HTC one of the worlds popular mobile brand HTC 620g is agreat mobile but highly costedBut now u can get this at little less, it has Dual SIM. This is powered by 1.7GHz octa-core MediaTek MT6592 processor and it comes with 1GB of RAM. The phone packs 8GB of internal storage that can be expanded up to 32GB via a microSD card.looks like an exact replica of from glossy plastic build to dual tone. For now a days you will find that the ram and rom are less but HTC always sell their phone at high cost.It has a great display quality and speakers are too good.we can play music in dolby sound I like that feature what I dislike is the ram this should have been more but otherwise it is one of the best mobiles of htc
