The iOS 7.1.1 has been received with mixed views, though leaning towards the more positive spectrum as more fixes and improvements roll out with the update.

One of these includes the improved Touch ID so you can easily get into your iPhone device even faster. This is apparently the fix for some iPhone users who have been facing problems with the Touch ID before the iOS 7.1.1 was released.

According to MacObserver, what you have to do is to completely reconfigure the Touch ID by deleting your fingerprint profiles and re-establishing it with a new one, as the iOS 7.1.1 actually improves and expands the scanning during the fingerprint enrollment process, most of which have minimized possible errors in the overall fingerprint scanning.

Vulnerabilities for email attachments

While the iOS 7.1.1 is supposed to fix a couple of bugs and problems with the previous update, it seems to be bringing along a few risks of its own, starting with an email vulnerability found way back.

Softpedia reports that the new bug was found by security researcher Andreas Kurtz, which basically puts your email attachments at risk. Apparently, the vulnerability was confirmed using an iPhone 4 that has the iOS 7.1.1 update and setting an IMAP email account.

According to the report, the sent email was checked to see its security integrity and was found that the attachment with the email can actually be accessed without any encryption or restrictions. For now, Apple is already aware of the issue but apparently did not make use of the iOS 7.1.1 update to fix it.

Whether or not Apple is planning to address this issue in a later update or not at all remains to be seen, as Apple is not saying anything about how it plans to deal with the latest security vulnerability.

Beware of crashes-at least with the iPhone 4 and 4S

If you're a user of either the iPhone 4 or iPhone 4S, you may have to add another vulnerability with the onset of the iOS 7.1.1. Macrage has found a number of complaints from users who have been reporting about their iDevices crashing or being unable to send or receive messages and make calls.

The trouble here is that, despite Apple's quick fix of restoring the iPhone, the users are claiming that their iPhones won't even start working or reading the SIM card. What's even sadder is that, given that these are two older models of the iPhone, it won't be eligible for a trade-in program, and those who are no longer under warranty would have to buy a new iPhone.

Among the complaints and comments of users are claims of having tried everything to restore their files to no avail, or some losing data in the process of restoring the phone. One way to restore would be to find the Connect iTunes screen as it may allow you to restore your iPhone via iTunes, though this may require a few tries with no guarantee of working.

Better battery life: Go or no?

The verdict for the battery life after installing the iOS 7.1.1 update is still split in half, as some users are claiming battery life improvements while others are stating the opposite, which is possible battery drain.

BGR reports that it does improve battery life, improving on the iOS 7.1 update, which effectively halves the iPhone battery in a matter of six hours. Proof of the improvement, according to the report, is that one user still had 76% of the charge after the six hour testing time when he upgraded to the iOS 7.1.1.

However, in some forums like on Macrumors, there are users who are reporting lousier battery life after the upgrade. "I updated a few days ago and I noticed during the overnight hours my phone is draining for some reason while it's just sitting there doing nothing," said one forums user.

Other users are claiming that the issue may have begun as early as installing the iOS 7 update, with one user saying that most of those that he knows who are having the issue also own an iPhone 5.
