Faulty magnetic sensor?

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.

Use of the Grip Sensor

Hi everyone,
i just went through the *#0*# test with my Note.
And i noticed our Note 10.1 2014 has the same good old grip sensor installed the old Note 10.1 has. It triggers when you hold your note on the left side.
I did a quick search for "grip sensor" in google play and found nothing. It seems like no app uses this great sensor build into our notes.
I think this is mainly the case since nobody even knows about it.
So i start this thread now to solve this.
Do you have suggestions on how we could use the sensor?
Can someone write an app that uses this sensor? - or integrate it in an existing app
Feel free to post suggestions and your thoughts about it

Yes, but this doesn't answer the question: What does it sense?

I have a case that covers the sides, does that make the sensor useless?

Hmm it senses the electromagnetic field of your hand perhaps?... im no expert
but it even works if you hold your hand within a 1cm range behind the note. You do not have to touch it.

Nope it works through covers and even through thick cotton.
But try it yourself by dialing *#0*#

I have to add to what one of the previous users posted. This still doesn't answer what it does. What does it trigger? What could it even be used for?

it seems like it triggers nothing... perhaps samsung knows what... but its intresting that they still have the sensor build in "without" using it.
it could be used obviously to detect if you have your device in your hands..
.
You could for example try to use it to hold your device awake while holding it... but i cant say if this works without trouble...
also you could use it as a "button" - for any function in any app.. hmm in games... you have to be creative i think xD
But finding usecases for this sensor is also the reason i started this thread. So try it out with *#0*# and feel free to post suggestions

I ve been trying to turn the screen off & on when you open & close the flip case. Found that the grip sensor dustinguishes the open case from the closed... but how to use this to trigger the screen to turn on & off, I ve no clue.... any help d be appreciated.

It is on every samdung tablet

actually the two lines at the bottom of the device are the grip sensors.. when u cover it it will vibrate when u r testing the GripSensor.. but dunno what is the purpose of it

not only from the left side, actually it will trigger when you cover one of the lines at the bottom of the device, but dunno why they are used for

Its used to block out your hand when you are writing on S Note so you dont accidentally hit the back key with your palm.

Use of grip sensor
From everything I've read the grip sensor is to detect if the device is in a case/cover but as to what cares about case detection is another thing, perhaps Samsung's OS uses it

Maybe it's used for the On Body Detection lock for Smart Lock in Security option?

What about left handed people..?

Maybe Google's smart-lock uses it for the "on body recongition" because when I set my phone on the table it stays locked and when I slap my hand on the geip sensor (where the battery is) it unlocks.

Grip sensor in my note 5(SM-N930G0) is always on.screen never turns blue when i perform the test.
and due to this reason phones battery performance is very low.
Does somebody know how to fix this.
Thank you

[Q] Light sensor not working

Hi everyone
I have S4 i9505 I got it second hand
I noticed that the auto brightness not working
I make sensors test and her is screen shot for result
Another scresc shot from galaxy sensors app (3rd sensor says waiting)
Any idea how to solve this , is it SW or HW issue?

It is hardware issue
The hole whre you insert handsfree get some blower that blow air with pressure
Blow it properly hope this work

Try comparing your phone with other S4's with smallest differences.

Screen brightness not work after screen replacement

Hello
I replaced my Galaxy note 3 screen, everything is working good. But it seems I lost the brightness. It is on a high brightness and does not go down, even when I put auto. I need to lower the brightness, because of saving batteri and for a better reading to my eyes.
Do you have any solution? Is it a hardware or software issue?

Was the replacement an original Samsung? If not, many third party replacements don't support auto brightness.

I think it wasn't an original Samsung. But are there any way to make it support or fix the problem?

You could look for apps in the play store that might help.
Did you try a factory reset of the phone?

No actually I didn't try a factory reset, should I do that?

I don't know how much battery power the app will use. When ever I had to replace a screen, I just looked for a phone with broken internal components and a working screen.
Try a factory reset but make sure you have a backup of your data.

I just factory reset from recorvery menu, nothing changed, the same problem

Have you tried contacting the seller and asking for assistance?
I can't think of anything else to suggest.

Are you sure you not covered the light sensor. Maybee forgotten to remove the protection foil. The light sensor is beside the front camera. Is the front canera working?

Both the light sensor and front camera are working

Have the same issue with samsung s3, Everything works fine except the brightness won't budge, the light sensor is working fine. I checked with sensors multitool and it responds so there is no question of sensor being blocked or damaged.
I agree that with 3rd Party replacement Screen, Samsung just doesn't want to work, I would have gone for another device for the price I paid for the replacement display but I didn't thought of it at that time. anyways, Samsung sells crap, I have seen so many users having issues with their displays, even the newer ones. I have stopped investing in Samsung anymore, lost trust, feels like been betrayed with the one that I fell in love.

Auto brightness often doesn't work with any 3rd party screens on any phone.

How do I... turn off display when cover closes on my case

When I put my phone to my ear the display turns off.
When I move it away it turns on. That is GREAT.
Now, how can I enable this activity when I open and close the cover of my phone case?
My old S4 did this but I cannot find a setting.
Thanks!

Look for kinscreen on the app store.

When on a call, the proximity sensor is active and controls the screen. Having it on 24/7 will impact battery.
Generally, a magnet is used to trigger the same thing with a case. A different sensor or switch than the proximity sensor is used and a magnet in the case triggers it. It's possible that the Essential doesn't have this sensor that gets triggered by a magnet or your case doesn't have a magnet.

The cover has a magnet. Using the app mentioned above solved the problem. Will be interesting to see impact on the battery life.

The phone may not have the sensor for the magnet to work then. Good luck with the app. It may not be too bad as it may only enable the sensor while the screen is on.

Proximity sensor. Reducing screen on time offsets the energy cost of polling the sensor.
