[Q] Accelerometer Problem w/ Tab 7.7 - Galaxy Tab 7.7 General

Help! I just got this tablet today and was using just fine out of the box.
I went into Settings> Screen to make sure Auto-rotate screen was checked - OK
then went to Settings>Motion to make sure Motion activation was checked- OK
then went to Settings>Screen>Horizontal calibration
I placed the device on its side, i.e., landscape mode, on a flat level surface and hit Calibrate. It went through the calibration function.
Now when I use the tablet it does not flip the screen from landscape to portrait.
I did a factory reset and still have the same issue. No screen flip , the landscape mode is the only postion it will flip in and it does a 360 degree flip right back to landscape.
Bad/defective accelerometer? or is this just some setting I am missing or need to reset/calibrate.
Any help would be appreciate as this is a p6810 WiFi only Hong Kong tablet.

just an idea, try recalibrate with tab flat on a surface ( not on its side)

That worked!! Thanks mate! Samsung customer service had me try to calibrate it by ME moving the device to get the ball on target! I did as you said and the ball was off target and it centered itself during the calibration...
I am back up and running again! Flipping like normal now.

Craziest Screen Problems

Hey guys... I'm having a lot of troubles with the lcd screen on my 8525 and this start about a month ago.. I've had this phone for almost one year... bought it as a refurb.
1. when i'm using the phone portrait mode the screen alignment would be perfect... however when i slide the keyboard open the screen goes to landscape and my alignment would be completely off. Heres the interesting part... say if it is still in landscape and i align it then.. it would work perfectly in landscape but then when i close the keyboard and go back to portrait the alignment would be extremely off again.
2. now when i'm in portrait mode and i go to start -> settings -> system -> screen and switch the screen to landscape (w.o sliding the keyboard open) the screen would be perfectly aligned... but when i slide the keyboard open... the alignment would be completely off again... now if i align it while it is in landscape (keyboard open) and go to start..settings..system..screen and change it to portrait the alignment would be perfect... but when i close the keyboard.... it would be off again...
is there anyway i can fix this? I've done a hard reset and flashed the firmware all over again... btw i'm using WM6 from the htc website. if anyone can help...lemme know what i have to do....
thankz
p.s my phones starts with s/n ht649.
Can't say I've seen that reported before. Sounds software based. You could try backing up and hard resetting.
Mike
I already tried that.. it didn't work.
Sorry, my bad - you clearly said you had done that already.
I can't fathom what hardware problem there could be. The magnet orientation switch is clearly fine it seems the X Y co-ords are not swapping over - but that seems a software matter, yet your hard reset suggests hardware - Im stumped.
Mike
If the whole screen is moving, including the start menu etc,
I have seen this before, when building my phone, if the lcd ribbon cable is not alligned perfectly this can occur... but resetting the device did not resolve the issue in this instance.
Cheers
Steve
So I guess I'll have to take it to a cellphone repair shop and have it looked at. I just hope it won't cost too much... the phone was a refurb and i got it for $100. Do you guys have any other suggestions?

Dissasembly, screen rotate broken

I recently replaced the screen in my 6800 - (I'm out of insurance replacements, and I don't like the Touch Pro Verizon offered me very much.)
The dissasembly and re-assembly went swimmingly - except for the fact that my phone now reverts to Landscape every time it wakes up, as if the switch that detects the sliding motion is broken or disconnected.
Does anyone have any details of where this switch is and how it works? I have heard mention of it being a magnetic reed switch, but I also see a little tab of metal in the slide mechanism that looks like a contact closure point for this.
Any ideas or information?
I know this isn't probably the best answer, but have you looked into software that will rotate the screen? You could then assign that software to a button and rotate that way.
Yeah, I have "Screen Rotate" mapped to the messaging button, but it still reverts to landscape every time the phone goes to sleep, even if I set the screen mode to "portrait" in the settings.
I took it apart all the way again last night, I still can't find any sign of the mechanism it uses to detect open/close.
There are some metal ground clips on the lcd side that I think it uses to sense its location. If you slide the phone out you will see a gold colored clip in one of the slide groves.

Accelerometer problem or is it?

I droped my phone but it was inside a big protective case now i don't know if this issue is related to this but here it goes.
If i open a picture message with the phone in my hand the screen goes into landscape, when i exit out it stays in landscape until i exit the messaging client. Here is the strange part, if i leave my phone flat on the table and do the same it goes back to portrait mode as soon as i close the picture.
Does this sound like the phone has a hardware damage?
Tried restarting it and calibrating the accelerometer, nothing.
Can someone please also do me a favor and see if in the game Teeter when the phone is on the flat surface does the ball still rolls slightly to the left? I can make it stop and not move but it prefers to go to the left.
My ball stays still.
I don't see how this can be a problem since accelerometer works but in an sms client only when the phone is on the desk.

Problem with Auto rotate

I just got my note and am having problems with auto rotate.
I ran the tests in *#0*#
It looks like they all passed fine
But sometimes mine rotates n it's own and when it rotates, it sticks in Horizontal.
I do not understand the calibration instructions for Horizontal and Gyroscope.
For instance, when it says place device on a level surface and press calibrate, does that mean just place it on it's back on a table? Also, after it is done calibrating, should the gyroscope "ball" on that page move when you move the device? Mine is always stationary.
On the horizontal calibration, how do you position the device before you hit the calibrate button? Should it be landscape or portrait?
IMO they don't explain these very well and it's confusing how to set this up.
Yes, just place it on a table or the floor. Not sure with the gyroscope since i don't have the Note yet, but i imagine the ball moves.
If this is a bug it's a software bug. All Desire HD owners including me had the auto rotate bug when it got released. These are bugs that's very common on freshly released Android devices, and it will get fixed.

Here's the question I have:
I only have 30 days for return if it's broken. Nobody else has complained about auto rotate yet and I would think that would come out pretty fast. I figured out mine had a problem 30 seconds out of the box.
Hi les_garten (another maemo/TMO refugee here!) - I've had my note for over a week, haven't seen any spontaneous rotations at all. I calibrated my gyro on day 1 though I think you don't ned to unless you are having problems. Once calibrated, the blue ball just sits in the centre of the circles, it doesn't move at all.

Thanx for that info! Mine also rotates when I turn horizontal, then won't go back into portrait.
How do you do the Horizontal calibration. Do you stand it on it's edge in landscape mode?
I'll never give Nokia another Nickel! Great idea with dismal execution.
horizontal calibration just involves sitting it flat on a flat surface. After calibration the ball can be "rolled" across both axes - like I said above, for me at least the gyro calibration screen does not allow the ball to roll at all either before or after calibration (hope that's what's supposed to happen, I've never had a phone with a gyro before, I would have assumed the ball was meant to move in response to tilt/turn ....

if you go into the dialer and dial *#0*#
then do sensors and run the Gyro tests and graph, it seems to be fine.
I have to keep auto rotate off.
It will rotate Landscape, but won't return to portrait.
It wil flip Landscape on one side and Landscapeon the other side, but won't do portrait, till auto rotate is turned off.
Anybody have any suggestions on how to fix this?
I guess I could whack it and start over, but that blows! That would at least tell me something I guess.
It's really irritating. And I would hate to keep it if it is broke.
I have the auto rotate bug also...you need to try many times before it will rotate... kind of embarrsing.. but I am sure it will be fixed first..but sometimes I wonder..if samsung have tired the phone at all before they ship it...such fundamental feature should work...without any problems

For some strange reason this makes me feel better!
bug was solved in 2.3.6 ..works without problems now.

Thanx. I just did mine last night as well.
Very happy now!
i just got a galaxy note 3 weeks ago and it is running gingerbread 2.3.6
i have the same problem for the auto rotation problem, when i test the gyro and horizontal calibration, the ball doesnt move or move in a very laggy motion, when i lever my phone to a certain angle in all direction, the ball will not move in some area of the display. i had calibrated once before it has this problem, the ball move smoothly in any angle...now my message will auto rotate to landscape while i holding it in potrait...please help
I can't actually help fix anything - but if you enter *#0*# in the dialer and then select "sensor" from the LCD tests, then "image test" (under accelerometer sensor) you'll get a picture of a dog whichshould rotate between portrait & landscape as you rotate the phone, and there is an overlayed real time display of x and y axis angles as registered by the accelerometer.
This test should at least show whether the h/w is working or not.
Fix here

I can fix that.This is from galaxy S2 but i dont knows how for Note, i try and working for Note. But after install from CWM, i see Setting/Display/ Gyroscope calibrationand Horizontal calibration. It not working. I was very afraid and i flash new rom N7000ZSLPF---------4.0.3 http://hotfile.com/dl/156123968/e690f65/N7000ZSLPF_N7000OZSLPF_OZS.zip.html
And now Gyroscope not work but rotation is work good.
Sorry my English

[Q] Accelerometer problem

When I flash a ROM (ie Jelly Blast) on my S5360T, it makes the accelerometer act all weird. Turning the device to the right makes it flip to the left side and turning it there puts it into portrait. Turning it to portrait turns it back to landscape (in the right) again! Is it because of my ROM or an actual problem with the hardware? Please tell me if it can be fixed and, if yes, how.
Sorry if I is a noob...

you gotta check accelerometer calibration setting.go to calibration setting. place phone a leveled horizontol surface and then press calibrate...it must work.

Hmm it doesnt work....... Hmmmmmmm
Is...
couldn't there be an app for rooted phone that allows better clibration than the original default, because i am stuck with the same problem your having
just go to settings>display>callibration>and callibrate it.
make sure its on plane surface like a tabletop or something...
sometimes it happens because of the data reset..(as beleived by me)..
rooting is new for me...and i am noob to root...
