I have Samsung Galaxy s4. Phone works properly but since 13th July there is no net work connection,

I showed it to the service station, they people could not recognise the problem then I moved to many shops but no one able to recognise the problem, please help to solve the problem.

Is Samsung Galaxy S4 still a good buy?

Samsung Galaxy S4 costs now Rs16,000 as now on Amazon.in. Is it best in its range?
