Does the epic have a gyroscope?
Just wondering and is there a way to test it?
Thanks

The epic and all galaxy s variants have a six axis gyroscope

In the market there is a free app called Z-Device Test, it tests many things on your phone including the accelerometers/gyroscopes

Just downloaded and ran that app, and it only seemed to see the accelerometer (no mention of a gyro in it).

Fyi, the Epic 4G has a six-axis sensor, which is really a 3-axis accelerometer (for up/down, left/right/ forward/backward) and a 3-axis gyroscope (for "twisting" the phone in each of the 3 planes).

multi touch fix for desire?

Hey guys wondering all these Rom makers or Google/htc made any multi touch fix?
With all the custom kernels and open source roms, has any developer attempted to fix this issue?
Would like to play games without on screen keyboard issues due to multi touch, this also affects typing fast.
Thanks
Hardware not software please do some research
Thanks. So does the s-lcd have the same issues?

the type of screen does not make a difference its the bit that lets the phone detect touch that is the issue here.
All HTC devices detect only one touch, and then detect the "size" of that touch which allows it to have pinch zoom when it detects a change in the size.
It cannot detect 2 individual touches.
please delete

Wait a minute, the Desire does have a basic multi touch digitiser... pinch to zoom in the browser etc. proves this. The EVO guys have developed a multi touch keyboard fix btw

you obviously didn't read what I just posted then.
It cannot touch 2 different touches at one, it detects one LARGE touch when two fingers are on, and then when you "pinch" it detects the size of that LARGE touch getting bugger or smaller.
Search for "Multitouch Visible Test" in the market.
That is an app for displaying the detected finger touches.

the desire dosent have multi touch, but dual touch instead, the issues people are having with games is beacause the desire gets confused When two fingers are placed close to each other or they cross the same axis because the data points get flipped, this is because of the way dual touch works, When you touch the screen with two fingers one by one, you get three points of reference: 1) Fixed Point – location of first finger, 2) Real Point – hardware detection point when two fingers are placed and 3) Fake Point – location of second finger. Interestingly, the hardware does not ‘know’ about this position – instead it is calculated by the application.
Is this translated in a hardware level or just driver?

I loaded the page a long time before you replied and only saw your reply after I had submitted mine. I edited my post immediately after seeing yours.

ok then, sorry
And as mentioned you are wrong, as the desire do detect 2 points/fingers. Any multitouch test app from the market will show that.

no, what we have said is correct, the apps show an output but its not true multitouch.
All you have to do is try any multitouch app and do a google search to see all deivces up until now (after desire) made by HTC have dual touch, not multitouch
basically speaking it can detect certain multitouch gestures but not everything.
well i can play sonic and a load of other games and snesoid on the genisoid with run and jump buttons together, which tells me it's at least dual touch, to be honest the screen isnt really big enough to get 3 or 4 fingers on it properly and see what you are doing anyway
I will record a video of the hardware limitation of the touchscreen in HTC Desire.

or just search on youtube, loads have been done already.
I am not on about the lack of multitouch, there is a bug with two points with two near x, or y, axis points; they join together for some strange reason.
Link to video: http://www.youtube.com/watch?v=noQBUDy-WCQ
This is why multitouch keyboards dont work and there are problems with the PSX4droid emulator when having both dpad and control buttons on top or both on bottom.
I read somewhere that there was code in Android for a that filtered the Droid's multitouch results, that results in the Droid not having the axis flipping issue (does still have the sticking issue when close). Is there any way this code can be implemented on the Desire?
I think a developer called Phhusion on the Acer liquid forum in Modaco solved this software wise.

as far as I know that games uses accelerometer non gyro.

I would like something graphical that shows me the movement of the gyro instead of the "raw" numbers.

hmmm, my gyroscope moves when the phone is sitting on the desk.

The cube rotates only a few with my phone, I'm not able to rotate it completely.
is this normal?
Sensor track shows a live graph with three lines for the three dimensions.

