It’s not just the iPhone 5S — the 5C sensors aren’t accurate either
- aw3c2 13y agoIn Android one can simply calibrate those sensors by placing the device on a level surface. Surely this is possible in Ios too?
- ghshephard 13y agoApple has a calibration process that doesn't require a flat surface. The first time you go to the "level" app (it's a right swipe from compass) - you are asked to spin a little virtual ball in a circle (kind of like a roulette wheel) - after three or four spins it's calibrated and (at least on my iPhone 5) works as a dead level.

- hmottestad 13y agoI'm leaning towards a calibration issue. Apple could release an app for calibrating the sensors and offer to help you at an Apple Store. Anyone familiar with Windows Phone or Android know if their sensor software offers calibration?
- Osmium 13y ago> I'm leaning towards a calibration issue. Surely this is easy to test? Is the level always off by the same magnitude, in the same direction, for any given phone? Would be nice if the parent article had tested this... If a particular phone is always off by, say, 3.5º it's presumably an easy fix, though, as you say, would require everyone to run a calibration on their phone.
- hmottestad 13y agoIf every phone has a slightly different offset = not calibrated A batch of phones has the same offset, but there are different offset between batches = calibrated, but poorly All phones have the same offset = Rounding error, sensor bugs, who knows.
- arrrg 13y agoIt seems like my 5S is consistently off by the same amount (about 3°) in the same direction. Seems to me like a software fix will be possible. I have two years warranty, so I’m not too worried at this point, only slightly annoyed.
- raverbashing 13y ago" if their sensor software offers calibration" Yes, level apps on the Android offer calibration. Without that, it's worse than the values shown from these iPhones This can be solved by maybe better software and calibration. It looks like not a big issue
- hmottestad 13y agoI meant system-wide calibration. Any app can offer it's own calibration and many iOS games have options for the user to calibrate.
- marban 13y agoHow can 2.7° even matter? I assume people are not laying brick walls with their phone.
- adlpz 13y agoAre you serious? If you are hanging a 1.5-meter long painting and you go off by 2.7 degrees (not %, by the way, that would be FAR worse) on the angle, one side will be around 7 centimetres higher that the other. This is a serious screw up. Hopefully it can be solved with just a recalibration.
- marban 13y agoI can do the maths. We're not talking about the precision of a measurement tool here but mostly a mediocre input controller for asphalt racing, which I assume is barely noticeable for people playing a game on their couch.
- stedaniels 13y agoUnfortunately, your narrow view of the use of the sensors in a smartphone isn't indicative of their actual widespread use in many applications hobby and commercial. Heck I remember reading recently about some of the Syrian "rebels" using an iPad to aim mortars. (Note my example isn't something I'd entertain personally!)
- Tyrannosaurs 13y agoGenuine question - what is the stated accuracy of the gyros? Surely that's more important than what people choose (potentially ill advisedly?) to use them for?

- Hopka 13y agoI'm sceptical. You can actually use the upper button on the left side of the app pictured in the article [1] to calibrate that app. So you could make it show whatever inaccuracies you wanted. And it's far from an "unfixable sensor problem" that "would put a dent in Apple's reputation". Also, analog bubble levels aren't always perfectly accurate either.

- MattBearman 13y agoThe relevant info from the link above: * IMPORTANT MESSAGE. PLEASE READ * Because the sensor inside every individual iPhone/iPod touch could be built slightly differently, to make the level more accurate for your device, you need to calibrate before use. To calibrate: 1. Find a flat surface. 2. Hold your device upright (in portrait mode and home button at the bottom), put the bottom edge of the device on the flat surface, then press Calibrate button (the one with a target image on it) to calibrate the portrait mode. 3. Turn your device 90 degree clockwise (now it should be in landscape mode and home button on the left hand side), again keep it upright, and put the current bottom edge (long edge) on the flat surface, then press Calibrate button to calibrate the landscape mode. 4. Put the back of the device against the surface, then press Calibration button to calibrate the face-up mode 5. You are ready to go!
- arrrg 13y agoApple’s built-in compass (which has not calibration) also shows many devices to be off. I’m not sure why that person chose a third-party app to show this off. This is a real issue.
- andyhmltn 13y agoAFAIK you can calibrate the compass. At least in iOS7. But using an iPhone 5 I always find the compass to be incorrect most of the time.
- kalleboo 13y agoAccording to users in the thread about this on macrumors, the error isn't linear, and if you calibrate it, you still get inaccurate readings once it's off-level. > The issue is that it cannot be calibrated out. I've tried, > it can't be done. You can zero it in one orientation but then > the error is doubled in the opposite orientation.
- static_typed 13y agoHas QA slipped, or are all the walls in walled garden all a bit wonky?
- leviathan 13y agoI'm wondering the same thing. There's also this placeholder text that still shows even on iOS 7.0.2 https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-prn2/q71/s720x720/1381839_10153347469130121_1218956929_n.jpg https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-prn2/q71/s... I submitted a bug report, but I'm yet to hear anything about it.
- dan1234 13y agoThat's odd. The placeholder text doesn't show for me (correctly reads "Music"). iPhone 5/7.0.2
- leviathan 13y agoI checked with 4 separate phones with 4 separate people. Same thing. Maybe it's a localization issue?
- yardie 13y agoI have a iPhone4, iPad2, and iPhone5, on 7.0.2 and a 4S still on 6.1.3. I'm not getting the placeholder text at all. Did you update from a beta?

