notepro sleeps intermittently and then buttons are disabled - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

hi guys,
not sure if you're facing this issue.
i recently bought a protective cover, and after fixing it, noticed that the device is behaving odly.
it sleeps intermittently during use (as if you pressed the on/off button) and when you press on/off to turn it back, the home button and capacitive buttons are not functional. Back, home, and the task buttons can't work... after a few minutes of on/off, then it's ok.
however, when i take it out of the protective cover, it doesn't happen.
any of you have that problem?
Thanks.
Regards,
Liang

Yeah, I've experienced this problem too. I have a case that can flip the orientation of the screen. It seems that if I flip the tablet around the capacitive buttons come back. Very strange problem. I hope they can fix it in an update.

Hopefully the sensitivity of the magnetic sensor that controls smart cover functionality can be reduced via a software update. Until then being cognizant of it and realizing what orientation we have to keep our cover flaps away from to keep from triggering the screen off feature is all we can do.
Some cases have weaker magnets than others.

hi,
the cover i have does not have magnets.
where exactly the sensor that tirggers the sleep?
thanks.

The sensor is approximately 1.75 inches to the right of the G in the Samsung Logo and 1.5 inches from the top edge of the tablet.
Have you run a paper clip along all surfaces of the case/cover to determine for sure that there are no magnets embedded within either side of it? Magnets used for the on/off functionality in covers are thin and hidden inside the cardboard that is within the fabric/leather linings.

thanks... but what exactly am i looking at? or is it internal?
you reckon that it's the magnet that's causing this? funny, it was a cheap case, will run through a clip along the surface and check it out.
thanks

The sensor is internal. If you pass a magnet over that spot it will toggle the tablet screen on and off.

Placed a magnet under the mic/camera and the screen rotated.

I was wondering about the dock feature in other phones so I wondered if the dock had a magnet like the droid series phones. I placed a neodymium magnet and with the screen locked to portrait mode I moved the magnet around and in between the camera and speaker the screen auto rotated to portrait mode.
G2 still says it's not docked but I wonder if this could be something to look at for a car or home style dock.
Anyone else try this?
I placed a neodymium under my G2 when the screen was off and it turned the screen on
I think the phone uses a magnet to sense whether the keyboard is open or not. So its waking and rotating the screen b/c it thinks the keyboard is open, not b/c its going to dock mode.
If you hold a paperclip to the underside of the screen, the part that is exposed when the keyboard is open (but not exposed when keyboard closed), the paperclip will stick to the internal magnet.
I put an M5 magnet next to a powered down G2, and it got up, walked to the kitchen and made me a pastrami sammich.

Hammer meets nail. I tried the paperclip under the screen and found the magnet. 100% correct on your reply. Bummer on my half because I wish this had a docking feature.
Thanks for the answer!
when I stand my phone on the lower left corner of my laptop, my laptop goes into hibernation, and when i remove my phone, it wakes back up haha.

Don't buy ElecShield screen protectors

Don't buy these
http://www.amazon.co.uk/gp/product/B00A1V33J8
They break the proximity sensor (phone thinks it's near your head all the time). This is my experience, YMMV.
I guess you could cut a hole but it's bit of a PITA.
Mine are already on the way. What's the fit like excluding this problem?

They're a little on the small side but not too bad, I had mine fitted perfectly and it covers only the actual live area of the screen width wise, and is a little short of the top and bottom of the glass height wise, maybe 2 or 3mm.
I just did a little testing of the proximity sensor with my hand, without the protector on, and it seems that the proximity sensor only turns the screen off when the phone is vertical not when laying flat. Might test some more with the protector. I had to rip it off to end a call earlier!
Just done a bit more testing and indeed, hold the phone vertical while on a call and put the screen protector on, screen turns off, take it away, screen turns on. When the phone is flat the proximity sensor does nothing so if you put the phone flat while in a call you can access the keypad etc.

