[Q] does the magnet on the casing affect note 2 ?

i was trouble by this when i got my new casing for note 2 , at some point i cannot draw on the middle part on the right side with the S pen.
at first i thought the casing was too tight hence result "presure" on the phone so that i cannot draw on it ( i can draw on it using my finger), so i removed the case and everything is back to normal.
untill just now i finally realised it wasn't the casing , it was the magnet on the casing ( when i draw, i flip the cover to the back ). when the magnet get too close behind the screen, the S pen won't work on that area.
so here is my question. is it okay for the magnet to be so close to the phone , and will it affect the hard ware ( either S pen or the sensor in the screen ) ?
many thanks .

I have exactly the same experience. ...so now my phone is without a case. ..
Saving up to get the SGP case soon

I had a case on for one day with a magnet clip on the right side of the screen and I noticed that the s-pen didn't work properly around that area. I can write there but hovering doesn't work too good.
I removed the case and it's been off for maybe less than 20 hours... But I still experience the problem and it also seems that when I'm using the GPS it can't fix on my location. It just jumps around on the map closely to where I'm located. Tried the same thing on my Note 1 and it found my location with no problem.
I think somehow the magnet from the case has affected something internally. I hope this is not permanent...

Ans: It obviously does.

Hello alls! Any Note 2 owners here have the Flygrip installed? Curious if there's any magnetic parts in the grip which could distort the compass. Thanks for reading!

Hm... Now I'm not sure the Note 2 behaved like it did because of the magnet.. I've tried several Note 2's in store and hovering on the screen around the sides only work if you have the S-Pen real close to the screen. The GPS works fine now, I think perhaps it was some settings I played around with with how to find my location.

I think so

The s pen's sensor in ur note 2 is some kind of magnetic sensor.

I think it affects the s pen input, I have a mercury case with a magnet which is used to close the case, and now when I'm writing or drawing with the S pen, the input goes haywire at that area so sad seems permanent...

Do you mean that even without the case you still have problems?

[Q] Smart Cover Problem

I owned a smart cover for my galaxy note 8.0, it can work properly like sleep and wake.
But here's the problem come,
usually the cover is cover the front of the tablet, but when we use it, we will flip the cover to the back of tablet.
while the cover touched the back side of the tablet, it will also put it as sleep.
so, how to disable smart cover auto sleep?
i had tried the "Lock instantly with power key", but it required at least security of "pattern"
Any ideas?
Need help! THANK YOU!:good:

I guess something is wrong either with your cover or device - putting the cover on the back should never put the device to sleep.
I don't recall anybody reporting similar problems here, also the small sample we have at home (2 notes + 2 covers) behaves correctly.
The best thing (although it's probably easier said than done) would be to establish which one is malfunctioning and have it replaced if possible.
otoh I would also be interested in a way to disable the cover on/off function - mine is so sensitive, that even the slight move of the front part wakes the device, causing increased battery drain and making betterbatterystats readings useless.

It happens all the time to me. Put it nicely in the back. Not a single bit cover the front. Shake the device a little bit. The cover hits the back of the device, make some noise and screen turns off. Magic. As if the device can sense magnet even by its back. But when it sits really tightly that no space bw it and the case, problem solved by put on some sticky tape in the back.

Smart cover not smart at all T^T~ but original case without having that problem right?

Smart cover problem
Still looking for a way to disable the software that causes auto sleep/wake.
The problem with some covers is that they are not authentic from the manufacturers. The original Samsung case for Note 8/N5100 has the correct magnetic power in the case flap. The other covers have a magnet that is too strong so when the flap is in the back the magnet still effects.
I surgically cut the magnet out of the cheep cover and closed it back up. Disabled auto wake with the modification. I am guessing the same could be done with the original authentic Samsung case but it is hard to cut the little magnet out because its built in seamlessly so you cant see the exact location of the magnet.

[Q] Cover flipped backwards turns off screen!

I was experiencing random screen shutoffs after fitting my galaxy note 10.1 (2014) for a new case.
It took a while before I finally realized that the random shut offs were being triggered by the case, more specifically, when the edge of my case came in line with the edge of the tablet, which is an awesome feature when you have the cover covering the front of the unit.
But the problem is it manages to shut off screen regardless of which side of the unit the cover is on, as long as the edge of the cover is aligned with the units edge. This can be quite frustrating when trying to read while holding the tablet in certain orientations.
Questions: I was wondering if anyone else has experienced similar issues with their cases/covers (a little research seems to indicate this is not an isolated issue and many, if not all, cases/covers suffer from this issue).
1) If you have not, which cases/covers do you use? Do these cases resolve the issue by never aligning the cover to the same position when flipped backwards as when flipped forwards (i.e. skewed slightly short of the edge when in backwards position)?
2) If you have experienced this issue, how have you addressed it? Can you disable the magnetic sensor?
3) Would weakening the magnet in the case perhaps ensure that it was only sensed in the forward position?

yes i have the same problem. pick up A generic folio type case for my P600. Case looks and feels great. Auto wake works brilliantly when I open the cover, but there is the problem of The screen turning off when I flip the cover over to the back and the magnetic edges meet. Dunno how to fix this yet. Tried the magnetoff xposed module but that doesn't seem to work.

