So anyone know the prob with 3G auto disabled during call?
I tried googling it.. all i found is for other brands and models. useless for dhd leh
I believe the known issue that you have experienced is due to dual mode transfer setting (ro.ril.enable.dtm) that can be found in the /system/build.prop has disabled in your HTC Desire HD. Enabling this dtm setting will allow voice and data packets transfer simultaneously. However, this is also depends on whether your network provider can support it.

By the way, you can not change the setting if your phone is not rooted.
