Why would my boyfriend be hiding his phone all the time?

So I've been with my boyfriend for 3 years, everything has been good. Nothing to worry about honestly, but something that bothers me is how secretive he is with his phone. He takes it to the bathroom/shower always. He has a password on his phone and I don't know it. He is guarding his phone like its his life. I'm so confused, worried and angry how possessive he gets about his cellphone. He swears nothing is on it. He gets mad at me and saying I don't trust him when I ask about it. If I even look at his phone screen slightly he gets mad at me. What is this about? I don't actually believe he could be cheating we are together all the time. but not living together so I don't know. He did just delete the Tinder app, I made him delete it after all this time.
What's the deal here?
