I have been using the phone for months now and I don't like it at all due to software bugs? my alarm clock doesn't sounds when it's setup, lets say I have it set up from monday to friday at 5:45am and it sounds luckily twice during those 5 days (totally ramdom) so I had to begin using an alarm clock because the one of the mobile phone sucks. besides that without being using the battery saver, some apps doesn't get connected (even if they have all the permissions) until you open them, so whatsapp and even the sms are received only when I open the app. I had the oukitel k10000 and the oukitel k10000max and both of them worked great compared to this one. I have restarted it several times and check the configuration of the mobile phone and everything seems ok and well setup but still it doesn't work properly.
