My sketch.js is operationg brilliantly on PC browsers but not on a mobile browser . I am using a Samsung Galaxy S7 and the latest chrome browser on it... Here is the link to my project you might want to check it out yourselves (use right click inspect first for mobile view if you are running it on a PC, before going there) giannispetridis.xyz/Blobsnake/index2.html

I'm not really sure what you're asking. Mobile devices are going to be less powerful than desktop PCs.
You could put together a small example program (note: this should not be your full sketch, just a small program for testing) and post it here, and we can try to find places for improvement. But at some point you're going to hit a limit of what you can do on a mobile device.
