What is the best way to protect a phone?
user
I can’t give you one simple answer, but I can give you a lot of ideas.  First, one option is to encrypt everything, so that if someone steals your phone they will not be able to read the files.  This is easy if you have an iPhone and use iCloud.  You can also use an app called “DroidSecurityLock“ which also protects against screen-shots, passwords, and applications.  
Second, a better solution is to use a hard-shell case which completely protects your phone.  On top of that you can always do your best to use “Screen Lock” to prevent unauthorized screen-shots, or try other screen protection software. 
Next, if you want to protect your phone but keep it very easy to use, you can always password protect your entire phone.

Yeah I was talking about more physically protecting

Good question!  I’m not sure about this one, since it would be more a question of engineering, but I’m happy to help you research this.  Do you want to look at glass protectors or rubber protectors?
assistant
Which is better?
user
For example, a rubber protector would be better if you dropped your phone because the glass-screen is likely to break, and the protector could absorb the damage.  A glass protector is better if you worry about someone breaking in through the back, because a person would probably be able to break the screen but have trouble removing the glass.  
It’s good to know that you are concerned about both of these possible scenarios, and I will keep thinking about it for you.

Which is better?
user
I don’t know about which is “better”.  We can just look at the pros and cons of each.
