Tab S2 9.7 power off after slight hit - Galaxy Tab S2 Q&A, Help & Troubleshooting

Hi,
I have a 5 days old Galaxy Tab S2 9.7 LTE (SM-T815) and was confused about some black screens on normal work with it. After some investigations I can reproduce this behavior:
After a slight hit on the back left side, the tablet is off (this means the display becomes black without warning, the power is down and I have to turn on / reboot the tablet).
I have made a short video of this behavior: https://youtu.be/dxm73Rhz3gM
Okay, there it looks like a little bit more than a slight hit, but it shuts down on lay it down on the table or release/connect the book cover on the back too. Seems to be an loose contact, I would say.
Well, is this a kown problem with the SM-T815?
Kind regards,
Purzel

HD7 build quality annoyances.

power button: Too recessed and flat, to the point where I now have to use my fingernail to power on the device.
volume button: Flimsy to the point where I can literally slide it up and down. I can also hear it jingle when the device vibrates.
Backcover Flimsy, moves around too much and is never tightly secured.
hardware: When I unplug my device from the charger and the screen is getting ready to time out, it flashes green, then times out... (this looks like it's going to create bigger issues down the road)
Power button: 1 in 20 HD7's I have exhibited the behavior you mention. It went away however. I would advise against using your fingernails if at all possible.
Volume Button: Again, 1 in 20 have this, and unfortunately it's the one I carry around. Two other HD7's I personally used did not have this.
I'd try to get it replaced if I were you.
I'm 2 for 2 on the first two annoyances (power and volume button).
I'm getting it replaced again (for the third time) tomorrow morning. I've also noticed these problems with the store models at various T-Mobile stores.
If I have the same problem with my third device, I'm returning it and getting my refund. Omnia 7, here I come.
Hmmm... I don't care much for the power button placement, but I haven't seen any of the other things you mentioned.

regarding issue #1, how did the problem go away? did some mechanism inside shift causing the power button to pop out more? just wondering?
i also have the loose battery cover. very annoying.
also about the screen... havent seen this mentioned before. i have a slight gap at the left and right edges of the screen where it meets the chrome-ish border. its pretty easy for particles to get stuck in there. compared to the hd2, this gap is pretty noticeable.
I thought I was the only one with these issues lol, figured the recessed power button was just a design oversight
@jimbonics: just wondering, but why do you advise against using your fingernail?

Seriously? I checked a batch of HD7 in malaysia, and exceptionally, all of them had this issue. You're just so lucky you dont have it

Maybe because of this ?
Thanks Shu and daaango.
I knew I wasn't crazy in thinking this was an issue only I was experiencing.
I've also read several phone reviews, and a lot of the reviewers mentioned about the power button being recessed and stating frustration waking up the device.
I don't know how HTC can fluff up something so important. I mean, what good is a product if you can't power it on; wake it up? One would think they would put emphasis on having a solid foundation on the power button.
Melcali: Yeah, on one phone the power button managed to become flushed, to the point the user had to use their fingernail (even though i found it easy to turn on with the flat of my finger, almost like it was capacitive). However, next day it had 'popped out' a bit and had become less recessed and hasn't been a problem for him since.
daango: In addition to what Shu posted, using your fingernail is likely going to cause you to press the button in harder than it needs to be, which would likely cause the button to be crammed in more and more over time. If it can't be prevented, it can't, I'm just advising against it.
I've got two unopened spares. I'm going to crack them open and see if the volume button jiggles.
Ah, thanks shu and jimbonics for explaining that
Honestly, I don't think it can be helped. Maybe my fingers are too round or something, but using my fingernail seems like the only option right now. I might try adding layers of tape on the button so its easier to press but idk yet... it might take away from the aesthetics

All five units I've come across so far -- my defective original (corrupted memory), my current one, a second defective one (also corrupted memory), its replacement, and an in-store demo phone -- have the same issues:
Recessed power button
Very difficult to press camera button (basically useless)
Loose volume rocker (the case opening is about 0.8 mm too long for the rocker, so it moves around)
Imperfect battery cover fit (the plastic cover flexes from the opening process, so usually doesn't fit perfectly)
Weak screen support in bottom-right (press a bit on the search key and you'll see waves on the LCD)
On the two that I've had long enough to use, the clear coat on the kickstand is flaking off, and the Windows Phone logo, which was barely visible to begin with, has almost completely faded away on one of them.
Kind of sad that HTC screwed up so badly given that the HD7 is a barely-modified HD2, which was among the best-built phones on the market.

