Why should I test on real devices?

Because real devices differ from your dev machine in hardware, performance, optimization, and platform behavior, so they reveal bugs and performance issues your machine hides that your players will hit. Testing only on your fast machine gives false confidence: it does not replicate real-device conditions. Real devices have actual GPUs, chipsets, memory, and sensors (revealing hardware-specific bugs), are slower (especially low-end, revealing performance problems your fast machine hides), use optimized builds (exposing latent bugs the editor masks), and run the actual OS (revealing platform-specific behavior). So real-device testing catches the bugs and performance issues your players will hit that your machine does not show. Since you cannot own every device, pair real-device testing with field capture (catching issues on devices you do not have). Bugnet captures crashes and performance from real devices (your test devices and players'), so the issues that only manifest on actual hardware become visible with the evidence to fix them, giving you the real-device visibility, testing plus field capture, to catch what only happens on real devices, which is why you need real device testing.

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

Capture crashes from real players' devices in the field, which surfaces the issues on devices you do not own with the context to fix them, effectively extending your device coverage. You cannot own every device (especially with mobile fragmentation), so testing alone leaves the long tail of devices uncovered. Field capture closes it: when you capture crashes automatically from real players with device context, the issues on devices you could not test surface in your data (device-specific crashes clustering on particular hardware), with the stack trace and conditions to fix them without owning the device, and per-version tracking confirms the fix worked on that device. Combine this with testing a representative range you can access and cloud device farms. Bugnet captures crashes from real devices with full context and impact ranking, so the devices you cannot own report their issues to you, letting you find and fix device-specific problems across the hardware range you could never own, and verify the fixes via field data, which is how you cover the devices you cannot test on.

How many devices should I test my game on?

Test on a representative range covering common models, low-end and older devices, and major OS versions, and capture crashes from the rest, since you cannot test every device, field capture covers the long tail. The right number is enough to cover the diversity that matters: common device models (where most players are), low-end and older devices (where device-specific crashes and performance issues concentrate), and the major OS versions your players use. You do not need every device, you need representation across the spectrum, plus field capture for the long tail you cannot test. Cloud device-testing services can extend your reach. Bugnet captures crashes from real players' devices with device context and impact ranking, so the issues on the devices you cannot test surface from the field, letting you cover the long tail beyond your physical test devices, and prioritize fixing the device-specific issues hitting the most players, so your testing (a representative range) plus field capture (everything else) covers the device diversity that matters, which is how you decide how many devices to test on.

Do You Need Real Device Testing?

Quick answer: Yes, you need real device testing, your dev machine hides device-specific crashes and performance problems, and field capture covers the devices you can't own.

Testing only on your machine gives false confidence. Here is whether you need real device testing.

Why You Need It: Your Machine Hides Problems

You need real device testing because your dev machine is more powerful and capable than your players' devices, so it hides the device-specific crashes and performance problems that real, especially low-end, devices suffer. Testing only on your machine gives false confidence while issues ship to players.

Bugnet captures crashes from the real devices you cannot test, with device context, so the device-specific issues your machine hides become visible from your players' actual hardware.

What You Can't Test: Cover It With Field Capture

Since you cannot own every device, real device testing covers what you can while field capture covers the rest, the issues on devices you do not have, surfacing from real players. Together, testing a representative range plus field capture covers the device diversity that matters.

Bugnet captures crashes from all players' devices automatically, so the long tail of devices you cannot test reports its issues to you, extending your device coverage to the whole player base.

When You Need It: Always, Especially on Mobile

You need real device testing for any game shipped to real devices, especially on mobile where fragmentation is extreme and device-specific issues are common. The wider the range of devices your players use, the more essential testing on real devices (plus field capture) is.

Bugnet's field capture suits the device diversity of mobile and beyond, surfacing the device-specific crashes across your players' hardware that real device testing alone could not cover.

Yes, you need real device testing, your dev machine hides device-specific crashes and performance problems, and field capture covers the devices you can't own.
