[Q] Calibrate Gyrometer?

I just picked up the GNex Friday and have noticed sometimes the screen doesn't rotate properly. I thought nothing of it until this morning when I had to shake it a few times to come out of portrait mode. I then went on to play some Raging Thunder (car racing game), and my car just makes hard lefts and crashes.
So I'm thinking there is something up with my gyrometer. I downloaded "Gyro 2D Visualizer" and can can confirm that the phone is off quite a bit.
Here is a picture of it on a flat surface, you can see how much it's off:

"lightbox_download": "Download",
"lightbox_share": "Share",

"lightbox_new_window": "New window",

}
Anyone else have this issue? Is this bad hardware or is there a fix?
Thanks!

After your post I went to take a look with GPS Status and you were right. It's a bit off. I calibrated it right away and should be correct now.
Weird they did not add a calibrator in ICS.

Would you mind sharing how you calibrated? I have GPS Status, but I'm not sure what it wants me to do when it says "rotate your device 1-2 times around each of its 3 axes".
Also can you verify that your calibration remains after a reboot?

What you're talking about is the compass caibration. Do the following
end over end (flip); hold it with the screen up and flip it away from you making a full rotation
side over side (roll); hold it with the screen up and move it from left to right so the screen rotates left, down, up right
screen-up rotation (spin); put it on a table and spin it around

The 2nd one is putting your phone on the table and the pressing calibration.
Hope this helps

Ah ok, sorry for the confusion. I found the other option for "pitch and roll".
Unfortunately, loading the game yielded the same results. I tried to play Doodle Jump and I had to tilt the phone to the left to get him to bounce straight up and down.

I downloaded the gps status app and mine seemed right on, however does anyone know if this app also shows you what the barometer is reading?

[Q] LCD not displaying

Hi there,
My phone is semi-bricked, that is, when I boot, after the Sony Ericsson logo there's nothing except a gray-black screen
(like this one:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What I've done before:
Flashed http://forum.xda-developers.com/showthread.php?t=1595058
I was using this rom for about 3 weeks and everything was fine. Two days ago while playing Plok! on Snesoid the phone froze(the gray-black screen popped up). I rebooted(had to take out my battery) and everything was fine. Yesterday while playing "Gravity Defied" the phone froze again. I rebooted again but now I get this gray-black screen right after the SE logo. Recovery doesn't work. I tried to flash the rom from the above link again but it gave nothing. I flashed 4.0.2.A.0.62 from here: http://forum.xda-developers.com/showthread.php?t=1589399 and the same problem still occurs.
Is there any way to repair it on my own or do I have to go to a service center?
update: I kept the phone on with this gray-black screen and after about 30 minutes the screen changed to normal Android "desktop". Any idea what's going on?
update2: Maybe that's important -> when the previous 2 freezes occurred I had the PS buttons slide extended. I have played some games in the meantime with the phone slide closed and everything was fine.
Update3: It's definitely not a software problem. If the slide is closed everything is fine. After I extend the slide, the screen stops to refresh(the touch screen works, I can pick up calls etc. when the screen is gray-black). When I close it back it takes some time for the screen to work again. My guess is that's a problem with the ribbon cord but I've no idea what can I do with it...any suggestions?

try flash to original firmware

Its the flex cable. Its what connects your display to the gpu.

Warranty is void when you open the bootloader.

Partial "crashed" screen for a split second - soft- or hardware issue?

I've been using my One X for several weeks now (I think the hboot date is around early June so it's not one of the early batches) and so far didn't have any problem except for the following:
Twice, first a few weeks ago and the second time last night I saw some "artifacts". I'm not quite sure but I think different parts of the screen were affected each time. What happens is that everything is shown how it's supposed to be except for a 30%-40% area which looks a little like a computer screen right after a software/driver crash can look like. Without doing anything, it disappeared each time after less than a second.
I wasn't able to take a screenshot but the following photo shows how it roughly looked like. In my case, there were only lines and cubes in black, white and bright green instead of the more "fuzzy" parts shown in the photo.

Is this a driver issue? A lose connection? A display fault? I was close to unlocking my phone but with this having happened twice so far I wonder whether I should wait a little longer...
PS: It's probably unrelated, but like a minute later I encountered some "keypad ghosting" via swiftkey, i.e. I was pressing some keys on the keyboard and it was inserting several different ones each time. I do suppose that it's a software glitch, though, as I tried the stock keyboard another minute later and this worked fine.

If you can still swap your device with your retailer I would do that, just to be on the save side...

did u update to latest already?
if yes,
was it there before u updated..??
it doesn't look like a hardware issue

Did it act like this: http://www.youtube.com/watch?v=HIY0_Hy2_mA ?

No, everything was where it was supposed to be and the artifacts faded away after probably less than a second.
I still have the latest stock Rom, haven't updated yet. I do think it's been more of a software glitch but I couldn't find information on here or anywhere else which would state a similar problem. Which is good?

[Q] Galaxy Note 2 goes into Silent Automatically

This is driving me mad.
My new Galaxy Note 2 randomly goes onto Silent mode. I thought it might be to do with motion so I switch all the settings off. Also there are two settings in display regarding motion and I've switched those off as well.
Still it goes randomly into Silent when I get back to the phone.
Anyone else having this problem or could it be a rougue app doing this?
I have read people complaining about this on the S3.
Thanks
Anis

Long shot, but... Did you check "lock mode" in settings?

Switch off your block mode if it is on in settings.

I think this is a builtin fault of system and it is with android since ICS

Thanks for the replies:
1) Don't know what you mean by Lock Mode?
2) Block mode is definitely not set.
It just did it again.

Sorry. My phone's language is Portuguese and I had to make a guess at the English equivalent. It is probably "block" as leony74 said. 6th entry on the Settings menu.

Sorry folks, I think it was my fault.
My Islamic prayer time app automatically put the phone in silent at prayer time.
Well, I am 99% certain it was this anyway.
I'll report back if it still is going into silent.
Thanks for all your help.

Exactly, Salati app was doing the trick, and the image confirm your theory.

Thanks for your reply, the problem was caused by our prayer app (Muslim prayers) so it turns the phone silent for praying time, i disabled it because sometimes i am not in the mosque so i need my phone on.

I finally found one of the possible reasons! It was avg antivirus app that was causing same problem in my note 2. Try uninstalling avg antivirus. It worked for my phone

Lock screen rotation bug

My wife and I both have a GN2. Mine is running MyRom and she is completely stock (no root or anything).
She has a problem with the lock screen. Sometimes it will try to display in horizontal mode when the phone is being held in portrait orientation. This causes the lock screen pattern to be cut off.
I have never had this happen on my phone but she had to get her phone replaced (different reason) and it did it on both phones. She has to restart her phone to be able to unlock it.
I tried to mock up what it is doing but my artistic skill is lacking...

I wish I could screen shot because I've experienced the same. But I still just swipe up to unlock and it works just fine. You know how on nexus services the jelly bean clock where the hours and minutes are a different font abs one is bold over another is a description of how the display looks

Check her rotation settings, smart rotation and all. Im sure u already did that and it made no difference but its always the first thing to do.
From my experience whenever thst happens its because of excessive background apps are open killing the processor. Does she kill apps at all? Restarts the phone from time to time? Tell her to kill apps instead of backing out, hold the home button and the right buttin should kill the background apps and thr left bitton will take u to the ram and frees that up by clicking another button.
You can also download advanced mobile care on the phones and it has an option to kill apps when the screen wakes up, slight delay before input, bit it kills background and app processes. Good luck and report bavk
