As iOS 7 continues to go through beta testing, more and more is being revealed about the engine that will drive home the next generation of iPhones. While there has been quite a bit of talk on what new innovations to expect with iOS 7, criticism of the new operating system has been suspiciously absent.

"Little has been revealed about some of the long-standing frustrations of iOS, either by Apple or by writers who've decided to violate their secrecy agreements with Apple and publish details on the beta iOS 7 now in wide testing by those with Apple developer accounts. With the new iPhone apparently scheduled for a September 10 reveal and a ship date of two to four weeks after that, iOS 7's formal release isn't that far away," writes Galen Gruman for infoworld.com.

Granted, there seem to be a lot of good things to say about iOS 7, if for no other reason than it will offer a more efficient, complex experience to an already stellar phone. Due to lines of code found inside the latest iOS 7 beta test, there has also been talk of thumbprint scanning software embedded into the next iPhone.

As with many things in life, however, the devil is often found in the details. In the case of iOS 7, that devil appears to be an overactive color palette that looks more like a child's neon crayon box and less like the mature, sophisticated aesthetic we are used to seeing from Apple.

"Yes, the software may have had a lick of paint too much to the point where it looks almost burlesque in nature, as though Apple's suffered a mobile mid-life crisis that has it slathering animations and gyroscopically activated wallpapers," observes Zack Whittaker of ZDNet.com.

Scathing comments on the color pallette of iOS 7 aside, there are also more serious points of contention. Chief among those concerns is the "Frequent Locations" functionality, which tracks the user's movements and keeps a full log of locations they have visited. In the wake of the NSA scandal, many people find such technology unsettling, though at the present time it is easy to opt out of Frequent Locations.

Then of course there are the more mundane, but still vital, day-to-day functions of iOS 7. Whittaker also noted that the placement of Spotlight was clunky, and certainly some people will not appreciate having to read out what the weather will be rather than just have a number and symbol instantly inform them. Gruman also pointed out this pitfall involving what should be a phone's chief concern: communication.

"iOS can't create groups of contacts, and it can't send email messages to a group synced from your Mac or PC. Both are nutty omissions, given how fundamental groups are to email and other communications. Worse, if you select a group as an addressee in Mail, you get a list of the members, of whom you can pick one and only one to add to the To or Cc field of your message," he writes.

As it is still in beta, it is anyone's guess what the final version of iOS 7 will include. With the rumored Sept. 10 reveal date looming, however, there's a good chance that this version will be more or less what to expect in the final product. What do you think, is the progress made by iOS 7 enough to overcome its shortcomings? Comment below and let us know.
