Good day all,
I have a problem with my nexus 7 (2013)'s auto rotation .It suddenly stopped for no reason. is there a solution for this problem and if I put a custom Rom does it fix this thing??
Please Help
Thanks
Settings / accessibility /auto rotate screen is it checked?
Does it happen everywhere, even in apps? I would check the settings first and maybe try a cold-boot and then a reset on the device.

it does not work even in the games. it doesn't rotate unless an app designed for vertical or horizontal .
I did I factory reset and it didn't work. If you have something tell me what to do please.
Thank you

I had this problem as well a few days ago. What I did (which seemed to fix it) was I went in recovery and wiped my dalvic cache. 3 days since and only time will tell if this is a permanent solution.:fingers-crossed:
Yesterday I had also a rotation problem:
When I set autorotation to "off“, it always went to landscape mode, regardless in which position it was atm. It was absolutely not possible to lock the screen rotation in portrait mode.
After a reboot all was back to normal - strange though!

mine just got the same problem since yesterday! really need help
My rotation isn't working nor is the gyroscope. Started on stock UN rooted , then I rooted it and flashed kangabean and now the latest official CM build and it isn't working on any of those either. I'm thinking mine is hardware and not software related

We'll turns out that my other nexus 7 tab that I got for my mother is having the same issues with the accelerometer and gyroscope like I am. So I am going to be taking both back to bestbuy and either exchanging them or returning them.

Hi,
My Desire's screen rotates perfectly when I rotate the phone from portrait to landscape, with the buttons facing to the right.
However, when I then rotate phone back to portrait, the screen doesn't rotate itself. If I go back to the home screen and launch the app again it displays in portrait mode. This occurs in all applications I've tried (Internet browser, Maps, Mail). I've recalibrated the g-sensor numerous times but this doesn't help.
Has anyone else had this problem? Any suggestions on how to fix it?
Thanks,
Noggin
Unfortunatly (for you) Mine is fine, Looks like it is an isloated incident
Have you Hard Reset your Phone? Might reset the G-Sensor Fully. Sorry I can't be of more help.

Just wanted to post back that killyouridols suggestion of a hard reset solved my problem. Many thanks for the help.

This has happened again and I'm loathe to do another hardware reset. Has anyone else had similar problems?
Hi,
I have the same problem, except it won't rotate from portrait to landscape. Did a factory reset which worked, re installed all previous apps, rotate still worked fine. Battery ran out and turned itself off, charged it overnight, turned it on this morning, and the rotate problem is back, ie no rotation.
Will do another factory reset, but this time I'll be selective over the apps I reinstall in case it has anything to do with one of those - what do you think? Could it be a software issue relating to an app???

Restore to factory default. Make sure you back up contacts to sim and any apps (sign up to AppBrain and sync) etc
Hi, I have the same issue. It started after I calibrated.
I have to shake the device for it to return to portrait mode.
Is this normal?
Fixed mine
I was having the same probem...screen stuck in landscape in certain apps only. I calibrated the phone on a flat surface and now it's fine a first for me!!

I installed paranoid android and then formatted my sd card through recovery CWM and now my screen won't auto rotate at all despite having all options available to auto rotate on. I tried installing viper x 2.0 and reset the calibration and it worked. Installed cm9 again and it was still working. At this point I didn't know it was wiping the sd card that caused the issue so I did it again to get rid of all the left over files from having sense on there and now it won;t auto rotate again. Tried installing viper x 2.0 again and repeating the earlier steps that worked but that isn't working either now. Tried booting into safe mode and doing it there too but still no go....
This was all in a 2 day time period. I'm pretty sure it's not hardware as it stopped working then worked again but now it's not working...
Any ideas anyone? This is very frustrating
EDIT - I installed androsensor and accelerometer, gyrpscope, magnetic field, and orientation all say waiting for event.... Don't really know what that means but thought I would add it in anyway.

I've done some research and there are a fair few people having this same issue using different ROMS but most of them resetting the calibration worked. I can't reset calibration in cm9 or PA because there are no options to.

I think it's ROM issues as well but I've tried cm9 nightlies, paranoid android and viper x and i still can't get it to auto rotate. It was seriously working like last night then I wiped sd card this morning and no go. Man I'm so pissed at myself. Why did I wipe again. Argh. lol.

Hmm, maybe it's not to do with wiping sd card then. I thought maybe it deleted some necessary files for g sensor but I suppose they are probably installed to root directory...
Has anyone else had this happen? If so did they send it back and get fixed? Did you have it unlocked etc???

Couldn't get that work. Wouldn't let me put all numbers in. I'm on cm9 nightly. But I tired again to boot to safe mode. Does cm9 have safe mode? Press up volume until booted.... I still have access to all 3rd part apps though any way its working again. Wtf?

