Magnetic sensor experiment - Nexus 7 General

Hey Folks. Wanna take part in a little experiment?
I recently bought one of those leather cases which include a built-in magnet which wakes the N7 when it is opened, and puts it to sleep when the case is closed. Well, much to my disappointment, the wake/sleep feature only works intermittently with my N7 . However, it works perfectly with my wife's N7!
I found an app on the Play Store called Android Sensors which gives an interesting insight into the N7's sensors. Guess what? I discovered that the magnetic sensor on my N7 was apparently far less sensitive than my wife's N7. Mine detected the local magnetic field to be approximately 17 micro-Tesla, whereas my wife's detected it as approximately 50 micro-Tesla! Even more strangely, if I tipped my N7 upside down (screen facing the floor), it became far more sensitive, and remained so when returned to the usual orientation! I'm not making this up, I promise
If you want to repeat this experiment, please post your experiences here...

Mine reads at 79.

52 upright, 62 upside-down, 58 erect, 60 when rotated 270 degrees. This is a Nexus 7 purchased a few weeks before it officially hit retail, two weeks after announcement.

Just a thought with no idea of correctness...
Have you looked at a take apart for the Nexus? I ask because I wonder if the sensor itself isn't mounted on the mobo but is a wired in sensor and yours has become dislodged?

There is significant variation in the earth's magnetic field at its' surface. Since this is a worldwide forum, having folks randomly report values won't provide useful insight.
If you use Eclipsim's GPS Status & Toolbox app, it will report the total field strength next to a reference value computed from a geomagnetic model that uses the GPS fix.
In my case, it reports 43/47 uT (measured / computed). The measured value does not seem to change with orientation.
From eclipsim's website:
Magnetic field: the three values represent the strength of measured magnetic field / the calculated strength of the field / magnetic declination (the difference between true and magnetic north). (Tip: the first slash will turn into a question mark if the phone detects that you have to recalibrate the phone’s magnetometer.)

[Edit] PS I installed that Android Sensors app - it reported the same value (43uT) in three orthogonal orientations.
I would make sure the tablet is not near any ferrous materials (e.g. bolts or nails in wooden furniture)

Mine was all over the place ranging from 20-102 based on rotation. Then it settled down around 50. Funny thing is that even screwing with a magnet... it stayed around 50.
So I don't even think this is working.

Nexus 7 Screen turns off when pressure applied while holding

When holding the Nexus 7 (portrait mode) and applying slight pressure on each side, the screen turns off and only returns when I remove the pressure. Am I the only one experiencing this?
I've uploaded a quick video demonstrating this:
http://youtu.be/1bdlwpxTw7c
P.S. it's not the screen issue that everyone else is talking about, is it?
Take off the back and try reseating any loose cables.

What would be the best tool to open it with? I don't have a flat screwdriver thin enough to open it up.

The first time I opened my Nexus, I used an insurance card. The second and subsequent times, I actually used a NYC metrocard.

I reported this problem to Google and they sent me a replacement which worked perfectly - however when I put it in my wallet it had the same problem. The original Nexus also worked perfectly out of the wallet. I determined that the problem was the autosleep sensor which is triggered by the magnet in the wallet cover when it is closed. However if the wallet cover is opened and folded flat behind the Nexus the magnet is close to the sensor but at the back of the Nexus; since the magnet is still pretty close to the sensor it is triggered when the lower left of the screen is pressed (where the sensor is).
The solution for my wallet was to fold the cover into a triangle using the folds - this also makes the wallet easier to hold.
I still very occasionally get the problem when I move the magnet so I think that the sensor is a bit too sensitive.

You're exactly right!
I noticed just minutes ago the screen turning off immediately after I put down the device. It did this several times w/o a "problem", so I became worried and looked for the answer to this problem online. When I saw your post and read the word "magnet" a little light went on in my head -- I was placing the device on the loudspeaker! Apparently, the sensor in the back was picking the magnetism from within the loudspeaker enclosure (i.e. from the tweeter driver magnet)
Phew! First screen glass going loose, now this with screen going off -- I was getting real worried these Nexuses were cursed
Heh same thing started happening to me, thought the onboard graphics was faulty until I found this thread. Turns out it was the magnet on my case causing it, and getting a bit worn in that it's touching the back of my nexus now!
Same happens to me, I'm just about to exchange it, not sure if i should anymore.

Same happens to me this evening for the first time in 3 days
Happened when I got a new case, I just fold it so its not close to the sensor. I will exchanged my first nexus because of dead pixels and my new one does the same thing. I'm using the Hip street rotating case.

