LG G4 to ship with a fingerprint scanner, guess where it might land
Not to be left out of the biometrics race, LG is apparently planning to equip the upcoming G4 flagship with a fingerprint scanner in its turn, cite industry sources. We've been hearing since the G3 that LG is mulling a finger sensor, but evidently the technology has reached enough critical mass now that Apple and Samsung are firmly onboard for LG to warrant the inclusion.

LG Electronics has recently decided to deploy a fingerprint sensor on its next flagship smartphone and the scanner will be placed at the back of the device,” tips the source, as the company "has been left behind in the race for fintech (portmanteau of finance and technology) as it has continued to postpone the adoption of fingerprint technology.” 

LG had the extra Knock Code layer of security implemented in the G3, but in the world of Apple and Samsung Pay this might not be enough a year from now. Plus, embedding the fingerprint scanner in the home key at the back will allow for the company to try and achieve the same excellent screen-to-phone ratio it managed with the G3.

on the back where the on/off and volume controls go. I think it would be great right where the on/off button currently is located. In fact make the on/off the scanner.

IMO that would be very bad experience because knock to wake up wont work. I've used LG G3 and its very convenient feature because power button at the back side.

Yes, that is indeed the best location for the scanner, having had the Originall Motorola Atrix with its fingerprint scanner at the top back is the best since you can turn it on / unlock at the same time you are taking it out of your pocket... Neither Apple nor Samsung comes remotely close to having the positioning right when it comes to the scanner.... Of course the older one on the Moto needed sliding, but for me it worked incredibly good. If LG does this and put it at the back on its ON/OFF button then it will most definitely be the best position and the most practical out of the current generation... EVEN if it needs sliding the finger...

What happened to Pantech? They've got impressive device before but doesn't expand beyond Korea, Japan, and US.

Where Samsung leads, LG follows, but they do it with taste and style and put their own stamp on it.

Bearing in mind the G3, it definitely has taste and style PLUS its own identity compared to Samsung...looking forward to see the new G4

LG should wait to adopt the fingerprint sensor embedded on screen rather than putting it on the back because it isn't comfortable and doesn't look nice at all

At first, I thought the rear buttons were atrocious. But with the G3, LG really improved on them and they look stunning. As does the entire device itself.

I currently own G3, and I've to say it's a great phone. Imagine if they put all buttons and add a fingerprint sensor together on the back, it won't look so attractive in my opinion.

the fingerprint sensor can be embedded into the power button so it wont look cluttered

im excited for this phone. I got the s4 2 years ago because the g2 wasn't out and boy do i wish i waited. Maybe the s4 is better than the g2 but just to have the different style that the g2 and so on has would be fun. hoping the g4 is also simliar

Same. I bought an S4 2 months ago. The next day I saw a sale on ebay of LG G2s for $200. I been kicking myself ever since

You should be kicking yourself for buying an S4 period.

I bought my first 'big name' phablet after avoiding the masses for so long that flock to Apple, Samsung and LG G3... I didn't believe in paying so $$$$ when a Chinese made phone 1/4th of the price can do 80% to 90% of its tricks. LG G3 had a great camera....most of the time. I can see why people pay premium for top of the line devices... But... LG G3's camera was slow in the dark. It was always hunting for a shot. My Chinese phone can snap pictures much faster and looks better most of the time. Of course LG G3 kills it in daylight and image quality. But it is not as clear cut as most make it out to be. Also, the down fall for me (I gave my G3 to a friend) was the battery life... It's something LG has tried to cover up literally since day one. No wonder they quickly offer you a free extra battery life. The QHD drains the phone very fast. Even when you put the phone on dim (which it does anyways most of the time). I like to surf a lot. My guess is with screen turn 1/2 brightness, it will last 3-4 hours max. A few times when I turn the brightness on high and running few applications, downloading, it becomes 'too hot' and adjust its brightness down. Overall, had a mix feeling about LG 3. IT cost $100-$200 less than competing names, but if I had to do it again, I would've bought one of the other 2. Mostly because of the battery life is awful. I know you can just 'change' the battery. But it needs to have decent battery to begin with so I don't have to constantly buying new batteries to change it. I may go through 2-3 batteries a day because I'm such a heavy internet user. So sometimes big names are 'big' for a reason. The other two seem to have much better battery life. I don't know what LG was thinking with the G3. It's a lovely phone.. but they missed a golden opportunity by deciding to go with QHD when the technology was so nascent. When they got such low score on battery life, they should've nixed it in favor of longer battery life with 1080HD screen. Oh yea, the power button on back gets old fast. It's easy to mislick it. Hard to adjust the volume button. I would NOT buy the G4 if they fixed everything else I've mentioned AND kept the same on/off button orientation WITH the finger scanner in the back. It is very hard to do things in the back. Its NOT in the back for a reason.... SOmetimes I swear LG does things just to be different, not practical.... At least someone is enjoying a free G3 phone... free is always good. As for me, I would never fall for those gimmicks again...

The problem is you're licking the back buttons instead of clicking them. Your tongue must be brawlic by now.

I rather have a brawlic tongue than a LG 3 shaped bun-hole. All that brown-nosing for naught..

I also want to add.. my G3 ran a bit sluggish despite having 2.5 ghz chip. There is always enough pause to make it less smooth than it should be. I even got rid of all the animation and unnecessary 'delay'. It doesn't feel like a 2.5 ghz chip. After the Android L update, it was a bit better, especially the camera. But still not impressed with the battery life at all, not much improvement with Lollipop. It is still a good phone, but not one of the best you can buy for top end.

I have the G3 and the iPhone 6 plus and I like them both almost equally. I am trying to decide whether I want the iPhone 6S coming September or the G4. There's something about the way the iPhone feels. You can feel how well made they are and actually examine it to find it to be seamless and perfect. The G3 being plastic and having the removable back fails to have those qualities. I'd like to see a G4 that has a metal body and cut the sh*t with the removable battery. Give me a good one battery that keeps a charge and doesn't need to come out! I have to say that the way the G3 is shaped fits better I'm your hand so there should be plenty of room for a giant battery. As for iOS and Android Lolipop, I love them both and hate them both for obvious reasons.

I think making the power button the scanner is a great idea. When holding the phone, my pointer finger lines up nicely with the power button and volume rocker.
