I went to Samsung cafe to upgrade my tabs4 to tabs6, my tabs4 8 months
old for exchange the quote 27000 INR which I was purchased 57000 INR for
new tabs6 60000 INR with out any discount so I understood there is no
resale value for Samsung Electronics...
Iam using tab s4 Assistant menu not working and some application
frequently closing automatically so I request you to update the software
of lastest version and this tab not productive or user friendly.
