Not again .....
My mate showed me his 6 plus at the weekend with exactly this fault.
He went in to see the minimum wage 18 year old "genius" who told him it needed a new motherboard and as it was out of warranty it would be around £200.
I despise companies who use slave labour, sell their products at an exhorbitant mark up, avoid tax and then don't admit their products have design faults and make the customer pay to rectify them.
No more to say really .....
Oh .... bastards!