Galaxy Note II Case with Stand Photo Review

Hi initial photo review of this case. Will write a full review later tonight.
In a nutshell it is well made and light. Fits very well in trouser pocket. Does not feel bulky.
Price about £10.
You will find them on ebay in various colours.
If these photos help you decide. Feel free to hit the old Thanks button.
Glad to be of service.
That case looks great. I love how it protects the edged of the phone, unlike the official Samsung flip case. Does the flap stay closed using magnets?

Thanks for the pics. A link or two to the ebay sellers would be nice, though...
Edit: Is this the same seller?
Also, does the magnet cause any issues with the s-pen?
Tried one out and found that I had to take the back cover off to fit the phone snugly.
Since the cover doesn't have an NFC chip, you will lose that functionality. The case doesn't fit on the phone with the back cover on unless the one I saw was a duplicate. Moreover the magnetic closure is flimsy too.
Just my 2 cents.

The NFC antenna is embedded in the Note 2's back cover.
For the record. The handset clicked into case. Nothing had to be removed. Grips it fine. Must be a different case if you have to remove covers.
So far only really annoying thing is using it one handed. The folding cover is in the way of fingers.
There is a similar case that has a rotating cover. That would resolve this issue. Also enables a portrait stand.
Also as suspected. The home button is being pressed by the cover due to no recess (think thats the correct word) in the cover. This is activating the voice assistant. Disabled it as it is rubbish. But will mod cover at later date.

Another little update, these stand cases are really good for watching iplayer etc. But I think I am going to buy a leather sleeve/pouch type case. Ive always used them with htc handsets, due to most usage is one handed. And save the stand case for movie time.

The biggest flaw with the original Note 2 flip case is that the corners/edges are completely unprotected. If you drop the Note 2 and it lands on the corner it might shatter the whole screen.
Not enough protection for my taste...
I bought this case yesterday in a shop and was massively disappointed. If you fold the cover behind the phone to use it the phone is hard to handle and doesn't sit ergonomically in your hand.
BUT BIGGEST FLAW: The little magnet on the right side interferes with the wacom digitizer. Try pulling out the S Pen and draw a straight line along the right edge, and the line curves outward around the magnet.
I was about to return the phone when I realized the error was next to the magnet. Pulled it out of the case and problem gone. I could reproduce this problem anywhere on the screen by holding the magnet part next to it.
There are tons of reports if you google "wacom magnet s pen" about interference, so I would avoid using this case. There is apparently even a note about this in the manual somewhere.

This happens because wacom digitizers use magnets to work (partially, there's more to it) - the pen is a magnet. Crash course: A magnet creates a magnetic field around it. Whenever you're moving the pen, you're moving this field - any given point in space near the magnet experiences a change in this magnetic field (this creates an electric potential and a potential difference between points affected by the field). A really cool thing about moving magnets near wires is we create what's called an induced EMF - the change in magnetic fields causes electrons to move because of changes in relative potential difference between nearby points.
A static magnet (in relation to a point) will have a static field, but a field none the less - the magnet on the casing. When you bring two magnetic fields together, they interact to form a resultant field at any point in time.
The pen is still working as intended, but the other magnet has changed the potential you produce near that magnet via movements of the pen - thus, different and incorrect readings. It's relative to the position of the case magnet, so you get a different effect at different distances from the magnetic source.
The result is that the same motions of the pen near that magnet are causing different currents to be read than the wacom digitizer expects for that motion.
While it's great to hear through some empirical data that physics still works, I was already actively avoiding this case for this reason.
In contrast, previous smartphone cases with phones that use capacitive touch don't have as much an issue because it's basically a field of current that your touch (finger, capacitive stylus, etc) redirects some of that flow across. While a magnet could indeed affect this field, the magnet isn't moving so it's not as much an issue (it's still an issue because, depending on field strength, orientation, and relative locations, the electrons are still moving with respect to the magnet, and are repelled/attracted by the field in this manner to different degrees. However, the difference is constant and like is accounted for because digitizer system can't guarantee constant currents necessarily, so there is variation allowed for. With the Wacom pen magnet, it's weak enough to be noticeable.
TL;DR - Anyone with a course in EMF and an understanding of induction would be able to tell you this right off once they found out the pen uses a magnet. Incidentally, the magnet is also why you can do the hovering stuff so accurately. Other forms of non-touch gestures have many ways they could work too, but one way is your body affecting a field around the digitizer enough (whole hand swipe across without touching) that is is measurable.
It's also how inductive chargers (ones where you don't plug in the device) work. Changes in current flowing through wires creates a magnetic filed which, by orientating the wires, using loop/solenoid type configurations, this field changes (an AC signal). When your device is in the field, a similar configuration in the device is subjected to this changing field, and, more simply put, energy is exchanged via magnetic fields.
This is really cool because you've taken a changing current, which creates an electromagnetic field across other wires, which causes a flow of current.
Anyways, yeah avoid having magnets near devices depending upon EMF induction to work
In response. Regarding the case and holding it. I agree, does my head in sometimes. Hence why i may get a sleeve instead for when at work and use it one handedly most of the time. Regarding nfc, i aint convinced it would be affected until i get to test it. Regarding magnet, never noticed it until tested. Only effects 5mm of right side of screen and 15mm vertically, not the end of the world.
Just tested a piece of tin foil placed between handset and case at the point of the magnet. Didn't make any difference. Shame it cant be shielded.
Gotta say. The mobli is very well protected and the white case and mobile has yet to look dirty. Day job, hands get mucky.
Anyone got the case that the stand rotates? Does it make holding it less annoying?
Sent from my GT-N7100 using xda app-developers app
So, can the magnet cause any permanent damage to the gyroscope, compass and wacom bundle? I did notice that the compass is off by 10 degrees with the case on versus off.
I've used the phone for a few days without the case and it gets greasy too fast. So its back into the case again. It is pretty sturdy, just wonder if its possible to extract the magnet somehow! Maybe lodge a knife in there or something.
Anything that works by sensing the Earth's magnetic field, such as a compass, will be screwed up by a magnet in a case. It's really not worth buying a case that has a magnetic clasp...
I lodged a kitchen knife in between the magnet and the case and jerked around. It broke up into several pieces and came out attached to the knife. Since its either in my pocket or on a table the flap stays closed and no more magnetic issues.

