Answer 1

Answer:

$\huge \frak \blue{answer}$

Most camera phones are smaller and simpler than separate digital cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010 and decline thereafter. Most model lines improve their cameras every year or two. For example, the Samsung Galaxy S8's camera was nearly identical to its predecessor's, while updated on the succeeding Samsung Galaxy S9.

Most modern smartphones only have a menu choice to start a camera application program and an on-screen button to activate the shutter.[2] Some also have a separate camera button, for quickness and convenience. Few mobile phones such as the 2009 Samsung i8000 Omnia II have a two-level shutter button to resemble the point-and-shoot intuition from dedicated digital cameras.[3] A few camera phones are designed to resemble separate low-end digital compact cameras in appearance and to some degree in features and picture quality, and are branded as both mobile phones and cameras.
