Ok folks, I've been tweaking this for quite a while now and have found only one solution which seems to work close to 99% of the time.
The xv6700 is no good at waking up from sleep or turning itself back on again for a call, which results in the phone freezing when answering calls.
The solution is to purchase an extended battery which should last you possibly all day compared to the smaller battery that comes with the phone.
In the power options, DO NOT TELL THE PHONE TO TURN ITSELF OFF......
No matter when on battery or on external power....leave the phone always on but the backlight you can turn off after "1 minute" on both battery and external power....