Sensor Calibration

Hey,
can anyone tell me how to calibrate the G-Sensor in the Gaaxy Nexus Prime? In games and apps using this sensor it seems that the y-axis is about 5 degrees leftside when i hold the smartphone straight up. This means for example that the figure in doodle jump moves slowly left, although the Nexus is holded erect...
Googled for an solution by myself, but nothing helped so far. Even apps like BubbleLevel, which have the calibration tool, calibrate the sensor just for this app... and not in general.
Thanks
Try calibrating with this app and see if it helps.

Ignore everyone telling you to use an app to do it, because you can't. Android has no concept of global calibration regarding the sensors.
I have 3 Android phones, they all have wrong default calibration, from a few degrees (Galaxy Nexus) to about 30 degrees (Xperia X10 Mini Pro.. unusable).
You used to be able to calibrate in gingerbread by modding axis offset values in the AK8973Prms.txt file in data/misc. ICS doesn't seen to have that file, at least not in the same place.
HTC Desire, Desire HD have its calibration app.

He asked for help and I tried to help him with what work for me in the past. No need to tell him to ignore people. It's a simple process that involves rotating the phone on 3 of its axis. If it helps, then great. But it certainly wouldn't hurt for him to try, would it? No need to be condescending; it's not like I'm trying cause him harm.

I think that method works well for compass calibration for apps like maps and sky, but it is temporary and doesn't seem to affect pitch and roll. GPS status let's you calibrate pitch and roll but only within the app, it doesn't affect system calibration. The file i mentioned above did allow manual system calibration under gingerbread. Not sure how to accomplish under ics. A post i saw suggested that gnex and ics automatically calibrate if you leave the unit to sit alone for a bit. I don't buy it, but that's the only info i have found.
In case anyone is interested in how it was done under gingerbread, see my post at http://forum.xda-developers.com/showthread.php?p=16592139

It's not Gingerbread, it's for that specific sensor with that specific driver. The Galaxy Nexus uses a Bosch BMA250 which has an NV memory where calibration settings can be stored but doing so is not trivial.

How to solve proximity sensor issue

I recently had an issue regarding the proximity sensor on my DHD and I tried many different ROMs and calibration apps but none of them worked. Seems like the problem is the dirt that blocks the way of the sensor. I cleaned the grill from the dirt and everything is now OK. Hope I helped someone.

Hi have you tested the proximity calibrator app?
Setup of proximity sensor isnt the main goal of roms...
Look at this thread http://forum.xda-developers.com/showthread.php?t=951858
Set values, test it if the sensor shows "near" or "far" or adjust it more.
My DHD needs LOW = 2; HIGH = 3; and it works...
oh , and in Cyanogenmod 11 by mustaavalkosta, its already installed i think.

Yep spot on. CM11 comes with it.
Low 3 and High 5 works best for me.

That's what I had to do in the end as well. Remember that these phones first came out in Oct. 2010 (when I got mine ....!!) so plenty of time for dirt to build up. Check the Proximity Sensor thread for links on disassembly but I followed this site ... http://www.beardeddonkey.com/home/comments.php?y=12&m=04&entry=entry120428-040327 ... to take mine apart. Not all of it, just far enough to clean out the PS. All good after that.
thanks for the tip
i need clean my sensor
thanks man !! been modifying thresholds using Proximity Recalibrator forever with no avail ... i don't know how i forgot about cleaning the sensors :silly: :silly: you made my day !! thank you a bunch !!!!

Compass Not Working

Does anyone know of a setting or anything that would keep the compass from working? I've tried doing a hard reset twice now and it still won't work. I may try returning it and getting another watch if I can't get it to work.
There is no compass.

I swear I used to be able to use a watch face with a compass and it would work just fine. Also would work with compass apps on the phone.

Can confirm, there is really no compass. No use in getting the watch replaced.
Which watchface were you using?
Dark suite and classic watch faces have compass. You guys are silly hehehehe
