The biggest complaints about iOS 7 so far

For some users, iOS 7 isn't quite heaven.

iOS 7 is the Apple's largest update to its mobile operating system since iOS was introduced in 2007, a  rewrite in design and rearrangement in functionality. And when these big changes began to roll out to iPhones and iPads worldwide earlier this month, complaints and user frustration, fair or unfair, weren’t far behind. Let's take a look at the biggest complaints about Apple's new iOS so far:

SECURITY GLITCHES

One problematic, but now patched, iOS 7 security flaw allowed for the circumvention of a device's lockscreen, as reported CNET. From a locked phone or iPad, swiping up to access the alarm clock app and following a couple extra steps brought up the iOS 7 multitasking screen where you could access the camera app or photo gallery. This opened a clear path to Twitter, email and other accounts. Apple replied quickly to this vulnerability by releasing an iOS 7.0.2 update late last week, fixing the bug.

UNWANTED LOGOUTS

One problem that’s vexed iOS 7 users and developers alike is a glitch that logs users out of some apps, according to The Verge, prompting a sign-in screen each time an app with a unique account is accessed. Popular iOS email app Mailbox was “in crisis mode” shortly after the release of iOS 7, attempting to fix the software conflict as users grew agitated. According to Mailbox, the only solution, though a temporary one, is to disable iOS 7’s new background refresh feature, though this removes the app’s ability to receive updated information while in the background. This issue remains unaddressed.

BATTERY LIFE

Diminished battery life has been one of the top topics of discussion from those that have updated their iDevices. As reported by PC Magazine, the difference in power consumption is often hard to quantify, seeing as each user uses his or her phone differently and with unique configurations, though it is worth mentioning that Apple did address a similar battery drain claim with a patch to its iOS 5 software. In the meantime, some sites have compiled best practices lists to aid users in conserving battery life, suggesting things like turning off background app updates and disabling AirDrop (Apple’s new wireless file sharing service). For example, the Huffington Post's Alexis Kleinman put together this primer on how to save battery life with iOS 7.

MOTION SICKNESS

Another odd claim about iOS 7 that’s receiving plenty of press: It makes users sick. As a report from NBC News asserts, iOS 7’s new 3D desktop might be giving iPhoners vertigo-like symptoms.

"We haven't done any experiments with this phone, but this is what I think is happening — it's definitely linked to the motion of the screen,” psychologist Frederick Bonato, of Montclair State University in New Jersey, told NBC. Tilting an iOS 7 device back and forth moves the app icons accordingly to create an illusion of depth. Apple calls it parallax.

"Seeing a three-dimensional space, on a phone you know is flat, can trigger queasy feelings,” said Bonato.

Simply disabling your device’s gyroscope (also a battery saving trick) will put an end to iOS 7’s 3D effect, and hopefully ease your stomach, too.

PROBLEMS WITH iMESSAGE

Many iOS 7 adopters have posted complaints to social media about their difficulties sending messages with the newest version of iMessage, Apple's all-encompassing messaging platform for texting and desktop chatting. According to The Wall Street Journal, Apple has acknowledged the bug and is looking to the resolve the issue as soon as it can. Tech site BGR has reported that we should expect this fix to come next week by way of Apple's second patch update to iOS 7.

DESIGN FLAWS

Then there are the visual imperfections. One place to get a glimpse of all the places where iOS 7 is a bit off in design and compatibility with third-party apps is sloppyui.tumblr.com. Though this user-submitted Tumblr is described as being “all about intellectual honesty, not trolling,” it’s full of, well, sloppy design inconsistencies and errors, and seems a little troll-y.

Now, these “issues” may be a bit picky, seeing as most software is slowly revised and refined after an initial public release. In fact, to be completely fair, Google’s Android, iOS’s most formidable competition, has never pulled off a launch the size of iOS 7. Most of Google’s releases are adopted slowly, and forked into versions tinkered with by Samsung, HTC or Motorola.

Other complaints about the new version of iOS are far more subjective: “New calendar on iOS 7 is so annoying,” for example, or “Finally got iOS 7 and its ugly and i wish i wouldn't have updated it,” as put by two Twitter users. Many of the new features and designs in iOS 7 are a large leap from iOS 6, and sometimes change is hard and simply takes some getting used to. Of course, for users who are really upset with the update, there is a way to make everything better:
