Hi
After downloading an app calles Sensor Box I saw that on my rooted device (sm-g3858) (stock rom) the orientation sensors, magnetic and gyroscope sensors are missing. Is there any way to add them? Are these sensors hardware based? GPS works fine for me so is there a way to implement these 3 mentioned sensor functions? Available in the phone are accelerometer and proximity sensor so I want to know if I can add the others by adding certain xml files

Sensors are indeed hardware. You can't simply "add" them. If my memory serves me, the only practical use of a gyroscope sensor is for Photosphere. Lots of devices are missing this. It's odd that your phone doesn't have a magnetometer. It's also odd that there's no orientation sensor. To be honest, I don't think that your phone is missing a magnetometer or orientation sensor. I mean, if you're watching a video or viewing a webpage and the display rotates, then clearly it has that sensor. And most phones have a magnetometer. Your phone (Galaxy Beam 2) is kinda a specialized device, so I guess it's possible that certain things common to other phones were omitted. If that's the case, it's unfortunate, but sadly, you can't "add" them via software.

thank you for your reply. Maybe that function is not activated? Samsung pretty much sucks when it comes to software support so maybe some files are just missing. Do you know where I could find the location of these files? The problem is that compass apps for example need that function (unless you know of an app that doesnt..)and I might not be suprised if Samsung just didnt add the files to /system

I really couldn't help you with that. I doubt anyone could. I would suggest, however, that you try a couple other apps. Phone Tester, Sensor Kinetics Innovations, to name a couple. Also, some basic apps that use these functions. Most compass apps use the magnetometer, and there's also metal detector apps (obviously, you'll need something steel or iron, not just any random metal). And as I said before if you're viewing a webpage or video or something, and you turn your phone sideways and what you're viewing changes its orientation, then you've obviously got that sensor as well.

I tried Sensor Kinetics and when I change the orientation the Accelerometer is effected. So basically the orientation sensor is the accelerometer in this phone. And I can also see that in the demo option. But anyway I tried several metal detector apps and there is 0 reaction. So I guess thats it. Thanks for your time.

Hi all,
Is there a security app out there that allows fingerprint login, as well as unlock.
thks.....
I don't see how that can be possible? THere's no fingerprint reader on the HD2, unless its hidden very well
What do you think this phone is? a futuristic phone made in 2030? lol
How about ear-print recognition via multi-touch?
Screen used as finger print reader

Before you mock too much, my guess is the original question is being asked because the LG eXpo phone supports this (albeit by a specific finger print reader built into the navigation rocker). It uses this finger print read instead of a password on the unlock screen (very cool).
I'm not sure whether this function could be applied to a section of the touchscreen on the HD2 as I imagine the specific finger print reading technology is quite different from a capacitative screen interpreting a press...
missing hardware, therefore impossible.
I don't think it's such an outrageous question.
Supposedly LG already implemented this feature, so it can be done.
Could fingerprint recognition software be developed based on barcode reading software?
If so, I think there might very well still be an issue with using the camera for fingerprint recognition if you'd want to use it for device access purposes.
Being "logged off" the camera would be logged off too I guess...
But hey, a lot of wizzkids frequent these forums...
Facial recognition would be possible I think.... er... it would also be easier if there was a 2nd front camera!
Honestly, I dont need it... but it would be cool I guess and some people would. I use EWallet for all my sensitive stuff...

erm.. actually japanese phones have had these features for the past 2 - 3 years already...
They also have facial recognition access.. and also various gesture unlocking features...
The screen can only detect areas os pressure, not the individual parts needed for fingerprint. The LG one I assume works by sliding your finger over the joystick?

The fingerprint capable Japanese and Korean phones have built in dedicated fingerprint sensors.

You spot on! We just need a good developer to take in initiative.
The HTC sedna (which has its own section here) has a fingerprint scanner.

