Many stories about faulty sensors on the 5S. Mine has the issue and crappy call quality, which I have now seen on two phones. I will be returning the phone and asking for my money back. Very disappointing.

Many stories and yet Apple Store geniuses, who I trust, are not reporting returns off either issue. I questioned how Real Racing 3 was working. I reset the iPhone and things track normally, equal to my iPod Touch.
There is an option for compass settings if that's an issue. You weren't specific about either so hard to reply.
As far as call quality, I have ALWAYS had an issue with the other party hearing me if I was holding the phone to my left ear with my right hand.
Money back or exchange? So little faith in Apple and you're invested in it?

So little faith in Apple and you're invested in it? I already exchanged the product once, and the call quality is still a joke. My call quality problem is left-ear, left-hand. Right-ear, right-hand is better but still really poor. The speakerphone is outstanding which makes this even more ridiculous. Me being a product owner and an investor are two separate issues. When I spend over $900 on a phone, I expect it to work. On a flat surface, the sensor is off by 4 degrees when on its edge, and 5 degrees when laid flat. This is the new spirt-level feature in the compass app.

My call quality is much better on my 5s than it was my 4s. Lstream, could it be a carrier issue? I'm on GSM ( AT&T)

Just a week or so more, then I get to pace the 5S for myself...
Luckily my trusty 5 is as capable as ever, if mildly slowed by iOS 7 and the battery maybe 75% of what it once was.

The feedback from friends who've purchased the 5s love it. It's without a doubt, the best iPhone I've purchased. If there's a firmware/software update to address some minor issues following new hardware and a leap with iOS7, so what? For all the things Apple does right, doesn't it deserve a pinch of goodwill here?

It seems like people bring up max pain and weekly pinning a lot, so I thought I'd through my two cents in. One thing that I briefly brought up a few days ago, but doesn't get nearly enough attention is how the vast majority of large option players use delta neutral strategies. This means that while they take on huge options positions, sometimes with large positive or negative gamma and theta, they're constantly hedging their positions to bring the overall delta as close to 0 at all times. These option traders get their edge from any number of places, but it's not from choosing a stock's direction. As far as stock picking, their primary concern is NOT losing money, hence their preference for going home every night with flat deltas. Why is this important? Because it's the primary reason pinning exists, but ironically it's for the opposite reason that most believe. I feel like a lot of people look at end of week options pinning and say, oh it's all the option writers trying to pin the stock to make the contracts they're short worthless. This absolutely isn't true. If an option player is short a bunch of calls at an at-the-money strike, every cent that stock moves up and away from that strike price, the gamma of their short options is causing their deltas to go more and more against them. For them to then try and short the stock to bring it back to the strike price, would just be making their deltas even MORE against them. This is the opposite of hedging. But more importantly, this is a classic sucker's trade. It's a trade with a high probability of a small winner, and a small probability of a large loser. Trading firms HATE these trades, because it's so hard to judge the profitability of them because they're always at risk of huge blow ups when things go wrong. It's extremely hard to accurately estimate either the likelihood or the magnitude of a blowup, let alone both which you need to judge a strategy's profitability. So what does cause the pinning? Anecdotally, it obviously exists, and it's actually the long holders of the at-the-money contracts that are causing it. An option's gamma is greatest when it's at the money, so when someone is holding a bunch of contracts at the money and the stock moves higher, their delta is going to move in their favor very quickly, because their gamma is abnormally large. This means they're going to have to hedge more aggressively than normal, which means when the stock goes up, they sell, and when the stock drops, they buy. This is what causes the pinning. Yet another thing that goes against the idea of shorts pinning the stock at a strike price is the idea of "pin risk". As I've mentioned before, these large option players want to stay delta neutral as much as possible. Imagine a scenario where an options player is short 1,000 AAPL 500 calls and the stock closes at 499.98 on expiration. Everyone would think, that's great, right? All these contracts they are short basically expired worthless. Now let's say in after hours the stock trades up a few cents and prints around between 500.10 and 500.25. Here's the problem... this options player, who needs to be somewhat delta neutral or face the wrath of their risk manager, has no idea what their AAPL delta will be come Monday morning. The stock closed at 499.98, so brokerages won't automatically exercise any of those 1,000 calls. But the stock was up slightly in after hours, so plenty of those 1,000 calls may get exercised. But they won't get notice until Saturday morning, way after afterhours trading has closed when they could hedge. They may get assigned on 200 or they may get assigned on 800. The difference between those two scenarios is 60,000 delta. If they knew, they could hedge, but they don't know and that's a disaster. That's why, ironically, for an option trader going into expiration the WORST thing to happen is to be short a ton of contracts pinned at the close. So what does all this mean and how do you interpret it? It's all about the gamma. If it's option expiration Friday and AAPL is trading at 508 and there are 80,000 500 strike calls, you might be tempted to think, oh those option market makers are going to try and push the stock down because 8 points lower and all those call expire worthless. But in reality, if it's Friday those calls have so little gamma left in them that the option players have basically written them off as 100 delta contracts and they're already completely hedged 1 to 1 with stock. Now, when the stock is trading around a strike price approaching expiration, there will be that pull towards the strike because of all the hedging from the elevated gamma, but the further it gets from the strike, the less of a pull there will be. Overall, the effect gets greater as the minutes tick towards the close and the end result is it's much more likely to bring a stock from 500.50 at 3:50 pm to 500.00 at the close than it is to bring a stock from 496 at the start of the day to 500 at the close. Overall, I think most on this board are placing too much emphasis on it because they see the closing pins and that is exaggerating the actual effect of what's going on. Good post. In the olden days we had an options thread where these strategies were discussed. The subject (delta neutral volatility trading) is extremely complex and the mysteries are sometimes deep. In addition to delta neutral trading, I have experimented with gamma neutral trading, especially around earnings announcements. Won more than lost, but I mostly attribute that to luck, because I often was surprised by outcomes. I have no opinion on the effect of weeklies, but I do dislike that they exist. I believe that pinning is a natural phenomenon; a good volatility trading book will explain it. Natenberg is one I use, but there are more recent volumes that would be more up to date.

