[Xposed] [Testers needed] Trying to solve Light sensor bug - Xiaomi Redmi Note 3 Themes, Apps, and Mods

Hi, may be some of you have experienced the bug when an auto-brightness is on and you're in the dark place or light sensor is covered by your hand or cardboard and you're trying to watch 360 video on youtube or other required gyroscope thing and there are lags. Watch them on video - https://www.youtube.com/watch?v=XYudbTzIdHU
May be it's already been discussed but I haven't found the solution except turning auto-brightness off which isn't like a perfect solution to me
On 4pda user GODKIMOVSK have shared some info regarding this problem. Here few things you should know:
1. There are two different kind of light sensor installed on our devices:
a) Liteon LTR55X ALSPRX
b) Sensortek stk3x1x alsprx
A lot of users with gyro bug have Liteon sensor but there are people with second one as well.
To check what sensor is installed on your device use Sensor Box application.
2) The limits of light sensor usually are 0 - 10000 lux and gyro lags exist only when the data from the sensor is less than 10 lux.
So, the solution is quite simple seems to me. When the sensor read value that is less than 10 lux it becomes 10 lux on the out of the sensor.
I found a xposed module http://repo.xposed.info/module/com.mrchandler.disableprox - which able to mock all sensor 's values on your device. But I haven't tried it yet cause my boot is still locked and I don't want to unlock it unofficially so I'm waiting for xiaomi to allow the unlocking.
The module doesn't able to change light sensor measurement limits but it can replace it with one number. And if it actually does that's almost the solution.
THE FIRST TASK.
I need people which have the described gyro bug to test the Sensor Disabler xposed module.
1. Install the module, activate it in xposed installer. Go to the module setting, find the light sensor and mock its values to 50-100 lux . Reboot.
2. Turn on auto-brightness. Install Sensor Box or any other application which can measure light sensor data. If it shows exactly the same value in lux that you set up in the module then it works.
3. Try to experience gyro lag. Go to youtube and try to watch any 360 video with your hand covering light sensor.
4 . Share your results in this thread. Does the module work or not? Does the lags are gone?
Share xposed log too (/data/data/de.robv..../log/ and the file is error.log or something like that) so if the module doesn't work we can identify what is the reason.
THE SECOND TASK.
I saw source code of Sensor Disabler module and built my own module (Light_Fix.apk) with following code which is aimed to solve the gyro bug.
Test my module as well and share log.
Steps are almost the same except 2nd step:
2. If the data can not go less then 10 lux then my module works.
PHP:
private void ChangeSensorValues(final LoadPackageParam lpparam) {
XC_MethodHook mockSensorHook = new XC_MethodHook() {
@SuppressWarnings("unchecked")
@Override
protected void beforeHookedMethod(MethodHookParam param)
throws Throwable {
int type=(Integer) param.args[0];
float[] sensor_values=(float[]) param.args[1];
if ((type==5 ) & (sensor_values[0]<=10)) //type 5 - LIGHT_SENSOR afaik
{
XposedBridge.log("SOMETHING WORKS!");
XposedBridge.log("type= "+ param.args[0]);
XposedBridge.log("values= "+ param.args[1]);
sensor_values[0]=(float) 10;
param.args[1]=sensor_values;
}
}
};
XposedHelpers.findAndHookMethod("android.hardware.SystemSensorManager$SensorEventQueue", lpparam.classLoader, "dispatchSensorEvent", int.class, float[].class, int.class, long.class, mockSensorHook);
}
I am also open for help from devs and other people. It's just sad that no one hasn't even tried somehow to solve the gyro bug despite so much people have the phone.
To mods: please move that thread if it is not in appropriate place​

another one to test

i will try and let u know .... thanks for trying to fix it ....

I know this bug from cm roms, never seen it on official. right now I'm on xiaomi.eu, the bug is there with automatic brightness turned on and off but the fix isn't working for me at all.
Edit: I noticed I need to turn off auto contrast aswell to get it to work with auto brightness off. I will test the module later again
Edit2: your module does nothing, it shows 10lux minimum when covered like without module. Can't find any logs. The other module causes extreme lags and auto reboots

---

Seems the problem is deeper than I thought. May be even it is not possible to solve by xiaomi itself. But I will try to get some logs from both light and gyro sensors later when my boot will be unlocked. May be some solition will be found. If it will I will share it. Thanks all for tests.
I will be appreciated if someone will try Xposed module called gyroscope noize filter and tell me if the situation with lags gets better.

Click to collapse
If with my module it shows never 0 lux but 10 instead then it works. and it works as others testers reported

I noticed my finger is not enough to get 0 lux without the module. it shows 0 when covered with something dark. and it shows always 10 with your module.

alright. This is sad but I doubt that the problem could be fixed by users itself. May be it is kernel related thing but I doubt that too.
I think people with "the gyro problem" should massively report xiaomi about this bug. This is how I'd described it after I've done several tests: "When the phone reading simultaneously data from light sensor and gyroscope/accelerometer sensor and the data from light sensor less then 10 lux it causes sudden drop in FPS - from 50 down to 4-10 FPS. "
