This is only my second iPhone. I used a Luvvitt case on my 5s. It worked well for me. I have been looking for a wallet clutch for this 8 Plus. I have not seen any that have totally won me over. I saw several I liked, but they had components that put me off. I have a Luvvitt case that is supposed to arrive tomorrow. With the screen protector and the Luvvitt case, I probably will toss the phone into a small make up bag before tossing it into my handbag. That would be enough to protect it given the way I use it.
I love the gold colour on this phone and the larger screen (so much easier on my failing eyesight), but overall, my 8 Plus seems very much like my 5s. I hope I will not have to upgrade again for at least 5 years! Too expensive.....
