Hey there,
I got one of those "smart" cases which send my Nexus 10 to sleep and wake it up once i close/open the front cover.
However i wondered how this really works, is there a sensor within the Nexus 10?
Also , i lately put my Nexus 10 the wrong way round(with the screen still facing me but the lower bottom, where the pogo connector is being up and the camera being down) in the case and closed the front. As expected the Screen didnt shut nor did it wake up when i opened it.
So i guess there is no sensor on that side of the tablet?Is it possible then to harm the hardware inside by the magnet withing the case. I mean when i put it in the wrong way round.
Thanks in advance for your help!

LOL. There is no wrong way! OK. There is. Don't drop it on a hard surface.
There are magnets in your case that trigger the wake up/down of your N10.
the magnetic sensor is right about the left side of the ambient light sensor... try running a fridge magnet there and see the screen go off and on when the magnet is away...

Hi All,
I have updated to the latest AKU3 ROMs and also a few months ago I replaced the housing...However, I've noticed that the screen does not automatically rotate when the screen is swivelled??
Now is this because I did something during re-assembly of the housing OR is there something in the ROM's that disables the hardware somehow??
Cheers
ODY
Unlikely to be the rom, since it's part of the system HTC provided.
If it's been disassembled it's more likely that.

hey VJ, sorry to bother but do you know what jumper/cable/connector/switch to jump/disconnect/tape inside the Universal to keep it from switching?
I'm sure I saw someone mention that the screen rotation is done by a magnet and switch? It's possible that maybe a small magnet fell out during disassembly? But I have looked throught the Universal repair manual and I can't find any reference to such a magnet??
I'd be nice to know exactly where it is so one would be able to take it out, if it were easy. I don't know if I wanna disasemble mine yet...
EDIT found it!! If you use a very, very light metal chain, as I did, with a keyring @ end, you can hover it around the Universal and see the tension of the chain when it's near the magnet. the keyring sticks too!
it's on the lid, behind the video-call video camera. I'm going to check the lid part of the manual.
Well taking the screen section apart is easy! You don't have to disassemble the whole unit. Looks like my magnet fell out then! Trouble is I want to sell mine so I'll just have to declare the auto screen rotate doesn't work (I've made sure that there is the rotate screen icon on the task bar though!!)

it works!! I tested it with the very small and highly magnetic point in the bezel of my tablet PC (to hold the pen) and it did change orientation.
thing is that it seems to be stuck beside the sound-holes (when the unit is closed).
I wonder how could I disassemble the lid only? are none of those screws @ the bottom connected to the back part of the lid? if so, that would be awesome!
Hi, on the xda's ftp, you'll find the maintenance manual for Universal...may help you to disassemble yours
thanx for the link!
however, it seems rather risky to try to pry the bezel open while still on the unit. Anyways I'm doing it right know. I'll get back to you.
I did pry it out and took the magnet off... painless(*) procedure and flea-sized magnet! don't loose!
I took a couple of pictures detailing the magnet position and the lid disassembled while still on the unit.
if you want to do this procedure do not loose the tiny screws and...
(*) be careful with the outer speaker (the one that lets you hear a call while the screen is facing the keyboard when closed), it isn't hard wired, it's just two small and fine contacts that might get distorted when putting the lid cover back... I had to take mine out again to correct this problem.
also, be careful with the screw driver and digitizer, as you'll be working in very akward positions to avoid disassembling the whole unit, and take off the battery of course.
Thanks for the photos - looks like my magnet feel out so I bought some 1/8 inch square magnets from ebay. It took a couple to find the sweet spot where the screen rotated but at least it works fibe now!

no problem. I'm also going to put the magnet back, now the unit doesn't now when it's closed, and therefore the outer speaker does not work. the screen also does not turn off when closed, only when the system timer tells it too... oh well.
you can turn the screen off by pressing the power button briefly.
no ext speaker though! maybe there's a way in software to disable just the rotation; i think the guys trying to get linux comfortable on the universal have some experience with it, maybe they can help.
Hi all! Im in love with this community from day 1
its my 1st thread though seeking for help/advice/your superior knowledge
Thing is that i want to mount my phone in my car using a small magnet attached somewhere at the dashboard and stick my HD2s back cover which is metallic...
my question is: is it possible because of the nature of the magnet to cause problems in the phones operation?? like radio interference or something like this?
looking forward to your answers
i think a magnet may interfere with the touch screen. not positive on this but am sure i`v read somewhere about tiny magnets being in the tip of some capacitive screen stylus`s. a stronger magnet to hold a hd2 would surely result in some type of touch screen interference. but like i said am not a 100% certain.

magnetism will not affect a capacitive touch screen. It will however mess about with the compass!
A capacitive Touchscreen works like a capacitor, whichs field is "spread" over the surface of the screen. By tapping you will change the the resistance of the oscilating resonant circuit, which has a specific resistance (which is related to the dielectric medium, which is changed by your finger)
With this, the phone is able to locate your finger in X + Y axis to find out where you have tapped.

Yes, obviously it will but thats the least of my worries as it wont be permanently attached to the magnet and the times it will, i wont be needing the compass app.
so if thats the only problem i think im gonna give a try to this project...

Does this mean that a magnet at the back could interfere with the circuit of the screen? and if yes i guess is temporary right?
waiting for more thoughts/input on the subject

this is school knowledge...
after some trial and error i found out that the back cover of HD2 although it looks metallic apparently its not coz it can't be attached to a magnet...
That would only mean that it is not made of an iron compound

I think it is made from stailess steel.magnets do not work on S/S.