- kineticfocus 13y agoTo their credit it's probably related to a recently added feature... http://www.technologyreview.com/news/519531/what-apples-m7-motion-sensing-chip-could-do/ http://www.technologyreview.com/news/519531/what-apples-m7-m...

- linker3000 13y agoOh dear, I've upset the fanbois! Antennagate Magsafe power adaptor recall Scratchgate/Scuffing Maps There's no doubt many companies/products have glitches and design faults, but the eulogizing needed a bit of balance.
- ScottWhigham 13y agoMy guess would be that people downvoted you for your reddit-style comments that add nothing to the conversation rather than "the fanbois" taking up for Apple. You aren't new here so I assume you either (a) knew that, or (b) are assigning the blame for the wrong reasons. Had you taken as much time (or put in as much thought) with your original comment as you did with this follow-up, I suspect you would've had upvotes.
- ghshephard 13y agoAnybody with an iPhone 5S see the problem? My iPhone 5 is dead level on when I put it on a known-level surface in portrait, landscape format, or flush flat - well, to within 1 degree (I don't get 1/2 degrees on the iPhone 5) You are required to calibrate it by spinning the "ball" around prior to using it though.
- arrrg 13y ago5S, 3° off on a flat surface.
- ghshephard 13y agoInteresting - Did you run the calibration process? (Spin the little virtual ball in the "roulette" wheel)
- arrrg 13y agoYou pretty much have to, every time you launch the built-in compass app. I feel this process is mostly for the compass, not the level. The 3° are consistent, across multiple tries for several days. I think there will have to be a software fix. Seems like their calibration process in the factory was off or something. No big deal but annoying.
- panacea 13y agoMaybe you're 'holding it properly' or aren't trying to get clicks for heralding 'sensorgate'... or maybe this is another fucking stupid storm in a teacup. A quick rinse and a new teabag usually sorts it out.
- Gigablah 13y agoMy 5S is consistently 2° off compared to my colleague's 4S.
- Cthulhu_ 13y agoOfftopic, but I like how the article calls the 5C "relatively inexpensive"; it's still a high-end (priced) device that looks intentionally low-price / less refined.
- brunnsbe 13y agoGizmodo has a more detailed article with some tests from last week: http://gizmodo.com/the-iphone-5s-motion-sensors-are-totally-screwed-up-1440286727 http://gizmodo.com/the-iphone-5s-motion-sensors-are-totally-...
- nwh 13y agoHave the sensors ever been good? I've always found the compass to either constantly lose calibration, or when it finds it, it's a good 90° off where it should be. Since they introduced the hardware in the iPhone 4, essentially.
- craigc 13y agoI'm not entirely sure why this is a big deal right now. I had an iPhone 1 and when the App Store opened up I downloaded Cube Runner. The accelerometer calibration was off by A LOT. Just keeping my phone flat on the table would cause the ship to shoot off far to the left. I actually had to replace my iPhone at the Genius Bar (I think more than once) in order to get one that worked better. Since that was over 5 years ago it is very unlikely that Apple will now decide to offer software calibration in the OS. As for this comment from the article > Unfixable sensor problems, however, would put a dent in Apple’s reputation as the company that sweats the small stuff to get every last detail right. I am pretty sure iOS 7 already did that.
- roflcopta 13y agoI don't have an iPhone5c/5s to attempt this myself but what I was informed is that you have to: > place the unit into "Do Not Disturb" mode be sure to turn off any type of call from anyone, and always silence. > place the unit on charge > let the unit sit flat on the backside for 90 min (home button facing up) > check status. Someone want to try this?
