Why a rear finger scanner on the Galaxy S8? Samsung ran out of time with the 'in-display' tech by Synaptics

Why a rear finger scanner on the Galaxy S8? Samsung ran out of time with the 'in-display' tech by Synaptics
If you, like us, have been wondering why is Samsung going with a rear finger scanner for the S8 that is in one unorthodox place right next to the camera on the back, a new report out of Korea sheds some light on the matter. It turns out that Samsung may have simply run out of time to implement Synaptics' new in-display finger sensing technology. This one is still in its nascence, and there is no manufacturer that has fully implemented it yet. Moreover, the Galaxy S8 is likely to come with a unique curved display with a new resolution in order to fit in the trendy 2:1 aspect ratio, like the LG G6 does, so Samsung might have focused on getting the more important screen characteristics right first. 

According to one insider source: "Samsung poured resources into Synaptics’ fledgling technology last year but the results were frustrating. With the production imminent, the company had to decide to relocate the fingerprint scanning home button to the back of the device at the last minute." There you have it. Synaptics is indeed talking about in-screen finger sensing at a preset area as the current step in its developments of the technology, which would imply it is still not completely out of the testing phase, while the next and final step would be placing a finger scanning area anywhere on the screen that the manufacture chooses. 

That's still some time off, but, given that Apple will have a bit more time before it announces an eventual OLED iPhone 8, we are curious if it will have the in-display sensing tech that the Galaxy S8 eschewed. That could steal a bit off the Galaxy thunder, but Apple has never been one to jump on nascent technologies ahead of the pack before they have been proven in the market, so we'll see how it all pans out.

Considering they make alot of components for Pixel, Iphones, Huawei im sure it be ok. Yes samsung even make batteries for iphones. https://forums.macrumors.com/threads/oops-samsung-sdi-is-in-apples-supplier-list.1994723/ Yet people still wanna bring up the past and not the future. Maybe all these other companies should find someone else to make the components for them?? Guess even after them rushing things and exploding phones companies like Apple, Google, Huawei and Snapdragon need SAMSUNG!!

Its the pre explosion list. Things might have change especially when choosing the battery supplier.

i will never understand how anyone figures the N7 was rushed. all Notes were released withen the same 3 months...

What contributed to the note 7 problem was the sharp curve on the edge of the phone and tightness of the chassis. This squeezed the anodes and cathodes together inside the battery often causing a short, which then results in a non-passive thermal event.

Maybe saving that and 4k screen for the note 8 to make up for the note 7

So basically it was just bad timing, and Samsung is involved in the development of the tech. Yet I can already see the S9 reviews mentioning how "Samsung copied Apple" next year.

LOL..Samsung copied Apple next year..the accuracy.It's ridiculous isnt it. Saw an article saying that the curved 'all screen' design of the S8 is copying the anniversary iPhone

And guess some people will skip the S8 for Note 8 then.

And guess those who wanted the Not8 weren't even considering getting the S8 in the first place.

Placing the fingerprint scanner on the back was a very big mistake from Samsung. A better move would have been to place it in the small bottom bezel, without a clickable button maybe. Sony placed it in the power button, so a narrow fingerprint scanner is possible. Iris scanner could save the day, but the front-placed fingerprint scanner remains the best option by far.

"Placing the fingerprint scanner on the back was a very big mistake from Samsung." Just like how people slammed LG for putting the volumes button at the back of the G2...yet it later became the G2's selling point, with reviewers and comments on YouTube praising it. SMH

Actually LG reverted to putting the volume buttons on the side since more than one year ago, due to criticism (imagine adjusting the speakerphone volume in a variety of situations like when on the table or on a car cradle). If this was the selling point, they would have kept it. Same with the fingerprint sensor. When it's on the back, you can't unlock your phone while in a table or on a car cradle. SMHx2

"Actually LG reverted to putting the volume buttons on the side since more than one year ago, due to criticism" What proves that LG ditched the volume buttons at the back due to criticism? LG simply could have felt it was time to change design, as the volume buttons at the back stopped being a selling point in 2015, probably because LG's consumers wanted something different, or because it wasn't practical enough on the G5's metal build... or perhaps, because the back of the G5 was already occupied by dual-cameras and a fingerprint scanner. But it was a selling point back in 2013 with the highly acclaimed LG G2, as well as the LG G3. So, my point still stands. SMHx3

How many shakes does one SMH count? A SMHx3 would be crazy.

Ummm but since they have the iris scanner they get rid of the redundancy of having finger print scanner that was way more convenient than the iris. now if folks don't want to pick the phone of the desk they tap the screen and scan the eyes.

First of all, this is not one of those things that need to be proven in the market. Either it works or it don't. Either it's ready for production or it isnt. Also, this has been rumored for the iPhone for a couple of years now. With the rumor that the phone will possibly be delayed until November, there is plenty of time. One thing you won't see is Touch ID on the back!

So why not keep the home button on the front and minimize the bottom bezel? This back location is pretty weird, not even centered like most phones with a rear fingerprint scanner.

Just don't rush the Note out. Too late for the S8 but still have time to do right with the Note 8.
