Hi,

Have you checked, Settings/Display & Gestures,Auto-rotate screen is ticked ?

 

Could be the Gyro sensor not working.Have you got a spirit level app ?.

You could try testing the sensor with that.

 

Mine has done this twice, but a reboot normally sorts. If T-Mobile have agreed to send you one straight away, I wonder if they know something we don't?

I hope the issues I'm having with mine aren't the start of something bigger.

 

I just called my vendor, to complain about the auto rotation issue, and here's the step to fix, which worked for me.
Restart the phone, and go to safe mode (restart, and once you see the HTC logo, long press the volume down button), it'll restart again and go into safe mode.
Go to Settings, Display & gestures, G-Sensor Calibration, then calibrate, make sure to put the back of the phone on a level surface, this time, it shows calibration complete not aborted when I did it before in the normal mode.

Restarted the phone and it works fine now.

Thanks,
Mohamed El-Ghazaly

 

Same problem, phone One day old. Internet crashing too.... Why did I bother thinking anything could be better than an iPhone . Think this thing might be going back.... IPhone 4s or 5 me thinks .....

 

Welcome to AF!

Sorry you're experience with the One X hasn't been great so far, if you take it back to wherever you got it from, the retailer may well be able to offer you a replacement. Unfortunately, you can't garauntee every shipped unit is going to be perfect (that counts for all electrical goods), so get a replacement and see what you think, don't be so hasty to give up yet.

 

Whenever the screen sleeps, the rotation resets back to portrait regardless of orientation. This is frustrating when the phone is sitting horizontally on my desk as I have to pick it up and let it know the way it's supposed to be again. Any ideas??

 

I had the exact same problem.

When i tried calibrating the g-sensor it kept aborting the calibration.
After restarting in safe mode, calibration worked and screen turns again automatically.

Thanks for the tip!

 

Hey there! Its been over two weeks since i got the phone
. Yesterday my accelerometer stopped working... AT ALL! Ive tried absl everything, including the safe mode boot, the factory reset and the g calibration. None of these things helped. It cant even rotate the flash video to fullscreen on some pages and it cant rotate the videos from my gallery.

 

My HTC One X had problems with the auto screen rotation. I got it replaced and the new one has been fine so far.

It is a hardware fault. Reboots sometimes fixed it but sometimes the functionality would just come and go at random. My wife's One X has never had a problem, so I went down the replacement route while I still could.

HTC should know about the problem as I reported my issues to them on a couple of occasions and I know other HTC devices have been affected in the same way.

 

I ended up getting mine replaced for this issue.

I had a chat with one of the HTC reps via the HTC website and as soon as I told them what the problem was, they told me to send it in for replacement/repair straight away, so I'm guessing they're very aware of the problem.

 

Just sent my device for a replacement... this is my second time, btw! First it was the display and its yellow spots, and now this... If the new one turns out defective... it will be Quietly Leaving You... And I do hope they replace the unit, instead of fixing mine, cause then ill be cracking like hell...

 

Just wanted to Update.. I was having the same problem even though G-senson calibration was showing complete in Normal Mode.. I restarted it in safe mode and it started working automatically and now it works perfectly even in Normal Mode..

 

Thanks for your help. Instructions are clear and succinct.

Worked perfectly...You should be in tech support

 

Hi Guys!I fallowed all the instruction but nothing worked until I downloaded one of the apps Ultimate Rotation Control from Play Store which has option called force rotation(can also rotate main screen).At the beginning it did not work so I switched back to SAFE MODE and fallowing another tip I disabled Fast Boot in battery settings.Back in Normal Mode phone started rotating almost everything.It took me 4 hours,I tried almost everything and I was more and more convinced that it was hardware problem but not.Only this combination brought G sensor back to life.Now Im more than sure that most of the problems you have are because of software not hardware and do not give up guys just keep on trying and Im sure u will get it going again

 

Dear All wish to be fine my HTC one x status bar doesn't drop down I don't know why, sometimes it is working suddenly and works to drop down few more time then again it stop working. and no Problem in drop down when it is on Landscape(rotation) Please reply me soon???

 

Dear Friend,


It's not Hardware fault also. Don't try flashing or Installing ROMs. Its an unknown error. You can have the solution I mentioned below. Try this friend.


Its an unknown error of HTC one X. I also discovered it. When it was ICS 4.0.3 it was very good. After updating to 4.2.2 Jelly Bean the problem happened. Please follow my instruction that may help you. When you will find your G sensor calibration stopped.

1. Just Disable Auto rotation from Setting--> Display Gestures & Buttons. Or you can disable your Auto Rotation from anywhere you can find in your device setting. Just Uncheck the Auto Rotation.

2. Power Off your HTC one X. Remember No Restart. Just Power Off.

3. Leave it for 10 minutes or 20 Minutes.

4. Now restart and see what is happening. Your G sensor is working or not. You may go to Camera you will find it is Auto rotating. Leave your Auto rotation Setting. Just open the Camera and see Auto rotation is working or not.

5. If it is OK now you can check Auto rotation if you want to open browser in Landscape Mode.

6. If you failed or you have the same problem you just Go to the Power and Uncheck Fast boot and again follow from number 1.

I am confident because that really worked for me. I don't know it will work for you or not. I already told you this is such an unknown Error. May be a conflicting issue with HTC one X tegra Hardware to the JB 4.2.2 Android.

Thank you.
