I had purchased this cellphone 3 years back. as we all no that samsung is a global trusted brand so this is why we purchase samsung products because of reliability and quality. I am gonna tell you about the experience of this phone, after buying this phone it was working very well the speed, camera quality was all good but after 1 year it all changed . first its taking too much time for an app to open, I mean a lot of time and its very laggy and second thing the wifi signal has become weaker its not showing wifi full range as my other phone. if you go to download an app it only shows downloading but in real it doesnt download . I have a pretty bad eperience with this laggy phone, I highly recommend not to buy this phone as it is too expensive and stops working after a few months time, there are better phones than this one so go for others
