Samsung Galaxy S2 GT I9100 was the most beloved smartphone of 2012 with ultimate features and specifications. However, it is in the top 15 list of best android smartphones of 2013 also.

Samsung has not yet approved the international warranty scheme. So, it has been a problem for many customers and users of Samsung Galaxy S2 who bought it from foreign countries. Service centers of Samsung completely refuse to accept the warranty of international smartphones of Samsung.

So, they charge for everything what so ever if your Samsung smartphone is in warranty or not.
