how many megapixels does a samsung galaxy s8 have
Samsung Galaxy S8 Unlike past Galaxy S series models, the S8 line does not feature physical navigation keys, electing to use on-screen keys instead.[20] However, unlike other implementations, the home button can still be activated if it is hidden or the screen is off. The S8's display features pressure sensitivity limited to the home button.[57] To prevent the home button from burn-in damage, its position moves slightly.[58][59] While The Verge claims that the S8 uses exactly the same 12-megapixel rear camera as the S7, though with software improvements,[20] a report from PhoneArena claims that the phones carry new, custom camera modules.[60] The front-facing camera was upgraded to an 8-megapixel sensor with autofocus.[20][61] The S8 features fingerprint and iris scanners; the fingerprint reader is relocated to the rear of the device, to the left of the camera, due to the removal of the physical home button.[20] In addition to an iris scanner, the S8 also features face-scanning as an option to unlock the phone.[62][63] Face recognition technology had previously been implemented in earlier models since the Galaxy S III.[64]