Well, we DID get new guidance. But yeah, I'm convinced Apple is determined to boost margins during FY 2014. We should get a taste of that with guidance in October. The iPhone 5 build issues didn't help. The 5c (and the space gray and gold 5s) should enable a return to 39-40% GM, at least. I really do think Tim and Co. were surprised by iPhone 5's semi-tepid growth. On the bright side, they may be surprised by how popular the 5S seems to be. S generation effect, I tell you. The S generations seem to coincide with expanded launches on more carriers, makes sense that we see a larger bump in sales growth with the S models.

My company spent millions creating an iOS-only Enterprise app. We are swinging decisions away from Android and Windows with it. Thousands of devices. So lay off with the snide remarks and insinuations. Grow up.

I found this statement particularly awkward. I mean, come on, how can a device that is doing no better than 2nd at two of the four largest US carriers slow share losses. ... They are referring to the just released Galaxy Note 3, not the galaxy S4. Regardless, the Note 3 is a niche product, and unlikely to have much impact (if any) on apples Q1 sales.

Surface2 ads:Why should anyone believe them. (Setting "us" here aside, because we know better). What about GP, the general public?
***
GP:
Microsoft, you told us that Surface 1 was great. The dancing, the clicking, the keyboard, the over-the-top advertising, we could have it all with the first Surface. We could... (Windows!) be free, have the best (Windows!) of both worlds, Windows!!!!! And the reviewers jumped out of their pants to praise it.
But then, why the price cuts, I hear nobody bought it. The ads finally comparing (Surface 1) to the iPad, I'm confused, how does a thing that nobody bought get away with mocking the iPad?
Now you roll out Surface 2 and tell me it's just great. Why should I believe you? If I'd bought Surface 1 it would have been $hundreds on what is now junk.
WHY should I believe you?
***
Contrast this to Apple, which doesn't release junk. First versions of iPod, iPhone, iPad: beautiful earthshattering first iterations, NOT JUNK, still usable years later. (See: original iPod, original iPhone, original iPad, which I still hold and which all STILL WORK, years-to-many-years-or-decades later).
Vs. Surface 1, Galaxy Gear ($throw away $299, junk), we could go on to other failed hardware efforts that we all know about.
I have a hard time believing people are going to be fooled into buying Surface 2 when they know that Surface 1 was a waste. It never should have been brought to market.

I just returned from a Microsoft store to check it out. Not much of a crowd for a new product, but I played with it and I'm sorry, the build quality ain't there. It's a flawed product, trying to be both a tablet and ultra book doesn't work. I've seen better stuff from DELL, however, if one really needs to combine the two. RT is DOA. If there's any hope for Microsoft to pierce the tablet market, it's more likely to come from DELL, which has a big pricing advantage. To my eyes, without the benefit of a hands-on view, the DELL looks like a better built product. Anyone in enterprise isn't going to like doing Excel or Word on a touchscreen tablet. And balancing a touchpad on one's legs won't be acceptable either.

Especially since it is speaker dependent. Identical problem on two devices.
