Hey guys!! I am using HTC Ozone xv6175 mobile phone and I have two questions to ask you guys; one is that I don’t know how to unlock it and the second question is that what can do to hard reset the HTC Ozone? I have a lot of stuff like unwanted settings and all. So I want to reset the phone but I am not finding the options. Also explain if I would reset the settings, will it delete my contact or will it remain in my mobile phone?
