Recently, many rumours have pointed to a saying that Apple was trying to set the sensor to another side to make it invisible - under the front screen , or maybe on the rear.
What shocks us is now it seems that maybe Touch ID will be abandoned entirely.
The KGI analyst Ming-Chi Kuo, who has sent out a report with his top predictions for the 2017 iPhone lineup claimed that.
Within his predition, the iPhone 8 will aim at 'the highest screen-to-body ratio of any phone on the market', thanks to the addition of the 'notch' at the top of the screen and a virtual home button.
'We predict the OLED model won't support fingerprint recognition, reasons being: the full-screen design doesn't work with existing capacitive fingerprint recognition, and the scan-through ability of the under-display fingerprint solution still has technical challenges'
He also claims the last minutes change will not mean delays.
'As the new OLED iPhone won't support under-display fingerprint recognition, we now do not expect production ramp-up will be delayed again (we previously projected the ramp-up would be postponed to late October or later).'
Kuo says he expects the handset to have 3D sensing for facial recognition to allow the facial scannimg and to make Apple's recently announced augmented reality software more accurate.
Kuo also claims the handset will still be published in September, alongside two models without the OLED screen.
'For optimized promotional effect, we think Apple may unveil the three models simultaneously in September, though the launch date of the OLED version may trail that of LCD models, and supply tightness may not improve before 1H18.'
The two LCD phones will have standard 4.7-inch and 5.5-inch screens, with the front face like the current iPhone 7 and iPhone 7 Plus.
However the iPhone 8 chassis will be made of stainless steel and glass, while it is believed the 'iPhone 7s' devices will have glass backs and an aluminium front board.
Rumours about the iPhone 8 never stop for months, and a new video released last week claims to give the 'closet look' at the device yet.
In another aspect, Apple and Samsung have been battling it out to design the perfect fingerprint sensor and although Samsung was the first to relocate it, it is not in an ideal place for consumers.
Because the Galaxy S8 family is designed with the fingerprint scanner on the back to make room for the edge-to-edge screen, some users have found that the rear-camera is being constantly smudged, as you have to 'poke around to locate it'.
Although many rumors are surrounding Apple's highly-anticipating iPhone 8, They are just rumors. Whether Touch ID will dissapear or facial recognition will show up on iPhone 8, before its launch, it needs more details.
