General :: Magnetic And Orientation Sensors Not Working On MTK6577
Dec 6, 2012
How to make the following phone's magnetic and orientation sensor working? Both of these sensors are not working on my phone (verified by many apps such as Z-deviceTest, AndroSensor and Android Sensor Box).
Various applications have shown that this phone has 5 sensors :
- yamaha530 Orientation Sensor : 0.25 mA by Aichi Steel
- yamaha530 3-axis Magnetic Field Sensor :0.25 mA by Aichi Steel
- bma222 3-axis Accelerometer : 0.13 mA by The Android Open Source Project
- tmd2771 Proximity Sensor : 0.13 mA by Capella
- tmd2771 Light Sensor : 0.13 mA by Capella
Phone name : Clone Samsung Galaxy III S9300
Manufacturer : alps
Model: e1901_v77_jbl1_9p017
CPU: MTK6577 Dual Core 1.0GHz
Android version : 4.1.1
Baseband version : MAUI.11AMD.W12.22.SP.V15,2012/10/08 20:09
Kernel version : 3.4.0 (root @ abc-desktop) #1 SMP PREEMPT Mon Nov 12 18:32:14 CST 2012
Build Number : e1901_v77_jbl1_9p017_20121105
Perhaps there is new ROM or kernal that can handle the sensors better?

After porting ICS, derived sensors are not working.when i browse through SensorService code, i found that in ICS derived sensor data is computed only if accelerometer, magnetometer and gyro are present.I dont have gyro in my device. Is this the reason for failure?

Does anyone know the difference between the orientation sensor and magnetic field sensor on Android?Since I've read that magnetometer is synonymous with digital compass I'm a little bit confused. What are they really?

Last night i have downloaded Dolphin to play Wii Games. As you can imagine, play with the mouse is not as comfortable to emulate Wiiremote.
My idea is basically:
Control WII emulator with Android Sensors (As accelerometer, gyroscope, inclinometer) like Wiimote does
It seems to be quite interesting, I think that may be connectable by wifi and bluetooth with receiver (pc).

I'm desperately trying to install a new recovery to install new rom, the phone will not turn on anymore, when I connect it is not detected (with the usual beeping sound on your computer).
I found online a full backup of a MTK6577 (boot.img, preloads, logo, recovery, etc.) I put all these files and made the procedure of flash with the software flash tools, the operation is completed I came out the green circle all that went well, but the phone will not turn on anymore.
The only strange thing is that I can load it with the power supply, this is because I use a cable that makes you see when you are charge(see attached file),this when there is no charging source will turn off automatically.
I have buyed this phone by this store: ([URL]...), I tried to apply for a refund, but they are gone (as usual)
I tried to click on the back button (reset), but there is no button on the inside.
Any possibility of recovery in some way, even opening the phone, otherwise they are thrown money.

i bought a mtk6577 clone s3. My problem is sometimes i rebooted phone, after opening proximity and light sensor doesn't work. screen don't turn off in call and doesn't call the person displayed on screen when i take ear. And battery drains too much. (example: when proximity and light sensor works with %90 battery, when it doesn't work after reboot plummets to %50).Another issue is when i reboot phone, boot animation doesn't show when proximity and light sensors don't work.

I have Sharp SH837W, when I try to install CWM, I wrote it to address 0x0 and it is bricked. I know I write something over its Preloader.
I tried but can't write down preloader again.
I tried to find TestPoint, maybe I found it but I don't know what should I do with it. I connect the test point with USB -5v and connect cable but still can't write anything (I got error 5054 in SP Flash Tool).

The magnetic sensor in my stock rom (JB) is deviated from the direction. and it is due to faulty sensor files in the stock rom. The sensor works perfect in old ICS version.
Calibration apps wont work because the problem lies in the sensor files itself

I'm the proud owner of the HTC Magic on Vodafone UK. I'm loving the Android.I have to say that after 5 days of owning this device I'm only left scratching my head on one point the auto-orientation of the home screen.I've seen videos of rooted G1's running the hacked 1.5 firmware and the recently posted video of the Samsung i7500 with the 1.5 firmware all CLEARLY show that when the device is on home screen, the desktop (read home screen) auto-rotates depending on the orientation of the device. The Samsung video shows it working in ALL FOUR orientations!This doesn't happen on my Magic . Flip the orientation in an application? Works fine. Flip it back in an application? Works fine. Do it on the home screen?Am I missing something? Is this a feature that is disabled in the offical 1.5 Cupcake release? If that's the case - fine with me. I'll stop scratching my head and move on.

I have a widget , thats working just fine in a particular orientation, but the moment i change the orientation to landscape/portrait, the widget is not able to launch. I have one layout and one layout-land folder in res directory.The problem is that the widget created in landscape mode is not opening in portrait mode and vice-versa.

I've racked my brain for hours over this issue. I have created a main.xml and designed one for the res/layout-land (landscape) format and another one for portrait in res/layout. When I rotate the emulator (ctrl-F11), my app rotates properly to landscape using the correct main.xml, but a subsequent rotation back to portrait just keeps the landscape mail.xml. This was done in a 2.0 AVD.. Out of desperation I downloaded the new Sample Code for Multiple Resolutions and had to create a new 2.1 AVD, to my surprise rotation with this app works correctly as expected. So I then decided to try my app on the 2.1 AVD and it works perfectly. So, is this a Bug in a 2.0 AVD or is there something special I need to be doing for < 2.1 SDK versions?

I download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downlaoding. Orientation changes, Activity is restarted and then my AsyncTask is completed.I want to dismiss the progess dialog and start a new Activity. But calling dismissDialog sometimes throws an exception (probably because the Activity was destroyed and new Activity hasn't been started yet).What is the best way to handle this kind of problem (updating UI from background thread that works even if user changes orientation)? Did someone from Google provide some "official solution"?

A simple question: How do I register for multiple sensors? I just switched from registerListener(SensorListener listener, int sensors, int rate), which is deprecated, to registerListener(SensorEventListener listener, Sensor sensor, int rate). Previously, I could use " | " to indicate multiple sensors, but now " | " is undefined, so how?

I'm programming an Augmented Reality application. It's development it's in an advanced state but I can't place the icons on the screen so still as anothers programs does (Layar, in example). This is because of the continuous variations of the sensors. I've tried the three modes of the sensors (FAST, GAME, and NORMAL) but I only get them to move more or less fast. The shivering is the same at different speed.
Finally I thougth I could reach my goal with a digital filter, averaging historical values. But again the icons continues moving, specially the most far placed ones (in the z axis). Please, could some one help me with some clue?

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.
Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).
After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?