wow, you have had a lot of problems. I'm still on my original hd7 since second week of november.
1. power button is slightly recessed, but no problems pushing it with my finger (not nail)
2. camera button does have some orange on it, but it functions properly.
3. volume buttons work fine, maybe a little slide to the rocker, but doesn't effect controls
4. no flaking of clearcoat, no wp7 logo coming off, no lcd discoloration no matter how hard I press on the search or back buttons.
5. Back cover fits properly. I haven't had much reason to pull it off after initial placement of sim card, thanks to phone not constantly freezing. There is a slight gap where the back cover meets the smaller cover.
What are you subjecting your phones to???
I agree the hd7 build quality might not be iphone, but it's holding up well for me. It's not like we have a lot of choices on t-mobile, the dvp has way more problems at this point.
amb9800 speaks the truth. I went through 3 different units that had defects to varying degrees. I had similar issues with the EVO as well. HTC are notorious for shoddy craftsmanship.
I have the same problems they started AFTER my 30 days .. So i havent tryed to go and change at my local T-Mobile!! Is there any loop in the contract or something that would let me change it for anither phone and pay difference/get a refund xD
have the same problems as the op

[Q] Known WP8 issues or hw defect? (ATIV S Neo)

Hi all. Got my first ATIV S Neo with Sprint a couple weeks ago, had graphical corruptions, and random reboots, replaced it for another.
This one works much better, but there are some issues I'm seeing (nitpicking?) and I'm not sure if I have another defective handset or if this is just WP8, or if this is common to just this handset. Came from an HTC arrive on WP7.5 and things were pretty stable.
1) Occasional live tile animation stuttering; If I, for instance, go into the messages hub, sometimes the live tile swing animation will lock for half a second and then immediately pop into the message hub. Happens loading other apps too.
2) Occasional lock screen weirdness;
2a) very rare; press power button, screen comes on, screen fades out like the phone lost power but not to backlight, then backlight shuts off, pressing the power button again, everything works fine.
2b) occasional; in a dark room, press the power button to wake to lock screen, press again to turn off. screen/backlight goes out, backlight comes back, then goes out, then quickly comes back and back out.
3) in IE, typing in the address bar, text input freezes as it brings up suggestions from bing. (type "google.com" and get "gole.com"). disabling search suggestions makes it go away.
4) Text notifications stop working; sometimes the text notification sound stops playing (vibrate remains working). Reboot corrects it. Have also had it where the vibrate alert goes away and not the sound.
Anyone else seeing these? Are these known or is this phone also messed up?
Haven't seen those on my (open-market GSM) ATIV S, but there were a handful of glitches when I first got the phone. Those were corrected in the first big fiormware update from Samsung in my case, but I had to wait a few months for it.

Thanks, that makes me feel a little more comfortable. These problems really don't feel like hardware to me, since they're fairly infrequent. I might have to stop by the sprint store and test the display model out a little.

[Q] S3 Mini Touchscreen Calibration

I have a weird problem with my S3 Mini. I replaced my broken screen with a samsung original replacement part - replacing run smoothly and I had no problems at all (wasn't my 1st phone and I have a lot of knowledge on electronics, even used esd mat and wrist band).
The new display itself is working fine but the digitizer gives me some troubles... if the phone is charging the screen is overall very responsive, you can tap on every corner and every tap is recognized but if the phone is on battery the phone reacts a lot different. Overall responsiveness is worse but working and recognizing every tap except in the right third off the screen. If you tap 5 times, only 3 taps are recognized.
I believe this "issue" can possibly resolved by software and/or calibration of the screen - do you have tipps?

S-Pen - Case Issue

Hello All,
I've recently acquired a case for my Note 8. I'm not much of a case fan but I figured I'll take the plunge as the phone is too precious. I got a normal (fake) leather book type case.
Thing is, every time the phone is in the case, it for some reason acts like the pen has been taken out. When I pop it in, the screen off memo appears (Despite S Pen being still inside) and the Air Command icon stays on screen (I've now disabled that in the settings). Yet whenever the phone is out of the case, I have no issues with the S Pen.
When I put the phone into the case, I insert the bottom half in first, when the phone is at a fairly acute angle of like 20 degrees, screen off memo appears and the phone thinks the S Pen has been engaged for the duration of the phone being the case. This also happens if I insert the phone top first as well. Yet when I lift the phone back out (This is when the screen off memo appears when I'm putting the phone in), the screen off memo screen just goes off like I just put the pen back in. When the phone is in the case, I can't use the screen off memo either. Quite frustrating.
Is the phone case itself to blame ?

I got rid of the cases with magnets. The fake ones are worse. Try using your SPEN and run lines across the screen in snote or any other writint app.

Question S Pen Inconsistency at S8 Ultra Edges - Normal?

