Install Android 12 ROM and TWRP on Galaxy S7 Edge

In this guide, we will show you the steps to install TWRP Recovery and then the Android 12 ROM onto your Galaxy S7 Edge. Thanks to its unique design, this device managed to ‘edge’ out both its counterpart- the regular S7 and its Plus variant. Along the same lines, the device came with Android 6 out of the box and got its fair share of two Android upgrades. So if you are currently in the stock environment, then your device might be running the Android 8.0 Oreo as of now.

But thanks to the open-source nature of the OS, you could now welcome the twelfth OS build onto your device.  The developers have ported the LineageOS 19, one of the most popular names in the custom ROM domain, onto the S7 Edge. So you are now guaranteed a decent level of customizations and feature set and at the same time, a stable ecosystem to work in. On that note, let’s now start off with the steps to install TWRP Recovery and then the Android 12 ROM onto your Galaxy S7 Edge device.

What’s New in Android 12?

Just to recap, the Silicon Valley giants have introduced a plethora of new and interesting features in the twelfth iteration of the OS. These include the massive UI revamp thanks to the Material You design. Likewise, there’s a Wallpaper-based UX Theming that will pick up the major color from the wallpaper and theme it across various device components (such as the Notifications panel and Settings menu). Then there is an addition of the Privacy Dashboard as well.

This will tell you the date and time when an app asked for the location, camera, and microphone permissions. Moreover, there are some new accessibility features as well. These include the likes of Camera Switch which allows you to take full control of your device via your facial gestures. And you could now welcome all these features onto your device. Given here are the detailed instructions to install Android 12 ROM on your Galaxy S7 Edge device.
