Since ics, i noticed the default browser would sometimes link to something i dis not click. For example if i click something on a page it would actually redirect me to a link beside it like i misclicked but i didn't
Well in that case I guess you have to stick with a different browser. Try clearing cache and data of the stock browser. Might solve the problem.
Normally multi-touch screens do not need calibration.
Especially these advanced screens which work on the principle of static electricity and not pressure like the older generation.
A wrongly calibrated screen would actually mean a visit to a service outlet.
