Android 5.0/5.1 Lollipop


Android 5.0, codenamed “Lollipop,” marked a significant evolution in the Android saga. Released in November 2014, Lollipop introduced a complete visual overhaul with the “Material Design” language, emphasizing consistent design, interactive animations, and depth effects.


After the optimization-focused KitKat, Google aimed to redefine the Android aesthetic and user experience with Lollipop. Material Design was a response to the need for a unified, intuitive, and visually appealing design language that could be applied across devices and platforms.


Lollipop was a transformative update, introducing the Material Design philosophy, which brought cohesive animations, depth effects, and a vibrant color palette. The platform also emphasized enhanced notifications, improved battery life, and new device-sharing capabilities.

First devices to receive the update:

The Nexus 6 (smartphone) and Nexus 9 (tablet) were the flagship devices for Lollipop, showcasing the platform’s new design and features.


Android 5.0/5.1 Lollipop introduced a myriad of features:

  • Material Design: A new design language that emphasized consistent animations, depth effects, and a bold color palette.
  • Enhanced Notifications: Notifications became more interactive and were accessible from the lock screen.
  • Battery Saver Mode: This feature aimed to extend device battery life by limiting background processes.
  • Multiple User Accounts: Lollipop introduced the ability to create multiple user accounts on a single device.
  • Guest Mode: Users could create a guest profile, ensuring their personal data remained private.
  • Device Protection: If lost or stolen, devices remained locked until the user signed in with their Google account.
  • Improved Connectivity: Enhanced support for Bluetooth Low Energy and a revised quick settings menu.

User Experience:

Lollipop aimed to provide a fresh, consistent, and intuitive user experience. Material Design’s principles ensured that interactions felt natural and predictable. The enhanced notifications, battery saver mode, and device-sharing features further elevated the daily user experience.


Lollipop, while building on the Linux kernel, was a significant departure in terms of design and user experience. The introduction of Material Design set a new standard for Android apps, pushing developers to adopt this new design philosophy.


Lollipop took substantial steps in enhancing device security. The introduction of device protection ensured that lost or stolen devices remained inaccessible without proper authentication. The platform also introduced Smart Lock, allowing users to set trusted places, devices, or faces to keep their device unlocked.


Android 5.0/5.1 Lollipop was generally well-received. The introduction of Material Design was particularly praised, with many appreciating the fresh, modern aesthetic. However, like any major update, Lollipop had its share of initial bugs, which were addressed in subsequent updates.
