How to Download and Install Android 7 Nougat on HTC Desire 820
If you own an HTC Desire 820 smartphone and want to upgrade it to the latest Android 7 Nougat operating system, you might be wondering how to do it. Android 7 Nougat brings many new features and improvements, such as split-screen mode, quick settings, notification dots, smart text selection, picture-in-picture mode, and more. However, HTC has not officially released the Android 7 Nougat update for the HTC Desire 820, which means you have to rely on custom ROMs to get it.
In this article, we will show you how to download and install Android 7 Nougat on HTC Desire 820 using a custom ROM called LineageOS 14.1. LineageOS is one of the most popular and stable custom ROMs for Android devices, based on the CyanogenMod project. It offers a pure Android experience with some extra features and customization options. Before you proceed, please note that installing a custom ROM will void your warranty and may cause data loss or damage to your device. Therefore, you should backup your data and follow the instructions carefully at your own risk.
