I am using htc 620g from last 1.5 years . The sound reception is very poor now. Although it is very easy to use so it is users friendly . This mobile is available in only 2 colors and design is not so cool when we compare with latest models . It has 1 gb ram which is very low . The hanging problem is very high now . Its looks is a little bit cool and feels like you are using branded mobile. But when I see much better and latest mobile , it does not stand anywhere . I think from this rang we have much better mobiles available in market.
