I recently tried an app called "android sensor box". All sensors seem to work fine except the magnetic sensor. It seems to detect strong magnetic forces somewhere. However, when I use my N1 phone and turn on the sensor, the sensor in N1 does not detect anything. Is that something wrong with Nexus 7 magnetic sensor? Anybody have the same issue?
Is that in the developer section? Oh, and did you check to make sure Magneto isn't hiding in the closet? (There's a pun in there)

I am not developing this app. I just want to check if the sensors in my Nexus 7 function properly.
There is no Magneto close to my room. The odd thing is the sensor in my phone does not pick up any magnetic forces when I compare both devices side by side. I thought about the N7 case may cause such interference but then when I remove the N7 from the case, it still behaves the same. Also, I installed a compass app to both devices. It appears to me that the one in N7 does not function properly, pointing to the wrong direction, even after I did the calibration as suggested by the app.
I have a Nexus 7 3g which I recently got it from Canada and ordered a flip case which had the auto sleep/wake function. However the auto sleep isn't working with the flip case. Can anyone please tell me, if the Nexus 7 3g has the capability of the auto sleep/wake function?? If yes how can I check that on the Nexus 7 or on the flip case (incase the flip case isn't working as it is supposed to). Any help would be much appreciated
Thanks
Yes it does, you should be able to do it with a magnet not sure where the sensor is though

its going to be hard to test the auto sleep/on function without another case or so.
they work by using magnets and well, i wouldnt really put a magnet near the device...
but yes, the N7 does have the auto function, so if i had to guess which one isnt working i would say that your case might be defective
Hi All,
I have recently backed this kickstarter project: http://www.kickstarter.com/projects...le-worlds-most-versatile-stands/?ref=kicktraq
It seems awesome and exactly what I am looking for but I am now concerned about the neodymium magnet attached to the back of my N7. I searched the internet and XDA but although I found concerns I found no valid conclusions about if a magnet like this attached to my device, not on a case, would cause any issues.
I see some people made some mounts that involved neodymium magnets, but it seemed like the device was connected to the magnets for short periods off times (car mounts) not long term/24-7/permanently like with this stand that seems so awesome to me!
Why no responses??
Any idea why there have been no responses? I would have posted this in the accessories section, but when I indicated it was a question I was told to post it here in Q&A.
I have seen that a few years ago people posted neodymium magnets would not be safe to tablets, but I wonder if that is still the case. Is there potential for screen damage? data storage damage? GPS interference? by having the magnet attached to the tablet, instead of on a case.
Does this also mean, that if I do get this product and the magnet is attached to me tablet, I can't have the tablet near my laptop (which has a regular hard drive or credit cards?
Thanks!
me personally, i would never have any magnets anywhere near my electronics no matter who or what says.
but the project and its devs seem safe as indicated on their page. just keep in mind it's your risk
Those magnets shouldn't harm anything. The only issue I can think of would be accidentally locking the device with the magnet.

ok stupid question from a stupid person....if the magnet accidentally locked the device how would I be able to unlock it?

By pressing the power button just like how you would normally wake the device. Or by moving the tablet away from the magnet should automatically wake it.

Got it!! I thought so...but just needed to verify!
Hopefully with the magnet being attached to the tablet it won't cause any issues. With the bigger/stronger magnet on the stand and the smaller magnet being on the back of the tablet I should have no issues with just separating the two!!
THANKS FOR YOUR HELP!!!
Can't wait for my stand!!!!!
Hi,
i own my nexus for one week, and today i used a smart cover which caused some troubles.
first all worked like a charm, close the flap, display off, open it, display on. magnets, how do they work? ****ing magic! :laugh:
well, a couple hours later the touchscreen wasnt responding after shutting down the display. at first, after opening and closing the flap a few times the touchscreen worked again, but by now its totaly ****ed. if the display shuts down, all i can do is pressing the power button for a couple seconds and then start again. (it has nothing todo with the smart cover, i think it was just a coincident)
heres what i have done so far:
- factory reset
- flashed the stock rom (i only unlocked the device)
- re locked the bootloader (mainly because im pretty sure its a hardware issue and i wanna return it...)
is there anything else i can do? i know that there are many issues with the touchscreen, but from what i read, its about ghosting and other glitches, not a complete breakdown that can only be fixed by rebooting and occurs as soon as the display shuts down.
thanks for your help!
What brand of smart cover/case are you using? and do you still have the same problems even without the cover?

yeah, the problems are even without the cover. i thought there was maybe a problem that the hall sensor got magnetized or whatever, but that doesnt fit with the symptoms.
i use this case:

Yeah seems that it's more of a hardware issue that was probably caused from the case if anything. Good thing you already re-locked the bootloader since I'd suggest returning it for a replacement. Just don't mention anything about using a case . If you do get a replacement, maybe try a different case to avoid the same problem.
Is using a case with a magnetic cover against tos?