The iPaq pocket pc already did it BUT.. yes.. BUT that is hardware dependent. Fingerprint scanners are hardware depended. Don't ask too much.. If you are talking about using the camera as a fingerprint regconition scanner, I wouldn't rely on it too much.. its like using the camera as a name card scanner.. not accurate enough..besides, it would be a hassle to aim the camera to the finger just to unlock the device..
facial recognition is totally different from fingerprint sensor.
if you recognise fingerprint (which is far more complex than just facial expression) then you are probably going to recognise a dozen (or more) fingerprints to be the similiar one. For facial recognition application, this might be acceptable, but for fingerprint application, due to its nature/purpose of it, this will not be as it'll be a security breach.
so it has nothing to do with competency of the developer, w/o the hardware, regardless if you have a world class developer or s/w.
come on people, think!
as long as there's no hardware sensor for fingerprint scanning, there will never be a piece of software that's able to scan your fingerprint from a touchscreen, whether it's capacitive or not.
a touchscreen recognizes finger presses. but in order to get a fingerprint you really need the ability to read those small, fine lines of your fingerprint.
You guys are just too much! We can hack these phones a lot but not everything can be accomplished by changing a registry setting or installing a patch!
Looking for fingerprint recognition on the HD2 is like trying to take pictures on a phone without a camera. There's no app for that, just as there's no app for driving your HD2 to work or making toast with it.
Every single device that can recognize fingerprints (like the Toshiba g900 I used to own, and also the LG one) needs the dedicated hardware.
The capacitive screen is absolutely unsuited for this (see the explanation above) and I don't believe the camera can do it either. Barcodes are simple black and white lines for a reason. High contrast makes them look more or less the same in most lighting conditions so they're easy to recognize. Try taking a few pictures of your finger in different lighting: the difference between those pictures will likely be much greater (to a computer doing visual analysis) than between two different fingers in the same conditions.
I don't want to discourage thinking outside of the box, but this is a bit too far out I'm afraid.
Hello all ... I'm sure this is a simple question ...
My wife has a stock d2vzw with 4.3 installed. The proximity sensor next to the front-facing camera seems extra sensitive; anytime a stray object/finger crosses it's path the screen turns off. My guess is this is a power-saving feature whenever the phone is turned over or placed in pocket, etc. However in my case, it is just super annoying and I would like to disable it. (in contrast, my CM10.2 d2vzw doesn't seem do this by default)
Can someone point me to the option needed (in stock 4.3) to disable this, or perhaps extend the time so that it doesn't black the screen instantly? I've poked through most of the menus and can't seem to find it ....
Thanks

You can't disable the sensor with stock rom. The sensor is either on (value 5) or off (value 0) so there's no time setting for this. You have to be rooted in order to disable the sensor. Some technical people reported that they have take the phone apart and clean it, but if the sensor is defective, you either replace it or disable it. Also you can download an app called proximity sensor finder and test your sensor, open the app and wave your hand over it, you should see the value changes from 5 (not cover) to 0 (covered).
Thanks, I'll try it out.
However, is there a setting somewhere that will simply disable the feature of blanking the screen based on the proximity sensor?
With this same phone, I don't think I ever observed the annoyance with 4.1.2 .... it looks like the sensor/blanking is either something new in 4.3 or perhaps some default value/option was reset when the phone was upgraded.
Thanks!

Do a factory reset. The ota has a lot of side effects if you do not reset.
Hi!
I have a question. Is it normal that when i check my sensors, which are responsible for move detection like accelerometer or gyroscop they are all "shaking". That shaking is visible also in app like sky map.

Are you on stock rom?
Yeah. I'm using Franco Kernel and Xposed Framework with gravity box, but still i'm on stock. I should mention that i'm using z-device test to check my sensors. Could somebody check how it looks on other phones? How it looks on your Nexus 5. Just to be clear that "shaking" isn't big it looks like little simple harmonic motion detect by phone, when it's stay stable on table.
Hey guys,
New smartphone user here. I've had Nexus 5 for a few months now.
Lollipop is really well made and the new visuals are great. Everything seems to be working well so far, except for my compass. It does not work either in my Compass app or in Google Maps. I've seen a few threads where people lost some of their sensors, so I downloaded Sensor Box to see what it would find.
The magnetic sensor works properly, but there isn't a "compass" sensor in it. Are they different or is the compass position determined using the magnetic sensor? The GPS Essentials compass does work, but it feels very slow and it's all over the place.
Additionally, when I start my Compass app, it does not activate Location like GPS Essentials would, although, it fetches my current address properly on top of the compass itself. (see attachment)
Could it be just that the compass works in a different way in Lollipop and apps have to be updated for it? I'm completely lost. Any help would be appreciated, guys.
Cheers,
I am experiencing the same issue.
I'm also having this issue, only app I did get it to work with was Compass 360. But I really only would need it for Google Maps, so this is still very annoying.
Did anyone come up with a solution, or at least an explanation yet?
Or does anyone know where to file a bug report about such an issue?
Are you sure the APIs just didn't change with Lollipop? If one app works and not another, it may not be a Lollipop bug.
Kompass is dead on for me, no issues whatsoever. Try moving the phone in a horizontal figure 8 to calibrate the kompass and watch for electrical/magnetic interferences.
Hey! I'd like to ask a favor from someone with a Zenfone 7 in their hands. Could you tell me the driver name of your proximity sensor? You can check it by using Sensor Box (free on the playstore).
I'm asking for this because it seems my phone doesn't even recognise the driver and it just displays as ASUS Proximity Sensor, opposedly to other sensors that display their true name. Maybe I'm tripping and that's just it's real name, but I'm almost sure it had a different name before the sensor started malfunctioning.
I'll attach a couple screens. Thank you in advance.
Here's some screenshots from a borrowed Zenfone 7 Pro, as you can see it's named the same.
To be sure we don't suffer the same fate I did some tests to confirm that sensor is working.
@zcrubby Thank you! Indeed your sensor works well. I'll keep trying to figure out where to find the root folder of the proximity sensor driver to disable it, since I was able to get sensor disabler functioning but didn't do the trick with the proximity sensor. Would you let me know if you know something? Much appreciated!

Any luck in disabling the proximity sensor? I have a strange bug wherein every restart of the device causes the first instance of the camera to flip upside down and come up with the camera obstruction error. But once you click ok several times it's fine.
