Faulty Tablet

I consider myself one of the biggest Samsung supporters. The only brand you see in my house is Samsung; dishwasher, microwave, stove, 2 50+ inch tv's, several smartphones for me and my family, the list goes on.<br> <br> 18 months ago I purchased a Galaxy Tab S, a week later it started turning itself off at random and can't be used for a while. When you turn it back on it does the same. I reported this to Samsung and was advised to book it into a service centre which I did. Since then the phone has spent a combined amount of time of 4 months in and out the service centre. The last time which was late last year. I got it back after the boad was replaced; it worked for 2 days now we back to the same issue.<br> <br> I have been more than satisfied with Samsung products until now, this experience with the Tab S has left me with a bad taste in my mouth. I don't know what to do anymore, I have paid for this product and I have barely used it over the last 18 months and Samsung fail to see that it is faulty. I keep getting sent to the service centre where they clearly can't repair it.<br> <br> I may have to reconsider my tablet selections in future, what a shame. Anyone else had this else experienced this???<br>
