[Q] Light Sensor

Well i am very confused whether our phone has a light sensor or not. In the official user manual of I5801 (English-India), at page number 17, its clearly stated that the left one of the two sensors on top left side of our phone is proximity sensor and the right one is light sensor. If there is one, then why is there not any option for automatic brightness? and what its use is? And if its not there, then why is it given in the User's manual ?

Does anyone have any information on this at all? Was/is there any rom that supported automatic brighness via the light sensor?

So why isn't it included in Samsung' Stock Rom ?
Do you think really that no-one ever try to use it .

There is no light sensor on Galaxy I5800/5801. The proximity sensor is actually a pair of sensors, one sends an electromagnetic/Infrared radiation while the other one is to receive it back for the sensor to get activated.

Wow, this is kinda shocking news!

Proximity Sensor calibration?

is there anyway to calibrate the proximity sensor on the sensation, not 100% sure thats my problem but worth a try if poss

Would like to know this as well.Proximity and light sensors not working properly on my Sensation (only occasionally).

I'd like to know how to recalibrate / get it functioning again.

Yes,i like to know that to.
Still having problems with both proximity and light sensors...

The proximity and light sensors cannot be calibrated, as they put off specific amounts of voltages based on results from the input. It is up to the ROM/Kernel to interpret the voltages from the sensors as usable values to produced the desired results. If you wish, you can download a testing program such as AndroSensor to view the interpreted sensor readings.

Proximity sensor

I was wounding if someone here could tell why Proximity sensor only works at night?
Thanks in advance

no answer

Has no one ever seen this?

Kernel settings probably or sensor problem.
But you better try another compatible with your ROM kernel or search how to edit it's settings.

I used several different roms and this is always the case.

The proximity and light sensor are different. The intensity sensor sure has more sensitivity at night, but the proximity sensor has its own IR. It will work just well in both day and night.
If you have this problem on all ROMs, you might have a hardware issue. Try updating your firmware.
Happy to help.

I'm running 3.33 firmware and this happens on all roms, not sure why but light and proximity stop working at same time and they both start working when room is dark.

Screen won't turn off during calls

Hi there. Screen is not turning off automatically during phone calls for me. Is it normal on Droid Turbo/ Moto Maxx? Does it have proximity sensor? I have tried stock dialer and SIP dialer cSIPSimple. I am still on the stock ROM, locked bootloader. Thanks

Yes, it has proximity sensor.

Works fine on all mine and my wife's XT1225 phones.

xposed gyroscope not working

SO, I have rooted my device, installed xposed and virtual sensors and then reboot it but it still shows false gyroscope. why?

Hi, what is your smartphone ?
We need more some informations to resolve your issue

I think this is a china phone? Qnet cyrus.

Ok i think cause your Qnet Cyrus had Accelerometer and not gyroscope
It's not the same thing,
An accelerometer is used to measure a linear speed variation.(speed when you drive in car)
A gyroscope can measure a variation of angle.
In some cases an accelerometer can measure the inclination but this is due to the fact that with two remote linear accelerometers, one can calculate an angular acceleration....
Your Qnet Cyrus had an accelerometer but only for measure a linear speed variation.

you must have both accelerometer and magnetic field sensor in order for the xposed app to work, if one of them isn't available, then the xposed app isn't going to work.

ahh, so I still need a magnetic sensor to work,okay
how can I get a magnetic sensor? or can't I?

Idk if your phone have it, but if it doesn't built in your device, then there's no chance for the app to work, variety of devices have different sensor built in with them, you can't install it by yourself because a device have specific types of board and component, if they aren't match, then there's no way it working, if you want gyroscope so badly.as an advice, why don't you buy a device that have gyroscope built in instead of searching a device that have magnetic field sensor?gyroscope sensor are more efficient instead of using software that provide same functionality.

For your post >>>>>>>> go read the fourth post when i ask you your smartphone's brand
You haven't in your smartphone so . . . . .
If you don't have the physical tool you can't virtually emulate with an app the action that is induced by the physical tool
