Samsung's new line of high-end tablets has been out for about a month now. The Tab S 8.4 and 10.5 bring high performance and Super AMOLED displays, in thin and light casings. They both have models powered by either the Snapdragon 800 or Samsung's own Exynos 5 Octa 5420.About a week ago, there were some troubling news concerning the Exynos-equipped Galaxy Tab S 8.4 . A user from Russia claimed that whilst playing a 3D game, the slate would go very hot. So hot that it would eventually warp its plastic back cover Similar reports have surfaced on tech forums since, and Samsung has now announced that it's aware of the problem. However, according to Sammy, the super-thin device is not having overheating issues, rather, the warping of the plastic is caused by a defect in a limited number of back covers. Samsung claims it has dealt with the issue and urges anyone who owns one such lemon to go ahead and contact their nearest Samsung Electronics customer service center. We assume that means you'd get a new back cover, rather than a new tablet.Do you own a Galaxy Tab S 8.4? Any heat troubles so far?
