How do I get ice on my phone?

Excuse me, I'm just a bit puzzled here. Could you please elaborate on how exactly I can acquire ice on my phone? Is there a special app or service that provides this functionality? Or perhaps, is there a way to simulate the feeling of having ice on my phone's screen? I'm genuinely interested in this concept and would appreciate it if you could guide me through the process. Thank you for your time and assistance.