I recently purchased a Tab S8 Ultra and it's been great so far. However, I noticed that the S Pen doesn't work consistently at the edges of the tablet, particularly the 'bottom' edge where the keyboard connector is.
I initially observed this when I tried to click the 'home' navigation button with the pen, but the click would not register. Repeated attempts to click were met with failed responses more often than registered clicks. This was with the tablet in landscape mode and the taskbar enabled - so the navigation buttons were concentrated at the bottom right of the screen. With the tablet rotated to portrait mode, however, the buttons were responsive and worked as expected. I tested this in Samsung Notes as well. It seems to be common for small 'dead spots' to appear when drawing along the edge. The thing is, when making a pass back towards those spots, they can sometimes be drawn over. These spots are generally in the same area, but the pens' ability to function over these regions seems random. See examples.
I assume this has to do with the magnets around the sides of the tablet interfering with the display/pen EMR technology, but it's odd that it is inconsistent. If the tablet is using permanent magnets at the bottom, one would expect the effects of their magnetic field to be present at all times. It would also be a pretty major design flaw if the pen doesn't consistently work with the navigation buttons in one of their default locations as well.
Has anyone noticed similar behavior with their S8 Ultra (or any S8 series tablet for that matter)? Do you think I have a defective unit?
Make sure you have not turned on disable gestures and buttons when using s pen. That will make so when you use s pen the home button and such won't take affect when touching them with the pen. So no it has nothing to do with magnets for keyboard. Since i tried now with my s pen and it's registering fine.
Hello
Im facing the same issue infact my s pen doesn't work properly in the middle of the screen also. If i press it too hard then it seems to work fine. It started happening a month ago can someone please suggest what i should do ?
Also if it take it to the service center will they replace the device ?

I have the exact same problem + it also happpes in the top edge not just the bottom ,,
As you said home button doesn't work with s pen but other buttons ( back , recent , screenshot , power off ) works instantly without any miss , which is weird
But in other scenarios , not home screen , like photopea.com ; the "adding layer" button ( which is at the bottom edge almost at the same place of home button ) doesn't work with s pen
Another example; in adobe lightroom the top edge have the same problem, it doesn't respond when tapping ir drawing on it , but it Does when starting the drawing in a closer area from the middle then moving the s pen to the edge , in this case it works , which is very weird

If your issues are to the right of the front-facing camera, maybe they have to do with the S Pen magnets?
I ultimately decided to exchange the tablet. My new one doesn't have any of my aforementioned problems. Also, the issues had nothing to do with the gestures option - the dead spots existed with gestures on/off.
Although the issue is solved, the root cause is still unknown. I'm starting to consider if the problems I had were due to a case. For a short period of time I had a Speck Balance Folio on my first Tab S8 Ultra. It was a nice case but I had to remove it after the first day because the cases magnets were creating huge dead spots on the screen. The case had a pretty large magnet spanning the lower half of the tablet, so maybe it was strong enough to permanently alter the in-built tablet magnets? I never drew on the edges of the screen until after I removed the case, so there was no way to know if the issue existed beforehand.
I currently have the official Samsung Protective Standing cover on my new tablet, and while it does have two small magnets near the edges, I have no issues using any part of the screen with the S Pen.
I guess to answer my own question in the post, and to possibly help anyone reading this in the future:
Your tablet should not be having issues near the edges of the screen.
Avoid all third party cases if possible, unless they are confirmed to be magnet-free (e.g. Supcase Unicorn Beetle and Poetic Turtleskin - It's a shame there are no magnet-free folio cases with decent protection).

The problem ( in lightroom ) happens in the left side of the cameras
I have the official Samsung bookcover keyboard , i removed it but the home button stil didn't respond , then i thought what will happen if i try from a different angle ? And that's what i did , i used the s pen as its top is heading to the cameras not to my side , and it worked ! Home button responded in every single try ,,,, then i placed back the kickstand piece of the bookcover and did the same with the s pen , and it also worked with no miss , so i think it's not the magnets' fault , it's something in the angle of the pen ,,,, note that i tried the normal way of using it ( when the top of the s pen is heading to me ) and rotate it many times and touch the home button , didn't work , so this probably confirms that it's a matter of angle detection not dead spots or magnet thing
Also , the top left edge responded when swiping down to bring the quick setting , so maybe lightroom app is programmed to not detect the edge's touch in order to prevent any accident touching when handing the device
So i guess there're no big concerns here , we can live with that
Generally speaking, Samsung tablets have always had issues with covers that use magnets to hold the flap closed against the screen as they are too strong for the inbuilt algorithms to compensate for. The Spen itself is nothing but a magnet whose movement is detected by these algorithms. The magnet flaps interfere with that.
I have had ZERO issues since I switched to a cover that uses an elastic band to hold the flap closed against the screen. It has magnets, sure, but they're tiny and only for the lock/unlock functionality, not to physically hold the flap against the screen.
Hope this helps!
