My device is slightly bend. Nothing crucial and obvious, but can be observes while device lies display side on a flat surface.
Applying some force to bend it back in shape helps a bit.
After the Nexus 6p, this is my second device with weak structural integrity.
Does anyone observe similar behaviour?

Specifically, the spot is just left of mid-line and about a 1/3 of the way up from the bottom in portrait mode. If you have the wallpaper of the quill with the scribble (not the ink well), it is just to left of the quill tip. If I press on the corresponding spot on the back or flex the tablet from the sides a bit, a bright spot appears on lighter backgrounds (it doesn't show on dark backgrounds). A white background is back.
Ok, so everyone is going to say don't push or flex the tablet and I agree However, I bought the MoKo rotating case and when I snap it in firmly, this spot appears. I remove the tablet or loosen up the left side of the case, the spot disappears. The case appears to flex the tablet a bit, causing the display issue. I'm going to give another case a try, but MoKo is really the only rotating case, which I really liked.
Since the back of the tablet is "spongy" in this spot and allows it, I was trying to determine if this is a design issue with all of Note 8's or a manufacturing defect with mine. I went to a big box store to test, but they no longer have the Note 8's on display. However, all of the other Samsung tablet models have this issue in one spot or another. It seems Samsung has sacrificed sturdiness for a lower profile. So, I'm wondering if folks can help me determine if I should return this for another unit or deal with it.
I'd try flexing the cover's tabs some to see if I could alleviate the flexing... this is common on all tablets and phones since they are made to be as light as possible these days.
You might be able to heat the case holder with a hair dryer to make flexing/bending it easier.

I've seen this in mine. Definitely pressure flexing back plate pressure on the battery frame. The screws holding the battery will press from the back of the LCD and you'll see a bright dot. Relieve the flex/stress or the dot it permanently bruise.

DizzyDen,
Thanks for the suggestion. I did try flexing it back into shape, but to no avail.

dtvboy,
Thanks for confirming the issue. You are right, the spot does resemble the tip of a screw. I just received the fintie slim case and I no longer have the issue. I miss the rotating stand, but it's better than the distracting dot or damaging my tablet.
Chris
You could also try sanding the flat part of the rotating holder... anything to relieve the pressure it puts on the back of the Note... bending the corners forward on the holder might help as well.
I have a rooted 2013 N7 running 5.0.2 that I recently installed in the dash of my car. During normal (handheld) use my touch screen works OK though it does have some periodic difficulties as seems to be common with this unit. However, when I mount the tablet in my dash, the touch screen is almost completely unresponsive. The tablet is mounted behind my stereo trim bezel so that there is plastic trim piece in contact with the full perimeter of the front glass. I believe the trim piece does not overlap with the LCD screen. Even so, I am assuming this is screwing with the touch responsiveness. When there is a little pressure on the edges of the screen - most of touch is unresponsive. Has anyone run into this problem? Ideas, insight, links to other threads are very appreciated. Thank you.

In your case, there are 2 reasons I know of that interfere with the touch operation: (1) the grounding issue where without holding the tab in your hand would cause unresponsiveness. Easy to test: if you leave the tab on a flat surface without touching it, and it doesn't respond well to touches, you can try multi-fix hacks. It helped in my experience. The battery percentage also affects - the lower it goes, the less responsive it becomes.
If it does respond then (2) the problem is what you've already identified. Any pressure, however slight, on the tab or glass would distort responsiveness on some units. In my experience, something as innocuous as adjusting the angle at which the tab stands on a case makes a difference. Here, I've found no cures but to maintain it at an optimizing angle.
Thank you for the reply. I am not having the grounding issue so it must be pressure on the edges of the screen. I'm still searching for a fix to this without having to redesign my entire mount.

