 ## Version History
 
+- **v1.2** - UTexture2DDynamic integration
+  - Switched `UMosisPhoneTexture` to extend `UTexture2DDynamic` for proper material system integration
+  - Removed custom `FMosisPhoneTextureResource` - using UE5's built-in `FTexture2DDynamicResource`
+  - CPU-based texture upload via `AHardwareBuffer_lock()` and `RHIUpdateTexture2D()`
+  - Fixed stride conversion (AHardwareBuffer stride is in pixels, RHI expects bytes)
+
 - **v1.1** - UE5 RHI texture integration
   - New `UMosisPhoneTexture` using UE5's `IVulkanDynamicRHI::RHICreateTexture2DFromAndroidHardwareBuffer()`
   - `FMosisPhoneTextureResource` for render thread HardwareBuffer import
