Android build on different phones

Hey guys!
So my question is why my app is running on samsung perfectly fine, but on an honor device for example it is little bit laggy and also takes more time to load a scene!

I mean I guess it has to do with the processor or the graphics, but is there anything I could do so that it runs smoothly on every device? (My quality settings for android are on medium)

Thanks in advance!

Each device has it’s own hardware specs. To ensure your game runs smoothly, consider profiling it, and finding out what causing those issues.
