Asus smartphone cases are known for their solid casing. Even though these smartphones can withstand the occasional bump, they're not fully shockproof. Protect your Asus device with a case and prevent scratches and dents. If you only want to protect the back and sides, go for a back cover. Would you like to protect your entire smartphone? A flip case and book case also cover the screen. Make sure the case you're buying is suitable for your smartphone type.
