Why does my game run out of memory?

Because its memory use exceeds the device's available RAM, usually from a memory leak (usage growing unbounded), a footprint too large for low-RAM devices, or spikes from loading too much at once. Running out of memory means your game tried to use more memory than the device had, and the OS killed it (an out-of-memory crash). The common causes: a memory leak (memory allocated but never freed, so usage climbs over a session until it exceeds the limit and crashes, these crashes come after extended play), an oversized footprint (your game's baseline memory use is too high for low-RAM devices, so it runs out on those devices regardless of session length, these crashes cluster on low-RAM hardware), or load spikes (loading too much at once, a big level, many assets, spikes memory past the limit at specific moments). Out-of-memory crashes disproportionately hit low-RAM devices (older or budget phones), since they have less headroom, so the device pattern is a clue. To find your cause, capture the out-of-memory crashes with device and memory context: crashes after long sessions point to a leak, crashes on low-RAM devices to a footprint issue, crashes at load moments to spikes. So your game runs out of memory because its usage exceeds the device's RAM, from a leak (growing usage), an oversized footprint (too much baseline use for low-RAM devices), or load spikes, distinguished by the crash pattern. Bugnet captures out-of-memory crashes with device and memory context plus breadcrumbs, so you can see which devices run out and when (after long play, on low-RAM devices, at load moments), revealing whether it's a leak, footprint, or spike, so you can apply the right fix and verify per version that out-of-memory crashes dropped.

How do I reduce my games memory usage?

Depending on the cause: plug leaks (free what isn't freed), shrink the footprint (optimize assets, load only what's needed, scale settings for low-RAM devices), and stagger loading (avoid spikes), guided by what your captured crashes show. Reducing memory use starts with knowing the cause (leak, footprint, or spike) from your captured out-of-memory crashes, then applying the matching fix. For a leak: find what's allocated and not freed (memory growing over a session), and fix it, free objects when done, release references, dispose of resources, so usage stabilizes instead of climbing. For an oversized footprint: reduce baseline memory use, optimize assets (smaller textures, compressed audio, efficient formats), load only what's needed (don't keep everything in memory, unload unused assets), and offer scalable settings (lower-quality assets or reduced content for low-RAM devices, so they fit within their limits). For load spikes: stagger loading (load incrementally rather than all at once), free old content before loading new, and stream where possible, so memory doesn't spike past the limit at load moments. Across all of these, test on low-RAM devices (where out-of-memory hits hardest) and capture out-of-memory crashes from the field (to see whether your reductions actually helped on the affected devices). So you reduce your game's memory usage by plugging leaks, shrinking the footprint (asset optimization, loading less, scalable settings), and staggering loading, targeting the cause your captured crashes reveal. Bugnet captures out-of-memory crashes with device and memory context, so you know which cause to target (leak, footprint, spike) and can verify per version that your memory reductions dropped the out-of-memory crashes on the affected low-RAM devices, confirming the optimization worked where it mattered.

Why does my game crash on low-end devices but not mine?

Because low-end devices have less RAM (and weaker hardware) than your device, so a memory footprint or spike that fits comfortably on your high-RAM machine exceeds their limited memory and crashes them. The core reason is the memory gap: your development device likely has plenty of RAM, so your game's memory use, even if high, fits with headroom to spare, and you never see an out-of-memory crash. Low-end devices (older or budget phones) have far less RAM, so the same memory use that's comfortable on your device can exceed their limit and trigger an out-of-memory crash. This is why out-of-memory crashes cluster on low-RAM devices and are invisible on your dev machine: it's not that the game behaves differently, it's that the same memory demand crosses the limit on low-RAM devices but not on your high-RAM one. Weak hardware compounds it (less capable GPUs/CPUs hitting other limits). So a footprint that's fine for you is too large for low-RAM devices, a leak that takes a long time to crash your high-RAM device crashes a low-RAM one faster, and a load spike that your device absorbs pushes a low-RAM device over. So your game crashes on low-end devices but not yours because they have less RAM, so your memory footprint, leak, or spikes that fit on your device exceed their limits and cause out-of-memory crashes, invisible on your high-RAM machine. To find and fix it, capture out-of-memory crashes from the field (since they only happen on the low-RAM devices you may not have) and reduce memory use to fit within low-RAM limits. Bugnet captures these crashes with device and memory context, so you can see the out-of-memory crashes on the low-RAM devices you can't reproduce on (your high-RAM machine never crashes), identify the cause, reduce memory use, and verify per version the crashes dropped on those devices, fixing a problem you literally can't see on your own hardware.

What to Do When Your Game Runs Out of Memory

Quick answer: Capture the out-of-memory crashes with device and memory context to see whether it's a leak, an oversized footprint on low-RAM devices, or loading spikes, then reduce memory use for the cause and verify per version.

Running out of memory crashes your game, especially on low-RAM devices, and it's one of the most common mobile crash causes. Finding whether it's a leak or an oversized footprint is the key. Here is what to do when your game runs out of memory.

Capture the Out-of-Memory Crashes With Memory Context

Out-of-memory crashes have a few causes, and you need to know which: a memory leak (usage growing until it runs out), a footprint too large for the device's RAM, or a spike (loading too much at once). Capture the crashes with device and memory context, so you can see which devices run out and under what memory conditions.

Bugnet captures crashes from the field with device and memory context, so out-of-memory crashes show you which devices they hit and the memory situation. Seeing the crashes cluster on low-RAM devices, or correlate with high memory usage, tells you whether you're dealing with a footprint problem, a leak, or load spikes, the first step to fixing it.

Determine Whether It's a Leak or an Oversized Footprint

Distinguish the cause: if out-of-memory crashes come after extended play (memory growing over a session), it's a leak, if they cluster on low-RAM devices regardless of session length, it's a footprint too large for those devices, if they happen at specific moments (loading a level), it's a load spike. The pattern tells you which.

Bugnet captures crashes with breadcrumbs and device/memory context, so the pattern, crashes after long sessions (leak), on low-RAM devices (footprint), or at load moments (spike), is visible. Knowing whether it's a leak, an oversized footprint, or a load spike tells you the right fix, since each requires a different approach to reduce memory use.

Reduce Memory Use for the Cause and Verify

Fix the specific cause: plug the leak (free what's not freed) for a leak, reduce the footprint (optimize assets, load less) for an oversized footprint, or stagger loading for spikes. Then verify per version that out-of-memory crashes dropped, especially on the low-RAM devices that were hit hardest.

Bugnet tracks crashes per version with device context, so after reducing memory use you can confirm out-of-memory crashes dropped, including on the low-RAM devices. This verifies the fix worked where it mattered most, the out-of-memory crashes disappearing from the affected devices in the field data, rather than assuming a memory optimization helped without checking.

When your game runs out of memory, capture the out-of-memory crashes with device and memory context to find the cause (leak, oversized footprint, or load spike), reduce memory use accordingly, and verify per version, especially on low-RAM devices. Out-of-memory crashes cluster on low-RAM hardware.
