Samsung Galaxy GT-Express I8730:

the sensors work poorly (rotation, liniar accelerometer, gravity)

Samsung Galaxy GT-Express I8730: any application, for exemple compass, or tool kit to measure gravity, acceleration, etc based on sensors not working (compass is blocked or deviate from north)(starting with version 5.0.2) I installed the latest version(+pa_gapps-pico): make clean install (wipe: media, cache, data, dalvik.) 20150804 [ROM] 5. 1.1 CyanogenMod 12.1, baseband: I8730XWAMK1, and I install apps from google play store. Sensor read of application Hardware Info 4.2.6. (Googleplay).

1-MPU-6k Accelerometer--Ivensense

2-MPU-6k Gyroscope------Ivensense

3-YAS532 Magnetic Sensor--Yamaha

4-Light+Proximity Sensors------Taos

5-Linear Acceleration Sensor-- AOSP

6-Gravity Sensor-----------------AOSP

7-Orientation Sensor------------AOSP

Reports: waiting for events at 6 and 7.

We need another driver for Sensors? (AOSP for exemple) Reinstall the stock rom and see what happens?

xda-developers Android Development and Hacking Android Q&A, Help & Troubleshooting [Q&A] [ROM][5.0] CyanogenMod 12.0 for Samsung Express (GT-I8730)

The problem is that the application does not work any type: compass, or planetarium.

I follow the forum for many years, and I see your enthusiasm, I often brikuit phone and I and saved, thanks to information found on the forums. Thank you!

Did you make clean install? And now you cant install apps from google play store?

yes! wipe: media, cache, data...

baseband: I8730XWAMK1

starting with version 5.0.2, has not worked compass. Reinstall the stock rom and see what happens?

I dont about this bug, maybe is better to write it on forum, someone else can help you.

What exactly is this?

1.-In application Hardware Info 4.2.6.apk, Line 6 refers to gravity sensor status. Row 7 to orienttation sensor that is not working.

2.-Multitasking works, phone work, you can open other applications, compass pointed North Pole wrong, continually oscillating 10-20 degrees. 360 degrees rotation of the phone maintains the same position to the north of phone. Possibly because AOSP drivers?

3.-3.-Androsensor.apk (Sensor Snapshot)

in ghica54 's Profile-about me, I have attached a photo album with screnshoot with sensors.

Thanks for the reply, for your attention!
