What are the best practices for testing on real devices?

Cover a representative range, prioritize by real usage, and lean on field data for the rest. Test on a range of real hardware that deliberately includes low-end and older devices, since problems cluster on the devices least like your dev machine, that's where memory limits, performance issues, and device-specific crashes surface, and your high-end machine hides them. Prioritize the devices your players actually use, the popular phones, common GPUs, and platforms most of your base is on, so your limited testing time covers the most real-world cases rather than spreading thin. And since you can't test everything, let field crash data with device context fill the gaps, capturing crashes from the field means the devices you couldn't test still report their problems, effectively turning your whole player base into device coverage. Real-device testing catches the device-specific problems your dev machine can't reveal, and field data extends coverage to the long tail of devices you can't own, so the practices serve covering the representative range you can (including low-end), focusing on what players actually use, and using field capture to reach everything else, which together catch the device-specific problems that would otherwise ship to players.

Why isn't testing on my own machine enough?

Because your dev machine is the least representative device your players use, typically high-end, well-maintained, and configured exactly how the game expects, so it hides the device-specific problems that affect players. Players run a vast range of hardware, and device-specific bugs cluster precisely on the devices least like yours: low-end phones with tight memory (where out-of-memory crashes and performance problems occur), older GPUs with driver quirks (where graphical glitches and crashes occur), varied OS versions (where API differences cause issues). None of those problems appear on your machine, which has the memory, performance, and current configuration that the affected devices lack, so testing only there gives false confidence and ships device-specific crashes and performance problems you never saw, while most affected players never report them. The gap between your hardware and your players' hardware is exactly why device-specific problems are so common and so easy to miss, your testing environment doesn't exercise the conditions where they occur. The fix is testing on real varied hardware (especially low-end devices, where problems concentrate) and capturing crashes from the field with device context (so the devices you couldn't test still report their issues), which together reveal the device-specific problems your single high-end machine conceals. Testing only on your own machine isn't really testing what players experience; it's testing the best case, which is why real-device testing and field data are essential to catch what affects the full range of devices your players use.

How do I cover devices I can't physically test?

Let field crash data do it, capturing crashes from the field with full device context effectively turns every untested device into part of your coverage. You can't own or test every device your players have, the range is too vast, but if you capture crashes from real players with device context (model, GPU, OS, memory), then when something breaks on a device you've never seen, the crash report arrives with the device details and stack trace anyway, so the device reports its own problems even though you couldn't test it. This turns your entire player base into a device test matrix that surfaces problems automatically after launch: a crash clustering on a particular device, GPU, or OS version stands out in the field data, telling you it's device-specific and pointing at the cause, so you can fix it for that hardware without ever having owned it. Combined with deliberately testing a prioritized range of real devices before launch (covering the devices most of your players use, including low-end ones), field data ensures the long tail of devices you couldn't physically test still tells you when it has a problem, so you're not blind to device-specific issues on hardware outside your test set. The two work together: pre-launch real-device testing catches the device-specific problems you can on the devices you can get, and field crash capture catches the rest on the devices you can't, across your whole audience. This is how a small team achieves broad device coverage despite being unable to own every device, by testing the representative, high-usage devices it can and using field data to cover everything else, which is essential given the impossibility of testing the full fragmented range of hardware players use, especially on mobile.

Best Practices for Testing on Real Devices

Quick answer: Test on a range of real hardware including low-end devices, prioritize what your players actually use, and let field crash data fill the gaps. Real-device testing catches what your dev machine hides; field data extends coverage.

Testing only on your own machine ships device-specific bugs, since your hardware is the least representative device your players use. Here are the best practices for testing on real devices.

Test on a Range Including Low-End Hardware

Problems cluster on the devices least like your dev machine, the low-end and older ones, so test on a range that includes low-end hardware. That's where memory limits, performance issues, and device-specific crashes surface, so testing there catches the problems your high-end machine hides.

Bugnet captures crashes with device context, so device-specific issues are identifiable. Testing on low-end hardware deliberately catches the problems your high-end dev machine hides, which are exactly the ones that generate crash reports after launch.

Prioritize the Devices Your Players Actually Use

You can't test every device, so prioritize the ones your players actually use, the popular phones, common GPUs, the platforms most of your base is on. Testing the devices with the most players covers the most real-world cases for your limited testing time, rather than spreading thin.

Bugnet's device data shows you which hardware your players are on, so you can prioritize your test matrix by real usage. Prioritizing by real usage is what makes limited real-device testing cover the cases that matter most to your actual audience.

Let Field Crash Data Fill the Coverage Gaps

You can't cover everything players have, so let field crash data fill the gaps, capturing crashes from the field with device context means the devices you couldn't test still report their problems. Field data turns your whole player base into device coverage you couldn't otherwise afford.

Bugnet captures crashes with full device context from real players, so untested devices surface their issues. So practice testing on real devices by covering a range including low-end, prioritizing what players use, and letting field data fill gaps, catching device-specific problems your dev machine hides.
