System Updates: Scroll down to About Phone or About Tablet, then tap System Updates (or Software Update).
Check for Update: Tap the button to check. If 5.1.1 is available, follow the prompts to download and install. 2. Manual Download (Firmware/Factory Images)

Google Nexus/Pixel Devices: Google provides an official archive of Factory Images for Nexus Devices.
Other Manufacturers: For Samsung, LG, or Motorola, you generally must use third-party tools like Sammobile (for Samsung) or Sony Flash Tool.
Custom ROMs: If your device never officially received 5.1.1, developers on forums like XDA Developers often create custom versions (like LineageOS) based on that Android version. 3. Key Features of Android 5.1.1
If you are writing content about this update, here are the highlights:
Device Protection: Improved security that keeps your device locked even if it's factory reset (requires your Google login).

Bug Fixes: Significant fixes for memory leaks that were present in earlier 5.0 versions. ⚠️ Important Warning
