Do compass and gyroscope is really a must in smartphone? - General Questions and Answers

hello, im think about buying Lenovo P70 which doest have compass and gyroscope sensor... just want to ask, do these sensors is really a must in smartphone or it just okay if is not in the phone... im rarely used compass as i dont know what to use for... or there a lots of apps need to have this sensor to working? i really want to buy this phone but these sensors really confusing me whether it should be in the phone or not... please answer... thx

Although these sensors are becoming more popular in android phones, I do not think most of the apps on the market are using them. Compass and gyro can be used to measure the devices position in 3d space more accurately than the standard accelerometer, but this is not necessary in for example majority of games. If you cannot come up with something that you need these sensors for, they are not necessary. Including these sensors may increase the phones price a little bit, but not by much [citation needed].

[Q] ipad 2 proximity sensor like function

Hey I was just wondering if it is possible to gain the same function as the iPad 2 has with its proximity sensor with our gtablets since we have a light sensor?
I'm not sure if it has already been asked before or if the devs are working on something similar but to me it would just make our already amazing tablet even greater
I'm not 100% sure, but I think a proximity sensor requires both a transmitter and a receiver. I assume IR.
I think iphone & ipad use light sensor to make a trick on the proximity sensor, if the light get completly darken it will assum that the device is close to a hard surface, ie: the face in the case of the iphone, so i assume that it will be posible to do so with a little software trick ... btw, anyone know which ROM take the advantage of this light sensor setting in use? don't see it on Vegan ..

PhotoSphere on Moto G

Hello friends, I have a question that is because the camera JB have no option to photosphere?
The specs say that the Moto G has Gyroscope.

Moto G doesn't have a gyro sensor, so this is the reason why Photosphere won't ever work.
Are you sure it has no gyro? Some site report it has gyro, some other no.
You can try installing photospere.apk and check if if works

The Moto G has an accelerometer. Since it's able to determine X/Y/Z I was able to play Ridiculous Fishing on it. So, I have no idea, why an accelerometer shouldn't be enough for Photosphere to work properly.

Accelerometer and gyro sensor are completely different types of sensors, read Wikipedia.
I suspect it doesn't have a gyro because all sensor test apps report that there is no gyro sensor...

Hang on a moment the Moto G does have a g-sensor. Explain why Temple Run works when it requires a g-sensor for its tilting functionality? There are some videos on YouTube that show the Moto G in action by tilting it, which would require a g-sensor to be on board. An Accelerometer only measures speed/motion, and is used on some mobile devices to determine if the device is in landscape or portrait orientation.
A g-sensor (Gyrometer) determines where a device is on an axis (eg to see where the device is tilted and by how much).

Temple Run (and other games like RR3) rely on accelerometer. It doesn´t need a gyroscope. Sorry.

The g-sensor is the accelerometer, not the gyroscope. The accelerometer measures the device's acceleration compared to the free fall vector (the direction of the g-force), and the gyroscope measures it to a fixed axis of the phone itself.
If you are somewhat handy at flight dynamics, you should know that a plane has three dimensions of rotation: the roll, the pitch and the yaw. An accelerometer can only measure roll and pitch because the axis he yaw is measured to is the orientation of the gravitational pull. Because of he gyroscope has an independent reference axis it can measure all three dimensions which is needed not just keeping a plane safely in the air, but for the photosphere feature too.
How does a level app works then? Smart Tool is able to display pitch and roll correctly
Edit: Found my answer, it has a multipurpose AK8963 magnetometer which also provides orientation and hall effect (magnetic cover screen on/off)
Moto G does have a gyroscope. I'm not sure if it's just the 4g edition or not, but mine does.

