. The way to fix them is to capture them from the field tagged by device, find the pattern (which hardware crashes), and work from that data and the device context, fixing or guarding the path on the affected configurations.

How do I find which devices a crash affects?

Capture crashes tagged by device, GPU, and OS, then group them and look at the device breakdown. Device-specific crashes cluster, all on one GPU family, below a certain memory size, or on a particular OS version, so the distribution reveals exactly which configurations fail. That pattern both confirms it's a hardware-specific issue and tells you which hardware, which is the key clue for fixing a crash you can't reproduce. Ranking by affected players then tells you which configurations to prioritize.

Tips for Fixing Device-Specific Crashes

Quick answer: Capture crashes tagged by device, GPU, and OS so device-specific crashes cluster on the affected hardware, find the configuration pattern, and fix or guard the code path those devices hit. You fix them from the field data, not by reproducing.

Crashes that only happen on certain devices are maddening because they don't reproduce on your machine, you lack the triggering hardware. The key is working from the field data. Here are practical tips for fixing device-specific crashes.

Capture the Hardware Context

A device-specific crash is unfixable without knowing the hardware, the device, GPU, OS, and memory where it happens. The first tip: capture full device context with each crash, so 'it crashes for some players' becomes 'it crashes on these GPU families', a lead you can act on.

Bugnet captures device, GPU, OS, and version context with every crash automatically, so device-specific failures arrive with the information to identify the pattern. Since these crashes don't reproduce on your hardware, the captured context is the only practical way to handle them.

Find the Configuration Pattern

Device-specific crashes reveal themselves as a cluster. The tip: group crashes and look at the device breakdown, a crash that only happens on one GPU family, below a certain memory size, or on a particular OS, turns a baffling intermittent crash into 'this fails on this hardware,' which points at the cause.

Bugnet groups crashes by signature and shows the device distribution, so a configuration-specific pattern stands out immediately. Seeing the pattern is what tells you it's a hardware issue and exactly which hardware, the key to fixing a crash you can't reproduce.

Fix or Guard the Affected Path

Once you know which devices crash and why, the tip is to fix or guard the config-specific path, fix a shader one GPU mishandles, reduce memory for a device that exceeds its limit, or guard the path by disabling or substituting it on the affected configurations. Either way, the targeted crash stops.

Bugnet ranks device-specific crashes by affected players, so you fix the configurations that matter most first. So fix device-specific crashes by capturing device context, finding the configuration pattern, and fixing or guarding the affected path, resolving crashes you could never reproduce yourself.

Capture crashes tagged by device, GPU, and OS so they cluster on the affected hardware, find the configuration pattern, and fix or guard the path. You fix device-specific crashes from the field data, since they don't reproduce on your machine.
