Android offers countless customization possibilities to its users. Let's have a look at the most prominent ones:

• Home screen: Android’s Home screen doesn't follow a rigid layout, so users can arrange app icons in any chosen pattern. They can also add widgets, calendars, different time displays, and other features.
• Launcher Apps: Apps like Nova and Niagara allow users to change the look of Android completely. For example, they allow users to add more icons to the dock, have wallpapers that change over time, or use custom navigation gestures.
• Default apps: Users can set a default app for many tasks: messaging, emailing, browsing, typing, and calling.
• Dual messaging: Samsung offers Dual messenger on their dual-SIM Android phones. It lets you use two different accounts with one chatting app like WhatsApp or Viber.
• Installing apps without the Play Store: Android allows users to install apps through third-party app stores like Amazon's App Store or manually by downloading APKs.
• Android rooting: Rooting an Android device gives users unrestricted access to the system files so that they can modify the software code. However, many apps (like banking apps, Google Pay, and some games) may not work on rooted devices due to security concerns. It also voids warranties on most devices and can lead to system instability if done incorrectly.