Oh okay. Makes sense.
photosphere alternative without gyroscope
Crystal Photo Surround is the best alternative (or perhaps the only one I could find) to photosphere that works on my Moto G 1st gen without a gyroscope (2nd gen has got gyroscope). Eventhough the app needs some improvement and is tiresome to capture, it's fun! Shots captured in it won't be recognised as a photosphere in Google+ since it doesn't embed the META data, required to recognize as one. It can be viewed in the app though. I think it uses accelerometer and magnetometer in place of gyroscope. Hope the developer comes up with an update which will make shots captured in it is recognize as a photosphere or some other developers in this forum can possibly develop an app on similar lines.
If you want to try it, head over to play.google.com/store/apps/details?id=com.npisunflower.photosurround

Sony IMX214 image Sensor

Hi Community,
i am really new to smartphone hardware and dont have much knowledge, so sorry if my question is a bit stupid ^^
I am owning an UMI Zero with the Sony IMX214 Exmor 13 MP Camera Sensor. With the original Software this sensor produces so much noise, the pictures really aren`t good.
So i was locking for other devices ( Phone´s / Dashcams ) with exactly the same Sensor. For me it seems like that other devices handle this sensor way better than my Phone.
Also this Sensor should not be bad i`ve read. So i wonder if there is any way to tweak my cam ? I installed a Custom Rom on my Umi and it really feels like pictures are looking much better now.
Also i`ve read ssenssor specifications and saw that this sensor is able to record 4k in 30 fps. Is it possible to unlock this features somehow? Is anyone willed to help / explain me why or why not? Is it more a hardware thing like Digital Analog Conveerters which are used or OP amps which are used in hadrware? Or is there a way
that Software can improve this really much ? Maybe there is a possibility to install another camera driver to my Phone?
PS: I am really sorry if this is the wrong section ! I am pretty new to this forum, if anything is wrong pls tell me !
Thank you very much !
Greetings,
Dom
This is a combined of software and hardware.
Your custom rom ave enhanced the software to limits now if you know a genius then go to haim and get hardware twicked othwrwise this is it man.
You have done what anyone can do.
But if you are mot satisfied then just check the file at this path on android
/system/etc/media_profiles.xml
And if you know what you are doing go ahead amd mood it.
Peace

The phones with the best / most accurate compass sensor

Hi,
I want to write an Android app which relies heavily on the phone's compass.
I'm looking for a phone with a compass sensor as accurate as possible and low latency/inertia.
Are there any reports on comparisons between different phone models or makers..?
From what I've searched HTC, LG and Huawei phones seem to be good as far as the compass is regarded; HTC uses Asahi Kasei's sensors.
I could find more complaints about Sony's Xperia.
I'm thinking of choosing from HTC, LG, Huawei, Galaxy, ZTE, maybe Xperia but I'd like to know some legitimate opinions first.
I'd appreciate if anyone could share knowledge.
Thanks.

IR Blaster - Code learning and finicky aiming

Hello!
I have recently apgraded to an F2 Pro and so far I'm in love. I upgraded from an LG V20. Both of these phones have an IR Blaster.
The V20 was able to scan/learn ir commands by pointing a remote at it's blaster. Can the F2 Pro do this hardware wise or just software limitation ? I have not found this option in any remote app so far.
The Poco also seems to have a weird blindspot? I usualy need to point it slightly up/down/left or right of the device for it to pick up the signal. Never had this problem on my V20. Might be just my unit though, that's why I'm asking.
You'd need an IR receiver to learn the ir commands, and the poco f2 doesn’t have a dedicated one. However the cameras on electronic devices are sensitive to light in the infrared spectrum, and you could use the regular cameras as a hardware fallback. The miui remote app doesn’t have this functionality, but it sounds great ! hopefully someone will make a third-party / opensource version !

Don't you need really high FPS to use camera to get usable info from camera as an it receiver? Do you know if any apps actually do that?
Its not possible. Yes, in Theory (and only y theory) a very high speed camera could doing some magic. In first instance, you will need a camera camera of 50000fps in the best case. And this is only de first problem.

Well that makes sense, I learned something today ! In that case I see how it would make things more difficult. I don’t know of any app that does this, sadly.