On the SIII, the NFC -ANTENNA- is in the battery... The chip is on the phone motherboard. In the Note II, the antenna is in the back cover. Are you blind? Have you never taken your back cover off?
don't be so harsh.
some of us ex galaxy nexus owners had NFC built-in batteries..

3G Nexus 7 Not Fully Compatible with old Nexus 7 Cases

Well its seems Google were right, the 3G Nexus has a slight difference in that the Side Microphone has moved position due to the SIM Card Slot, so you can not use an existing Nexus case with the 3G Version if you still want to use the Mic for Google Voice etc.
Example Images Attached Below
Also top microphone moved to the side just above the power button, which is kinda annoying since none of my cases now fit.
Back to using a Jiffy bag as a case/sleeve

Cheers, Had not noticed the top one, too busy trying to mod my leather case for the side one, Rats!!!
Yeah I thought about modding the Asus travel cover but I don't think its worth the hassle lol, might just get another cheapy third party case and mod that to fit instead
But there shouldnt be any problems with cases liko moko, ivso slim cases/stands, right?

There might be some issues with other cases again because of the mic placement, but tbh it's not all that much of an of an issue unless you use the mics
If someone finds a case that has all ports exposed, please let us know.
To be totally honest, I am please they have redesigned the back of the Nexus 3G. Hopefully it will mean that the left screen left problems will be a thing of the past.
This case should still work fine:

And I highly recommend it. I've bought two (for me and family members) and it's rock solid. Plus, the seller is the best on Amazon.
drilling a hole in the proper place will solve all problems....
Quick compilation of possible differences between 3G and Wifi versions - if anyone with both models can confirm these, that'd be great!
1) Side mic placement : confirmed in first post
2) Top mic placement : confirmed by WarningHPB in second post. Do you have a picture of the top edge to show case manufacturers?
3) Headphone jack placement :
- Mentioned in this thread. However, I'm not able to spot a significant difference in location in available (but separate) pictures of the two versions:

Headphone jack seems unchanged, just put a tpu case on my 3g and it lines up. as mentioned, the two mics have moved significantly. I can say that the tpu case I have doesn't seem to adversely affect the microphones, every test I've run on my Nexus 7 worked just fine. Would still probably be worth drilling out the holes for the mics though.
Housing design changed in 3g? Screen lift on the left side removed ASUS?
Couldn't you just cut some holes in the appropriate places of your current case to remedy the problem? Like take a really hot pin and poke it through the areas where there were changed features?
Lots of Internal Board Changes,

Thanks for that. Very interesting. Sadly doesnt appear they have changed the way the left side is designed..unless the one they are comparing it to has also been redeisgned. So, its possible that the screen will still lift if that is right. But then they could have changed other things that are not visible from this.

