How Do I Unlock Rotation On Iphone 4
Vida Hubbert
Given the case that you can live with delta movements, you can use "quaternion difference" operation. Let's say you have a previous rotation as quaternion called q1 and the current one q2. Then you can calculate the delta dQ between them so that q2 = q1*dQ is valid. All you have to do is build the inverse of q1 (q1^(-1)) and then you get:
If deviceMotionInterval is high enough, you always have handy small Euler angles without any 90 singularities or other beasty stuff. The possible drawback of this solution might be a slight drift because of error propagation and the lack of feedback from your virtual space. Example: if you have your iPhone on a table showing a cube and then do a sequence of rotations, you might find a angular displacment of the cube when you put the phone back in starting position.
EDIT: in reference to your comment above, you can obtain delta movements by registering a handler with -startDeviceMotionUpdatesToQueue:withHandler:. That'll receive a series of CMDeviceMotions, from which you can look at the rotationRate member.
I just solved it! If you open YouTube on your phone, click a random video, make it full screen. It will turn the video so you have to hold your phone sideways. From there, you can access control centre / rotation lock without touching the broken screen part. It moves the control centre to the other side of your phone.
Yes i am using iphone 8. Though its a 4 year old model but still working great and getting ios 16 update. But after ios 16 there is a specific rotation bug with Antutu appoication. I enabled disabled the auto rotation but the app is running with portrait mode and then close in the middle of benchmark test.Dont know how to resolve it
In this context: iOS 16 seems to have introduced a new behavior in which the gyroscopes of many (all?) iPhone models stay on despite the display is being turned off which leads to frequent unexpected screen rotations after unlocking the phone.
I dropped my phone while rotation lock was enabled, and now the right side of my screen doesn't work. Therefore, when I swipe the bottom bar up, I cannot unclick the Rotation lock button, because that side of the screen doesn't work. So, is there another way I can disable this rotation lock, so I can tilt my phone and text sideways at least (because the right half of those buttons don't work either)? (Oh, and I've tried asking siri "Disable Rotation Lock" and it just keeps looking for answers on the web, won't do anything).
I had this problem too, but now I know what to do! You need to open your youtube, and open whatever video, then use your two fingers to make it full screen,your phone will automactilly rotate, then you can slide up your control center to unlock your rotation!!!
I knew the only place to disable the Orientation Lock was the Control Panel. I was just suggesting that if he was going to try Siri to try orientation lock, since that was the proper title, rather than rotation. I didn't have the time to test using Siri. Thanks for the tip.
The Settings app on the iPhone 11 rotates when she rotates the screen, but this is not the case in my iPhone 13 pro, the app doesn't rotate. I have the same settings as hers. Screen rotation is enabled on both phones. Both phones have a 6.1" display.
i updated my phone to iOS 10 on the day of release and I was one of the unfortunate ones who encountered the "Connect to iTunes" bug. Eventually it all got fixed, but now I've got an issue with the phone. Basically I'll open an app or one of the preinstalled apps and when I exit them my home screen rotates by itself. Now I'm a person who keeps my rotation locked and it is locked, but somehow it rotates itself and the only why to reset it is to lock the phone and then unlock it, but when I open something then exit it, it does it again. I've tried rebooting it, but it still happens. Anyone else had the problem or does anyone know how to fix it?
LOL. Apple classic as ever till last decade. Having bugs with their ios then advising their user to reset to factory settings. I have this issue just today so i just googled and found this thread. Oh well, guess I just heck it. The next phone I buy won't be apple again. Having so much bugs with xcode bugs, iphone, even their discussion.apple forum, creating a simple account by pressing the enter key doesn't work LOLOL. Apple is joke! *Guess I better copy and paste what I typed here incase when I click the reply button it doesn't work and my text gone* Lol
You can lock the screen rotation on the iPhone 3GS and 4, running iOS 4, to portrait only by double pressing the Home button (bringing up the task switcher), swiping right to show the media controls and pressing the left most icon (looks like a refresh button), the rotation lock. When locked you will see a padlock in the icon and a new status bar icon of the same design.
This will now lock the rotation in a lanscape orientation! Unfortunately it also disables all hardware buttons, so you will be unable to switch apps, lock the device, or adjust the volume until you triple-click the Home button again to disable Guided Access.
Tried to view my swim activity intervals yesterday by rotating the phone and nothing happened. Tried all other activities and no interval details are viewable for any. Phone rotation is not recognized across the board.
Iphone 6 screen rotation locking randomly after using camera. Portrait Orientation icon not responding. Only way to fix is to reboot. It then happens again after using camera, also effects web browser. Anyone having same problem?
I am having numerous rotation screen malfunctions and I think it may have something to do with the orientation on the home screen getting stuck when I am getting out of the photo app or it could be that I carry the phone upside down in my pocket or bag because the bottom of the apple case isn't protected at all.
I Have an iPhone 6 64GB and I am experiencing all the same issues with the random rotation locking and inverted video picture. I too have checked to make sure he rotation lock option is not selected. toggling it does not correct the problem. Shaking the phone to accentuate the orientation does nothing. The only fix for screen orientation and the inverted video problem is a generally a power recycle.
This is happening with my I phone SE 2020 first generation-- I used to be able to rotate it 180 but can't. I could always to this on my iphone as my plug is only one side. When I need google maps to rotate 180 degrees while still plugged, in a cupholder for example it won't do it and more of my iphone cords are being damaged. I have tried everything online and am competent with tech.
The rotation lock sign logo appears frequently on the screen by itself when Lock Rotation is enabled using the "Use Side Switch To" option on my iPad Air. This lock sign logo appears without the side switch being switched on or off . The already set rotation orientation position is not affected at all when the sign appears, but the frequency of the rotation lock sign appearance suggests there is something wrong somewhere. It has happened so frequently that i was able to get a screen print of one of its occurrences.
Background: Several water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify movement in various joints in the body; however, there appears to be a paucity of research using smartphones to assess thoracic spine movement. Therefore, the aim of this study is to determine the reliability (intra and inter rater) and validity of the iPhone app (Compass) when assessing thoracic spine rotation ROM in healthy individuals.
Methods: A total of thirty participants were recruited for this study. Thoracic spine rotation ROM was measured using both the current clinical gold standard, a universal goniometer (UG) and the Smart Phone Compass app. Intra-rater and inter-rater reliability was determined with a Intraclass Correlation Coefficient (ICC) and associated 95% confidence intervals (CI). Validation of the Compass app in comparison to the UG was measured using Pearson's correlation coefficient and levels of agreement were identified with Bland-Altman plots and 95% limits of agreement.
Conclusion: This study reveals that the iPhone app (Compass) is a reliable tool for measuring thoracic spine rotation which produces greater reproducibility of measurements both within and between raters than a UG. As a significant positive correlation exists between the Compass app and UG, this supports the use of either device in clinical practice as a reliable and valid tool to measure thoracic rotation. Considering the levels of agreement are clinically unacceptable, the devices should not be used interchangeably for initial and follow up measurements.
I was playing music through spotify and when i locked my screen in landscape mode, about 2/3 of the screen was visible. After unlocking and turning it off and on again, the rotation issue was not fixed, but i had portrait mode.
Hi. The problem you describe has been reported several times since iOS 10.1.1. It seems to affect only the iPad Air 2. Restarting the device will definitely fix it, until it happens again. Try turning off Settings > General > Accessibility > Reduce Motion. You can also install a free Clinometer from the app store, and try running it when rotation locks. Please report it here and be sure to mention your iPad Air 2.
