Samsung Galaxy S 5 Review

The Galaxy S5 is another phone to join the list of phones that ship with a fingerprint scanner for unlocking the device. While the Motorola Atrix 4G was the first to have a fingerprint scanner, it was mostly forgotten as a feature until Apple reintroduced it to the market in the form of TouchID. HTC also released the One max with a fingerprint scanner, which was generally viewed with mixed reactions due to the swipe sensor. Overall, it seems that while no one has a perfect implementation, Apple has the best implementation on the market today.
I do think it's important to give Samsung some credit, as the Synaptics-provided capacitive fingerprint scanner does work. Although not perfect, the GS5 is definitely better with its fingerprint scanner than had it shipped without it.
Samsung integrated Paypal and Samsung Account verification into the fingerprint scanner software as seen below, which is neat and shows the direction that fingerprint scanners could take in terms of identification and verification.
The fingerprint scanner is a high-DPI capacitive one based upon the Chipworks teardown, and in effect, is identical to the fingerprint scanner in the One max. The big difference is that it's integrated into the home button on the front of the phone as seen above, although based upon my experiences the home button is the only area with high precision capacitive sensing. The sensor detects features of the finger by measuring the effect that the dermis of the skin has on the electrostatic field that is generated by the touchscreen, and at sufficiently high resolution, the sensor can interpret the effect accurately enough that a map of the finger can be generated.
What is different from the One max is that it is much more difficult to use. The enrollment process is simple enough, and is accomplished by swiping eight times over the sensor as seen above (just like with TouchID, you can enroll multiple fingers in place of one by switching the digits you swipe with during the 8 swipe training process). After that, the fingerprint scanner can be used as a unlock method, along with the Paypal and Samsung Account login as previously stated. Where things get difficult is actually unlocking the phone. The sensor is simply too low to reasonably use with one hand, especially because the fingerprint scanner requires straight swipes with very little diagonal deviation. The scanner is also quite sensitive to swiping either too slow/fast or swiping at an inconsistent rate, and will often fail if the user is not consistent in swiping from enrollment to unlock. Enrolling the finger at multiple angles does help a bit with the issue, but it doesn't fundamentally change the experience.
It's pretty easy to adjust to the GS5's fingerprint sensor if you give up on the hope of a one hand unlock. If you're ok with swiping with another hand, the sensor works pretty well and is a great alternative to a long password.

It's a shame that Nokia picture samples aren't included in comparison. Either Lumia 1020, 1520, or Icon (930). Heck, even an older 920/925 would be adequate.StevoLincolnite - Tuesday, April 8, 2014 - link
Yeah I wouldn't mind a Lumia being included in the comparisons, then we can see how every platform stacks up in these reviews.inighthawki - Tuesday, April 8, 2014 - link
On top of that it would be nice to see the results of at least some windows phones on the graphs. I can understand that a lot of windows phones have lower end hardware because they aren't very resource intensive, and thus probably don't always top the benchmarks, but it would be nice to know how they compare. Even if it's just a single entry at the bottom as an "FYI"mtoma - Tuesday, April 8, 2014 - link
I believe the review lacks the comparison with Windows 8 phones, because this site has no reviews with ANY Windows 8 phone. It just avoids them. At least Brian Klug did that. So, if he's not around, the better the things will be. Let's see if anything changes here. In the mean time, as far as smarthpones goes, I read mainly other sites.coburn_c - Tuesday, April 8, 2014 - link
Doesn't the Sony use the same camera hardware?melgross - Tuesday, April 8, 2014 - link
Did you read the whole review? If you did, you would have read that this is Samsung's own sensor this year.kyuu - Tuesday, April 8, 2014 - link
Yeah, I'm curious if Anandtech is still going to ignore Windows Phone entirely (as far as full-length reviews go) as it has since the WP8 was initially released. I guess time will tell.wrkingclass_hero - Tuesday, April 8, 2014 - link
Did Brian Klug leave? I haven't seen anything written by him in a while, and his twitter hasn't been updated.BMNify - Tuesday, April 8, 2014 - link
yeah, good to see that Brian Klug is no longer writing for Anandtech, he personally hated Windows phones and used to mock them publically. Also, there was no review for Nokia phones eventhough Nokia sent all the flagship models last year like 920,925, 1020 to Brian Klug.And from what i can make out this fiasco has led to Nokia no longer inviting Anandtech to their events and no samples too, hopefully Anand or the new writers can restore the relationship.

Yea I agree they seem to ignore that platform completely. They reviewed the HTC 8X but that is the last I saw out of AT here.