Really, I don't know what you should do at this point.... Probably we are dealing with an HW problem
And now it has stopped working after a reboot. This is so frustrating... Would it be hardware if it cuts in and out? Maybe the sensor is on its way out or something...Only had it for like 5-6 months. If my one x is unlocked will they still do warranty for faulty hardware? Plus I have a cracked screen. Do you think they will look at it under warranty for the sensor?

Just tried the app and can't do a thing with it. Compass doesn't work. Calibrate just tells me to move it in a figure eight motion. Does nothing.
I wonder if they will repair this If the boot loader is unlocked???

When I have a sense rom installed I can do the re calibrate in settings and after I press the calibrate button the little sensor things wobble around and it completes like normal but still doesn't auto rotate and no sensors except light and proximity return values. Games will rotate to landscape then if I quit home screen will be in landscape but then when I lock it and unlock it the home screen goes back to portrait and still doesn't auto rotate.
I got mine through online optus and our local optus store said they would send it away to Sydney and see if they will repair it even though the boot loader is unlocked. Said the worst they could do was say no we won't repair it. Gotta get everything back to stock first and relock boot loader anyway before I send it...
I'm starting to resent this phone
Especially if it is hardware as it wasn't even anything I've done to it myself.... when its working properly though I love it...

Hi,
I have noticed that sometimes the auto screen rotation doesn't work anymore. I have tried to disable and enable again the screen rotation icon but it doesnt help. The only way to restore the screen rotation is to reboot my Note2.
It happens every time after having used a few days my device.
Any idea what could be the reason for this bug?
I am using a stock Rom with root.
Smart rotation is off.

I have installed the app "Ultimate Rotation control" . With this app, I can force applications to rotate but it doesn't

I think but I am not sure that the bug appeared after I have flashed a Perseus Kernel (I see that you have also
a Perseus kernel)
Maybey i found the problem
I maybey found the problem for the screen rotation glich!
I've done my reboots and taking the battery out etc...but after a while the problem kept returning!
Now....i've been wondering around on some forums and i found and read that they have the same issues after the 4.1.2 update!
So.....i tried all the apps on my phone.....exept one!...YOUTUBE!
I have uninstalled youtube and also turned it OFF in the aplication manager!
rebooted my phone!...and gues what?.....my note 2 is running like sunshine and no screen rotation problems! (knock on wood)
Sometimes when you put like a..news app on...some news apps also use Youtube for a movie to show you whats happening wright?
So if you didnt used youtube but did lool at your news app..youtube gets activated without you knowing it!
And then...also yhe screen rotation glitch returned!
Since i put toutube off.....problem GONNE!
But then again.im not a specialist!...im using:
baseband: N7100XXDLK7
Version 4,1,2
Kernel: 3.0.31-679347
I have a unbranded phone!
But ive read on forums that this is a problem for ALL THE NOTE 2's after the update!
Greets and help yourselff

Tick auto display brightness and it will rotate!
I too got the same problem some times back. And along with that the network was also not getting detected. Some of my friend told that the network IS is gone. But I went to the service station and the software up gradation makes it alright.

Did we ever figure out a real fix for this? Was the true cause of the problem ever even isolated? I am aware of the "auto brightness trick", but have also heard about fumbling around with the multi window feature or opening the dialer to "unlock" it.

Hi guys
Im very happy so far with the Note2 I think when you get used to the size is the best android phone (not for long I know )
However I can't strees how annoyed I am with the Autorotate BUG
every other day i need to restart the phone because it would not rotate.
does any one know a way to fix , or have a better solution than restart the phone?
Many thanks to all who read this
Um..disable Smart Rotation in Display Settings, and Uncheck and Recheck Auto-rotate Screen, Make sure Auto-rotate is enabled in your Notifications Area. I had this bug in very Galaxy S phone so far, guess its Android's way of saying Root! :laugh:

How does rooting solve this issue?
I have a similar issue but it rotates when I place the phone down to a flat desk or surface.
i'm on Monxdified rom previously & rooted ..
the issue still persists ... so root wont solve the issue
That confirms it is indeed, an Android bug, nothing you can do about it unless you e-mail Samsung and Google.
What bug is this? I haven't had it, or haven't noticed it yet. I use smart stay, but not smart rotation. How can I reproduce this bug?

