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]
Samsung Galaxy S5 The Samsung Galaxy S5 is an Android smartphone produced by Samsung Electronics. Unveiled on 24 February 2014 at Mobile World Congress in Barcelona, Spain, it was released on 11 April 2014 in 150 countries as the immediate successor to the Galaxy S4. As with the S4, the S5 is an evolution of the prior year's model, placing a particular emphasis on an improved build with a textured rear cover and IP67 certification for dust and water resistance, a more refined user experience, new security features such as a fingerprint reader and private mode, expanded health features (such as a built-in heart rate monitor), and an updated camera.
