Can I check if my phone has spyware?

I'm curious, is there a way for me to verify if my phone has been compromised by spyware? I've been hearing a lot about the risks of cyber threats and I want to ensure my device is secure. What steps can I take to check for any potential spyware and protect my personal information? Additionally, are there any specific signs or symptoms that I should be aware of that might indicate my phone has been infected?
