Karbonn is hopeless company .no new products are launching nor they are fullfilling cosumers demand of good mobiles and tabs at good rates.If u are going to buy karbonn smart tab 1 please be carefully becasue its not good .display quality is bad, no proper audio output, hangs each and everytime, worst audio quality.i specially did not like this karbonn smart tab 1.its better to invest on some other good tabs .instead of buying such a cheap and worst tab.please do not buy this tab
