Last year my brother bought this mobile for me on my birth day. He gave me a surprise on my birthday. After two months this phone seen its weakness, it goes hang in low range game. One day I was playing WCC game in this mobile and suddenly my phone gone off I tried very much to reopen the phone but I failed. After half hour I connect the mobile with charger than my phone was open. This problem came back again and again and now I totally bored by this mobile so I decide to exchange this mobile with anyother mobile. This is a worse ever product by Samsung. I am very disappoint with this mobile.