My GT - N7105 (i like to add the preceding GT thinghy lol)
I don't think is a Android problem of all my different android devices this is the one giving me trouble
is nothing to do with root, my phone is rooted and im using this [GT-N7105]N7105XXDLL4 deodexed Rom V1.1 [4.1.2]
I was not sure if is a problem of the ROM itself or in general that way i put in there.. is anyone having that trouble?
thanks
Hey guys!
I have exactly the same problem with my N7100 running the N7100XXDMC3. The issue came up the day after I bought my phone. I've rooted it, flashed the last firmware and did a format system and wipe cache, data foactory and dalvik cache. The bug still persists.
I've written an email to Samsung they told me to do the update and wipe the datas (What I've already done). They told me if the bug is still present to bring the phone back.
Have you resolved the bug ? Please help me because it's very annoying :/
Mine does the same and I have exhanged one unit because of it and still happens its weird wished samsung would fix it. Only seems to happen when I watch a video for long period of times. Dont have smart rotation enabled either
I've got the solution ! Well it's not the solution but a solution. Download the app rotation lock adaptive. It fixes the bug and even allows to get a total rotation. I bought the app to thank the developer but a free version also exists.

Reset the phone always works...and so does reboot the phone...the bug returns in a few days. am on the most recent ME1 update for the N7100 but the issue persists...its not an issue with the launcher, root orkernel related...I tried all the combinations ...
I noticed this after updating to 4.1.2.
Looking around the web this update seems to be the culprit. Mine gets stuck in landscape mode every two days or so, however launching the stock dialer fix the issue.

I have had the same problem on my N7105 since the 4.1.2 android update.
I realised that the bug occurs only when brightness is set to manual.
I did the following to fix it:
1. I installed Velis Auto Brightness app
2. I run the app setup wizard with default options
3. I set the note 2 brightness to auto (this has no effect anyway because Velis override it)
4. I restarted the phone
5. I selected my preferred auto brightness profile through Velis
My phone's auto rotate now works perfectly!
I hope this works for you as well!
I just got the Tab S 8.4 yesterday and I am trying to figure if I am missing something. My screen will not rotate, it will stay in portrait mode all the time, it will not go to landscape mode on anything...youtube, internet, gallery, etc. Yes...the SCREEN ROTATION is on in settings. I have turned it on and off and still nothing. I even went ahead and did a reset. Still nothing.
Am I missing something?
Probably not, just need to return it. Something might be wrong with its hardware or software that will not make the screen rotate.
Is screen rotation highlighted when you pull down the notification panel? If it is download SENSOR BOX FOR ANDROID from play and see if the orientation sensor is working.

Screen Rotation is highlighted when I pull down the notification panel. I will download the app and check it out. I mean, what can I do anyways if it does show that the sensor is working correctly?

at least you will know the hardware is working. You could also try SET ORIENTATION from play to see if you can force it.

Set orientation did work. It did change the orientation of the screen from portrait to landscape. But it stood that way, meaning everything was either going to be stuck in portrait mode or landscape.
As for the launcher...its stock touchwiz. I have not tried any other launchers.

Ok, I downloaded app and no good. The gyroscope sensor did not move correctly. The accelerometer sensor showed me the worse. The ball just rolled to the top right corner and stood there. Did not move at all, even when I slam down on any direction. Returning this tablet.

I bought an Open Box for about $90 off from Best Buy, the 10.5 Tab S, and had the same issue with no rotation of screen. I only tested it with other programs that will change orientation for you, and it worked then, but not automatically, only when using the app. I checked all settings, including accessibility, I flushed the cache using the Recovery mode, but no luck. I did get lucky though at Best Buy, as they were awesome and ended up giving me a brand new one in exchange, without any additional charge. There may be some manufacturing defects in the sensors that are causing these issues. Good luck to you too sir.
Ive seen it said that some people, who've had the same problem, gave the tablet a sharp slap on the back to fix it.

i know this thread is 1 year old however i purchased a brand new S2 8 inch tablet from canada computers and it too will not rotate the screen on its own. If i use a 3rd party software it has no issues rotating but it stays that way until i rotate it otherwise manually. Brand new less than 1 day old and i already have to warranty it with Samsung disappointed that such a premium tablet having an issue out of the box. Also all sensor software in install all indicate there are no sensors installed.
Edit: ok now everything works great and all sensors work now on Sensor Box. I had to do a hard cache reset of the cache partition using that dos look alike menu at startup.

This confuses me since the Android settings Backup / Restore has "Factory Reset" which I did twice and it didn't work, then I pressed power button, volume up and home button to bring up the other menu on bootup and selected the format cache partition option. This resolved the issue and was happy I didn't loose my data unlike the backup/restore had wiped all my data. Is that still considered a factory reset? I did see the option to factory reset but didn't select it, I opted to try the cache partition instead which I was glad had worked. Saved me from taking my new unit back to be repaired.
theres an app called bubble level (spirit level) i used to re-calibrate my sensor since there isn't a built in way anymore, if the slapping doesn't work or you don't wanna risk it try that.
