No. What you see is what you get.

Get specs which u think u can live with, don't go under.
For instance, if u think an A10 is good enough u could he very disappointed later on. Or with 512MB RAM may not be enough for certain Apps. Or a 4GB NAND. Or lack of microSD, ffc, Wifi n, Bluetooth.

My last advice is to not trust the salesman, they are used to lying about specs and never accept a refund or warranty. What you see is literally what you get.
