First of all, its not korean phone, it is american version. It is with complete box and accessories, One of the best phone by LG, and one of the biggest competitor for samsung s4, note II etc. Please see the specs at gsmarena. It is Gorilla Glass II and I know it doesn't need protection. I have been using Droid phones for more than almost 2.5 years. My previous phones are HTC hero - Samsung S -Samung SII - Samsung SIII. Still have SII with me and using both.
