With my device, (2204) i confirm that all the problems are solved with vdd1=0 and the default profile.(no overclock)
NO instability, no problems recording/playing video, perfectly smooth and no battery drain.
As soon as i enable vdd1, i cannot play any video, cannot record, many dsp faults and battery drain...

Going back and setting vdd1=1 all the issues start again...

So, same phone, same apps, same clock profile.... only one bit of difference between one working phone and one apparently faulty device.
