Yeah they tend to say hard reset or turn touch off high to normal.....well whats the point in having high if its broke.
Again, if you have the issue speak with Nokia.
Its funny its like that issue with the SGS4 with the smeargate saga, I was well behind that with a few others, pushing on sites and driving people to question that issue, in the end one guy got it to hit the media and lol who would of thought it......a fix came not long after
Problem is most companies rush product out, they know we will buy it and look at it as "hey we can update as we go along, just get it out and sell" and the problem is some dont complain to them, so in any companies eyes why bother to fix it if they seem happy with it, thats why you need to get on at them.