I spoke to an SGP UK agent on Tuesday. He said SGP are revising their design to allow for this. Said should have the new version sometime next week.
I have some cheap screen protectors that used to cover my SGS2 proximity sensors and had no problems, guess I'll report back when I get my phone ):
I have a BSE on order. I hope that doesn't do it :'(

If any protectors do cover it, a hole puncher should take care of it pretty easily. It may not result in the prettiest results, but it will get the job done until all of the manufacturers revise their designs to not cover it.
That works well enough for now

Poetic Slimline Case w/ Pics [First Impression]

I just got the Poetic Slimline in the mail yesterday and thought I'd post my first impressions
I ordered off of Amazon for ~$10 USD shipped.
http://www.amazon.com/Poetic-Slimli...Y0DO/ref=sr_1_1?ie=UTF8&qid=1368894249&sr=8-1
First off I think this is a VERY attractive case:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some features:
Magnetic Wake Sleep
Microfiber lined cover and back
Cut-outs for all buttons, ports, and S-Pen
Cover doubles as a stand
So the case isn't exactly packed with features like a hand strap or an extra pocket for memory cards or a larger pen, no cutout for the speaker on the front for international models but it is very thin, and that's exactly what I wanted.
The outside is a fake leather but it doesn't feel very cheap, we'll see how long it holds up though. One thing that is nice though is the tolerances are very good, and the cover fits very nicely with the snap on case. Another nice thing is that the magnet also holds the cover on the backside so it doesn't flop around with the case open.
I'll try and update later if I encounter any issues but so far I think it is a very attractive and slim case, especially for the price
Thanks for your review. I have the same case for my Int'l 3G+WiFi Note 8.0 and agree. It's a very nice case.
The three negatives for me are:
1. No opening or hole in the cover for the phone earpiece speaker.
2. The main microphone hole that is next to the S-pen silo on the 3G model is just barely covered by the plastic of the case. I took a small jeweler's file and filed it down so it no longer covers the microphone. It's only covered by about 1mm.
3. I'm going to remove the SLEEP/WAKE MAGNET in the cover to prevent a Digitizer Dead Zone on the screen! See the posts in this thread:
http://forum.xda-developers.com/showthread.php?t=2249587&page=3
I'll use an app that uses the proximity and/or light sensor to do Wake/Sleep functions.
Otherwise, I really like this case.

I'll be curious to hear what app you end up using for that. There are a few mentioned in the following post, but it sounds like one of them doesn't actually lock the tablet:

This device doesn't have a proximity sensor, so you will need to find an app for the light sensor. I haven't found them to work very well, but be sure to share your experience if you find a good one.

Interesting, the thread you linked only mentioned issues with the note ii but didn't go into detail. Is this permanent damage that occurs over time? Like will there be a problem even after I take off the case? Right now with the case on, I can use the S-Pen at every point on the screen, I checked using sketchbook there might be a 1 mm sliver on the side of the screen where the magnet is, but if that's all there is its not a deal breaker for me. However, if this becomes a permanent and/or larger "dead zone" I might consider another case.
EDIT:
My lovely artwork showing the dead zone

I can't speak with any certainty to the permanence question, but it seems like from your very helpful illustration that what you're seeing is the effect of the magnetic field along the middle of the right side, which does illustrate that having too strong of a magnet near the screen while trying to use it is problematic (which makes sense given that Wacom technology involves electromagnetic fields).
Per this post the location of the sensor for the wake/sleep magnet is towards the left. In theory, it should be fine to use a magnet there (assuming it isn't too strong) given that Samsung has build the device with a sensor for that purpose. But I'm just speculating.
I know im drawing away from the topic but assuming that the magnet does cause damage, would it still have the same effect if it were not on the screen? After much searching, I located that the magnet on my Moko shell is actually on the left bevel and doesn't even touch the screen itself..I'm hoping it doesn't effect my s-pen

That is a good point (regarding straying from the original topic): It seems like there is a lot of good and important discussion happening (and perhaps forthcoming) regarding magnet concerns (between the current thread and some other places linked above). Does it seem worth starting a separate thread (and linking there from here)? Just a thought (not a criticism or anything).

