✦ UNITY CRASH & LAG FIXES
Unity Game Crashing or Lagging on Phones? We Fix It.
Profiling-driven fixes for crashes, memory problems, frame drops and slow loading in Unity mobile games.
In Short
Velocity Technosoft fixes Unity games that crash, lag, overheat or load slowly on Android and iOS. We reproduce the problem on real devices, read crash logs and profile CPU, GPU and memory to find the cause, then fix it: memory leaks and out-of-memory crashes, garbage-collection spikes, heavy rendering, oversized textures, plugin conflicts and ANR errors. Many of these problems appear in games built quickly with AI-generated code.

What We Deliver
Crash Fixing
Crash logs, ANRs and native plugin conflicts diagnosed and fixed.
Memory Problems
Leaks and out-of-memory crashes on low-RAM phones fixed.
Frame Rate
Rendering, scripts and physics optimized for stable FPS.
Overheating & Battery
Lower CPU and GPU load so phones stay cool.
Load Times
Faster startup and scene loading with smarter asset loading.
Build Size
Smaller downloads through compression and asset cleanup.
Is This You?
- The game runs in the editor but crashes on some phones
- Google Play Console shows ANRs or crash spikes
- Frame rate drops during gameplay or effects
- Phones get hot after a few minutes of play
- Loading takes too long and players quit

How It Works
How we find the cause
We reproduce the problem on the affected device, read Logcat, Xcode and Play Console crash reports, and profile with the Unity Profiler, Memory Profiler and Frame Debugger. Guessing wastes time; measuring shows which fix actually matters.
Most common fixes
Compressing and resizing textures, removing memory leaks from events and static references, pooling objects instead of instantiating them, reducing draw calls with batching and atlases, simplifying shaders, baking lighting, moving work out of Update and loading assets asynchronously with Addressables.
Testing on real hardware
We verify every fix on low-end and mid-range devices, not just flagship phones, because that is where most players are and where most crashes happen.

Frequently Asked Questions
Why does my Unity game crash on Android but not in the editor?
The editor runs on a powerful PC with lots of memory. Phones have far less memory, different GPUs and stricter rules, so oversized textures, memory leaks, unsupported shaders or native plugin problems only appear on device. We reproduce the crash on real devices and read the logs to find the cause.
Can you fix lag in my Unity mobile game?
Yes. We profile CPU, GPU and memory on device, then reduce draw calls, optimize shaders and lighting, remove per-frame allocations and tune physics until the frame rate is stable.
What causes ANR errors in Unity Android games?
ANRs happen when the main thread is blocked for too long, often by heavy loading, synchronous network calls or plugins. We move the work off the main thread or spread it out and verify the fix in Play Console.
My game was built with AI tools. Is that why it lags?
Often, yes. AI-generated Unity code commonly searches for objects every frame, creates garbage constantly and runs logic in Update that should be event-driven. These patterns are easy to fix once identified.
How much does Unity performance fixing cost?
A profiling audit with key fixes typically costs from about $300 to $2,000, depending on the size of the game and the number of problems.
How do I get started?
Send your build or project and the devices where problems happen. You receive an audit plan and estimate within 24 hours.
