GARD Pro Not Registered

Samsung Galaxy Tab S 8.4Samsung Galaxy Tab S 8.4 is actually a pretty nice tablet for its price range, with an equally comforting spec sheet. The tablet has mostly received positive reviews from all around, however, it takes only one bad apple to spoil the bunch. According to reports, there is at least one faulty Samsung Galaxy Tab S 8.4 out there which is showing symptoms of overheating.

Does the Exynos variant of the Galaxy Tab S 8.4 have overheating issues?

Exynos is Samsung’s in-house processor. It’s been around for quite a while and generally gets used in smaller markets. With the introduction of the Galaxy Tab S series, all of the non-LTE models are using the Exynos processor, no matter what market they are in. The Exynos 5 processor used in the Galaxy Tab S 8.4 tablet is an octa-core processor, so it makes sense that it can overheat if there are some issues with the silicon. This doesn’t seem to be a widespread though. If you look in various Galaxy Tab S forums, there isn’t anyone else really complaining about the device getting too hot.

However, one particular owner is currently having an issue. As you can see from the image below, the thin backplate of the tablet is starting to warp. We will also include the source link below so you can look at the gallery of pictures that he has taken. I am unable to find a teardown of the device, so that we can find what parts are causing this heat issue. Looking at the gallery, it is clear that the backplate has warped in at least two different spots.

Whether this is a hoax (the owner may have just dropped something on the device) or the real deal, we just wanted to pass the information along so you are aware of potential issues. If this ends up turning into a widespread issue then we will be sure to give this topic more coverage. Until then, tell us what you think about the Galaxy Tab S tablets. We have heard a lot of good things about this tablet. Are they meeting your expectations?



  1. I noticed that overheat on my tablet on first day of using it. Im using 10.5 and observed this for more days to come how it goes..

    • Does this happen during a particular usage case? Like, does it overheat when playing games or while watching movies/TV or even while doing casual browsing on the internet?

  2. My 8.4 gets pretty warm but not overheat per say. The back of my tablet is warped though in 3 spots. I bought mine from Samsung direct and was told to RMA it after I sent in pics. Questions is how to determine when I buy a new one at say a retail store if they have the batch that has the production issue, or not. Samsung couldn’t answer that either.
