While i was trying to change mac address with apps and terminal on my samsung it didnt work.i have the new samsung A5.i have found a method to change the mac address manually on samsung but needs the following:root and a root browser(can be found in playstore.first root your phone, there are alot of methods online to do that, and download esfile explorer(the root browser).when you open esfile explorer swipe from left to the right or press something on top left to open a black window called on top fast access, on this window there is a category called tools press it and now enable "root explorer" and "show hidden files", now change the category to local and press device, now go to efs-->wifi and now youll see 2 files, .mac.cob and .mac.info , in both of these files there should be only you original mac address, open each of these files if necessary,as text then with es note editor and now press on top right and press edit, now just change the mac address of yours to your victims and save these files(but dont forget the original mac address)and get out of esfile explorer and restart the phone to take changes, then go to setting--> about device-->status and youll see that your wifi mac address have changed.this operation can be reverted by doing the same method.