I got the Moko slim case and the same thing happens, what I did to circumvent the problem was to put my screen cleaning cloth between the case and the tablet. This prevents the magnet from locking the screen when completely folded backwards, the only thing is that this method will block the camera with the cloth. For me this is not a problem I don't see myself using the camera on my tablet when I can use my SGS3's camera, and this way I never forget my screen cleaning cloth .

I've read about this on other devices on various covers as well. they think it mah be due to the magnet not being properly shielded. dunno any fixes other than get another case.

I hade a cover for my old Ipad and it all so turn off the Ipad when I flipped over the cover.
It did turn out the problem was with the magnet and after getting a new one, the problem was solved.

My poetic slimline work perfectly no issues at all. Love the look and feel, I do want a carry slevee tho for more protection if I wanna bring it out of the house. Or even just to store in the house. But overall love this case.

Get a piece of sheet metal (strip out a cheapie magnetic whiteboard , a few dollars at a variety store) cut to just less than the back of the tablet screen.
Cover it with a thin plastic film (to safeguard from cutting yourself)
It will adhere to the back of the screen magnetically and flatten the magnet's field
Now you can use the device with the keyboard tucked away behind the screen. (you may have to leave a small air gap say 5mm to 10 mm)
This does not affect the normal screen-keyboard functions when used conventionally

Same problem with Galaxy Tab A (Nougat)
There is an option in the tab to turn it off, but regardless what you choose, the tablet still responds to the magnet. Very annoying when you lay down your tablet flat. For now i just put something between the cover and the back of the tablet, like a handkerchief. This works for me, but ofcourse it's not a solution just a workaround. I'm still trying to find a solution.

Did you find any way to turn off the magnetic lock and unlock function? When I backfold my cover (aftermarket), it automatically locks my tab. Which is very irritating. I have Samsung galaxy tab S5e

There wasn't a good search result on a way to disable it via software or hardware mod so I thought I would post the solution I just did on my daughter's new tablet folio.
She has an old S3 Tab so the options are quite limited so figured modification was the only way. I ended up removing 3 magnets until I figured out which one actually did the on/off Hall effect. The smart thing to do would have been to use a magnet to find where on the tablet the Hall effect sensor was first, then remove just that magnet. The other magnets are for holding the clasp in place when the folio is open or closed.
I just cut an X over the magnet location, removed it, then filled it back in with hot glue. On her tablet, the Hall sensor was on the top left (fat arrow). It's annoying to have to do this but there's no other way. I tried the metal plate trick but that looked pretty bad and didn't always work.
Hope that helps someone

Samsung Keyboard cover has no wake up /turn off function?

I have just received my preordered Tab S4 with keyboard cover, but when I close the keyboard cover it does not turn off the screen. Also when I manually turn off the screen, close the keyboard cover and then open it, it does not turn on the tablet. Is there any setting for this in Settings? Or is this feature not available anymore?
Thx.

Keyboard cover does not have magnetic attachment that enables the auto-unlock... At least, that is already a thing on Tab S3 so it is not a big surprise to me if they ommited the feature on S4 as well.

thank you, this means the keyboard cover is useless for me. I tried with magnet and it does have magnetic response on the keyboard cover edge and also on the tablet edge, so I don't understand why it's not shutting down the tablet screen.

Curious if the standard cover has that type of support then.

I would suspect that if the keyboard cover can't do it the regular one won't do it either. As long as you don't have the screen time out value too high on the tablet, I don't see what the problem is. Mine is set to 1 minute and that works just fine for me.

the problem is that I had previous tablet S3 with regular book cover and was used to grabbing my tablet and by opening the cover the screen woke up automatically. Now it stays dark and I have to either press the power button or double tap on the screen. That's not acceptable. And yes, I do understand that "screen on" function can be set let's say for 1 minute, but that's not the point. This is really deal breaker for me. I will go to Best Buy tomorrow and try the regular book cover.
I have also called the Samsung support today, boy, they are clueless. Their customer support with heavy Chinese accent didn't even know that this tablet is out for public, so I hanged up and called again, this second guy told that my table is probably not sitting properly in the keyboard cover and I need to go to nearest Samsung center and they will adjust the position I don't believe what I hear......