The Wifi Version on the left of the image is a Launch Day device. So it is from very early in the production run I would imagine. Never had any problems with this particular one no screen lift etc.
The 3G One is also a Launch Day device for the 3G Model. (No Problems with that one either, no screen lift etc)
I just took Needle (for Sowing, not the ones crackhead use, although they would work)
Held it with some Pliers, Heated it up with a Lighter..
And Poked a hole...
Works Great, people in Hangout can hear me fine, Sounds as good as with no cover.

TF701 Build Quality Issues

I set up this thread to report and discuss build quality issues with the TF701.
Myself I already received a replacement because when docked the connection between tablet and dock was for a short moment gone when tilting the screen forward or backward to adjust the viewing angle.
You can see this for example when you have a sdcard in the dock and it comes with the message that it mounted the sdcard again.
This is my second TF701 and I didn't have any of other build quality issues.
The screen is flawless mounted on both.

Having the same problem going to try if they are going to replace it
Jsut received mine but don't have a dock so I can't comment on the dock issue. However upon opening the unit I noticed the glass was separating on the left and right side. I popped them back in. But I can tell its not as solid built as my tf700. I can stick a credit card between the glass and the back and could probably separate them if I tried. Im not sure if I received a defective unit but can you guys confirm what im seeing.

I went back to the store. They did agree disconnects are not normal.
In the store we tested two new tablets with dock and both had the same problem. If you move the screen the dock disconnect from the tablet.
Another this they refunded my money
So for me the TF701 is not the replacement for my old TF101
I hope anothers have more luck then me

Mine just arrived a couple of hours ago. The tablet is perfect.
The dock on the other hand has a couple of issues. The first, when I docked the tablet with it running the screen went black. Happened a couple of times. Then I remembered the teardown someone posted and I pressed firmly all around. Heard a couple of clicks like the plastic catches engaging. Since then no more issues docking and undocking. The other problem is it wobbles quite a bit in the dock, going to take a look at adjusting the clamping mechinism....
....Great, just happened again. Docking causes the screen to go black. Think this might be a bug. It only seems to happen if I have the charger plugged into to the dock when I attach the tablet to the dock. Another issue, the tablet fits so loosely in the dock it wobbles, there's like a 1/8 inch gap. When I pick up the docked tablet there's an icon at the top of the screen that shows the keyboard disconnecting and reconnecting. I'm going to send this back and take the hit with the 15% restocking fee. Argh....

I'm having the same problem with my dock, it disconnects every time you move the screen. My TF700 does not have this problem - the clamping mechanism comes up onto the screen quite a bit farther which keeps it from wobbling as much. This new dock is useless, gonna have to send it back which sucks because the dock is the reason I bought the tablet in the first place. I really like the Transformer design but Asus screwed up the TF700 with slow I/O and now they've screwed up the part they had right. aarrgggg!

Updated: . The clamp does not appear to be easily tightened, at least without risking breakage. I thought I might try applying some 20 mill (thick) electrical tape to the inside faces of the clamp to reduce the wobbling of the tablet when docked, It helped a lot, but when I paid close attention to the charging indicator and the mounting of the sd card, when docked, keyboard working then as soon as I touch the screen the keyboard disconnects and the sd card is unmounted, there was no change. I am done. Back it goes (dock). I must say I think the docking connector on the 700 is more robust. This is ridiculous to buy full retail and have these issues. (rant off)
***end update**
I agree this is a problem. Just got mine today. I am going to look at the hinge clamp, my clamp is rather loose and the hinge pins are tight. I think if the hinge pins were loosened a little it would move more easily and not flex as much at the connectors.
There was someone who adjusted theirs, I think it was for a 700.
I have a **theory**, actually a guess as to why the redesign of the hinge. I had returned my (new) tf700 because of a display issue where upon power-on, the screen would be all white. If the OS was running (sleeping) momentarily pressing the power button to sleep and repower would usually fix it without rebooting. But booting into recovery was a pain. If the screen was white you had to keep rebooting until the screen worked. I returned the tablet because a product should not be defective out of the box.
This problem happened two-thirds of the time when docked, about 1 in 8 when undocked. Opening the (docked) tablet with the firm hinge put pressure on part of the display, I think. So Asus redesigned the hinge.
I still liked the hinge clamp on the 700. Anyone got a broken 700 keyboard? I wonder if the hinge can be swapped and the new design charging connector moved to the old style hinge.?????

