Almost 3 days clear now, but tbh the issue was not as bad as other owners, so I think thats reason it seems to have stayed fixed.
This leads to one thing, hardware faults, if people still have the issue after the update it goes to show that the issue was hardware from the start, I mean we have the same phone...same update....so why are some fixed and others not.
The update was a work around, I think it was aimed at reducing the issue, so for some it cleared it up, some its a bit better, but for others its back....again if it was nothing more than software issue we would all have fixed phones now.
This also might be the reason I see no word from Nokia saying "this is 100% the fix" I would guess they release it and wait for feedback, maybe they can tweak it more, maybe its as good as it gets now, or maybe they need 8.1 out to tweak it another way?
