A search for "Tough Case for Samsung Galaxy Ace" brought me to this cover. Once the case arrived, it did not fit the phone. It was considerably bigger. The description does not provide details of the models it is compatible with. I have made suggestion to Amazon to mention in the description the phones it is compatible with. Also I have asked them to review their search process which led me to this cover in the first place. The cover is absolutely brilliant but not suitable for Galaxy Ace.