I was thinking the same thing, swapping out the new hinge with the old from my 700 dock. The other thing I was thinking is maybe the TF600 dock might work without mods. I'm going to stop by Best Buy this weekend and see if I can get them to take one out of the box and try it.
BTW After manually updating to the latest OS version I'm not seeing the disconnects nearly as often. There were dock firmware updates in V10.14.1.45 and V10.14.1.47. I'm guessing they increased the timouts before the keyboard disconnects.
Please keep us updated on what you find out. We live in a rural area, there is no "going to the store" option to test fit docks.
I'm returning my dock, however I'm thinking the replacement won't be much different. Possibly there are variations in thickness of the tablets depending on where they are made? My 700 had the glass face flush with, the top edge of the aluminum chassis, on my 701 the glass is raised about 1/16 inch (1.2 mm) from the aluminum.
It seems firmly attached but not as tight as on the 700.
In any event depending on what you find out I might look on eBay for a broken 700 dock for hinge oarts.
Its a shame such a nice design has these build issues ((

Did some research on the net. Doesn't look like the TF600 dock would work. The connectors don't line up. Oh well...

Upon further testing the disconnect problem between my tablet/dock appears to be a fault with the tablets new connector as well as well as the loose fit in the dock. When plugging the tablet into my computers USB port I get the same random disconnects, the slightest tap on the tablet connector causes it to disconnect from the computer. This is a consistently repeatable and obvious fault - been in the tech repair business for 40+ years, I know a faulty connector when I see one. I don't know if this is a design flaw in general or confined to my particular device. In any case, this puppy is going back. I'd be interested to hear if anyone else can reproduce my results, might help me decide whether to get an exchange or refund. Thanks.
I'll take your suggestion and check Friday

May I ask where did you get your tablet? US or WW?
Yea I'm afraid the dock/usb/power connector on the new 701 is not as stout as the one on the 700. Its a sign of the times, save a penny here and there. I would not be surprised if the poor fit on the dock is just flexing the connector inside the tablet also until it just fatigues to the point where it randomly loses connection.
I'm away until Friday night, I have been rather pre-occupied with the dock issue and put the tablet aside. I will test my USB then on the tablet, if it shows the same disconnects its a deal breaker for me. Pretty sad what 600.00 will not buy. Great design. S***itty production.

US version.
I contacted Amazon and they are overnighting a replacement, amazing since I live in "the middle of nowhere" Montana. I think I'll hold off sending in the dock until I get the new tab.
I agree, the new connector looks pretty flimsy. I only had the dock for an hour and the tab one day before the problems started. Also I confirmed that (very) slightly bending the USB/charging cable in the same manner as it would be flexed in the dock causes it to loose connection to the computer or charger - suggesting you are likely correct about the poor fit fatiguing the cheap connector or the connector inside the tab has little or no strain relief and quickly fails. If the replacement has the same defect I'm afraid I'll be done with Asus. For $600 there must be another Android tablet that works as well as my ancient Acer A-500 that my GF is still happily using.
Holy Cow Batman!

This can't be a coincidence. I'm in Montana, too. NW part.

Mine gets VERY bright if I turn outdoor mode on. Unfortunately auto brightness is a disaster, it changes brightness about every 2 seconds, looking at if for more than a couple of minutes gives you a headache. Hopefully the replacement unit that's on its way won't have the same problem. Mine gets a bit warm and totally screams compared to my TF700, but it hasn't actually worked long enough to heat it up much.

Yes when I was playing with my 701 I turned auto bright off. It kept dimming to the lowest level. I am sure its a software issue however I am not going to invest more time in the 701 until I can get the dock connector issue resolved (or not).

Power saving mode is on by default, go turn it off to remove random dimming

Tech21 Evo Frame Wallet + S6 Edge: MAGNETS = problem ?

Hello everyone,
I bought a very good case that protects the whole device nicely and it also protects it from drops (claimed from even 2 meters height). I'm overall pleased with the case but I'm concerned about 1 thing, magnets. This case shuts very tightly because it has 2 bars of magnets, 1 in the lid and one in the back of the case so they come in contact and shut the case tightly wrapping the whole phone. (I know this has been discussed already but this magnets seem stronger than the competition) As a result, when using this case the compass gets totally useless (magnetic sensor can't work, won't calibrate and always stays in maximum value). I also measured the magnetic fields with another device and yea, when I approach it close to either magnet bar it gets high too. I don't use the compass often but I'm concerned about permanent damage on the magnetic sensor or on anything else in future. since I'm planning to use this case forever.
Any idea? Thanks.
