  Single USB/Charging port and AMOLED task bar burn in are reasons enough to avoid this.

      AMOLED still do burn in, because that's inherent to how they function; each pixels degrade when they are used and the rate at which they degrade is different. More specifically, blue ones have shorter lifespan than other subpixels (RGB).

      I am not disagreeing that it's definitely something that happens less nowadays. The lifespan of those sub-pixels have improved heaps (though, I still think blue one is the worst one). Though, the screen quality still deteriorate. Blue becoming less prodominant means the screen would get a "yellow tint". If you have one image long enough on the screen, it'd get "burned in". Because that area would have degraded differently to surrounding areas.

        @erroorfree: Image retention is kinda different… AMOLED will burn in because each individual pixels turn on or off and they degrade blah blah. That's permanent. The best you can do is degrading surrounding areas to match that.

        I did hear image retention on LCD can happen in similar condition, though they are considered to be a temporary thing, I've heard. Though my knowledge of these are from my interest on mobile device market (since LCD vs AMOLED, people will always bring up burn in and real black), so not too sure about TVs and whether that'd apply to TVs as well.

        @Oversimplified:

        Yes, LCD burn in is almost always temporary and can be removed by display opposite colours.

        The only "fix" for AMOLED screens is to damage the remainder of the screen to match the burn in.

      amoled burn in days are long gone.

      Funny, Samsung's own support page acknowledges the problem, "Leaving the touchscreen idle for extended periods may result in afterimages (screen burn-in) or ghosting. Turn off the touchscreen when you do not use the device."

      http://www.samsung.com/us/support/answer/ANS00048253/

      But nah, you know better, the problem is long gone, right?

        For comparison, here's what's in the manual for their LCD tablets:

        "Leaving the touch screen idle for extended periods may result in afterimages
        (screen burn-in) or ghosting. Turn off the touch screen when you do not use the
        device."

        http://downloadcenter.samsung.com/content/UM/201607/20160711…

        Look familiar? You'll find that same warning in the user manual for LCD TVs."If you constantly display still pictures, it can cause image burn-in on the LED screen and affect image quality"

        http://downloadcenter.samsung.com/content/EM/201609/20160926…

        But nah, you know better, it's unique to OLED, right?

        @KentT: LCD retaining images and OLED burning in are different though. LCD retaining images is from displaying still images for a long time whereas OLED burning in is pixels degrading. It doesn't matter how short you've displayed the images for if you do it often enough.

        You wouldn't be able to tell 2 years old LCD monitor apart from newer one other than from possibly less bright backlight (if it isn't broken that is), under normal usage situation. 2 years old AMOLED display would more than likely suffer from yellow tints (blue subpixels have shortest lifespan out of all subpixels) and possibly burn ins of items that were frequently displayed depending on how it was used. All those said, under same usage pattern, LCDs would fare much better in the long run.

        @Oversimplified:
        But it's highly predictable degradation. Keep track of how much each coloured sub-pixel has been used and you can compensate for uneven degradation using software. I know they do this on TVs, but it's more of an issue there since they're on so much longer, and are expected to last longer. Yes, that could effectively make the screen dimmer, but like you said, LCDs dim as well.

        A phone/tablet has pretty much a maximum usable life-span of 5 years - even if the software is kept up-to-date by the manufacturer, and even if the processor/ram/gpu combo didn't feel like molasses compared to a current model, the non-replaceable batteries will be fairly shot. 5 years is pretty much the max opverall so that's how long you need to keep the display decent.

        Also, even if OLEDs degrade worse than LCDS - after five years you may have had 3 years of superior picture, 2 years of comparable. That's still a win.

        @KentT: Not really? I do know Samsung does shift the pixels around on a lot of stuff that display static images (i.e. notification bar icons come to mind, AOD does something simliar), but that can only do so much. Most of the time, they still need to be at around certain area (notification bar at the top for example).

        I can't imagine Windows 10 being better than Android on this. Most programs have fixed UI elements (i.e. internet browsers, windows explorer, MS Office). Taskbar is fixed unless you change the settings. Plus, I'd assume Samsung wouldn't have been able to modify the OS as heavily as they do on other OSs.

        In my opinion, I think you are giving too much credit for the lifespan of the AMOLED screen. I personally think AMOLED screens have 1~2 years lifespan for normal users before the screen becomes noticibly yellow/end up with possible burn ins (less with more modern AMOLED screens, but still within that region). If the AMOLED screens has long life expectancy like you've mentioned, burn in issues shouldn't happen for most consumers. 5 years is looking at Galaxy S2/S3 era, if so, at least S6 or even S5 shouldn't have burn ins as it's only been 2, 3 years since release (Especially S6).

        All that said, in my opinion, you end up with colour distortion as screen becomes older on top of the possibility of burnt in images of certain UI elements. Software adjustments, unless you calibrate the screen individually, can't factor in the device's condition properly. I agree with AMOLED's advantages with colours, contrast etc etc, but its lifespan is downright horrendous compared to LCDs. Even worse, the degradation is not uniform and that cause more distinct aging of the screen (compared to just screen dimming). They've been improving it of course, but lifespan will never be its strong suit in my opinion.

    Can you provide a link about the amoled burn that related to this tablet?

      its not related to this particular tablet. its AMOLEDS in general. Most, if not all, samsung high end devices use AMOLED displays.

      My 2 cents considering moores law, by the time the screen 'burns out' on this, youll probably already be looking to replace it with a faster and an up to date one

        Thabk you for your reply.
        I like this tablet, and I think there is no serious problem with the amoled. I just asked as some people complain about the burning screen without giving a link or proof!