The keyboard cover does't wake it upon opening, but when you connect it to the keyboard it starts. When not using the keyboard you can double tap the screen to turn on (Like LG phones), works well, takes about one second.

It appears that Samsung put the magnet in the wrong place in the keyboard cover. If you do not mount the tablet in the cover so that you can move the tablet up and down in the case - against the keyboard - you will find that with the tablet slid about an inch up from center that the magnet kicks in and the screen turns off.
I have a plain book cover, from Amazon that I paid $9.90 for that works PERFECTLY! For the price I paid for the keyboard cover, it just HAS to be RETURNED! Hopefully, Samsung will get their manufacturing screw-up resolved.

Thanks Jeffrey, that's interesting find with the magnet position. That's probably why Samsung support over the phone told me to try to move the TAB in the cover up and down. Anyway, I have returned the keyboard cover already and also bought just plain book cover that works very well and has the "ON" and "OFF" function.

The normal book case works fine. It's just the keyboard case that doesn't work with the tablet's cover detection.
It was the same story on the Tab S3. This product is broken by design. Still, at least they didn't forget to leave a hole for the camera this time. The manual of the keyboard cover for the Tab S3 pictured a gap for the device's camera, but the accessory itself didn't have one. If you wanted to take a photo, you had to remove it from its protective case, which kind of defeats the purpose of a protective case.

It seems like the keyboard case for both the S3 and S4 were fairly rushed, honestly.

I am pretty sure this is not the case. True, the keyboard cover has magnets. If you move the tablet around, those magnets may trigger wake up function as you observed, but that's not their intended purpose. They are there to hold the keyboard cover closed when the tablet is inserted. And they align perfectly with another pair of magnets in the tablet (you can just slide something like fork along the edge of the tablet/case to see whey there are). If you move the table as you suggested so they work as wake up magnets, then the cover will not stay closed.
I believe the official book cover has another magnet that triggers wake up function. The keyboard cover does not do have wake up by design, maybe because they expect you to mostly use it in keyboard mode and as was said before, when you attach the keyboard, that will trigger wake up. I agree that it's kind of a silly decision. I would like to have wake up at least as an option. But it's not faulty manufacturing.

It unfortunately is not a feature. the only way the keyboard shuts off the screen is if you were using the keyboard and then disconnect the keyboard from the tablet

I tried putting a small neodymium magnet on the outside of the case and it seems to work. Meaning, all you need is a magnet in the right position. That position seems to be right above where the bottom right edge of the tablet would sit when you mount it to use the keyboard. If only i could x-ray this thing to see if there is any sensitive components behind the plastic in that area, I would drill it and embed my magnet there. Its plenty thick enough to flush mount the magnet there...

I think that's not the way the Keyboard Cover works.
The Keyboard Cover is only for people who always use it.
I own one, actually 2 as I also bought for my wife, and to automatically TURN ON your Tab is by connecting it to the keyboard.
And to automatically TURN OFF your Tab is by disconnecting it from the Keyboard.
That's my 2 cents...I hope it helps

I've had the Tab S4 since before the Android 9 update and had both the Samsung Keyboard case and the regular book case and both would wake and put the tablet to sleep when opening and closing it BEFORE the Android 9 update. After it only seems the book case will do the wake/sleep functions but not the keyboard case. I think it's just software and it's really frustrating because that update has been out for months and nothing's changed I still have to manually put the tablet to sleep after closing it which defeats the purpose of the magnets built into both devices (keyboard case and tablet).

Accessories Standing cover with Pen

Got my case today and it's OK, but a couple of gripes. There is zero protection for the hinge. Drop it on edge and no safety net. Given that's kind of the heaviest area when folded seems likely to be what hits the concrete on a drop.
The front cover seems to slide around a bit if you put edge pressure on it.
While wireless charging works with the stand slotted, the pen holder prevents it from getting close enough to charge.
Also a bit too bulky to feel natural in the hip pocket with the pen slotted in, though I expected that. The pen is for travel and meetings so I won't have it attached all the time.
The back of the case shows fingerprints almost as bad as the screens do.
*EDIT* And finally I just noticed - the stand is really only useful when folded and in landscape mode. Otherwise you might as well just lay the phone down it leans back so far.
The gray-green of the case is definitely the color I expected the phone to be, so it's not a match to the phone case gray color, but the phone color is only really visible around the power button.
Sorry for potato photos, the only thing I had handy to shoot with was my Surface Duo 1.0.

I was able to chose the color in the US.

One thing I do like about the pen attachment; when the pen is installed with the phone open and the power and volume buttons ot the top, I can slide the pen out a couple inches and with my left hand I can completely hold the open phone. The pen slides between my middle and pointer fingers and the phone balances while open and is weildable.
Maybe I should add a photo?
