As GC messages are Garbage Collection messages, which serves
as an automatic memory manager. The garbage collector manages the allocation
and release of memory for an application.It means your app is using memory and
it is being freed by the GC(Garbage Collector).If the memory requirements are
not too high you won't see GC firing up a lot of time to free the memory. We have
checked the SfListView with TemplateSelector , Grid Layout and
IsScrollingEnable is False , also with Framework controls, the GC message
occurs as you have mention . this GC message is common in Android with complex
templates. We have attached the tested sample for your reference which
performance is fine for complex template. Please let us know if your still facing the any issue ,