Is that true? I know old compasses relied on a magnetised needle to work, but I thought the compass in the HD2 got it's direction from the GPS and the accelerator software??? How would a magnet affect these?

no it's a dedicated compass hardware
Actually, even my notebook apparently hurts it! Looses calibration
yes several times when i opened the compass application arround various interferences it asked me to move it in the usual 8-like movement to calibrate itself..
what about the rest of the phone and memory and SD card wouldnt it affect the storage ? i clecned out my speakerphone with a very small magnet yesterday to get all the lil pieces stuck on it.
and after that my phone(touch pro2) completely froze up and kept freezing up after first input untill i did a hard reset.

i did another little test with a small round magnet around 2cm diameter. i moved it around the back of the phone while looking at the screen and i didnt notice any interference to the screen, at least to my eyes it looked like the magnet did not interfere with the phone at all.
However i moved the magnet to the screen and tried to touch the screen gently with the edge of the magnet and the screen responded immediately and it looked very precise too! i did several presses to the screen with the magnet and in all of them the screen responded exactly as it should, just like it should with the press of a finger, i even wrote some letters as text and it worked great. so i guess thats how they make capacitive stylus..
next time im gonna try to draw on notes application and see how precise it is on that.. (as long as i find a smaller magnet that i can handle better than this one)
i might try to make my own capacitive stylus....
why not....
I have attatched a magnet to the back of my HD2 so i can use my vent mount, i havent noticed any adverse effects.
Hi! I am trying to find premium s-view case since the original does not stay closed but i wonder how hall sensor works and will it work with other than Samsung original cases. I am thinking about this case http://www.ebay.co.uk/itm/Tridea-Samsung-Galaxy-S4-100-Italian-Standing-View-Cover-S-View-Case-BLUE-/221221049258?pt=UK_MobilePhones_MobilePhonesCasesPouches&hash=item3381cd53aa ! What do you think and can you recommend other high quality s-view cases? Regards, Stepanooo
I bought a Baseus flip case for $10 and cut a window out for the S-View. Works a treat (i.e., sleeps and wakes phone, displays proper notifications etc). Nice blue case too.

Thanks for reply! Just can t understand how that hall sensor works, because if i cover sensor with hand or try to imitate cover nothing happens... read that it detects magnetic field but then i wonder if something should be built in the case itself... If someone knows please reply... Thanks

There has to be a small magnet in the cover for it to work. If the magnet is close to the Hall sensor on the phone, it will switch to the s-view mode.
You can try it yourself by moving a magnet along the left side of the phone until you find the right spot...

Unfortunately i don t have magnet with me now but thanks for approving the idea... I just don t understand why noone explains this quite interesting s4 feature... Searched google, forums, youtube - nothing...
So I've browsed around and there are plenty of screen issues, but I haven't seen the one I'm experiencing nor have I seen a solution. When I press the power button my screen comes on and turns off right away. Sometimes a few seconds after I hit the power button sometimes even longer. Most times I won't even be able to put in my security pin to unlock the phone. I see people saying Verizon will do an update soon but that isn't good enough considering I can't use the phone. I did find a loop hole to this problem. Quick start the camera with the volume down button then press the home button after the camera loads and it won't shut off by itself. I thought I'd post this method up for others having this frustration.
If this particular problem has been discussed and beaten to death then the mods can close the thread.
I've got a YouTube link but I don't have 10 posts to show you. Search for user name "vfreeza" and it is the only video I've uploaded. You'll see my first time turning the screen on was using the quick camera method and the times after is with just the power button. The screen turns off without even my hand touching the phone.
don't cover the sensor on the upper left hand side
Yup I read that too. My fingers rest at the corners of the phone and I've tried the not cover sensor thing as well, makes no difference.
Wish I could disable the sensor. I hate this problem

Just a quick update. I bought a Diztronic tpu case and the moment I put it on all the problems went away. Screen acted nornal and knock works. My guess is without the case my hand is making some kind of connection it shouldn't be when I'm holding it without a case.

Did your old case hug the bezels tight? because it tends to mess with the digitizer perhaps the incipio feather case? or a plastic case of some sort? just curious im pretty sure that was your problem cause if you barely press on the screen youll notice waves in the lcd screen and since the bezels are so small on this device some cases can do that.

Thanks! This case is never coming off! haha
My phone has that very problem and it's driving me insane.. i love this phone, but it truly is a hassel to use it after its been idle for awhile.. or at night... hands no where near the sensor or anything, it could be laying straight up or down n itll still have that problem.. thanks for reading.
I normally just wipe the sensor area, n it magically starts working again.. n i don't touch it, n the problem comes back after awhile....
Also naked phone besides screen protector, but it's not covering up the sensor.
My phone does the same thing. It's so ****ing annoying.
and Knock-On won't work.
Fell from about 4 feet onto a rubbery floor (gym service) while working out. Have an incipio feather light case on it and there now seems to be a small dent above the ear speaker. No idea why knock-on stopped, knock-off is fine everything else seems normal

You probably broke your proximity sensor. If that's covered knock on won't work to avoid starting the phone in your pants.

That is what i first thought because initially after the drop the screen would turn off right after being turned on. After a few restarts that seemed to have gone away but still no knock-on. I downloaded an app call "Phone Tester" and the proximity sensor comes up as "near"
Neare means blocked
its possible that your connector is just disconnected. if you can open up the battery cover and the rear cover its quite easy to find the connector just give it a press and see if it works. tip for opening the battery cover - pull the micro usb side!!

Got it (you'd think they could just say blocked).
So I kind of smacked it around, cleaned it off etc etc and it says "Far" now. Knock-On is sporadically working.
I may try and take apart the back cover and poke around
