    Android tablet overheating & fire concern.

    Android tablet overheating & fire concern. I upload a photo. This happen when I plugged in the charger to keep using it because the battery was getting low. The screen got very hot. I have done this plenty of times before without issue. It could be on its last leg. After turning it off & plunging the charger in, the white oblong disappeared that is in the photo & its not longer hot. Should I do a factory restore once charged & trash it? Should I see if it gets hot, when using it without the charger?

    This is an old proscan tablet someone gave me.

    Hey man, This should probably be over in the Hardware - Drivers and Hardware - Windows 10 Forums Section.

    But anyway, the excess heat is probably being produced by the concurrent charge and use. As you noted charging it while it's off is fine. You were probably feeling combined heat from the CPU and voltage regulator for the battery.

    I did a factory restore on my old Galaxy S5 last week while it was charging. It got very hot. It seems the reset process uses a lot of juice so I'd keep an eye on it while you do it.

    It seemed OK afterwards though - both charging and use were at normal temps.

    Don't trash it - if you don't want it, sell it. Someone will want it - just be honest in the description.

    If you turn up your brightness. You can see the white oblong that appeared in the photo, while I was using it & charging it. This also when it got very hot as well. Previous times this never happened. Also, the white oblong went away after turn it off & leaving the charger in. It also cooled off.

    The white oblong is what really bugging me. That ls how my very old crt monitor quit & some of my old analog tvs did a similar thing. I think they all smoked a little. I just don't want the house to burn down.

    I just have to see how hot it gets without the battery & I hope it doesn't blow up. I have seen the news on how certain batteries have blown up.

    It could just be lcd burn, or there is a gap between the digitizer and the lcd which is causing a ghosting effect.

    What model is it specifically? Could be a problem with the hardware altogether.

    I'm not an engineer - I was just mentioning that I found running the factory reset (on a different Android device) uses a lot of power and it gets very hot. This is mentioned all over the Android forums as well.

    It was the Note 7 that was recalled and that was a manufacturing defect. Samsung Recalls Galaxy Note 7 Over Exploding, Burning Batteries : The Two-Way : NPR

    It isn't going to explode but you may not want to leave it unattended next to flammable materials.

    I would run the reset and watch it - it only takes 15 minutes or so. If it gets too hot just unplug it and turn it off.

    If you are really worried about the safety of the device and not confident just don't do it.

    Smash it with a hammer until all the memory cells are broken and chuck it in the trash.

    It could be heat related due to overheating components including the battery.

    There are several plastic optical elements behind the front LCD image part of the screen that are used to diffuse the light from the LED or (now rarely used) CCFL components to give evenly bright illumination across the screen. If these elements are distorted permanently by heat, they may give brighter or less bright patches. Conversely if the LED screen part at the front of the screen is damaged by pressure the damaged area may have dark marks or sub-pixel elements that do not turn on or off.