Does it hold well with the case open? Is there a lot of overlap/awkwardness holding it in your hand when it's open?
I just got the Note 8 hoping to use it both at home and at the office. Previously on my Tab I'd used a non-book TPU case at home (where I typically use my tablet most) and then swapped it out for a book-style case for work/travel. I'm hoping to find a case that might allow the best of both worlds and this one seems the thinnest/closest to that.

No there isn't much overlap with the cover open. It can wiggle up and down a little, but thats only if I move it intentionally. Generally it stays put

ну ты молодец, девочка, нашла куда написать)))
I'd forgotten about Poetic (have a couple of their cases for my Nexus 4 and iphone 5) and this looks about as nice if not nicer than the stock Samsung case/cover... and at $40 less! I initially bought a no-name "slimline" type case from Amazon (5 or 6 bucks) when I first got my GN8, but it was so crappy my N8 would actually fall out of it.... at the time there wasn't anything else but the generic folio type cases, which I hate. So I caved and got the $50 Sammy case, but now, I'm returning it to Bbuy and getting this Poetic if it comes in black!

Regarding the Poetic Slimline Case, Yes, I removed the magnet in the flip cover by using a sharp Xacto knife and cut a ~7mm "+" over the center of the magnet. I used a paper clip to find the exact position of the 5mm round magnet. I made my cut on the inside of the cover flap (microfiber side).
This part of the cover has a thin metal panel the full vertical length of the flap, so you don't have to worry about cutting through the front of the cover if you are careful. You can pry the little magnet off of the metal panel with the point of the Xacto knife. It is secured by a small amount of soft glue, like rubber contact cement.
After the magnet was removed, I lifted the microfiber cloth gently with the curved end of a paper clip and put a small dab of crazy glue on the metal panel in the center of the opening. Then just pressed the microfiber cloth down with my finger for a few seconds until it bonded and dried. I can barely tell that it was ever cut. Just don't use too much glue or it may absorb into the microfiber and create a hard spot that would scratch the screen. For that reason, it may be better to use rubber contact cement or another soft glue.
I did not remove the thin magnetic strip in the edge of the molded case that is next to the IR Blaster. It is far enough away from the screen to not affect it, and this magnet helps to keep the cover flap closed, though it is VERY weak and doesn't hold it very securely.
The folding cover flap also does not stay folded very well when you use it to prop up the tablet in either position. It will easily flop open unless you are very careful. The rubber feet on the edge of the Official Samsung Book Cover Case work well in this regard to keep the base of the tablet from sliding back as you press the touchscreen, at least on hard/smooth surfaces like a desk or table. However, they don't help much on any surface that rubber will not "stick" to.
I would actually rather have a kickstand case like the Case-Mate iPOP! for the i9100 Galaxy S II. It worked at just one angle, but worked in both horizontal (landscape) and vertical (portrait) positions.
And I don't really miss not having the automatic wake on/off function. It would be nice, but until there is more concrete evidence regarding the magnet affecting the digitizer, I'm going to play it safe. I purchased the 3G/phone version so it was quite a bit more of an investment compared to the WiFi only model. For now, I'm just pressing the power button on the side. It takes a very light press to activate. I haven't even bothered to install an app that uses the proximity sensor for this, like Screen Standby # Root.
Hope this helps.

No problem. So far the Official Samsung Book Cover Case is the slimmest and lightest of the cases that I've tried, besides a simple TPU case with no screen cover. Also, since it is the Official OEM Samsung case, they *should* provide warranty service for the Note 8.0 if the magnet does cause any problems with the screen.

