A report by Crittercism indicates that Apple's latest and greatest product, the iPhone 5s, is twice as likely to crash compared to the predeceasing iPhone 5c and iPhone 5. The report indicates that the iPhone 5s has a 2% app crash rate, whilst the iPhone 5c and iPhone 5 apps crash just 1% of the time.​
The reason for apps crashing twice as much is currently unknown, however, it's thought that the new A7 chip may be causing the issue. At the time of development, developers only had access to the iOS 7 beta and not to the 64-bit A7 chip and M7 coprocessor. Therefore, only a limited amount of testing could take place. "Anytime there is new hardware or software release, we see issues. Inevitably, over time, those issues get resolved," said Crittercism CEO Andrew Levy.

Levy explained that it's not uncommon to see higher crash rates when new devices or operating systems first come out. Developers did a great job at providing a seamless transition when converting to the 64-bit processor, which was achieved by writing new drivers and other code. The CEO then went on to talk about Apple's good response to bugs and issues found on their devices: "The good news is that Apple is certainly aware of issues. They’ve pushed out two iOS updates for iOS 7..." said Levy. "Apple is doing a really good job of addressing these issues as they come up.”

Another issue that some users seem to be experiencing is the 'blue screen of death.' It appears the common Windows PC problem is expanding to the iPhone 5s. Several owners have reported that after using such apps as the iWork suite, the phone would enter a 'mean shade of blue' followed swiftly by a restart. Another user reported the same issue when using the ESPN app. The problem was spotted on the 21st of September, one day after the smartphones release. Apple has yet to comment on the issue.

Despite two new updates since the iOS 7 release, it appears nothing has been done (that we know of) to resolve these issues. Currently, Apple is yet to comment on either of the bugs, acknowledging their existence. However, I'd be very surprised if such issues aren't fixed by the end of this month. To those of you who own an iPhone 5s, have you experienced the blue screen of death, or even an increase in app crashes? Let us know in comments below.