A small PSA for anyone having issues with the touchpanel on Redmi 5 Plus:
This isn't a bug (though some of you may already know this); it's related to copper oxides forming on the connector of the touchpanel. The fix is surprisingly easy - the most difficult part is popping off the metal back panel which is kept in place by little notches. A pry tool or the side of a pill blister pack can be used (or anything thin like a guitar pick). You need to eject the SIM tray, then start at either bottom corner and get something lodged between the trim (the usb port is a good place to start). Then gradually use something else to work your way up the sides of the device until it pops off. Do not use anything with too much surface hardness or you could damage the chassis materials.
The touchscreen connector is the one left of the fingerprint sensor and immediately above the battery. It's a wide rectangle and identical to one across from it on the right (the connector for the battery). You can either pop it off and reseat it back down (which is what I did) or clean the pins with some isopropyl (do NOT use water). You probably won't notice anything amiss with the pins; the oxides are largely invisible and will have built up as the copper pins oxidise with the air. Just re-seating the connector may disturb the surface oxides enough to fix the issue completely. It did for me but you're best cleaning it with a minute amount of isopropyl on a new toothbrush; allow it to evaporate and seat it back in place.
After doing this my Redmi 5 Plus behaves like it did brand new. No intermittent input freezes; no keyboard taps missed, no mis-registered swipes. It's back to normal. 24 hours and counting; the difference is unmistakable, night and day.
I did it man and at first i thought it improved the touch screen but after a while i noticed touch screen non responsiveness all over so i think this is merely a placebo effect.

Did you seat the connector fully down? Sometimes it appears like it's clicked into place but it hasn't.
The guy who posted the YouTube video for this said you need to clean the connector with alcohol (i.e isopropyl). I didn't, I think it's pot-luck that reseating the connector worked for me. Supposedly you do need to clean it. I'd suggest re-attempting with some isopropyl if you didn't already but I can say without a doubt it's worked for me. The screen is back to normal responsiveness here and it was a right pain the a- to use before. Not had even a hint of the old unresponsiveness; I can say with certainty it's not placebo now it's been 24 hours. I was getting tons of input freezes before; now not a single instance.
Hi, since I got up this morning the screen of my Note 10.1 has a white halo on it.
Do you think it's a hardware fault? New screens sadly cost double what a used note 10.1 would cost, but maybe its just a loose connector?
Its flickering and getting worse the more contrast it has to display.
Anyone have seen something like this before
That must be a mechanical defect. Probably someone sat or laid in the Note. One of the two glass plates or the rear polarizer have been bent in a concave ir convex shape.
Can also be caused by excessive heat, like on the small lcd in my car dashboard, where a similar phenomenon has started to occur more and more often and in a more severe manner recently, caused by sun exposure and the car's heater and disapperaing when cooling down.
Or delamination of the gapless touchscreen. Now there is a gap on the outsides.
Thx for the reply. I have the tablet hanging on the wall, using it as an interface for my home assistant, so the screen is on pretty much 24/7.
Therefore i can't really imagine that there was too much pressure on the screen at any time and heating up could've maybe happened if it locked up during the night, but that hasn't really happend ever and in the morining it was running just normal, except for the screen. The sun can't really get to it either.
Well good thing is the problem fixed itself. The affected area started getting smaller and smaller and the effect also lessend over time. About 2-3 days it took.
Maybe there was some moisture inside it or something idk
Something had snapped or bent from and then back into shape.
I'd suggest that it was heat related, bootlooping while charging,probably.
I could trace such with the history of my battery monitor app(complete with temps and for as long as i set the the range), but the course graph of the system battery monitor could have have provided hints, too. But that's long gone now.
My very first Android device was a tablet, that once too many went into a bootloop. During charging AND during the time of the exploding Galaxy Notes. The whole surface (metal and glass) had the same temperature, no more hotspots, and was almost too hot to touch(50c at least).
I'm not sure whether the screen was discolored, there was only the small boot logo on black, but i immediately threw the thing into the bin outside, display still glowing in the dark.
This is really dangerous when the device is connected to the mains and the surroundings not fire resistant.
In the meantime the battery of my P605 started to blow up.
Middle of backside and even touchscreen are bent outwards.
But the display is still fine, though this kind of malfunction could happen to me later.
Will get a replacement battery. The original one from 2013 still has more than 50% capacity, but is much thicker now...
Has anyone had this similar issue? Camera lens crack without any falls?
Factory defect or the case put stress on it... glass is neither solid nor liquid, it's an amorphous solid. The laws of hydrodynamics can apply to it meaning it can respond to stress in seemingly bizarre ways. A load applied to one area can manifest itself in a seemingly unrelated area.
Glazing is a strange art...