I recommend you consider the STM Cape. It's really not bad at all in terms of extra bulk and it provides some nice protection (and there's no magnets!).

Nokia 5 flip case that works with hall sensor

The other thread seems be more about non-flip cases.
Has anybody succeeded in finding a flip case that uses the hall sensor. I am talking about cases that typically have a small round magnet somewhere that activate the hall sensor. This turns on and turns off the display automatically (on flip open/close).
I bought one off amazon: https://www.amazon.in/gp/product/B074M9RHZV/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
The case is OK. But, it does not trigger the hall sensor.
I tried taking a small magnet near the phone, around the bezel. No reaction from the phone. How is the hall sensor on this phone supposed to work ? Asus phones dont need any special activation for this. Samsung needed their special cover that has a chip (galaxy S5). Is something else needed to turn on the hall sensor ?
I emailed HMD global support and got the following link: https://www.nokia.com/en_in/phones/nokia-slim-flip-cover?selectedDevice=
A flip case is listed here for Nokia 5. Has anyone tried it/has any experience with this ?
Thanks.
Answering my own question. I could not find out an accessory that supports the hall sensor. But, did manage to find out where the hall sensor is!
The hall sensor is somewhere near the middle of the screen. On your lock screen, it is around the place that displaces the day of the week (Monday, etc). Strange place to have a hall sensor. But it works! Just try taking a magnet near this spot.
I guess, now I have to find a flat sticky magnet to stick on my flip cover
So, did you found some nice magnet? I have original Nokia slim flip case which doesnt have the magnet, i tried what you said and it works with normal magnet, but it it is too thick. It doesnt work with fridger stickers.
I also have slim neomdyum magnet, but i am affraid to try it.

I think the neomdymium magnet should be OK. I know that my previous asus's filp cover had a small (1/2 to 3/4 cm dia) neomdymium magnet. I would be more worried about the magnet hitting the screen when you close (not the power of the magnet itself). I also checked that a simple stick-on magnetic strip does _not_ work.
I made it work nicely! found a great thin magnet in notebook HDD, which o broke in half (about .2cm long and wide now) and then inserted it with ducktape in top of card pocket. Working flawlessly!
Edit: Just compass seems messed when magnet is near.
Ah, I was expecting it to be near the edge somewhere. I'll give this a go as I have a cheap flip case on mine. Does the magnet need to be quite strong? I have some sticky sheet magnets, so I'll maybe try one of them and see what happens.
Magnetic Tape - rather those which can be used to hang metallic tools on a wall than audiotape!! - works also perfectly: no worries about scratching the screen. Can easily be cut to proper size and maybe inserted seamlessly into any flip cover. Search for "magnetic tape roll"

Magnetic sensor for screen on/off - on the ‘wrong’ side?

Is it correct that the magnetic sensor (used for turning the screen on/off when closing a case lid) is on the left side of the U12+ - opposite to the side that every case you can buy closes on?
I have a couple of different cases for the U12+, both of which fold open to form a stand. However, I found that I can’t use them as a stand, because doing so puts the magnet in close proximity to the left side of the phone and turns my screen off every time. This also means that if I wanted to - no case I can find would be able able to turn the screen off when closing the lid.
Additionally, because both of the cases I have fold open from half way round the back, I tend to let the back portion of the case feed through my fingers when holding the phone in landscape mode (essentially, I use the case as a holding support). This method of holding a phone has never been a problem before, but with the U12+ - it means that the case lid is hanging down behind the left side of the phone and frequently turns the screen off when I don’t want it to.
Any feedback or thoughts would be welcomed.
Craig.
Can anybody confirm or refute my observations? I’d really like to figure out if I’m the only one who has experienced this. Thanks for your help.
This is correct. The magnetic sensor of the U12+ is situated on the bottom left corner, exactly where it was on the HTC 10 as well. You can also see its position on the HTC Diagnostics hidden menu, under the Hall Sensor test
Thank you
