I have a case and a tempered glass protector. I like the case because it add some grip and my current phone doesn’t do wireless charging so I have a small metal plate between the phone and the case to use a magnetic phone holder in the car. That way I don’t have to glue it tonthe back of the phone and you don’t see it.
I don’t take the extended warranty because I buy my phone unlocked, and my credit card offers an extra year of warranty on top of the one from the manufacturer so I have two years of protection instead of one.
Like selling the account to a spammer lol
