[Q] Any problem with nexus + case magnet? - Nexus S Q&A, Help & Troubleshooting

Hello,
I got a case for my Nexus S with magnet (the only I found in my city) and I'd like to ask if there is going to be any malfunction with the screen or any of the sensors of the phone because of the magnet that the case has.
I downloaded the "Phone tester" app that tests the phone's sensors and I saw that the values of compass and magnetic field were tottaly different when I put the case close to the phone. Of course this is logical because of the magnet but I'd like to ask if there is a chance of damaging anything in the phone after long term use.
Thanks

long term damage, probably not. throwing some of the sensors off, most likely. i had a case with a magnetic snap for my g1 back in october 2008, and i noticed that thew compass was always off a bit. figured out it was the magnetic snap. i havent used a magnetic case on any android phone since, havent used any case since actually. to get the compass back to accuracy, a few firm smacks on the back helped.

VZW Screen Locking

Anyone else having issues with screen locking with the VZW version? Even when I push the power button at the top my screen comes back on in the holster.
Apparently (a Sprint owner can confirm) the Sprint version has "long press end key" built in to lock the device. I noticed that if I locked the device while using TFLO3D it would somehow get unlocked without me manually doing it.
Anyone else having same issue?
I am installing S2U2 now ... will report back
Also I downloaded LockMeLite
I have the VZW TP2 and have had the same problem, usually when I would slide it into my side pouch. It's annoying.
I would rather have it lock automatically then unlock. I think there might be something built in to it that if the proximity sensor and buttons are pressed that it auto locks. Even though at times I get annoyed that I have to unlock it, I would rather that happen then pocket dial someone...
i have not confirmed this but i think that if u have a magnetic holster, than the magnet is active like the switch that turns ur phone from portraight to landscape when u slide out the keyboard. when u put the phone in the case it passes the magnet and thinks that u just opened the keyboard
@joeyc
I have seen blackberries and model-specific holsters which do that, but I believe something else here is to blame. I have noticed this issue in my pocket, and unless parts of my anatomy are magnetic, I would have to assume something else is going on.

Yeah it does change the orientation of the screen as well so you could be right.

Yep, i was shoving it into a Blackberry holster. (until my orderd one gets here)..lol...so yeah, something definitely is going on.
i could just wave my phone infront of my case and the screen will turn on along with the orientation changing
So, is this specific to BB case which use to magnet to turn off screen when holstered (very smart), or is this an issue with all magnetic closure cases???
I haven't even found a TP2 CDMA belt case without a magnetic closure.
its an issue with all magnetic cases
From looking at other forums like ppcgeeks and others it appears that most everyone is using something like S2U2
With S2U2 installed I have no issues with my magnetic case

S2U2 it is!
question for all of you people who have recently started using S2U2...have u noticed a significant dranage in memory or battery..the reason im asking this is bc ive always used S2U2 so i havent had a chance to notice...im trying to find ways to extend my battery life bc its horrible on the newer devices
Just make sure every option in S2U2 is turned off.
Don't enable any of the options or features. Use it purely as a lock tool.
thats really all i use it as...i dont use the caller id,appts,s2p, or anything like that...will that help to increase my battery life and memory??? also, is there any other way to increase my battery life????
Is there anyway to default to S2U2 for the lock instead of the one that's on there now?
Magnetic Cases is the problem
I first had this issue on the 6800 and it turned out to be the magnetic case. The phone has a sensor looking for a change in a magnetic field- this happens every time you take out your stylus, and so the screen turns on.
The light-powered magnet used for keeping the leather hip cases closed interferes with the sensors on the phone and cause some odd, undesirable results... I prefer to play it safe and stay away from anything magnetic on a phone this complex.
Just my 2 cents...
as far as cases themselves go, i had issues like all have described in finding the right case that wouldn't do this. The HTC branded case has more room within its pouch so it doesn't effect the screen or buttons, it's magnetic and works fine. Just figured i'd lend an alternate solution besides hardware tweeks. hope this helps

Do cases with magnets damage the GPS of a Nexus?

This may be a stupid question but do cases with magnetic closures mess up the GPS of a nexus one in anyway? I remember reading something to that effect with the G1 a few years ago but am unsure if it's true or not.
It shouldn't affect the GPS itself... It will (obviously) affect the compass though, so perhaps the orientation may be misreported. GPS works on satellite signals, not geomagnetic forces.
Thanks for the answer.
it might effect the camera, i do not have a case for my Nexus (use holster) but I had a case with a magnet clasp on the cover that effected the camera on my Nokia N97, but with the fone in a case how are you going to use the GPS ?

Good point. I didn't think of that. The camera in the nexus one, as in most modern phones, uses a piezo ceramic motor for its autofocus mechanism. While not exactly working in a similar manner to standard electromagnetic motors, they are still influenced by the magnetic field. That said, you're not going to use the GPS or camera while the phone is in the holster, and the effects should be limited to that situation.
Oh, and if it's any comfort, I work with fMRI using moderately high field strength (3T). I have walked in the room with my phone before, and even though it is tugging to the scanner in my pocket, it still works completely fine today. A typical pocket magnet is 2-4 orders of magnitude weaker (1/100 - 1/10000 the strength). It will not damage anything in the phone permanently. Either that, or I have been extremely lucky.
Thanks for the answers. I ended up going with this Seidio Innocase Case and I couldn't be happier. No magnets to ruin your phone in this case
magnets can also screw with the capacitive touch screen.
Search for my post where I made a desk and a car mount using super strong hard drive magnets. I've been using it all day every day, no effects on anything except the compass when attach to the mount. Screen, touchscreen, camera, gps, totally unaffected. Compass still works fine when not mounted.

Screen turns off when the flip cover opens full

Hello,
i bought a flip cover for my Galaxy Note 8.0.
When i open it, the screen goes on as expected. However when is turned all the way to the back of the Note, the screen goes off!
It seems that also the back camera has a sensor and understands when i do this the screen should turn off.
Any suggestions to fix this?
is this and official case? if not then i'd suspect either you have one with too strong a magnet, an unshielded magnet or both.

hello,
no it is not the official case, so probably this is what you indicated.
Is there a way to stop the tablet from recognizing the case totally?
so far the only way is to cut out the magnet until someone figures out how to disable it. you'll most likely need root to do so.

thanks, any idea where exactly is this magnet?
i believe it's inside near where the case meets the edge of the device. run a magnet around it to verify the exact spot.

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"

Proximity sensor problem - it works when phone gets a little squeeze

Hi there.
I have proximity sensor problem, it is always 'on', showing 0cm of space. I've used sensor test app to check it. And of course experimentally it behaves like it always senses something.
However the case is, it sometimes works normally, so it's not 100% hardware failure.
After meddling with a phone, I've noticed when I give it a little 'squeeze' with my fingers, and now for test - with a simple laundry clip (so really not much force) it starts to work normally. Like everything is perfectly fine.
Did anyone had such a similiar case? Can I fix that somehow without disassembling the phone? What could be the cause? Some exccesive humidity? I've also ordered a protector glass from aliexpress like two weeks ago, which came with a liquid to rub around the edges, I poured a little near speaker. Could it have affected the sensor? I'm not gonna give my hand for that, but I guess the problems started around from there.
When a phone drops down itʼs hardware gets like an earthquake in it and maybe this is the issue that proximity sensor got loose and you have to fix it by disassembling your device
