Using this phone now , there are several issues with phone and its servicing, first faced issue with my bettrery within months of purchasing it, screen has to be changed without any reason as it stopped working, thought it has Dolby sound is so pathetic that you can’t even listen to your phone from 6ft away leave away media files.service center never accepted these problem neither did they rectify it, and atlest it is dark spot in the name of 4G compatible handset as it doesn’t even support full fledged 3g, they will not rectify any issues until your warranty expires.
