Tech giant Apple recently unveiled its flagship smartphones this year - the iPhone 5S and iPhone 5C.

Apple revealed the iPhone 5S that took the $199 slot and features some of the iPhone 5 specs along with other features such as the new 64-bit A7 processing chip with M7 motion-sensoring chip as well as the fingerprint sensor on the home button.

The iPhone 5S costs $199 for 16GB, $299 for 32GB and $399 for 64GB with the usual two-year contract.

However, some problems were found on the new iPhone 5S. Below are the five problems found on the latest iPhone 5S.

Camera is not that amazing - iPhone 5S still includes the same iPhone 5's camera as Apple did not increase the megapixels on the new full-fledged iPhone. Although Apple said that it packs better camera software, it is nothing compared to the camera of other smartphones like Samsung Galaxy S4 Zoom and Nokia Lumia 1020.

No NFC - To the dismay of many fans, Apple still left out Near Field Communication in the features of the new iPhones. Most Android-based smartphones offer this feature in transferring files as well as making wireless payment, although the latter is not much explored.

64-bit Processor not optimized - iPhone 5S is the first smartphone to use the 64-bit processor and although the new iOS 7 supports optimisation of the new CPU, it is a must that other developers get hold of the technology. Thus, we may see the complete benefits of the new processor a little later when developers already adapted on the new CPU.

Small screen display - iPhone 5S packs the same 4-inch screen display that some consumers find too small compared to other smartphones in the market. At least 5-inch display seemed to be the latest trend on screen size today, especially after Samsung unveiled the Galaxy Note 3 with a massive screen display.

Fingerprint Scanner is faulty - One of the most intriguing features of the new iPhone 5S is the fingerprint sensor. However, the new feature has some pitfalls. For example, it does not work when you are wearing gloves, which is a simple problem that most medical practitioners may face in checking their phones.