No, otherwise why would they have put the sensor in the device to react to it?
I bought the official flip case. It has a magnet in the front. Unfortunately Moto have used a rather powerful neodinium magnet. So, your phones magnetometer will follow the edge of the case around rather than true north!!!! This doesn't matter for gps navigation, but for on foot travel, and any augmented reality apps that use the compass this case will make the behave oddly.
I don't know what the long term effect on the phones compass will be, but I don't expect it to be good.
In addition, but for me I think it is a small risk, this magnet will be capable of damaging some computer storage mediums and possibly, wiping swipe card data...
I have no idea why they chose to use such an aggressive magnet. I can hang the phone from a metal bar with it, no problem.
Just thought I would share....

Good to know, i had my worries about this as well. Putting a magnet over the phone 24/7 didn't seem like a good idea

Yes sir, you should that. It is ridiculous to make such design mistake on an official case. I was about to buy one but after reading your story I am not sure anymore. Keep us posted.
Btw; you can contact Motorola via their official app Moto Care.
Glad to know, that I am not the only one who is concerned about that magnet. By the way there are two magnets. A weak one to trigger the screen on/off and a strong magnet to keep the case closed.
After removing the strong magnet you will be able to use the compass with the cover flipped to the backside.

Edit: The strong magnet was on the lower third, where the cut is visible.

TIL that official Moto accessory screws up Moto phone. But look at the good side: you can now keep it on your fridge door!

spoke to moto care. sent them screen shots of the magnetometer all messed up. They said they will get back to me, but no one else has reported issues... *cough* bull**** *cough...
I have noticed today that even when I remove the case, the magnetic sensor is all messed up. It seems after a week of use it has screwed up the sensors calibration (probably correctable)..
evidently, part of the cheap price is a lack of proper beta testing of the phone and accessories....
I have ordered one from amazon. Now I will sent it back. I have my concerns too so I wont even try it.

With GPS Status from Play Store you can force recalibration.
.
I can also confirm this. I have a white flip case but stopped using it after a week as it got in the way. I just put it back on and sure enough my compass was exhibiting the same issue. How did they miss this?

Recalibrating the compass with the GPS toolbox app seemed to have fix this issue for me

there is a small metal square on the inside of the flip cases backcase. I 'think' this is intended to shield the sensor from the magnet when the case is open. It clearly is TOTALLY inadequate to the task. I'm speculating this is what the metal square is for, as it corresponds in position exactly with one of the magnets in the case door, and this metal square is not present on the normal back case..
Simply lazy design and testing... why does it even need a magnet to stay closed :/ its like closing a book with a magnet lol, they get along fine without them!!!!

Thank you for contacting Motorola.
We regret that there is no possible solution. Compasses operate by magnetic field, and any interference with any compass magnet. There is no way around this.
If you are using a Motorola original case, rest assured that will not hurt your terminal. Imam to close the lid affects the compass but not strong enough to damage the terminal or delete any internal memory power. We apologize for the inconvenience.

I don't understand, are you saying you work for motorola? was this a response you got from motorola??
Motorola cannot release an OFFICIAL ACCESSORY!! at a premium price (£20) that causes issues for the core functionality of the device. I will press the issue with motorola until they acknowledge their mistake and resolve to provide me with a refund, equivalent compensation or a replacement back cover that doesn't cause these problems.
Imagine if you bought a New car; You bought official seat covers for your car that the manufacturer heavily marketed to you, but they make the satnav useless. Do you think any car manufacturer would ever get away with this??

As long as the flip shell is folded completely over (so it is flush with the back) my wife's compass works flawlessly. It's actually better than my n4. As I only have one sample to go off of I'm not saying this issue is being over hyped but it isn't always an issue

I've tried it this way. If you fold it completely flat, and line it up to the millemeter, the compass works about 50% well. It generally adjusts to north, but it flicks back and forth between north and where the magnet is on the case. You can also see the gauss meter jumping around a lot.
I suspect the magnetic power of the magnets in the case vary a large amount they wont be very expensive ones after all..
