Android was acquired by Google in 2005, marking a significant turning point for the platform. It evolved from an open-source operating system that encouraged diverse hardware options to a dominant mobile OS, adapting to consumer demands for larger screens and advanced features. Between 2018 and 2020, manufacturers began adopting edge-to-edge displays, leading to innovations like the "notch" and "punch-hole" designs. From 2021 onward, foldable phones emerged, with devices like the Samsung Galaxy Z Fold and Z Flip redefining the smartphone form factor. Google introduced optimizations for large screens and improved multitasking capabilities to accommodate these changes.
