Why does my game crash on old phones but not mine?

Because you develop and test on a modern device, while old phones have less memory, weaker GPUs, older drivers, and older OS versions that hit limits and behaviors your machine doesn't, like out-of-memory crashes, unsupported features, or driver bugs. These crashes only happen on the old hardware, so they're invisible from your modern testing. Capturing crashes tagged by device from real players is how you see crashes concentrated on older devices.

What Causes Crashes on Old Devices?

Q: How do I fix crashes on old devices?

Capture crashes tagged by device to see which old devices crash and on what, then address the specific causes: reduce your memory footprint for low-memory devices, provide fallbacks or lower settings for unsupported GPU features, and handle old OS quirks. Use impact data (how many players are on each old device) to decide which are worth supporting, and where you can't support a device acceptably, set honest minimum requirements rather than letting it crash.

Quick answer: Old devices crash more because they have less memory, weaker GPUs, older drivers, and older OS versions, hitting limits modern hardware doesn't, out-of-memory crashes, unsupported GPU features, and driver or OS quirks.

A meaningful share of players are on older devices, and those devices crash more than modern ones. The causes come from the ways old hardware differs from your test machine. Here's what causes crashes on old devices.

Why Old Hardware Crashes More

Older devices have less of everything, memory, GPU power, modern features, and run older software, so they hit limits and behaviors your modern machine doesn't.

Less memory, leading to out-of-memory crashes when your footprint exceeds the device's RAM
Weaker GPUs, which may not support features your game uses, or crash under rendering load
Older graphics drivers, with bugs or missing capabilities
Older OS versions, with different behaviors, missing APIs, or their own bugs
Missing hardware features, capabilities your code assumes that old devices lack
Lower performance margins, less headroom, so the device fails under load it can't handle

Each of these is a way old devices differ from modern hardware, and your code hitting one of those differences causes a crash that only old devices experience.

Why They're Invisible on Your Machine

You almost certainly develop and test on a modern device, so crashes specific to old hardware, out-of-memory, unsupported features, driver bugs, simply don't happen for you. A whole segment of players can be crashing while your testing shows nothing.

Bugnet captures crashes tagged by device from real players, so crashes concentrated on older devices surface clearly. Since you can't replicate every old device, capturing crashes from the players who have them is the only practical way to see and address old-device crashes.

Finding and Addressing Old-Device Crashes

Capturing crashes by device reveals which old devices crash and on what, so you can address the specific causes: reduce memory footprint for low-memory devices, provide fallbacks for unsupported GPU features, and handle old OS quirks. Impact data tells you how many players are on each old device, so you know what's worth supporting.

Bugnet ranks device-specific crashes by affected players, so you can prioritize the old devices that matter. So crashes on old devices come from less memory, weaker GPUs, older drivers and OS, and missing features, and addressing them means capturing crashes by device and easing the demands that exceed what old hardware can handle.

Old devices crash from less memory, weaker GPUs, older drivers and OS, and missing features, out-of-memory crashes and unsupported features especially. They're invisible on your modern machine, so capture crashes by device.
